bitcoin support number washington. ⑧③③-⑨⓪②-②④⓪⓪ Bitcoin for the most part alluded to as a digital currency, a virtual money, or possibly an electronic money - is a sort of money that is virtual.It's like an online variation of money. You can utilize it to buy administrations and items, however not many stores acknowledge Bitcoin yet, and a few nations have prohibited it completely.
Each Bitcoin it's generally a PC record that is kept in a' computerized wallet' application with a cell phone or maybe laptop.Individuals can convey Bitcoins (or perhaps part of one) in your advanced wallet, and furthermore you can send Bitcoins to others.
Each exchange is caught in an open rundown known as the blockchain.It is then simple to follow the tale of Bitcoins to keep individuals from spending coins they don't wear, making duplicates, or perhaps fix in exchanges. bitcoin support number washington.
You will discover three essential ways people get Bitcoins.You can buy Bitcoins utilizing' genuine' cash.You can offer things and let individuals pay out with Bitcoins.Or they could be made utilizing a PC.
For your Bitcoin telephone framework to work, individuals can make their PC procedure exchanges for everybody.Computer frameworks exist, working out confused wholes. In some cases they're remunerated with a Bitcoin in light of the proprietor to hold.Most individuals make ground-breaking PCs basically to attempt to get Bitcoins. This' known as mining.
In any case, the totals are beginning to be more and harder to stop such a large number of Bitcoins being generated.In case you started mining now,bitcoin support number washington. it might be numerous prior years you got one Bitcoin.You may end up spending more cash on electrical force for your PC or PC than the Bitcoin will be justified, despite all the trouble.
Bitcoins are advantageous on the grounds that people are slanted to trade them for real administrations and merchandise, and even money.There are a lot of things other than money, which we consider significant, similar to precious stones and gold. The Aztecs utilized cocoa beans as cash!
Every exchange is reported openly, so it is difficult to duplicate Bitcoins, make counterfeit ones, or even spend individuals you don't wear.It's conceivable to lose the Bitcoin wallet of yours or erase the Bitcoins of yours and lose them uncertainly. There additionally have been burglaries from destinations that permit you to keep your Bitcoins remotely.
Bitcoins empowers you to buy stock. Likewise, universal installments are modest and simple on the grounds that bitcoins aren't attached to any nation or guideline. May be private companies like them since you will discover no charges of Credit card. Trusting that they will move in esteem, a few people buy bitcoins being a speculation.
Buy on an Exchange Many commercial centers known as bitcoin trades empower individuals to buy or sell bitcoins utilizing different monetary standards. Coinbase is a top trade, adjacent to Bitfinex and Bitstamp. However, the worry is security: Bitcoins well worth several millions dollars have been taken from Bitfinex when it was hacked in 2016.
Bitcoins are kept in a computerized wallet that is available potentially in the cloud or maybe for a client's PC framework. The wallet resembles a virtual financial balance that permits clients to convey or get bitcoins, pay for items, or set aside their cash. Not at all like financial balance profiles, bitcoin wallets are not safeguarded through the FDIC. bitcoin support number washington.
Bitcoin is by means of Bitcoin mining - the way toward making new coins are made, and exchange data is checked. Mining is finished by powerful PCs that take care of muddled scientific issues. Diggers are compensated Bitcoin each time they remember a creative square of exchanges for the blockchain.
One of the most critical use cases which Bitcoin has is similar to a retail chain of significant worth. This may look absurd when we have just been talking about it smashing, yet only hear me out there!
Bitcoin fundamentally would make a huge store of worth in its current structure hypothetically. The sole explanation it's not carrying on like you is down to individuals' naivety and ravenousness about what it's and why it's significant. Thus the significance itself makes light of an imperative job the street of Bitcoin. bitcoin support number washington.
It has been contrasted with electronic gold by the fellow benefactor of Apple, Steve Wozniak. It carries on better contrasted with gold in manners that are some moreover. It is less confused to store, it is simpler to ship, it can't be considered from you by pressure, and the amount is known. Gold is precarious for practically every one of these reasons.
At the point when you are endeavoring to get a handle on unequivocally why something you can't see (Bitcoin) could be spoken about in a similar manner as Gold, at that point permit me to explain something about the significance that makes light of a noteworthy job the street of Bitcoin.

Dive Into Tendermint Consensus Protocol (I)

Dive Into Tendermint Consensus Protocol (I)
This article is written by the CoinEx Chain lab. CoinEx Chain is the world’s first public chain exclusively designed for DEX, and will also include a Smart Chain supporting smart contracts and a Privacy Chain protecting users’ privacy.
longcpp @ 20200618
This is Part 1 of the serialized articles aimed to explain the Tendermint consensus protocol in detail.
Part 1. Preliminary of the consensus protocol: security model and PBFT protocol
Part 2. Tendermint consensus protocol illustrated: two-phase voting protocol and the locking and unlocking mechanism
Part 3. Weighted round-robin proposer selection algorithm used in Tendermint project
Any consensus agreement that is ultimately reached is the General Agreement, that is, the majority opinion. The consensus protocol on which the blockchain system operates is no exception. As a distributed system, the blockchain system aims to maintain the validity of the system. Intuitively, the validity of the blockchain system has two meanings: firstly, there is no ambiguity, and secondly, it can process requests to update its status. The former corresponds to the safety requirements of distributed systems, while the latter to the requirements of liveness. The validity of distributed systems is mainly maintained by consensus protocols, considering the multiple nodes and network communication involved in such systems may be unstable, which has brought huge challenges to the design of consensus protocols.

The semi-synchronous network model and Byzantine fault tolerance

Researchers of distributed systems characterize these problems that may occur in nodes and network communications using node failure models and network models. The fail-stop failure in node failure models refers to the situation where the node itself stops running due to configuration errors or other reasons, thus unable to go on with the consensus protocol. This type of failure will not cause side effects on other parts of the distributed system except that the node itself stops running. However, for such distributed systems as the public blockchain, when designing a consensus protocol, we still need to consider the evildoing intended by nodes besides their failure. These incidents are all included in the Byzantine Failure model, which covers all unexpected situations that may occur on the node, for example, passive downtime failures and any deviation intended by the nodes from the consensus protocol. For a better explanation, downtime failures refer to nodes’ passive running halt, and the Byzantine failure to any arbitrary deviation of nodes from the consensus protocol.
Compared with the node failure model which can be roughly divided into the passive and active models, the modeling of network communication is more difficult. The network itself suffers problems of instability and communication delay. Moreover, since all network communication is ultimately completed by the node which may have a downtime failure or a Byzantine failure in itself, it is usually difficult to define whether such failure arises from the node or the network itself when a node does not receive another node's network message. Although the network communication may be affected by many factors, the researchers found that the network model can be classified by the communication delay. For example, the node may fail to send data packages due to the fail-stop failure, and as a result, the corresponding communication delay is unknown and can be any value. According to the concept of communication delay, the network communication model can be divided into the following three categories:
  • The synchronous network model: There is a fixed, known upper bound of delay $\Delta$ in network communication. Under this model, the maximum delay of network communication between two nodes in the network is $\Delta$. Even if there is a malicious node, the communication delay arising therefrom does not exceed $\Delta$.
  • The asynchronous network model: There is an unknown delay in network communication, with the upper bound of the delay known, but the message can still be successfully delivered in the end. Under this model, the network communication delay between two nodes in the network can be any possible value, that is, a malicious node, if any, can arbitrarily extend the communication delay.
  • The semi-synchronous network model: Assume that there is a Global Stabilization Time (GST), before which it is an asynchronous network model and after which, a synchronous network model. In other words, there is a fixed, known upper bound of delay in network communication $\Delta$. A malicious node can delay the GST arbitrarily, and there will be no notification when no GST occurs. Under this model, the delay in the delivery of the message at the time $T$ is $\Delta + max(T, GST)$.
The synchronous network model is the most ideal network environment. Every message sent through the network can be received within a predictable time, but this model cannot reflect the real network communication situation. As in a real network, network failures are inevitable from time to time, causing the failure in the assumption of the synchronous network model. Yet the asynchronous network model goes to the other extreme and cannot reflect the real network situation either. Moreover, according to the FLP (Fischer-Lynch-Paterson) theorem, under this model if there is one node fails, no consensus protocol will reach consensus in a limited time. In contrast, the semi-synchronous network model can better describe the real-world network communication situation: network communication is usually synchronous or may return to normal after a short time. Such an experience must be no stranger to everyone: the web page, which usually gets loaded quite fast, opens slowly every now and then, and you need to try before you know the network is back to normal since there is usually no notification. The peer-to-peer (P2P) network communication, which is widely used in blockchain projects, also makes it possible for a node to send and receive information from multiple network channels. It is unrealistic to keep blocking the network information transmission of a node for a long time. Therefore, all the discussion below is under the semi-synchronous network model.
The design and selection of consensus protocols for public chain networks that allow nodes to dynamically join and leave need to consider possible Byzantine failures. Therefore, the consensus protocol of a public chain network is designed to guarantee the security and liveness of the network under the semi-synchronous network model on the premise of possible Byzantine failure. Researchers of distributed systems point out that to ensure the security and liveness of the system, the consensus protocol itself needs to meet three requirements:
  • Validity: The value reached by honest nodes must be the value proposed by one of them
  • Agreement: All honest nodes must reach consensus on the same value
  • Termination: The honest nodes must eventually reach consensus on a certain value
Validity and agreement can guarantee the security of the distributed system, that is, the honest nodes will never reach a consensus on a random value, and once the consensus is reached, all honest nodes agree on this value. Termination guarantees the liveness of distributed systems. A distributed system unable to reach consensus is useless.

