how to start mining with FPGA - Bitcoin Stack Exchange

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!!!

GPU Mining Crash Course - START HERE!

Welcome All to the GPUMining Crash Course!
With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.

What is cryptocurrency mining?

One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is...
You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.

What kind of rig should I build?

You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs.
For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each)
There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD.
Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:

She's built, now what?

Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
  1. Update Windows - Do all of the updates. Just do it.
  2. Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
  3. Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.

Mining Software

There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on.
Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit.
Other Windows mining softwares include:
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.

I keep hearing about NiceHash. What is that?

The asshole of the mining industry. Jk, but not really.
NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin.
They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be.
NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform.
For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.

Concluding Thoughts

This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them.
If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

Why is getting into FPGA's such a crappy experience?

I'm a hobbyist and this is my first venture into FPGA's. I understand how FPGA works in theory. It's just a bunch of combinational logic connected by clock-connected flip-flops, whose topology and combinational functions can be programmed with a high level language. I bought a Xilinx board from embeddedmicro.com and I'm going to work through their tutorials.
All I want to be able to do is specify a bunch of like registers and crap, and how to connect them with clocked flip-flops to do some really basic stuff like a simple CPU with 1-2 custom instructions or something. So why do I have to download a GIANT SIX GIGABYTE FILE TO DO THAT? What could this software possibly be doing that it needs to be that big?
In a sane world, all I'd need is a board and a simple compiler which just takes the high-level language and turns it into the topology file to upload to the board. But in the insanity in which I am currently living, I have to download some gigantic IDE that is going to be huge and probably slower than mining bitcoins on an NES. I don't know because IT'S STILL DOWNLOADING.
So to even get to the download, I had to log into the website, register, and give them a name and a physical address (and God forbid I should leave the "Company" field empty!). The Licensing crap on their website looks like you need an MBA to understand it. This company sells pieces of hardware, FFS! Why in Stallman's name can't they just make the software FOSS and let anyone download it instead of all this BS about WEBPACK this and annual upgrade that?
Xilinx, in case you haven't noticed, in order for anyone to actually use your software, THEY HAVE TO BUY A CHIP OR BOARD AND YOU CAN MAKE MONEY OFF YOUR CUSTOMERS THAT WAY. CHARGING FOR SOFTWARE OR HAVING A BYZANTINE PROCESS FOR GETTING A FREE LICENSE MAKES ZERO SENSE FOR A HARDWARE COMPANY.
Anyone know a place where you can just buy an FPGA board, plug it into a USB port, sudo apt-get install some FOSS compiler, type your Verilog or VHDL or whatever into emacs, run 2-5 commands and have a running design?
If such a place doesn't exist, some startup needs to disrupt this industry. If you make it easy for people to develop for your HW, those devs will be inclined buy your product just to make their lives easier.

QuarkChain Testnet 2.0 Mining.

