⚡ Lightning FAQs ⚡

If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily,
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source

How are paths found in Lightning Network?
Bitcoin Stack Exchange Answer
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Stack Exchange Answer
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
No -- Source
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
Stack Exchange Answer
Can the Lightning Network work on any other cryptocurrency? How?
Stack Exchange Answer
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?
Stack Exchange Answer

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.

PSA Warning! Global MLM OneCoin / OneLife scheme in WA

Hey Seattle and WA redditors. While is comical, this post is meant to warn others of this global MLM company attempting to scam local citizens. This is a long post because of the subjects complexity. If your enjoying a gorgeous day that's precious to this season. Bookmark and come back :)
TLDR: OneCoine/Onelife is a global MLM scam using deceptive practices and has already been reported by other countries. FREE EDUCATION ON BITCOIN AND BLOCKCHAIN AT THE BOTTOM.
User black_ish reported in Bitcoin about his family investing in OneCoin and being locked into it for $100k. I've also found a Craigslist post for OneCoin in Seattle. Before this scheme claims more around my area. I'll help describe it and at the same time try educate others on cryptocurrency/digital currency, and blockchains.
You might have heard of a growing technology called Bitcoin and its blockchain features or you might be introduced to it soon. You might already know someone that does mine it or works with. I personally mine Bitcoin and Ethereum. I've found over the years Washington is home to not only large digital currency mining operations but also businesses in the ecosystem forming around it. Such as KeepKey that is based in Kirkland, they make Bitcoin wallets. If your at the UW campus you can find a Bitcoin ATM in the startup hall. Microsoft accepts it as a payment option and has made a partnership with Ethereum to explore its distributed ledger technology that differs from Bitcoin.
This is to illustrate how open-source blockchain ledgers have been embrassed in such a short amount of time. Bitcoin's success and failings is being utilized to hype many fraudulant operations and projects as well. The biggest one still around is OneCoin/Onelife. Mainly due to them restricting withdraws from the system and obscuring the source code of OneCoin's blockchain.
The OneCoin & OneLife scheme.
OneCoin was started by Ruja Ignatova in Bulgaria. The main business of Onecoin Ltd. is to sell "education" material for trading and cryptocurrency. That's loosely quoted because they've been caught plagarising published sources and branding it under them in their training packages. With each educational package they sell you, you get OneCoin tokens to be assigned to "mine". The "mining OneCoin" videos I've found like this 'Submit Tokens to Start Mining OneCoin after a split and 'How do I mine OneCoin' indicate to me it isn't mining the same way Bitcoin does. Bitcoin mines through a Proof-of-work and the outputs you get from ming are different from regular outputs with open coirse coins. OneCoin looks to be doing Proof-of-stake mining, the more coins you have the more you make over time by staking (locking them into the network) to get a higher return later on. This distinction in protocol is never mentioned but marketed as a superior blockchain to Bitcoins.
Speaking of OneCoin's blockchain it doesn't make a lot of sense. Videos on OneCoin's blockchain with numbers in it, gives odd outputs compared to the first POS coin, Peercoin. Additionally the section that is stating "CURRENT BLOCK IS MINING FROM" is a cycle of repeating hexidecimal code in the background. It is technical jibberish meant to fake the actual technical process of real mining.
I wanted to go over the technical details of this scheme first because it aims to confuse people into believing that there is a value in this OneCoin blockchain, more specifically Dr. Ruja Ignova's coin. The reason why its rolling through the United States and your hearing about it more is because of the recent announcement of "retiring this blockchain" and starting a new blockchain in October of this year. Yes economic majors you heard that correctly. Dr. Ruja Ignatova is promising to double all OneCoin's on the October reboot of OneCoin, regardless of the account. Those package names and prices should also be alarming to most.
OneCoin & OneLife around the globe.
How OneCoin grew is with big, theatrical events, always hyping the OneCoin's blockchain and showing people a private exchange, xcoinx, that shows OneCoin as a tradable coin second to Bitcoin. The exchange isn't open, since 2015, to anyone. It is used to make an artificial claim that it is a global competitor coin. Here is an actual market cap site showing the real top 10 currently traded coins, coinmarketcap.com. OneCoin cannot be traded on any exchange. A basic rule most of the exchanges abide by is the coin has to be open-source to be traded. Each exchange has different standards but open-source is a constant between them all.
Your welcome to find the long OneCoin/Onelife event videos held in Dubai and China. They showcase how they utilize high productive tricks to facilitate real facts about the packages and blockchain that I've gone over.
Another way OneCoin's membership grew is repackaging the blockchain or private payment system. Hence the reason why I'm warning about the rebrand through the US. In Zhongshan, China a group attempted to bring members to their OneCoin hierachy through calling it "Vicat Credits". If you cannot translate the page from your browser or cannot read. The fifth picture in the article shows the OneCoin brand usage.