The CAP theorem and Byzantine Generals Problem

In a semi-synchronous network, is it possible to design a Byzantine fault-tolerant consensus protocol that satisfies validity, agreement, and termination? How many Byzantine nodes can a system tolerance? The CAP theorem and Byzantine Generals Problem provide an answer for these two questions and have thus become the basic guidelines for the design of Byzantine fault-tolerant consensus protocols.
Lamport, Shostak, and Pease abstracted the design of the consensus mechanism in the distributed system in 1982 as the Byzantine Generals Problem, which refers to such a situation as described below: several generals each lead the army to fight in the war, and their troops are stationed in different places. The generals must formulate a unified action plan for the victory. However, since the camps are far away from each other, they can only communicate with each other through the communication soldiers, or, in other words, they cannot appear on the same occasion at the same time to reach a consensus. Unfortunately, among the generals, there is a traitor or two who intend to undermine the unified actions of the loyal generals by sending the wrong information, and the communication soldiers cannot send the message to the destination by themselves. It is assumed that each communication soldier can prove the information he has brought comes from a certain general, just as in the case of a real BFT consensus protocol, each node has its public and private keys to establish an encrypted communication channel for each other to ensure that its messages will not be tampered with in the network communication, and the message receiver can also verify the sender of the message based thereon. As already mentioned, any consensus agreement ultimately reached represents the consensus of the majority. In the process of generals communicating with each other for an offensive or retreat, a general also makes decisions based on the majority opinion from the information collected by himself.
According to the research of Lamport et al, if there are 1/3 or more traitors in the node, the generals cannot reach a unified decision. For example, in the following figure, assume there are 3 generals and only 1 traitor. In the figure on the left, suppose that General C is the traitor, and A and B are loyal. If A wants to launch an attack and informs B and C of such intention, yet the traitor C sends a message to B, suggesting what he has received from A is a retreat. In this case, B can't decide as he doesn't know who the traitor is, and the information received is insufficient for him to decide. If A is a traitor, he can send different messages to B and C. Then C faithfully reports to B the information he received. At this moment as B receives conflicting information, he cannot make any decisions. In both cases, even if B had received consistent information, it would be impossible for him to spot the traitor between A and C. Therefore, it is obvious that in both situations shown in the figure below, the honest General B cannot make a choice.
According to this conclusion, when there are $n$ generals with at most $f$ traitors (n≤3f), the generals cannot reach a consensus if $n \leq 3f$; and with $n > 3f$, a consensus can be reached. This conclusion also suggests that when the number of Byzantine failures $f$ exceeds 1/3 of the total number of nodes $n$ in the system $f \ge n/3$ , no consensus will be reached on any consensus protocol among all honest nodes. Only when $f < n/3$, such condition is likely to happen, without loss of generality, and for the subsequent discussion on the consensus protocol, $ n \ge 3f + 1$ by default.
The conclusion reached by Lamport et al. on the Byzantine Generals Problem draws a line between the possible and the impossible in the design of the Byzantine fault tolerance consensus protocol. Within the possible range, how will the consensus protocol be designed? Can both the security and liveness of distributed systems be fully guaranteed? Brewer provided the answer in his CAP theorem in 2000. It indicated that a distributed system requires the following three basic attributes, but any distributed system can only meet two of the three at the same time.
  1. Consistency: When any node responds to the request, it must either provide the latest status information or provide no status information
  2. Availability: Any node in the system must be able to continue reading and writing
  3. Partition Tolerance: The system can tolerate the loss of any number of messages between two nodes and still function normally

https://preview.redd.it/1ozfwk7u7m851.png?width=1400&format=png&auto=webp&s=fdee6318de2cf1c021e636654766a7a0fe7b38b4
A distributed system aims to provide consistent services. Therefore, the consistency attribute requires that the two nodes in the system cannot provide conflicting status information or expired information, which can ensure the security of the distributed system. The availability attribute is to ensure that the system can continuously update its status and guarantee the availability of distributed systems. The partition tolerance attribute is related to the network communication delay, and, under the semi-synchronous network model, it can be the status before GST when the network is in an asynchronous status with an unknown delay in the network communication. In this condition, communicating nodes may not receive information from each other, and the network is thus considered to be in a partitioned status. Partition tolerance requires the distributed system to function normally even in network partitions.
The proof of the CAP theorem can be demonstrated with the following diagram. The curve represents the network partition, and each network has four nodes, distinguished by the numbers 1, 2, 3, and 4. The distributed system stores color information, and all the status information stored by all nodes is blue at first.
  1. Partition tolerance and availability mean the loss of consistency: When node 1 receives a new request in the leftmost image, the status changes to red, the status transition information of node 1 is passed to node 3, and node 3 also updates the status information to red. However, since node 3 and node 4 did not receive the corresponding information due to the network partition, the status information is still blue. At this moment, if the status information is queried through node 2, the blue returned by node 2 is not the latest status of the system, thus losing consistency.
  2. Partition tolerance and consistency mean the loss of availability: In the middle figure, the initial status information of all nodes is blue. When node 1 and node 3 update the status information to red, node 2 and node 4 maintain the outdated information as blue due to network partition. Also when querying status information through node 2, you need to first ask other nodes to make sure you’re in the latest status before returning status information as node 2 needs to follow consistency, but because of the network partition, node 2 cannot receive any information from node 1 or node 3. Then node 2 cannot determine whether it is in the latest status, so it chooses not to return any information, thus depriving the system of availability.
  3. Consistency and availability mean the loss of the partition tolerance: In the right-most figure, the system does not have a network partition at first, and both status updates and queries can go smoothly. However, once a network partition occurs, it degenerates into one of the previous two conditions. It is thus proved that any distributed system cannot have consistency, availability, and partition tolerance all at the same time.

https://preview.redd.it/456x2blv7m851.png?width=1400&format=png&auto=webp&s=550797373145b8fc1471bdde68ed5f8d45adb52b
The discovery of the CAP theorem seems to declare that the aforementioned goals of the consensus protocol is impossible. However, if you’re careful enough, you may find from the above that those are all extreme cases, such as network partitions that cause the failure of information transmission, which could be rare, especially in P2P network. In the second case, the system rarely returns the same information with node 2, and the general practice is to query other nodes and return the latest status as believed after a while, regardless of whether it has received the request information of other nodes. Therefore, although the CAP theorem points out that any distributed system cannot satisfy the three attributes at the same time, it is not a binary choice, as the designer of the consensus protocol can weigh up all the three attributes according to the needs of the distributed system. However, as the communication delay is always involved in the distributed system, one always needs to choose between availability and consistency while ensuring a certain degree of partition tolerance. Specifically, in the second case, it is about the value that node 2 returns: a probably outdated value or no value. Returning the possibly outdated value may violate consistency but guarantees availability; yet returning no value deprives the system of availability but guarantees its consistency. Tendermint consensus protocol to be introduced is consistent in this trade-off. In other words, it will lose availability in some cases.
The genius of Satoshi Nakamoto is that with constraints of the CAP theorem, he managed to reach a reliable Byzantine consensus in a distributed network by combining PoW mechanism, Satoshi Nakamoto consensus, and economic incentives with appropriate parameter configuration. Whether Bitcoin's mechanism design solves the Byzantine Generals Problem has remained a dispute among academicians. Garay, Kiayias, and Leonardos analyzed the link between Bitcoin mechanism design and the Byzantine consensus in detail in their paper The Bitcoin Backbone Protocol: Analysis and Applications. In simple terms, the Satoshi Consensus is a probabilistic Byzantine fault-tolerant consensus protocol that depends on such conditions as the network communication environment and the proportion of malicious nodes' hashrate. When the proportion of malicious nodes’ hashrate does not exceed 1/2 in a good network communication environment, the Satoshi Consensus can reliably solve the Byzantine consensus problem in a distributed environment. However, when the environment turns bad, even with the proportion within 1/2, the Satoshi Consensus may still fail to reach a reliable conclusion on the Byzantine consensus problem. It is worth noting that the quality of the network environment is relative to Bitcoin's block interval. The 10-minute block generation interval of the Bitcoin can ensure that the system is in a good network communication environment in most cases, given the fact that the broadcast time of a block in the distributed network is usually just several seconds. In addition, economic incentives can motivate most nodes to actively comply with the agreement. It is thus considered that with the current Bitcoin network parameter configuration and mechanism design, the Bitcoin mechanism design has reliably solved the Byzantine Consensus problem in the current network environment.