QuarkChain Testnet 1.0 was built based on standardized blockchain system requirements, which included network, wallet, browser, and virtual machine functionalities. Other than the fact that the token was a test currency, the environment was completely compatible with the main network. By enhancing the communication efficiency and security of the network, Testnet 2.0 further improves the openness of the network. In addition, Testnet 2.0 will allow community members (other than citizens or residents of the United States) to contribute directly to the network, i.e. running a full node and mining, and receive testnet tokens as rewards.
QuarkChain Testnet 2.0 will support multiple mining algorithms, including two typical algorithms: Ethash and Double SHA256, as well as QuarkChain’s unique algorithm called Qkchash – a customized ASIC-resistant, CPU mining algorithm, exclusively developed by QuarkChain. Mining is available both on the root chain and on shards due to QuarkChain’s two-layered blockchain structure. Miners can flexibly choose to mine on the root chain with higher computing power requirements or on shards based on their own computing power levels. Our Goal By allowing community members to participate in mining on Testnet 2.0, our goal is to enhance QuarkChain’s community consensus, encourage community members to participate in testing and building the QuarkChain network, and gain first-hand experience of QuarkChain’s high flexibility and usability. During this time, we hope that the community can develop a better understanding about our mining algorithms, sharding technologies, and governance structures, etc. Furthermore, this will be a more thorough challenge to QuarkChain’s design before the launch of mainnet! Thus, we sincerely invite you to join the Testnet 2.0 mining event and build QuarkChain’s infrastructure together!
Today, we’re pleased to announce that we are officially providing the CPU mining demo to the public (other than citizens and residents of the United States)! Everyone can participate in our mining event, and earn tQKC, which can be exchanged to real rewards by non-U.S. persons after the launch of our mainnet. Also, we expect to upgrade our testnet over time, and expect to allow GPU mining for Ethash, and ASIC mining for Double SHA256 in the future. In addition, in the near future, a mining pool that is compatible with all mining algorithms of QuarkChain is also expected to be supported.
We hope all the community members can join in with us, and work together to complete this milestone! 2 Introduction to Mining Algorithms 2.1 What is mining? Mining is the process of generating the new blocks, in which the records of current transactions are added to the record of past transactions. Miners use software that contribute their mining power to participate in the maintenance of a blockchain. In return, they obtain a certain amount of QKC per block, which is called coinbase reward. Like many other blockchain technologies, QuarkChain adopts the most widely used Proof of Work (PoW) consensus algorithm to secure the network.
A cryptographically-secure PoW is a costly and time-consuming process which is difficult to solve due to computation-intensity or memory intensity but easy for others to verify. For a block to be valid it must satisfy certain requirements and hash to a value less than the current target threshold. Reverting a block requires recreating all successor blocks and redoing the work they contain, which is costly.
By running a cluster, everyone can become a miner and participate in the mining process. The mining rewards are proportional to the number of blocks mined by each individual.
2.2 Introduction to QuarkChain Algorithms and Mining setup According to QuarkChain’s two-layered blockchain structure and Boson consensus, different shards can apply different consensus and mining algorithms. As part of the Boson consensus, each shard can adjust the difficulty dynamically to increase or decrease the hash power of each shard chain.
In order to fully test QuarkChain testnet 2.0, we adopt three different types of mining algorithms” Ethash, Double SHA256, and Qkchash, which is ASIC resistant and exclusively developed by QuarkChain founder Qi Zhou. These first two hash algorithms correspond to the mining algorithms dominantly conducted on the graphics processing unit (GPU) and application-specific integrated circuits (ASIC), respectively.
I. Ethash Ethash is the PoW mining algorithm for Ethereum. It is the latest version of earlier Dagger-Hashimoto. Ethash is memory intensive, which makes it require large amounts of memory space in the process of mining. The efficiency of mining is basically independent of the CPU, but directly related to memory size and bandwidth. Therefore, by design, building Ethash ASIC is relatively difficult. Currently, the Ethash mining is dominantly conducted on the GPU machines. Read more about Ethash: https://github.com/ethereum/wiki/wiki/Ethash
II. Double SHA256 Double SHA256 is the PoW mining algorithms for Bitcoin. It is computational intensive hash algorithm, which uses two SHA256 iterations for the block header. If the hash result is less than the specific target, the mining is successful. ASIC machine has been developed by Bitmain to find more hashes with less electrical power usage. Read more about Double SHA256: https://en.bitcoin.it/wiki/Block_hashing_algorithm