Message to Dr Ruja Ignatoca Onecoin from X Onecoin Top Leader & host Imi Shah. This video is about a OneCoin promoter being locked out of his account and froze id's with no reason given. It illustrates the point the OneCoin system can shutoff your account without recourse.
Deceptive youtube titles attempting to associate successful people to the OneCoin brand.
BillGates clickbate - 1 and Billgates clickbate - 2. Both videos use the same video footage from an actual interview with Bill Gates being excited with blockchain technology. Hello Mr.Gates - thisisbillgates or whomever monitors the account. I'm sure the video footage was not referring to OneCoin's privatized blockchain.
Richard Branson clickbate. Hello Mr. Branson - TheRichardBranson or whomever monitors the account. I'm pretty sure Mr Branson wasn't implying that OneCoin was going to replace Bitcoin.
Both Mr. Gates and Mr. Branson likeness can be found in a recent video as well. OneCoin Latest Presentation July 2016 Best Explanation Full Update during the 11min mark. The next slide where you see Dr. Ruja Ignatova on the cover of Forbes is already controversial, didn't happen, and your welcome to search for it.
These are examples of how OneCoin members and promoters attempt to decieve the public.
Congratulations making it this far. Now comes the good part on how we can help each other.
If you know of any free legal sources to consult with users like black_ish please post them! There are probably others that need the links as well. The details on what's been experienced and how money in being locked into this MLM sounds very wrong. The promoters usually open a LLC around the area they plan to promote in.
!!Free Blockchain education!!
Since OneCoin/Onelife/OneAcademy is pretending educate others at a very high cost. I think the best idea is to educate others and let them decide what coin or blockchain they want to particpate on.

explicacion del video anterior: [SPOILER]Todo lo hace en la testchain de Bitcoin. Abre un canal con 0'04 testcoins y efectua el pago de 10000 milisatoshis para comprar la ya famosa imagen de los gatitos viendo la luna.
No hay transacción de vuelta, es símplemente un pago que se ha realizado a través del canal que habían abierto.
En la blockchain (en realidad, en la testchain, puesto que se está utilizando la cadena de bloques para pruebas que tiene Bitcoin) se ha realizado una transacción, que es la transacción necesaria que hay que hacer para establecer el canal.
La transacción de compra de la imagen (la de los 10000 milisatoshis) es la que se hace fuera de la cadena de bloques.
A ver, el canal se establece por un importe de 0'04 bitcoins (testcoins, en realidad). Una vez realizada la transacción de 10000 milibitcoins en la lightning network, el balance de ese canal cambia a 0'04 bitcoins - 10000 milibitcoins.
Pero lo bueno del asunto es que el canal de pagos es bidireccional y, se supone, que formará parte de una red (la lightning network) de manera que el balance se irá reajustando conforme las transacciones de la red vayan necesitando hacer uso de dicho del canal de pago que has abierto.
Cuando cualquiera de las dos partes decida cerrar el canal, entonces el balance que contenga en ese instante será el que se fijará en la cadena de bloques.
Las transacciones que emplean el canal de pago son "off blockchain", esto es, se realizan sin necesidad de ser reflejadas en la cadena de bloques. La única transacción que ha necesitado utilizar la cadena de bloques es la necesaria para crear el canal.
El canal no se ha cerrado, ha permanecido abierto.[/SPOILER] P.D 3:

PSA Warning! Global MLM OneCoin / OneLife scheme in WA : /u/PM_ME_UR_CRYPT0

Hey Seattle and WA redditors. While is comical, this post is meant to warn others of this global MLM company attempting to scam local citizens. This is a long post because of the subjects complexity. If your enjoying a gorgeous day that's precious to this season. Bookmark and come back :)
TLDR: OneCoine/Onelife is a global MLM scam using deceptive practices and has already been reported by other countries. FREE EDUCATION ON BITCOIN AND BLOCKCHAIN AT THE BOTTOM.
User black_ish reported in Bitcoin about his family investing in OneCoin and being locked into it for $100k. I've also found a Craigslist post for OneCoin in Seattle. Before this scheme claims more around my area. I'll help describe it and at the same time try educate others on cryptocurrency/digital currency, and blockchains.
You might have heard of a growing technology called Bitcoin and its blockchain features or you might be introduced to it soon. You might already know someone that does mine it or works with. I personally mine Bitcoin and Ethereum. I've found over the years Washington is home to not only large digital currency mining operations but also businesses in the ecosystem forming around it. Such as KeepKey that is based in Kirkland, they make Bitcoin wallets. If your at the UW campus you can find a Bitcoin ATM in the startup hall. Microsoft accepts it as a payment option and has made a partnership with Ethereum to explore its distributed ledger technology that differs from Bitcoin.
This is to illustrate how open-source blockchain ledgers have been embrassed in such a short amount of time. Bitcoin's success and failings is being utilized to hype many fraudulant operations and projects as well. The biggest one still around is OneCoin/Onelife. Mainly due to them restricting withdraws from the system and obscuring the source code of OneCoin's blockchain.
The OneCoin & OneLife scheme.
OneCoin was started by Ruja Ignatova in Bulgaria. The main business of Onecoin Ltd. is to sell "education" material for trading and cryptocurrency. That's loosely quoted because they've been caught plagarising published sources and branding it under them in their training packages. With each educational package they sell you, you get OneCoin tokens to be assigned to "mine". The "mining OneCoin" videos I've found like this 'Submit Tokens to Start Mining OneCoin after a split and 'How do I mine OneCoin' indicate to me it isn't mining the same way Bitcoin does. Bitcoin mines through a Proof-of-work and the outputs you get from ming are different from regular outputs with open coirse coins. OneCoin looks to be doing Proof-of-stake mining, the more coins you have the more you make over time by staking (locking them into the network) to get a higher return later on. This distinction in protocol is never mentioned but marketed as a superior blockchain to Bitcoins.
Speaking of OneCoin's blockchain it doesn't make a lot of sense. Videos on OneCoin's blockchain with numbers in it, gives odd outputs compared to the first POS coin, Peercoin. Additionally the section that is stating "CURRENT BLOCK IS MINING FROM" is a cycle of repeating hexidecimal code in the background. It is technical jibberish meant to fake the actual technical process of real mining.
I wanted to go over the technical details of this scheme first because it aims to confuse people into believing that there is a value in this OneCoin blockchain, more specifically Dr. Ruja Ignova's coin. The reason why its rolling through the United States and your hearing about it more is because of the recent announcement of "retiring this blockchain" and starting a new blockchain in October of this year](https://www.youtube.com/watch?v=0KTzE-sJ2Tk). Yes economic majors you heard that correctly. Dr. Ruja Ignatova is promising to double all OneCoin's on the October reboot of OneCoin, regardless of the account. Those package names and prices should also be alarming to most.
OneCoin & OneLife around the globe.
How OneCoin grew is with big, theatrical events, always hyping the OneCoin's blockchain and showing people a private exchange, xcoinx, that shows OneCoin as a tradable coin second to Bitcoin. The exchange isn't open, since 2015, to anyone. It is used to make an artificial claim that it is a global competitor coin. Here is an actual market cap site showing the real top 10 currently traded coins, coinmarketcap.com. OneCoin cannot be traded on any exchange. A basic rule most of the exchanges abide by is the coin has to be open-source to be traded. Each exchange has different standards but open-source is a constant between them all.
Your welcome to find the long OneCoin/Onelife event videos held in Dubai and China. They showcase how they utilize high productive tricks to facilitate real facts about the packages and blockchain that I've gone over.
Another way OneCoin's membership grew is repackaging the blockchain or private payment system. Hence the reason why I'm warning about the rebrand through the US. In Zhongshan, China a group attempted to bring members to their OneCoin hierachy through calling it "Vicat Credits". If you cannot translate the page from your browser or cannot read. The fifth picture in the article shows the OneCoin brand usage.
Bulgarian FSC issues OneCoin Warning on 30 September 2015.
The Direct Selling Association in Norway wanrined against OneCoin as well.
Other sources of exposure.

Beware of Definitive OneCoin Ponzi. Thanks TimTayshun for the link to the OneCoin "education" slides and this link.
OneCoin suspend Mastercard approvals & withdrawls from the failed Mastercard partnership. Members were also arrested.
Message to Dr Ruja Ignatoca Onecoin from X Onecoin Top Leader & host Imi Shah. This video is about a OneCoin promoter being locked out of his account and froze id's with no reason given. It illustrates the point the OneCoin system can shutoff your account without recourse.
Deceptive youtube titles attempting to associate successful people to the OneCoin brand.
BillGates clickbate - 1 and Billgates clickbate - 2. Both videos use the same video footage from an actual interview with Bill Gates being excited with blockchain technology. Hello Mr.Gates - thisisbillgates or whomever monitors the account. I'm sure the video footage was not referring to OneCoin's privatized blockchain.
Richard Branson clickbate. Hello Mr. Branson - TheRichardBranson or whomever monitors the account. I'm pretty sure Mr Branson wasn't implying that OneCoin was going to replace Bitcoin.
Both Mr. Gates and Mr. Branson likeness can be found in a recent video as well. OneCoin Latest Presentation July 2016 Best Explanation Full Update during the 11min mark. The next slide where you see Dr. Ruja Ignatova on the cover of Forbes is already controversial, didn't happen, and your welcome to search for it.
These are examples of how OneCoin members and promoters attempt to decieve the public.
Congratulations making it this far. Now comes the good part on how we can help each other.
If you know of any free legal sources to consult with users like black_ish please post them! There are probably others that need the links as well. The details on what's been experienced and how money in being locked into this MLM sounds very wrong. The promoters usually open a LLC around the area they plan to promote in.
!!Free Blockchain education!!
Since OneCoin/Onelife/OneAcademy is pretending educate others at a very high cost. I think the best idea is to educate others and let them decide what coin or blockchain they want to particpate on.