Practical Byzantine Fault Tolerance, PBFT

It is not an easy task to design the Byzantine fault-tolerant consensus protocol in a semi-synchronous network. The first practically usable Byzantine fault-tolerant consensus protocol is the Practical Byzantine Fault Tolerance (PBFT) designed by Castro and Liskov in 1999, the first of its kind with polynomial complexity. For a distributed system with $n$ nodes, the communication complexity is $O(n2$.) Castro and Liskov showed in the paper that by transforming centralized file system into a distributed one using the PBFT protocol, the overwall performance was only slowed down by 3%. In this section we will briefly introduce the PBFT protocol, paving the way for further detailed explanations of the Tendermint protocol and the improvements of the Tendermint protocol.
The PBFT protocol that includes $n=3f+1$ nodes can tolerate up to $f$ Byzantine nodes. In the original paper of PBFT, full connection is required among all the $n$ nodes, that is, any two of the n nodes must be connected. All the nodes of the network jointly maintain the system status through network communication. In the Bitcoin network, a node can participate in or exit the consensus process through hashrate mining at any time, which is managed by the administrator, and the PFBT protocol needs to determine all the participating nodes before the protocol starts. All nodes in the PBFT protocol are divided into two categories, master nodes, and slave nodes. There is only one master node at any time, and all nodes take turns to be the master node. All nodes run in a rotation process called View, in each of which the master node will be reelected. The master node selection algorithm in PBFT is very simple: all nodes become the master node in turn by the index number. In each view, all nodes try to reach a consensus on the system status. It is worth mentioning that in the PBFT protocol, each node has its own digital signature key pair. All sent messages (including request messages from the client) need to be signed to ensure the integrity of the message in the network and the traceability of the message itself. (You can determine who sent a message based on the digital signature).
The following figure shows the basic flow of the PBFT consensus protocol. Assume that the current view’s master node is node 0. Client C initiates a request to the master node 0. After the master node receives the request, it broadcasts the request to all slave nodes that process the request of client C and return the result to the client. After the client receives f+1 identical results from different nodes (based on the signature value), the result can be taken as the final result of the entire operation. Since the system can have at most f Byzantine nodes, at least one of the f+1 results received by the client comes from an honest node, and the security of the consensus protocol guarantees that all honest nodes will reach consensus on the same status. So, the feedback from 1 honest node is enough to confirm that the corresponding request has been processed by the system.

For the status synchronization of all honest nodes, the PBFT protocol has two constraints on each node: on one hand, all nodes must start from the same status, and on the other, the status transition of all nodes must be definite, that is, given the same status and request, the results after the operation must be the same. Under these two constraints, as long as the entire system agrees on the processing order of all transactions, the status of all honest nodes will be consistent. This is also the main purpose of the PBFT protocol: to reach a consensus on the order of transactions between all nodes, thereby ensuring the security of the entire distributed system. In terms of availability, the PBFT consensus protocol relies on a timeout mechanism to find anomalies in the consensus process and start the View Change protocol in time to try to reach a consensus again.
The figure above shows a simplified workflow of the PBFT protocol. Where C is the client, 0, 1, 2, and 3 represent 4 nodes respectively. Specifically, 0 is the master node of the current view, 1, 2, 3 are slave nodes, and node 3 is faulty. Under normal circumstances, the PBFT consensus protocol reaches consensus on the order of transactions between nodes through a three-phase protocol. These three phases are respectively: Pre-Prepare, Prepare, and Commit:
  • The master node of the pre-preparation node is responsible for assigning the sequence number to the received client request, and broadcasting the message to the slave node. The message contains the hash value of the client request d, the sequence number of the current viewv, the sequence number n assigned by the master node to the request, and the signature information of the master nodesig. The scheme design of the PBFT protocol separates the request transmission from the request sequencing process, and the request transmission is not to be discussed here. The slave node that receives the message accepts the message after confirming the message is legitimate and enter preparation phase. The message in this step checks the basic signature, hash value, current view, and, most importantly, whether the master node has given the same sequence number to other request from the client in the current view.
  • In preparation, the slave node broadcasts the message to all nodes (including itself), indicating that it assigns the sequence number n to the client request with the hash value d under the current view v, with its signaturesig as proof. The node receiving the message will check the correctness of the signature, the matching of the view sequence number, etc., and accept the legitimate message. When the PRE-PREPARE message about a client request (from the main node) received by a node matches with the PREPARE from 2f slave nodes, the system has agreed on the sequence number requested by the client in the current view. This means that 2f+1 nodes in the current view agree with the request sequence number. Since it contains information from at most fmalicious nodes, there are a total of f+1 honest nodes that have agreed with the allocation of the request sequence number. With f malicious nodes, there are a total of 2f+1 honest nodes, so f+1represents the majority of the honest nodes, which is the consensus of the majority mentioned before.
  • After the node (including the master node and the slave node) receives a PRE-PREPARE message requested by the client and 2f PREPARE messages, the message is broadcast across the network and enters the submission phase. This message is used to indicate that the node has observed that the whole network has reached a consensus on the sequence number allocation of the request message from the client. When the node receives 2f+1 COMMIT messages, there are at least f+1 honest nodes, that is, most of the honest nodes have observed that the entire network has reached consensus on the arrangement of sequence numbers of the request message from the client. The node can process the client request and return the execution result to the client at this moment.
Roughly speaking, in the pre-preparation phase, the master node assigns a sequence number to all new client requests. During preparation, all nodes reach consensus on the client request sequence number in this view, while in submission the consistency of the request sequence number of the client in different views is to be guaranteed. In addition, the design of the PBFT protocol itself does not require the request message to be submitted by the assigned sequence number, but out of order. That can improve the efficiency of the implementation of the consensus protocol. Yet, the messages are still processed by the sequence number assigned by the consensus protocol for the consistency of the distributed system.
In the three-phase protocol execution of the PBFT protocol, in addition to maintaining the status information of the distributed system, the node itself also needs to log all kinds of consensus information it receives. The gradual accumulation of logs will consume considerable system resources. Therefore, the PBFT protocol additionally defines checkpoints to help the node deal with garbage collection. You can set a checkpoint every 100 or 1000 sequence numbers according to the request sequence number. After the client request at the checkpoint is executed, the node broadcasts messages throughout the network, indicating that after the node executes the client request with sequence number n, the hash value of the system status is d, and it is vouched by its own signature sig. After 2f+1 matching CHECKPOINT messages (one of which can come from the node itself) are received, most of the honest nodes in the entire network have reached a consensus on the system status after the execution of the client request with the sequence numbern, and then you can clear all relevant log records of client requests with the sequence number less than n. The node needs to save these2f+1 CHECKPOINTmessages as proof of the legitimate status at this moment, and the corresponding checkpoint is called a stable checkpoint.
The three-phase protocol of the PBFT protocol can ensure the consistency of the processing order of the client request, and the checkpoint mechanism is set to help nodes perform garbage collection and further ensures the status consistency of the distributed system, both of which can guarantee the security of the distributed system aforementioned. How is the availability of the distributed system guaranteed? In the semi-synchronous network model, a timeout mechanism is usually introduced, which is related to delays in the network environment. It is assumed that the network delay has a known upper bound after GST. In such condition, an initial value is usually set according to the network condition of the system deployed. In case of a timeout event, besides the corresponding processing flow triggered, additional mechanisms will be activated to readjust the waiting time. For example, an algorithm like TCP's exponential back off can be adopted to adjust the waiting time after a timeout event.
To ensure the availability of the system in the PBFT protocol, a timeout mechanism is also introduced. In addition, due to the potential the Byzantine failure in the master node itself, the PBFT protocol also needs to ensure the security and availability of the system in this case. When the Byzantine failure occurs in the master node, for example, when the slave node does not receive the PRE-PREPARE message or the PRE-PREPARE message sent by the master node from the master node within the time window and is thus determined to be illegitimate, the slave node can broadcast to the entire network, indicating that the node requests to switch to the new view with sequence number v+1. n indicates the request sequence number corresponding to the latest stable checkpoint local to the node, and C is to prove the stable checkpoint 2f+1 legitimate CHECKPOINT messages as aforementioned. After the latest stable checkpoint and before initiating the VIEWCHANGE message, the system may have reached a consensus on the sequence numbers of some request messages in the previous view. To ensure the consistency of these request sequence numbers to be switched in the view, the VIEWCHANGE message needs to carry this kind of the information to the new view, which is also the meaning of the P field in the message. P contains all the client request messages collected at the node with a request sequence number greater than n and the proof that a consensus has been reached on the sequence number in the node: the legitimate PRE-PREPARE message of the request and 2f matching PREPARE messages. When the master node in view v+1 collects 2f+1 VIEWCHANGE messages, it can broadcast the NEW-VIEW message and take the entire system into a new view. For the security of the system in combination with the three-phase protocol of the PBFT protocol, the construction rules of the NEW-VIEW information are designed in a quite complicated way. You can refer to the original paper of PBFT for more details.

https://preview.redd.it/x5efdc908m851.png?width=1400&format=png&auto=webp&s=97b4fd879d0ec668ee0990ea4cadf476167a2948
VIEWCHANGE contains a lot of information. For example, C contains 2f+1 signature information, P contains several signature sets, and each set has 2f+1 signature. At least 2f+1 nodes need to send a VIEWCHANGE message before prompting the system to enter the next new view, and that means, in addition to the complex logic of constructing the information of VIEWCHANGE and NEW-VIEW, the communication complexity of the view conversion protocol is $O(n2$.) Such complexity also limits the PBFT protocol to support only a few nodes, and when there are 100 nodes, it is usually too complex to practically deploy PBFT. It is worth noting that in some materials the communication complexity of the PBFT protocol is inappropriately attributed to the full connection between n nodes. By changing the fully connected network topology to the P2P network topology based on distributed hash tables commonly used in blockchain projects, high communication complexity caused by full connection can be conveniently solved, yet still, it is difficult to improve the communication complexity during the view conversion process. In recent years, researchers have proposed to reduce the amount of communication in this step by adopting aggregate signature scheme. With this technology, 2f+1 signature information can be compressed into one, thereby reducing the communication volume during view change.