III. Qkchash Originally, Bitcoin mining was conducted on the CPU of individual computers, with more cores and greater speed resulting in more profitability. After that, the mining process became dominated by GPU machines, then field-programmable gate arrays (FPGA) and finally ASIC, in a race to achieve more hash rates with less electrical power usage. Due to this arms race, it has become increasingly harder for prospective new miners to join. This raises centralization concerns because the manufacturers of the high-performance ASIC are concentrated in a small few.
To solve this, after extensive research and development, QuarkChain founder Dr. Qi Zhou has developed mining algorithm — Qkchash, that is expected to be ASIC-resistant. The idea is motivated by the famous date structure orders-statistic tree. Based on this data structure, Qkchash requires to perform multiple search, insert, and delete operations in the tree, which tries to break the ASIC pipeline and makes the code execution path to be data-dependent and unpredictable besides random memory-access patterns. Thus, the mining efficiency is closely related to the CPU, which ensures the security of Boston consensus and encourges the mining decentralization.
Please refer to Dr. Qi’s paper for more details: https://medium.com/quarkchain-official/order-statistics-based-hash-algorithm-e40f108563c4
2.3 Testnet 2.0 mining configuration Numbers of Shards: 8 Cluster: According to the real-time online mining node The corresponding mining algorithm is Read more about Ethash with Guardian: https://github.com/QuarkChain/pyquarkchain/wiki/Ethash-with-Guardian)
We will provide cluster software and the demo implementation of CPU mining to the public. Miners are able to arbitrarily select one shard or multiple shards to mine according to the mining difficulty and rewards of different shards. GPU / ASIC mining is allowed if the public manages to get it working with the current testnet. With the upgrade of our testnet, we will further provide the corresponding GPU / ASIC software.
QuarkChain’s two-layered blockchain structure, new P2P mode, and Boson consensus algorithm are expected tobe fully tested and verified in the QuarkChain testnet 2.0. 3 Mining Guidance In order to encourage all community members to participate in QuarkChain Testnet 2.0 mining event, we have prepared three mining guidances for community members of different backgrounds.
Today we are releasing the Docker Mining Tutorial first. This tutorial provides a command line configuration guide for developers and a docker image for multiple platforms, including a concise introduction of nodes and mining settings. Follow the instructions here: Quick Start with QuarkChain Mining.
Next we will continue to release: A tutorial for community members who don’t have programming background. In this tutorial, we will teach how to create private QuarkChain nodes using AWS, and how to mine QKC step by step. This tutorial is expected to be released in the next few days. Programs and APIs integrated with GPU / ASIC mining. This is expected to allow existing miners to switch to QKC mining more seamlessly. Frequently Asked Questions: 1. Can I use my laptop or personal computer to mine? Yes, we will provide cluster software and the demo implementation of CPU mining to the public. Miners will be able to arbitrarily select one shard or multiple shards to mine according to the work difficulty and rewards of different shards. 2. What is the minimum requirements for my laptop or personal computer to mine? Please prepare a Linux or MacOs machine with public IP address or port forwarding set up. 3. Can I mine with my GPU or an ASIC machine? For now, we will only be providing the demo implementation of CPU mining as our first step. Interested miners/developers can rewrite the corresponding GPU / ASIC mining program, according to the JSON RPC API we provided. With the upgrade of our testnet, we expect to provide the corresponding GPU / ASIC interface at a later date. 4. What is the difference among the different mining algorithms? Which one should I choose? Double SHA256 is a computational intensive algorithm, but Ethash and Qkchash are memory intensive algorithms, which have certain requirements on the computer’s memory. Since currently we only support CPU mining, the mining efficiency entirely depends on the cores and speed of CPU. 5. For testnet mining, what else should I know? First, the mining process will occupy a computer’s memory. Thus, it is recommended to use an idle computer for mining. In Testnet 2.0 settings, the target block time of root chain is 60 seconds, and the target block time of shard chain is 10 seconds. The mining is a completely random process, which will take some time and consume a certain amount of electricity. 6. What are the risks of testnet mining? Currently our testnet is still under the development stage and may not be 100% stable. Thus, there would be some risks for QuarkChain main chain forks in testnet, software upgrades and system reboots. These may cause your tQKC or block record to be lost despite our best efforts to ensure the stability and security of the testnet.