Gold is a benefit known to man more than a great many ages, Gold and copper were the principal metals utilized by people beginning from 5000 BC, The main enlisted gold found in the US was a piece weighing 7.8kg found in Cabarrus County, North Carolina. At the point when progressively gold was found in little spring glade in 1803, the primary US dash for unheard of wealth started. The world's biggest gold hold is held five stories underground in the vault of the Federal Reserve Bank of New York, it contains 25% of all the gold saves in the world(540,000 gold bars), the greater part of them have a place with remote gov't. The main ever gold candy machine was introduced in Dubai in 2010. Because of its irregularity and high worth, a large portion of the gold at any point mined is still in flowing gold was removed over the most recent 100 years. Numerous individuals inquire as to why gold is so costly, the explanation is its irregularity: more steel is delivered in one hour than gold through the span of the whole mankind's history. Numerous researchers accept that gold is likewise present in Mars, Mercury and Venus.
Reports state China is expanding its gold imports and Mark Mobius, an energetic broker in gold has prompted that individuals buy gold, he accepts that the cost of gold will continue developing as the measure of paper cash in the worldwide economy increments.

Do you realize that under 82% of Americans own any bit of gold?
The exchanging volume of advanced gold is over $100 million
Do you realize you also can put resources into gold?
We should discuss the potential outcomes of putting resources into gold utilizing a blockchain stage, you should have one bit of gold that has a token portrayal,
The explicit explanation on the advanced gold token, what it does and how you can really profit by it.
Presently, in the event that you are following intently, you will find that the crypto showcase hit its top in 2017, in 2017 bitcoin was selling for $20,000 and in 2020, it is coasting around $9,000 and each genuine speculator ought to be seeing this market, at 2017 the complete market capitalization of digital forms of money was nearly $1 Trillion dollars and however it has tumbled to around $300 billion dollars in 2020, this industry despite everything holds a ton of possibilities.
One ought to inquire as to for what reason is there so much venture going into the blockchain space, what is the potential that this thing has, many have named blockchain as web 3.0 or a definitive innovation that will introduce web 3.0, till date, the speculations that have experienced different blockchain new businesses have been over $25 billion dollars with any semblance of EOS, Telegram raising billions of dollars each.
What are the issues associated with putting resources into cryptographic forms of money?
1.Volatility: If you take a gander at the altcoin unsurpassed record, you will see the sickening drop in crypto esteem
What of tasks that have lost over 10000% of their incentive over the course of about two years.
  1. Storage: Knowing which coins to buy and how to store them is a major problem in the digital currency world,crypto-jacking and hacking are at the untouched high as programmers have invaded most internet browsers with coin mining contents and simply a year ago over $1 billion dollars worth of crypto resources were taken from a few trades which thusly constrained them to close their entryways.
To store crypto resources, one is required to safely keep their passwords and their hidden keys as the loss of them mean lost access to their property.

Tokenization
The thought is planned for breaking entire units of stocks, foundation and so forth into littler pictures.
Take one unit of gold and make an advanced unit of it with the blockchain, that thought really birthed the Digital gold token project.
The computerized gold commercial centre: encourages a generally simple, powerful and proficient buy/deal framework, clients can just round out a structure that starts a brilliant agreement, which at that point moves the recently printed GOLD tokens.
Concerning engineers, they are additionally spared the issue of the complexities that accompany coordinating a crypto resource for their foundation, the advanced gold tasks assist them with incorporating without any problem.

Highlights of Digital Gold
The advanced gold token flaunts various highlights that make it one of a kind and beneficial for potential speculators to investigate.
It's a token that is minimal effort and doesn't have move costs when one is moving it, it offers potential speculators the chance to broaden their portfolio while additionally keeping their riches in a place of refuge, it likewise gives secure gold possession as the bought gold is made sure about in a sheltered vault, the computerized gold token is exceptionally fluid, which means there is a business opportunity for you at whatever point you expect to sell or purchase the token since the advanced gold token is attached to real gold, the token is as significant as gold itself, so as gold increments in esteem so does the token.

Helping a friend reopen her business with Bitcoin

A friend of mine owns a hotel inland from Cancun, Mexico and was struggling with expenses related to reopening - if she couldn't foot the upfront cost, she'd go under. I saw an opportunity to help her out and introduce her to Bitcoin, so I offered her a small personal loan on one simple condition: she had to accept it and repay it with Bitcoin.
She's not tech savvy and my Spanish is broken so this was also a test to see how usable the tech is. All told it took just half an hour end-to-end and $0.41 in transaction fees. Got her set up with an Electrum wallet to transfer the BTC, she had a friend with a Bitso account (Mexico's premier bitcoin exchange) to sell the Bitcoin, and she got MX pesos back from him day-of.
Bitcoin was literally the only way this loan could work - I'm U.S. based and each repayment installment was small so Western Union's huge fees made it impossible. The hardest part is still the conversion to local currency (no Bitcoin ATMs were nearby and Local Bitcoins was confusing for her- but Bitso seems like a really intuitive exchange within Mexico). Hopefully that will improve as more businesses accept BTC payments direct.
She's now a Bitcoin user and she got why it's a big deal without any explanation - it was fast, convenient and a lot cheaper than what she's used to

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

Bitcoin Billionaire Reviews : Complete Sign Up Guide [2020]

We as a whole realize what Bitcoin Billionaire Billionaire are, at any rate from a fundamental perspective, and most wise tech darlings have at any rate thought about buying some type of digital money. In case you're among the individuals who are really charmed by all types of cryptographic forms of money, at that point you additionally realize that the arrangement of code which they all sudden spike in demand for is known as a blockchain.
What Are Bitcoin Billionaire Block Explorers?

The chain is persistently getting longer as new squares are finished and get connected as far as possible as another arrangement of recorded information. Each new connection in the chain is included as it happens, giving it an unmistakable straight recipe.
The explanation the blockchain is so productive is on the grounds that it very well may be seen by anybody, yet it can't be duplicated. This permits genuinely open source coding and straightforwardness of information without giving up security.
Envision an information sheet that is copied on each PC that is associated with the web, and afterward envision that updates can be made to this sheet progressively from anyplace on the planet.
These updates will be appeared to everybody seeing it immediately. On the off chance that you can picture that, at that point you have a simple comprehension of how the blockchain functions.

What are Bitcoin and Other Cryptocurrencies Backed By?

Bitcoin was created back in 2009 and became the first cryptocurrency ever designed. Cryptocurrencies have become increasingly popular in the last few years as they offer an efficient and decentralized way of transferring money.
Cryptocurrencies have always been an alternative to banks and fiat money. But why do they have any value at all and who dictates what they are worth? The value of Bitcoin is really calculated through supply and demand. The digital asset itself is backed by nothing more than perhaps the blockchain ledger.
Every single cryptocurrency uses a blockchain ledger, a system that records transactions between two or more parties in a verifiable and permanent way. This certainly adds value to Bitcoin and cryptocurrencies. However, it is not what determines their price.
Why Things Have Value
Why does anything have any value at all? It has mostly because of supply and demand. Traditional currencies, for instance, are only backed by the government that issued them. Digital money, like Bitcoin, is not backed or linked to any physical reserves like gold and can certainly lose value due to different factors.
Cryptocurrencies have value because they require ‘work’ to exist. Cryptocurrencies are maintained thanks to the mining process, a process in which transactions are verified by different people. This process requires a certain amount of work, electricity, and money.
Key Factors That Affect The Value of Cryptocurrencies
Since most cryptocurrencies are not physically backed by anything, their value is determined through supply and demand based on a few important factors. One of the biggest advantages of cryptocurrencies is scarcity. The supply of most cryptocurrencies is fixed, and, unlike traditional currencies, no one can issue more than the maximum limit. This means that cryptocurrencies are deflationary by nature.
Another key factor that benefits cryptocurrencies is divisibility. Any cryptocurrency can be divided into smaller units. A simple change in Bitcoin’s code could allow the digital asset to be divided into infinitely smaller units at any time.
Additionally, transferring cryptocurrencies can be extremely fast and cheap compared to traditional methods. Fees are somewhat fixed no matter the amount you send, which means that theoretically you could send 1 million Bitcoins to someone and pay only a few dollars in fees (or even less).
In a way, one could say that Bitcoin and cryptocurrencies are backed by the public’s faith in them as they have realized that the current monetary system is not as robust as one might think.
Why Are Cryptocurrencies so Volatile Then?
In comparison to traditional currencies and even stocks, cryptocurrencies are far more volatile, meaning that the current price of any given crypto can change drastically in hours. It’s quite common to see Bitcoin’s price go up or down 5-10% within a few days. In fact, even in periods of low volatility, most cryptocurrencies still experience price moves of up to 1-2%, which is considered extremely high in traditional markets.
The explanation, however, is quite simple. Cryptocurrencies, in general, lack the liquidity that the rest of the markets enjoy. According to statistics from Statista, the average daily turnover in the global foreign exchange market was around $6.5 trillion daily. The cryptocurrency market, on average, sees around $80 billion in daily trading volume, and according to various sources, a lot of the volume is actually fake.
The problem with illiquidity is that someone who wants to sell or buy a huge amount of Bitcoin or any cryptocurrency will simply ‘eat’ all the orders in the order book of the exchange, catapulting the price up or crashing it. That is the only reason why cryptocurrencies, in general, are extremely volatile.
Some Cryptocurrencies Are Actually Backed by Things
There are, however, some cryptocurrencies that are backed by gold, assets, and even fiat money. Tether (USDT) became the most popular cryptocurrency backed by fiat, later known as a ‘stablecoin’.
Stablecoins
A stablecoin is designed to always be worth $1.00 by maintaining 1 dollar in some sort of reserve. The first stablecoin to become widely popular was Tether, however, there was a lot of controversy surrounding it. Most of the criticism came from the fact that Tether Limited was unable to prove they actually have the funds to cover all the Tether issued.
Additionally, on 30 April 2019, Tether Limited’s lawyer actually admitted that each coin is only backed by $0.74 in cash.
Currently, there are over a dozen stablecoins that are backed by fiat, commodities, and even cryptocurrencies. TrueUSD is similar to Tether but it is considered to be one of the most reliable stablecoins currently as the company behind it has been extremely transparent and conducted an independent audit back in March 2019.
A more complex stablecoin is Dai, which is backed by Ethereum and pegged to the dollar. The system behind Dai basically locks Ethereum in a public contract. If the value of Dai distances too far from $1, the system will make use of the contract to stabilize it back. There is, however, a small problem: Dai is not entirely decentralized as the technology behind it is being monitored by the Maker Foundation.
DigixDAO is another stablecoin and it’s backed by bars of actual gold. It is an ERC-20 token created back in 2014. The digital asset is entirely decentralized and autonomous and can in fact be extended to be backed by other precious metals and even physical assets. According to the company, the gold is stored in custodial vaults at the Singapore Safe House, and 1 DGX will always equal 1 gram of gold.
Cryptocurrencies Backed by Assets
Not all cryptocurrencies backed by assets are stablecoins. For instance, the first oil-backed cryptocurrency was introduced by Venezuelan President Nicolas Maduro back in 2017. El Petro, although highly criticized, is supposedly the first cryptocurrency to be backed by oil thanks to the country’s huge oil and mineral reserves.
Petro is, however, not pegged to anything, and its value can increase or decrease at any given time.
Tokenization of Assets
Something that has become quite popular over the last few years is the tokenization of traditional stocks and assets. There are countless blockchain startups tokenizing almost anything to represent ownership.
The tokenization of assets brings numerous benefits like greater liquidity, more transparency, cheaper and faster transactions, and more accessibility. Tokenization itself is quite difficult to regulate, and all tokenization assets have to be compliant with the law, something that issuers struggle to achieve.
Conclusion
While traditional cryptocurrencies are not necessarily backed by anything physical, they still hold a lot of value solely based on supply and demand. This is the case with numerous other assets and even fiat money.
Cryptocurrencies have come a long way and there is a wide variety of them. Stablecoins are the most popular when it comes to asset-backed cryptocurrencies. They serve as an alternative to fiat money and bring a lot of liquidity to the market. There are definitely concerns as people question their stability, however, they have become an important factor in the market.
Additionally, other projects aside from stablecoins have implemented asset-backed cryptocurrencies. There are numerous cryptocurrencies out there backed by precious metals, physical assets, stocks, and even other cryptocurrencies. We are definitely going to see even more in the near future as they bring a lot more security to investors and the crypto space in general.

Mining profitability gaining momentum

Mining profitability gaining momentum
We are back!
For the last 2 years there was not much to shill in mining mining was on the life support. And the profits constantly got decreasing. Start of 2020 Bitcoin and Altcoins are showing great performance in price action. This price action has also increased mining profits in some coins for more then 100% since december 2019. It might be to early to say that “we are back” , as crypto can be so unpredictable. But there is a lot of signs that we have now oversold a lot and value of crypto market is increasing steadily. We might see this pattern continue for good bit of times as BTC halving is coming up in 3 month. Let’s get in straight in. I will choose 3 hardware devices which in my opinion would be the best choice and we will see how profitable they are.
If you are new to mining and you want to know which devices to choose, choose from top market cap coins latest equipment. This will be your safest bet, as the mining profits are much more stable on bigger cap coins then on smaller cap coins. If you are small miner and don’t have large electric bills, you can choose smaller cap coins. They might go up in price lot faster then bigger cap coins in bull market, but be aware they they might dump lot faster. It is high risk high reward type of mining.
If you are really serious about mining, you need to look at cheapest power source possible which would be in 0.05c a kw/h range. It is not 2017 and mining from home wont be profitable at 0.30c a kw/h. Industrial power is possible to achieve 0.05 in many places in the world. If it is not possible in your country , look for the country where it is possible. So all profit calculations done for 0.05c a kw/h
Top mining profitability websites :
  • https://www.asicminervalue.com/ It is great website to see newest ASIC miners and their profitability. Usually the new upcoming mining machines gets listed here. So come and checkout this page every few days/weeks this page if you are serious about mining.

The top and 3 most profitable Crypto currencies to mine in February 2020 , for some people miner pick could be different. The prices changes if you are buying new/used , depending in which part of the world are you. This is my recommended , brand new purchase in Europe.
  • Bitcoin – Most suitable Antminer S17+ . It is one of the efficient Bitcoin miner currently publicly available, alternatives would be M20s miner and Avalon miner 1166. Antminer S17 efficiency is 73TH/s @ 3000watts . Current profitability after you have paid your electric bill is 7.82 usd in 24hours , with ROI achievable in 6-7month. It does seems great, but crypto doesn’t stand still. And has plenty of risks.

https://preview.redd.it/msokirj96df41.png?width=891&format=png&auto=webp&s=7552b4aff2c0df4c25d9a72ecc25dfb4c2510f43
  • Ethereum – Best miner to use is RX5700 graphic cards mining rig. I know there is an ASIC miner available A10, but most of you who are in mining will agree with me, that it is complete junk. It is only slightly more efficient then RX5700 gpu rig in terms of price per hash and watt per hash . But it is 10x more riskier investment in mining rig then buying GPU mining rig. So the efficiency of 12xgpu RX5700 mining rig is 640 mh/s @ 1700watts. Current profitability after you have paid your electric bill is 7.62 usd in 24hours , with ROI achievable in about 20-22 month. Ethereum is one of the underdogs which could perform quite well in 2020 and might reduce your ROI much more faster.

https://preview.redd.it/ajx9eyfc6df41.png?width=894&format=png&auto=webp&s=30442d846a9d70ea3eaac6eaf7c2bdbe476384e4
  • DASH – Lately has been released most efficient DASH miner STU-U6. Asic miners are very risky investment, but sometimes they might be very profitable. The beauty of this miner is that it is quite new model and it is mining profitably DASH , even that DASH is still over 90%down from its all time highs. This miner performance is 420GH/s u/2100 watts. Current profitability after you have paid your electric bill is 8.11 usd in 24hours , with ROI achievable in about 5-6 month.

https://preview.redd.it/l80xnwbd6df41.png?width=902&format=png&auto=webp&s=5620ecf7af742cdcae0ae7010cf910d9131ae801
These would be my to pick miners for start of 2020. There is big risks in any on these miners as no high reward investment is guaranteed anywhere. I’ll have more detailed explanation of the risks of each of these miners in my next post.
Any miner suggestion, what would be your best choice and why?

Bitcoin Halving

If you’ve heard the term ‘Bitcoin Halving‘ and have no idea what it means, don’t worry. This article will give you a brief explanation of what the concept is and how it works.
Before we begin, it is important to have some background information. At the core of Bitcoin’s technology is the blockchain. This is essentially a virtual ledger that records all of the coin’s transactions. It keeps records safe and prevents people from spending coins that they no longer own. To maintain such a vast and complex system requires a lot of computing power. This is where ‘miners’ come in.
Miners lend their computing power to help maintain, secure, and record transactions. In exchange, they get rewarded with newly ‘mined’ Bitcoins. Originally, the system allowed for 50 coins to be mined every 10 minutes. However, it is designed to cut that amount in half every 4 years. Since Bitcoin halving has already happened twice in the past, the current amount of Bitcoins mined every 10 minutes stands at 12.5. The next Bitcoin halving is set to happen May 18 of this year.

What effects will Bitcoin Halving have?

The simple answer is: no one knows for sure.
Because the amount of Bitcoins will become more limited or scarce (the last Bitcoin will be mined in 2140), the traditional expectation is that if demand remains constant, as supply decreases, value increases. Yet, when looking back at previous Bitcoin halving events, the reality may be a bit more complicated. The first Bitcoin halving in 2012 did result in prices increasing shortly after. However, the second Bitcoin halving in 2016 actually saw prices initially decreasing, before returning back up and beyond as time went on.
Whether the eventual price increase was simply a delayed reaction to the halving or whether it was caused by other factors, it is hard to say for certain. One argument against the expectation that prices should always go up is the concept of these events being ‘price in’. What this means is that because people expect and know when exactly a Bitcoin halving will happen, they can prepare ahead of time. If people purchase more Bitcoins as an anticipatory measure, prices will already go up even before a Bitcoin halving happens. And so, the event itself would not have any significant effects. Whatever does happen, come May 18th, we will all be watching closely.

What are Bitcoin and Other Cryptocurrencies Backed By?

Bitcoin was created back in 2009 and became the first cryptocurrency ever designed. Cryptocurrencies have become increasingly popular in the last few years as they offer an efficient and decentralized way of transferring money.
Cryptocurrencies have always been an alternative to banks and fiat money. But why do they have any value at all and who dictates what they are worth? The value of Bitcoin is really calculated through supply and demand. The digital asset itself is backed by nothing more than perhaps the blockchain ledger.
Every single cryptocurrency uses a blockchain ledger, a system that records transactions between two or more parties in a verifiable and permanent way. This certainly adds value to Bitcoin and cryptocurrencies. However, it is not what determines their price.
Why Things Have Value
Why does anything have any value at all? It has mostly because of supply and demand. Traditional currencies, for instance, are only backed by the government that issued them.

Can Any Current Crypto Commodity Ever Be Used As A General Currency?