Questions Answers
What was it like being raided? GAME OVER PLEASE INSERT COINS.
Do you have any regrets about your involvement with those groups? Snowden, hero or villain? Why? There's no point regretting anything because you cannot undo the past. I heard about Snowden in prison, came on the news but I only know what the news has been telling me. I will look more in to it, he's got balls I can tell you that and I admire a good set of balls.
Really? Good set of balls? Are we not doing phrasing anymore? Yes really.
Any advice on learning how to program? I'm struggling with Python at the moment. You don't learn how to program, you learn how use a programming language, programming is what you do with that information. Read lots of examples of source code, see if you can work out whats going on. Don't just copy/paste the examples, write them word for word no matter how long they are. Not only will it help understand what it is doing better you may also learn a few tricks.
That's deep man. Thanks for the advice. No problem.
You don't learn how to program, you learn how use a programming language. Damn, pretty sweet quote there. It's also true.
How did you get started 'hacking'? I first started back in 1998 I mostly used to hack PC games, hex editing, binary reverse engineering stuff. Then I learned how to use C and assembly and it just went from there.
What do you recommend for someone that's interested in hacking(in terms of learning it)? Hacking is the art of reverse engineering, before you can reverse engineer something you need to have an in depth knowledge of it.
What are your thoughts on mass surveillance? Any advice for the masses? It's been going on longer than you or I have existed. Strong encryption is the key.
Ever considered a job with the NSA? GCHQ? I don't think I would pass the security clearance now anyways. I am x military though so who knows.
I am surprised you are allowed to use computers or the internet at all now considering some of the parole conditions of many American hackers. Can you talk about some of the restrictions in the SCPO and why you feel they are unfair? Basically it prevents me from using encryption that allows hidden volumes, virtual machines and I cannot delete my internet history. It lasts for 5 years and each breach of the order can be punishable up to 5 years.
It's not a case of them being fair or unfair. I can't go too in to detail about it if I want to take it back to court, I just want to challenge it, plus I like to keep my cards close to my chest.
So would say firefox's private browsing mode be against the rules? I don't think so, I'd have to check the src of firefox to determine if it deletes the history in private mode or if it simply does not record it in anyway. The order says "Not to delete".
So if you just image a fresh install of your variety of os(debian?) everyday would that break your parole? I could just boot live OS and not be in breach.
Is that what you do? I used to, remember slax?
Are you proud of the sacrifices you made in your lifetime? Yes I am, I never look back I just move forward in to the future hoping to find peace and happiness.
Did you meet anyone interesting in prison? There's some funny characters in prison I can tell you that, made friends for life. Most of the people in there were in there for fraud, drugs, gang stuff. I never met any famous prisoners if that's what you mean? Then again everyone's story in prison is interesting.
What is the best way to protect your digital identity, and secure your privacy? Since you have experience exploiting these vulnerabilities, what do you suggest to prevent it? Strong encryption, limit the amount of personal information you place on the internet, don't draw attention, only use a sandboxed browser and tunnel your HTTPS through SSH using the highest of encryption, PGP mail for every mail, don't store encryption keys on your computer, full disk encryption and/or hidden OS, use different emails for your banking, paypal etc, Mak3p4$5w0rdZ!nCr3d!b4LlYsTr0nG, uninstall flash use Link to youtube.com instead etc, etc...
Thanks for your answer. I am not worried about personal use, I am more worried about enterprise and or security systems. preventing people from hacking my companies website, and social media accounts. I have to keep in compliance with the financial standards, so we use PGP, and Erado, for archiving and encryption. It is just nice to get the perspective what is an easy target, what would you consider a difficult target not worth pursuing? I could write a book to answer this...
Security isn't something you can just apply it's an on going process and in most cases you are relying on products sold to you on a trust basis. You're told that Antivirus software will stop you getting a virus but what you're not told is that Antivirus software only protects you against what is known, takes less than an hour to write a new piece of malware or backdoor that your AV will never detect.
People put too much faith in to security systems without understanding how they work, their capabilities or limitations.
There's no need to be "pentested" it's a right con, they only test you against old exploits, if you update regular then you're already safe.