“In the long run, we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean will be flat again.” - John Maynard Keynes

Cryptocurrency Supply Algorithms And The Equation Of Exchange

Although I am a proponent for Bitcoin and view it as a good store-of-value, my belief is that all of the algorithms for cryptocurrency supply models that I have seen to date are not amenable to creating a cryptocurrency useful as a general currency. That is as a means for exchange-of-value as opposed to store-of-value. The following is my brief description of the models that I am aware of, followed by an explanation of why I believe they are not useful for as general currencies. At the bottom, I make a concluding remark on what I believe is a missing feature needed to realize a general currency.

Coin Supply Algorithms

N+1
In an N+1 algorithm, each time a block is produced, a constant incentive reward is added to the supply of coins. This means explicitly that the size of the coin supply will grow forever, unlimited. This sounds pretty good on the surface. If you are a miner, you are guaranteed that there will always be an incentive reward available for mining.
If we look at this from a total coin supply viewpoint, and a little high school math, the normalized change in supply is:
N+1/N
We then want to ask the question, how fast is the coin supply changing, as N goes to infinity since we are assuming that blocks are produced forever. This is:
Lim N->∞ N+1/N
Where N is the number of blocks produced. By L’Hôpital’s rule for those that remember a little highschool calculus (I had to look it up), we can take the derivatives of the numerator and denominator which results in 1/1 = 1. In the limit at infinity, the coin supply is a constant value, even though theoretically it grows forever.
Since infinity is only theoretical, what does this look like for blockchain use cases:
To give a feel for it, imagine that we are at the following 4 stages: 10 blocks have been produced; 100 blocks have been produced; 1000 blocks have been produced, and 10000 blocks have been produced. Adding one reward at each stage gives the following percent change in coin supply:
1 — (10 + 1)/10 = 10%
1 — (100+1)/100 = 1%
1 — (1000+1)/1000 = .1%
1 — (10000+1)/10000 = .01%
This demonstrates that the change in coin supply quickly dwindles to an insignificant amount, even though it continues to grow forever. To put this another way, the addition of each new incentive reward quickly becomes a very small fraction of the total coin supply. The coin supply can be thought of as relatively constant.
N + M*N/2T or N(1+M/2T)
T is units of time in discrete steps, and M is the number of blocks produced at each step. This is essentially the Bitcoin model. To make this clearer let’s assume that there is only 1 block produced at each step. This becomes N + N/2T or N(1+1/2T).
If we replace 2T with a new variable K, then this becomes:
N(1+1/K)
Where K increases forever. The summation of 1/K is the harmonic series and increases forever. Therefore, just like N+1 above, N(1+1/K) or N+N/K also increases forever. As with N+1, the rate of increase of the coin supply is then:
(N(1+1/K))/N
This is more simply 1 + 1/K. Thus, as K grows, we can see that the rate of increase tends towards zero as well. Further, since 1/K becomes a smaller and smaller fraction, eventually representing this as a value in a computer becomes impossible. For example, Bitcoin’s smallest fraction is 1 satoshi. When 1/K becomes smaller than 1 satoshi it will no longer be possible to have an incentive reward for a single block produced.
Given that both coin supply algorithms tend towards a relatively constant supply, in terms of use as a currency, we can view both as essentially equivalent. The only difference is how fast the supply tends towards a constant value, where the Bitcoin model is faster.
N
A third coin supply algorithm is a simple constant amount created in the genesis block. The coins are usually distributed using an airdrop or similar model. Since coins are not being created, the coin supply is by definition constant. If the distribution model used is an incentive reward model to distribute from the pool of coins, it is indistinguishable from one of the above 2 models. If the distribution model is a one-time event, such that all the coins are distributed then there is no incentive reward model.
From a viewpoint of use of currency all 3 models described above can be thought of as equivalent, given enough blocks have been produced for the first 2 models.

Marked To External Asset

There is the fourth model for coin supply which is intended to mark the value of the coin to an external index of some kind. This may be a physical asset like an ounce of gold, or another commodity. In this model, the coin can explicitly represent a unit of the external asset such as an ounce of gold. Regardless of whether the coin can be exchanged for the underlying asset or not, given that supply of commodities such as gold are constantly following the same mining algorithms as above, the marked to asset model is a constant coin supply model. If the distribution model used is an incentive reward model, then it is similar to the third model.

Marked To Value Of External Asset

There is a fifth model for coin supply where the value of the coin is marked to the value of an external asset like the USD, instead of the supply of the external asset, as was the case for marking to a commodity. In this model, the coin supply is changed to reflect the exchange rate of the coin against the value of the external asset. The objective is to keep the exchange rate constant on average over time. For example: assuming the objective is a 1-to-1 exchange between the coin and the USD, then if the coin’s value increases above the objective, more coins are printed, and vice-versa. That is, if the value of the coin decreases, given some means (i.e. burning), the coin supply is decreased to bring the exchange rate towards the objective.
In this model, the coin supply is not fixed but varies with the exchange rate. To the extent that the value of the external asset is relatively constant, and the value of the coin is relatively constant the coin supply will be relatively constant.
Although marking to the USD would seem to be a good idea, given that it is called a “reserve currency”, the USD is intentionally subject to inflation, theoretically, the coin to USD exchange will continue to decrease, requiring the coin supply to be decreased to maintain the objective of a constant exchange rate. Over time, this model can be viewed as decreasing the coin supply if marked to the inflationary external asset value.

Comparing Coin Supply Models

In summary, of the five models described above, four of them are essentially variations on a constant coin supply using various means to distribute the coin, while the fifth tries to keep the value of the coin constant against an external asset value, by managing the supply of the coin.
The equation of exchange: M * V = P * Y[1] tells us that if the amount of money supply, M, (i.e. the coin supply) is constant, and the velocity of money is relatively constant, then an increase in demands for goods (Y), will cause a decrease in the price (P), price deflation. That is, with a fixed coin supply the price of goods is expected to drop, thus increasing the value of the coin. Bitcoin’s increase in value is an example of this. (The Bitcoin ledger does not have the means to determine either prices (P) or goods (Y). Instead, I am inferring from the increase in the value of bitcoins that an increase in demand for Y is occurring. There are possible other explanations.)
However, it should be noted that in order for the equation of exchange to be valid, the assumption of the velocity of money is relatively constant must hold. If holders of the coin stop using it as a currency for the exchange of value, then the M * V = M * 0 = 0. There is no price in that coin for any goods or services. That is, the value of the coin collapses.
Conversely, if the velocity of the coin were to increase significantly, then this creates effectively more available coin, resulting in the price (P) of the goods and services (Y) to increase. This causes price inflation, which encourages coin holders to spend their coin as fast as possible to avoid losing value in the coin. As the price of goods becomes excessive, people shift from the coin to other forms of currency. As this happens, once more a collapse happens.
At an equilibrium point, the coin supply is constant, the velocity is constant, the demand for goods and services is constant, and therefore the price would be constant. At such an equilibrium point, a constant coin supply would be ideal. However, we can observe throughout history that such an equilibrium point is never reached.
Given any sort of constant coin supply, the value of the coin is expected to vary unpredictably and often wildly. Of the 5 models, the first 4 will always be subject to this. Although this may be interesting for speculators, usefulness for general currency is questionable.
The fifth model is to manage the coin supply against an external asset value. In essence, this is a substitution of the coin for the asset. Provided that the coin supply can be managed to reflect the objective exchange rate, the value of the coin should be stable relative to the stability of the external asset value.
However, in my opinion, this marking of value does not take into account exchanges that are wholly internal to the coin and its blockchain. The transfer of a coin balance from one account to another implies an exchange of value, thus the equation of exchange applies internally to the blockchain. This exchange of value is independent of the exchange rate of the coin value versus the external asset value. Thus, the coin supply can be seen as independent of the exchange of value on the blockchain.
Given this assumption, we can make the simplifying assumption that the coin supply is relatively constant with respect to the exchange of value on the blockchain. As a result, one would expect that even though the coin supply is managed against the exchange rate with an external asset, its value can still fluctuate wildly, beyond the ability of coin supply management to compensate. This, in turn, will impact the exchange rate, destroying the intended objective.
As a natural consequence, even with the approach of marking the value of the coin to external asset value, such as the USD, the expected volatility limits the usefulness of the coin as a currency.

Towards A General Currency

As stated in the introduction, I believe that none of the cryptocurrency models described are viable for use as general currencies. In my opinion, my brief non-rigorous analysis above demonstrates this likely to be true. The question remains, what else is needed to create a cryptocurrency that is viable as a general currency.
The equation of exchange shows us what is missing directly: In the equation M * V = P * Y, we can say that on every blockchain we can know the values of M and V directly. The account ledger explicitly shows us this, (ignoring encrypted exchanges). What we do not know is the other side of the equation. We do not know either price (P) or goods and services (Y) for any exchanges that are internal to the blockchain, that is between accounts on the blockchain.
If we compare cryptocurrencies with national fiat currencies, and cryptocurrency exchanges with foreign exchanges, we can see that the foreign exchanges relate the difference in prices in related economies. In comparison, the cryptocurrency exchanges appear to only relate the difference in demand for the cryptocurrencies themselves. This demand only manifests itself during the exchange of cryptocurrencies for each other and between fiat and cryptocurrencies and vice-versa.
It is my position that because the internal use of cryptocurrencies on their own blockchains is currently hidden, none of the above coin supply models will create a currency stable enough to be useful as a general currency. If/when a cryptocurrency model is created that takes into account the currently hidden internal exchange of value, then we will have realized a general currency.

1 – Quote of the Week & Utopia Trivia

“Bitcoin is the currency of resistance.”
Utopia Trivia – What was the Genesis Block’s Reward Per Thread?
Look for the answers somewhere in this edition of TheMessage.