Use 2 factor authentication and/or strong password policy, prevent users creating the own password (they will only make them simpler)
Just make your data worthless to a hacker by encrypting it.
Insightful, thank you. I know it's a vague question, but you just confirmed my intuition. Thanks for your honest answers. No problem.
Was it worth going to prison? Nothing is worth going to prison for. Yeah they are happy I am back and I am happy to see them again. It was ~100GBP for my parents to come and visit me in prison, I was a long way from home. I told them not to waste their money because the visit only lasts 2 hours.
How is your family treating you, are they happy to have you back? Did they visit you in prison? I am x military I am used to being away from home for long periods of time. It also makes time fly faster when you're not constantly reminded about home. If you don't know what you are missing then you don't miss much.
I've never been to prison, but I lost about 8 years of my life due to bad medical advice. I used to be angry-- I was thinking why wasn't it only 2 years-- why did it have to be such a complete waste of so many years? Would that have happened if it had been only 2 years instead of 8? I don't think so. Sometimes, events like that helps to put things in to perspective. We often don't think about our lives on a day to day basis but when something out of the "norm" happens it makes us think that little more.
What do you think about bitcoin? where will it be in 10 years? I think it's great, scrypt coin too! I think they will get heavily regulated soon though. I had 78 bitcoins backed up on a SDHC before I was sent to prison. Back then they were worth ~$40 each. Come out of jail and I can't find that shit anywhere lol.
The only problem is even if I do find it, it's encrypted with keys that are on the computer the police confiscated and I can't get back.
I know right?
Sue them. They stole you $ 78k. It's killing me!
If they've not destroyed your computer or had a seize order against it then you can get back things like that. Ask your lawyer. They seized it in court, I can however apply "for a copy of evidence" under UK law and they would have to give me a copy of the HDD.
Do this. Those bitcoins won't last. How long untill they are orphaned? It's been ~3 years already.
No idea. I meant they won't last as a concept (especially not at that value). Wow, only just seen it but they peaked at ~$1000? Feels bad man.
Exactly - since then the Chinese and Russians have banned it, and you can only consider it's a downward spiral from there. I wonder how long it will last here in the west, I'm surprised it hasn't already been regulated the tax man must be pissed!
I think there are also more constructive uses for mining, I mentioned this on twitter also. See there are a lot of cancer researchers and scientists that have HUGE amounts of data that needs to be mined to help cure diseases and solve the worlds problems.
The world hash rate for crypto coins is more powerful than most of the worlds super computers combined. Cancer researchers should give coins for mining cancer research data instead of wasting time generating meaningless hashes.
Do you like sporks? Yes, I do, do you?
Hey man we are asking YOU the questions here. Leave the interrogations to us the professionals. Ok bro.
Ex Army eh? Signals? or Tech in REME? I was in the Infantry.
So how were you ID'd for arrest? I fucked up, I've already explained it on here, lurk moar.
Just curious, do you think big brother is reading this ama real time or at all? They will be on this like flies round shit.
Where does/did LulzSec congregate? What is the education background of a typical member, or from where did you learn to do what you can do? We had our own private IRCD and encrypted silc servers, also channels on public servers. I am completely self taught, I have been at it since 1998.
Isn't the true "lulzy" part of this that you guys bugged some people and mocked their security and then ended up getting busted and going to prison while the companies you annoyed made their security better? That's pretty lulzy to me. What I find lulzy is the fact they were all vulnerable to webapp vulnerabilites and don't use PGP.
Wasn't LulzSec responsible for the major Sony Online Entertainment security breach? I know you wanted to retaliate because SONY was suing George Holtz for the PS3 jailbreaking thing he did, but the only thing that happened is that you inconvenienced the people. Basically I am asking. Why did you ruin all those accounts, which lead to people having their credit cards stolen, instead of just attacking SONY directly. Also, how many accounts were compromised? LulzSec says 1000, SONY says ~4000. LulzSec had nothing to do with the PSN breach, fact.
Do you suspect who was responsible? (group name, not actual name) Honestly, no Idea there is too much internet rumor and no one has officially come forward to claim it. I read some people in Spain were arrested and questioned in relation to the PSN breach but that still doesn't mean it was them.
What are your political views? I don't really have any political views, however I would like to see the rest of the world get a chance to sample democracy and be free from oppressive dictatorships (no naming names).