2 – A Deeper Look Inside The Rabbit Hole of Utopia – PART IV

In Part III we reviewed the meteoric rise and fall of Napster, followed by the birth of a truly Peer-to-Peer content sharing platform in the form of the BitTorrent protocol. We discussed how revolutionary a technology BitTorrent was and how integral to the Internet it has become. Now in Part IV, we will discuss what happens when the profoundly democratizing and resilient power of Peer-to-Peer technology is brought to bear on money itself.
On October 31st 2008, the Bitcoin white paper is published and on January 3 2009, Bitcoin’s Genesis Block is mined. Previously, the idea of digital money could not be realized in a direct, trustless fashion, because there always existed the problem of multiple spending. A trusted, third party database was always necessary and that handicap held back the potential of digital money for many years. Satoshi Nakamoto proposed an elegant solution; through cryptography, a Peer-to-Peer network could maintain the integrity of the record and allow participants to transfer value between each other without having to trust any third party. The simple but profound act of one human being directly handing another human being something of unique value was now finally enabled online through the internet. The social, economic and political implications of this technological breakthrough are still be felt to this day.
To understand how consequential a breakthrough Bitcoin was, you would need to appreciate how important a role money and its control plays in the lives of human beings. Most people today are born into societies where they have little choice in the matters of money. Decisions made by others many years ago affect their day to day lives in ways most do not understand. Human history is littered with examples of those in privileged positions abusing the power to create and regulate money to the detriment of the masses. Just as the power of communication and content sharing was placed in the hands of the people through Peer-to-Peer technology and the internet, now money itself was placed in the hands of the people through the P2P technology of Bitcoin. To participate in Bitcoin was itself a kind of defiant act against the existing power structures, a form of resistance–“Bitcoin is the currency of resistance.” Max Keiser, a broadcaster, film maker and Bitcoin proponent is quoted as saying.
The modern history of the internet has taught us that with every advancement and empowering step forward for humanity, vested corporate and government interests seek to extend their domain of influence by exerting power and control in lock-step with those advancements and Bitcoin is no exception. The only solution to diminish this negative influence, projected via surveillance and its coercive power, has been the equalizing power of cryptography and the democratizing power of P2P technology. What if advancements in these two fields could be brought to bear on a new kind of internet? An internet where surveillance and censorship were absent? An internet where communication, content and money could all flow in complete security and privacy? That will be the subject of Part V, our final segment in this series of articles; the revolution of Utopia.

3 – Mining Rewards Adjustment on Block #8843

Background
On the day of Utopia’s mainnet launch, November 18th 2019, the mining Reward Per Thread (and so the Genesis Block’s RPT) was set at 0.0128 CRP. It stayed set at a maximum of 0.0128 for approximately 3-4 weeks as the total thread count ballooned to over 30,000 and only marginally declined after 15,000 threads since the Total Reward Generated (TRG) was capped at 192 CRP per 15 minutes Block. It was because of the miner abuse associated with those initial weeks that a major update was released in mid-December mandating a bot be run on a system with a minimum specification of 4 CPUs and 4GB of RAM along with a Public IP. Once that new requirement was put in place, thread count collapsed from over 30,000 to less than 1,000. Within days, the team doubled the mining RPT to 0.0256 CRP in order to better incentivize users to operate bots on enhanced servers and support the network. Unfortunately version 1.0.5499 had serious issues with reward rate for miners and for 7 weeks users endured through inconsistent rewards until the much celebrated major update was finally released on Febraury 4th 2020. Major update version 1.0.5665 and minor update 5672 witnessed the thread count climb consistently from less than 1,000 threads to over 9,000 threads over the next 2 weeks. However, at 7,500 threads, when a number of users, this publisher included, expected to see a similar marginal decline in RPT as before, none was observed. The TRG number was apparently no longer capped at 192 as it previously had been, and the TRG saw its figure climb to as high as 230 CRP (equivalent to over 22,000 CRP per day) before the hammer came down.
Utopia Monetary Policy
At this point, it’s worth reviewing the 1984 Group’s purported monetary policy for Crypton and Utopia. In their own words:
“Multi-faceted and highly-professional approach to liquidity support and stable market rate of Crypton is well-organized with 3 main levers:
All of three adjustable settings listed above are currently controlled by Utopia development team but after implementation of decentralized referendum, self-governance and voting systems the full control of adjustable settings will be transferred to society.”
The Hammer of Block #8843, RPT vs TRG
On Block #8843 the team reduced the RPT from 0.0256 to 0.0096, a contraction of 62.5%, or a factor of 2.67. This happened on February 19th midday UTC time. According to a message sent by the team, “This measure is necessary for optimal total balance of mined Cryptons and for efficient CRP value support in current market conditions.”. Based on the team’s explanation, they did this in order to control the trajectory of total CRP in circulation (“optimal total balance of mined Cryptons”) as well as to provide support to the value of CRP in the market, (“efficient CRP value support in current market conditions”). Why they chose to exercise control at the RPT level rather than the TRG level is the most fascinating question to consider. Capping the TRG has the additional effect of marginally disincentivizing new threads, whereas reducing the RPT doesn’t have that negative marginal effect, it simply makes each thread less productive. While both would have a similar monetary or economic net effect, they provide different incentives to miners. By reducing RPT, miners are incentivized to find more cost-effective servers in the long run, while the addition of new threads continues to be incentivized in a similar fashion. Therefore, we can conclude that the team wants to see the thread count continue to multiply, but did not want to compromise the inflation of CRP to accomplish this. Furthermore, because the reward rate of mining bots is already relatively high, it can be concluded that the RPT is unlikely to ever see an increase again.

4 – Updated CRP Price Structure at TheMarket

With the cost of mining CRP having increased by a factor of 2.67, TheMerchant is updating the price structure at TheMarket in order to better accommodate potential investors with different price sensitivities.
The Normal high-volume selling price will now be $2.50/CRP. This will be the default price around the clock when not in the 14:00 to 22:00 UTC time slot on Saturdays.
The Once-Per-Week high volume selling price will now be $2.00/CRP. This will be every Saturday except the final Saturday of the month, from 14:00 UTC to 22:00 UTC. (February 22, March 7, 14, 21, etc.)
The Once-Per-Month high volume selling price will now be $1.50/CRP. This will be on the final Saturday of the month, from 14:00 UTC to 22:00 UTC. February 29, March 28, April 25 etc.)
The reason for this price structure is that until a low-friction, high-volume exchange is established, there needs to be a reliable and predictable way to meet the needs of potential investors at different price points. Some investors have a long enough investment horizon that buying at $2.50 or $2.00 or $1.50 is not as important as being able to accumulate as much CRP as possible from a trusted source before the supply is exhausted. This investor would be considered more time-sensitive and less price-sensitive and more likely to acquire TheMerchant’s supply before others. Whereas other investors may have a shorter investment horizon and patiently waiting until the end of the week on Saturday, or quite possibly even until the end of the month on the final Saturday is more appealing to them, even at the risk of the supply having been reduced to completely exhausted, because they are more price-sensitive. In all cases, buy orders will be prioritized on a first-come, first-served basis.

Brief History Of Bitcoin

Brief History Of Bitcoin
From the earliest starting point, it was a riddle. In 2008, somebody utilizing the moniker Satoshi Nakamoto distributed a paper to a cryptography mailing list. It was called Bitcoin: A Peer-to-Peer Electronic Cash System.

Much to anyone's dismay that, at its tallness, it would build up a whole market (the crypto showcase) esteemed at $800B. That is more cash than Coca Cola, McDonald's, Ford, Caterpillar, Nike, Nintendo, and Goldman Sachs consolidated. What's more, presently, with that enormous fortune behind it, some think this single PDF can possibly overturn the whole worldwide financial industry.

On one side of this fight is a gathering of obscure cyrptographers competing to cut down business as usual. On the opposite side is the United States government, the European Union, JPMorgan Chase, and Deutsche Bank.

Money making governments over the globe, if truly tested, will persevere relentlessly to keep control of their financial frameworks. They'll likely locate an all around financed partner in the 50-trillion-dollar banking industry. The War on Money may be the most basic war of the cutting edge period in light of the fact that the victor will choose the destiny of creating economies, tax collection, expansion, fear based oppression, and — quite possibly — democracy itself.

You'd think with that much in question, the creator of this infamous paper would step into the spotlight. During Bitcoin's fleeting ascent, as the maker's close to home riches outperformed one billion dollars, you'd envision someone would reveal him. What's more, when his riches arrived at an expected $19.4B, you'd accept the IRS would come thumping.

In any case, no one has even had the option to find the baffling Nakamoto. What's more, that is part Bitcoin's allure. For the individuals who don't have the foggiest idea, Bitcoin resembles an advanced dollar. In 2009, it was worth short of what one-tenth of one penny, and in 2017, it was worth $20,000. Inside a couple of days, it tends to be worth half or twice to such an extent. Its worth vacillates quickly. That is one of its issues. Yet, the best part about Bitcoin is the one thing that doesn't change. On the off chance that you recognize what you're doing, it's difficult to find. It's generally unknown.

It's the unknown piece that is pulled in light of a legitimate concern for everyone from tax criminals to medicate dealers to fraudsters. By its very nature, Bitcoin is difficult to control. What's more, something that is difficult to control makes it simple to swindle a great deal of laws to make a huge amount of cash.

https://preview.redd.it/v69utlsazeh41.jpg?width=275&format=pjpg&auto=webp&s=f9a5cd1dedd298856bf5219feb8141ccb44ab41e
On the off chance that you would've purchased $10 worth of Bitcoin in 2009, you'd be perched on a cool $200M at the present time. That is the sort of news feature the normal individual focuses on. So news systems began announcing it. Your companions began getting it. What's more, it appeared anyone who put a couple of bucks into Bitcoin was getting the money for out with basins of gold. So the franticness started, in 2017, when Bitcoin went from a play-toy of technologists and an empowering influence of sorted out wrongdoing to a typical speculation held by pretty much everybody's grandmother.

I'm not here to disclose to you that Bitcoin is an air pocket, since I am not even close to able to demonstrate that. Specialists are as yet discussing if Bitcoin is a ware, a security, a store of significant worth, a cash, or some out and out new resource class completely. Due to this I won't start to evaluate the genuine estimation of Bitcoin. I'm not by any means sure it bodes well to. What's more, on the off chance that I by one way or another could, in the event that I had some mystery, insightful capacity to know where the cost of Bitcoin was going, I'd contribute, not composing this article.

What I am here to do is: inform you regarding the con artists. Since they're all over the place. It's explicitly self-evident. Furthermore, on the off chance that you are very brave, or you're considering getting a few (or some other Cryptocurrency), you better know exactly how awful the con artists are. Since when you're the least educated individual on the trade, you get counted on.

How profound does the Rabbit-Hole Gox?

On January 3, 2009, Satoshi Nakamoto set up the Genesis square. That is an extravagant method for saying he "mined" the first Bitcoin.

He didn't go out to some collapse Madagascar with a pickax and return with a sparkling, valuable metal. He ran a hashing calculation on his PC for some time and put away the outcomes in a record. We consider that record the "blockchain". It's open data. The explanation it's open is with the goal that it's circulated. The explanation it's dispersed is on the grounds that, dissimilar to with US Dollars, in the event that you jump on some administration authority's awful side, there's for all intents and purposes no danger of your benefits being solidified (or taken).

The blockchain is a really progressive innovation. Also, after the secretive Nakamoto discharges the Genesis square to the general population, crypto lovers pay heed. Some of them start "mining" Bitcoin. Some of them do it because of the decency of their souls. In any case, a great deal of them are presumably determined by the prize that gives "mining" its name. At the point when you run this hashing calculation on squares of exchanges and store the outcomes to the open record, you're remunerated with Bitcoin. At its pinnacle, this prize could add up to in excess of 250,000 US Dollars.

What are Bitcoin and Other Cryptocurrencies Backed By?

Bitcoin was created back in 2009 and became the first cryptocurrency ever designed. Cryptocurrencies have become increasingly popular in the last few years as they offer an efficient and decentralized way of transferring money.
Cryptocurrencies have always been an alternative to banks and fiat money. But why do they have any value at all and who dictates what they are worth? The value of Bitcoin is really calculated through supply and demand. The digital asset itself is backed by nothing more than perhaps the blockchain ledger.
Every single cryptocurrency uses a blockchain ledger, a system that records transactions between two or more parties in a verifiable and permanent way. This certainly adds value to Bitcoin and cryptocurrencies. However, it is not what determines their price.
Why Things Have Value
Why does anything have any value at all? It has mostly because of supply and demand. Traditional currencies, for instance, are only backed by the government that issued them. Digital money, like Bitcoin, is not backed or linked to any physical reserves like gold and can certainly lose value due to different factors.
Cryptocurrencies have value because they require ‘work’ to exist. Cryptocurrencies are maintained thanks to the mining process, a process in which transactions are verified by different people. This process requires a certain amount of work, electricity, and money.
Key Factors That Affect The Value of Cryptocurrencies
Since most cryptocurrencies are not physically backed by anything, their value is determined through supply and demand based on a few important factors. One of the biggest advantages of cryptocurrencies is scarcity. The supply of most cryptocurrencies is fixed, and, unlike traditional currencies, no one can issue more than the maximum limit. This means that cryptocurrencies are deflationary by nature.
Another key factor that benefits cryptocurrencies is divisibility. Any cryptocurrency can be divided into smaller units. A simple change in Bitcoin’s code could allow the digital asset to be divided into infinitely smaller units at any time.
Additionally, transferring cryptocurrencies can be extremely fast and cheap compared to traditional methods. Fees are somewhat fixed no matter the amount you send, which means that theoretically you could send 1 million Bitcoins to someone and pay only a few dollars in fees (or even less).
In a way, one could say that Bitcoin and cryptocurrencies are backed by the public’s faith in them as they have realized that the current monetary system is not as robust as one might think.
Why Are Cryptocurrencies so Volatile Then?
In comparison to traditional currencies and even stocks, cryptocurrencies are far more volatile, meaning that the current price of any given crypto can change drastically in hours. It’s quite common to see Bitcoin’s price go up or down 5-10% within a few days. In fact, even in periods of low volatility, most cryptocurrencies still experience price moves of up to 1-2%, which is considered extremely high in traditional markets.
The explanation, however, is quite simple. Cryptocurrencies, in general, lack the liquidity that the rest of the markets enjoy. According to statistics from Statista, the average daily turnover in the global foreign exchange market was around $6.5 trillion daily. The cryptocurrency market, on average, sees around $80 billion in daily trading volume, and according to various sources, a lot of the volume is actually fake.
The problem with illiquidity is that someone who wants to sell or buy a huge amount of Bitcoin or any cryptocurrency will simply ‘eat’ all the orders in the order book of the exchange, catapulting the price up or crashing it. That is the only reason why cryptocurrencies, in general, are extremely volatile.
Some Cryptocurrencies Are Actually Backed by Things
There are, however, some cryptocurrencies that are backed by gold, assets, and even fiat money. Tether (USDT) became the most popular cryptocurrency backed by fiat, later known as a ‘stablecoin’.
Stablecoins
A stablecoin is designed to always be worth $1.00 by maintaining 1 dollar in some sort of reserve. The first stablecoin to become widely popular was Tether, however, there was a lot of controversy surrounding it. Most of the criticism came from the fact that Tether Limited was unable to prove they actually have the funds to cover all the Tether issued.
Additionally, on 30 April 2019, Tether Limited’s lawyer actually admitted that each coin is only backed by $0.74 in cash.
Currently, there are over a dozen stablecoins that are backed by fiat, commodities, and even cryptocurrencies. TrueUSD is similar to Tether but it is considered to be one of the most reliable stablecoins currently as the company behind it has been extremely transparent and conducted an independent audit back in March 2019.
A more complex stablecoin is Dai, which is backed by Ethereum and pegged to the dollar. The system behind Dai basically locks Ethereum in a public contract. If the value of Dai distances too far from $1, the system will make use of the contract to stabilize it back. There is, however, a small problem: Dai is not entirely decentralized as the technology behind it is being monitored by the Maker Foundation.
DigixDAO is another stablecoin and it’s backed by bars of actual gold. It is an ERC-20 token created back in 2014. The digital asset is entirely decentralized and autonomous and can in fact be extended to be backed by other precious metals and even physical assets. According to the company, the gold is stored in custodial vaults at the Singapore Safe House, and 1 DGX will always equal 1 gram of gold.
Cryptocurrencies Backed by Assets
Not all cryptocurrencies backed by assets are stablecoins. For instance, the first oil-backed cryptocurrency was introduced by Venezuelan President Nicolas Maduro back in 2017. El Petro, although highly criticized, is supposedly the first cryptocurrency to be backed by oil thanks to the country’s huge oil and mineral reserves.
Petro is, however, not pegged to anything, and its value can increase or decrease at any given time.
Tokenization of Assets
Something that has become quite popular over the last few years is the tokenization of traditional stocks and assets. There are countless blockchain startups tokenizing almost anything to represent ownership.
The tokenization of assets brings numerous benefits like greater liquidity, more transparency, cheaper and faster transactions, and more accessibility. Tokenization itself is quite difficult to regulate, and all tokenization assets have to be compliant with the law, something that issuers struggle to achieve.
Conclusion
While traditional cryptocurrencies are not necessarily backed by anything physical, they still hold a lot of value solely based on supply and demand. This is the case with numerous other assets and even fiat money.
Cryptocurrencies have come a long way and there is a wide variety of them. Stablecoins are the most popular when it comes to asset-backed cryptocurrencies. They serve as an alternative to fiat money and bring a lot of liquidity to the market. There are definitely concerns as people question their stability, however, they have become an important factor in the market.
Additionally, other projects aside from stablecoins have implemented asset-backed cryptocurrencies. There are numerous cryptocurrencies out there backed by precious metals, physical assets, stocks, and even other cryptocurrencies. We are definitely going to see even more in the near future as they bring a lot more security to investors and the crypto space in general.

Bitcoin blockchain records mining difficulty record Simple BitCoin Explanation for all ages - YouTube How to Mine Bitcoins Using Your Own Computer Bitcoin Halving 2020: History & Price Prediction (A Simple Explanation) How to get started on Bitcoin!!

Bitcoin mining is the backbone of the Bitcoin network. Miners provide security and confirm Bitcoin transactions. Without Bitcoin miners, the network would be attacked and dysfunctional. Bitcoin mining is the process by which transactions are verified and added to the public ledger, known as the block chain, and also the means through which new bitcoin are released. Anyone with With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine. Bitcoin is Secure. Bitcoin miners help keep the Bitcoin network secure by approving transactions. Bitcoin mining serves two purposes. First, it’s the process by which Bitcoin transactions are processed. Every Bitcoin transaction that takes place is included in a block, and thousands of miners compete to have the privilege of validating those blocks. Mining is also the process by which new Bitcoin is created and added to Bitcoin’s supply. Bitcoin: Definition, History, Statistic, Technical Explanation & Interesting Facts.