At first welcome back. So here an total haxolulz/past unrelated question what kind of music do you like? I like Hard Dance music, Hard Trance/Hard House.
Fuck yeah! Trance and House all the way. I used to have a set of Technics 1210 Mk2 and mix like mad when I was younger, still got some of the vinyl haha.
Hackers soundtrack, orbitals by halicon. Not hard but one of my favorites. Thanks I'll check this out. The LuLzSec hacker song by ytcracker is the ONLY hacker song haha.Link to www.youtube.com
Who is your favorite Trance artist? Ever been to any festivals? Tidy boys, nothing but. Their events are awesome, youtube "Tidy weekender"
How came you guys got the cia down? It was hit with a 100,000 node botnet.
What does this mean in layman's terms? 100,000 computers were used to send ALOT of data to the server causing it crash.
That's as simple as it gets.
Any advice for aspiring hacktivists? Trust no one.
Still on 4chan? fav boards? Rules 1&2 always apply.
Hate to break it to you bro, but 4chan is just full of kids now. The rules of the internet have somewhat faded since you left the intertubes in 2011 :( consequences will never be the same again. Ebaums world has been dead a longtime because people broke 1&2
What's your opinion on the book by Parmy Olson? I think I recall she said she talked to you by chat, but how accurate was what eventually made it into the book? I lost the book before I could read it all so I don't know...
What do you think your job prospects are now with the conviction hanging over your head? Not too good! I'm on my arse at the minuet, I'll do any job!
Any job? ( ͡° ͜ʖ ͡°) Allmost...
Write a book. Is it really needed?
Not needed per se. But you can tell an autobiographical perspective that nobody else can. The story lulz & Anon supporters would want to hear. Obviously not a 'tell all' but a 'tell most'? Yeah I get what you mean.
Was there a time before you were caught that you were worried or thought the authorities might have a clue as to your real identity? I knew I was going to get caught, I fucked up.
Did you have a backup plan? There was no backup plan but I realized the mistake early and acted accordingly! No I do not own guns, they're a lot more restricted here in the UK.
Are you still in touch with Jason? Saw he went to prison recently, I actually went to HS with him. How long did he get?
Jeremy, not Jason. Twins. Yeah, I think he got 10 years or something like that? I've not heard anything from him since I got out, hope he is ok.
I look up to you on how you managed to convince everyone you're a girl, smart and funny thing at the same time. Really I look up to you like a celebrity, hah. Maintaining a strong persona such as kayla and doing what I did wasn't easy. If I could go back in time I wouldn't change anything, I'd just keep going back in time to relive it over and over again. Nothing is worth prison time, it's a waste of life however I did manage to get some qualifications out of it. Not many people can say they left prison with a diploma for the thing they went in for.
If you could go back in time, before the creation of Lulzsec, what would you do differently? Also, was Lulzsec's missions worth the prison time? Where did you learn social engineering, and hacking? I learned to do what I do from programming, it is simply reverse engineering.
Thank you for your answer. What do you think about the Syrian Electronic Army, their methods of attacks, and their meaning? I honestly believe they are state sponsored (possibly not from the beginning) but I do believe they are the people Assad is turning to. As for their methods I don't even know what methods they are using, I'll read in to it though, I'm fresh out of prison and most of what they have done was done while I had no internet access. I've been banned from the internet since 2011.
That they are, got many of Advanced Replacements on products. If you had to choose between, Windows or OSX which would you choose. I'd choose Windows, I'm not a fan of OSX.
This is probably the longest I've ever seen someone take questions in an AMA. Thank you for dedicating so much time to answering people's questions. No problem I enjoy answering questions and I will be here until the questions dry up.
How did it feel being able to get behind a computer for a first time in 2+ years? Did you build a rig to re-live the novelty or do anything particularly special? Porn, me thinks. I was able to use computers in prison. I was given a job as a class room assistant helping teach people about computers, basic things. I also managed to complete a number of computer related qualifications and gained a diploma. Seeing the internet after 2+ years was kind of strange though. The internet looks a lot different now compared to how it did in 2011. To be honest I don't like it, it has that "iphone look" to it all, big buttons and lots of unneeded JS. I wish I could build a rig I just do not have the money to do so. Hopefully soon I will find a nice job and maybe then I will build one.
Did you have internet in jail? No they do not allow internet in UK prisons.
Do you think access to the internet should be a human right? When will it be? Yes it should be and I am sure it is already so!

My question: Did you ever have any suspicions about Sabu? At any point did you guys think, Something is up with this dude? Everyone had suspicions about everyone, things were being patched, rootkits disappearing, logs being leaked etc..
Was prison anything like you had expected it to be? Better than I thought it would be, I had most prison movies flashing in my head on the way there from court but it's nothing like that.
Could you elaborate more on what it's like please? Once I got to prison I realized it's nothing like the movies. Because it was all over the news when I was sentenced everyone in the jail knew who I was and what I was in for. I've made some good friends out it, people I am going to meet again once they are free. No one was ever violent towards me, you don't give any attitude you don't get any attitude. I did see some people get fucked up in there, mostly starts over something really silly, like a game of pool.
How did you pass the time? I used to pass the time playing chess with my cell mate or by watching all crazy people in there.
Did you personally encounter much violence in the prison? Or is it easy enough to stay away from it if you don't rock the boat or whatever? Well, most of the prison movies I have seen all show people stood at the bars, big guys growling "mmm fresh meat" and everyone getting stabbed up every 2 minuets. When you've never been to prison before you can't help but think back to every movie you've seen about prison.
When do you think the govt will evolve enough to have guys like you helping to grow our society? Right now it seeks to hunt you down...terrible waste of resources imo It is, there's a lot of talent rotting away in the prison system.
Administrations that in one breath expresses the need for engineers of digital space and then issues the order to capture the very people with such talents. Edit: its been many administrations haha :*( And many more to come!
Its wishful thinking but i hope that the economic imperative will win out as we progress to what can be depicted best by the Type I civilization coined by popular theoretical physicist Michio Kaku. Things need to change, that's for sure.
Is Milhouse a meme? Milhouse was the best meme!!
Do you like Wheatus? No, Wheatus sucks.
How do they ? Well I just like to suck wheats thats all.
What do you think - in Wrestlemania '98, did Mike Tyson get punched in the cock? Never watched it back then, I hope so!
Are you now like Gavin Orsay (Jimmi Simpson) on House of Cards? Never watched it, only just got out of prison I've heard a lot about that series, I'll look in to it.
Gavin in House of Cards has a guinea pig. Reminded me of "Noodles". :3. Hahaha.
the character Gavin is this hacker and there's a scene where he tells his FBI handler that they have to drop charges against Barrett Brown. Link to www.youtube.com Really?
Indeed. And check out who advised on the new season of HoC :3. Link to www.theguardian.com. HAHAHAHAHA.
Do they let you have PlayStation in British prisons? Link to www.dailymail.co.uk. They do if you buy the PlayStation.
What did you have in your cell? TV, Kettle, Radio, Bed, locker and that's it... I wasn't bothered about a play station, just used to play a lot of chess and poker.
What sort of people did you meet in association with the hacking groups? What kind of people are hackers? Out of everyone I have met there are only a small handful of people that I would put in to the "reverse engineehacker" bracket. Lots of people who know how to use exploits, not many who know how and why they work or are able to write their own, truly is a dieing art.
Do you ever think about trying to get hired for security for websites or for government computers or something along those lines? Again it's probably a trust issue...
Personally, I was very stupid and didn't really care about the ease with which personal information can spread, and didn't know how widespread NSA surveillance was. Given that a lot of stuff is out there already, if someone wanted to take the time to look at it, do you have any advice as to how to minimize the damage? Strong encryption is the key but to be honest, Internet Service Providers should be doing more to protect it's customers privacy, they should allow AES256 pipes for every customer as standard.
Many (fairly intelligent) people I talk to agree that they are concerned about surveillance and privacy on the internet, but they're resistant to try and use encryption or anything because they have it in their heads that only supergeniuses can understand computers like that. Do you have any suggestions for introducing these concepts to slightly technophobic people? I think encryption needs to be simplified for the regular user. It can get a bit confusing if you have never used it before or understand it's significance.
Also, wanted to thank you for your advice to the person below asking about how to learn programming. I know a little introductory Python, but I never really knew how to go from there to creating and understanding a whole big project. Programming languages too, learning new things is never easy, it's about determination and the will to succeed. The best way to learn is to read lots of source code and try to work out what is going on, maybe you could even improve on it?
How did you learn to hack? From learning to program.
Hacking is reverse engineering, it's an in depth knowledge of the underlying system/code/hardware/technology and the ability to take it apart piece by piece and reassemble it in to something else.
How long did it take you to become a proficient programmer? How did you learn? How long did it take you to become a proficient reverse engineer? How did you learn? I just learned from doing, trial and error. If there was something that I did not understand I would just research it, it sometimes helps to read it from more than one source. I used to just read lots of examples and try to make sense of them, if I found something new or something I did not understand I would research it.
As for time, I am unsure... I am still learning now, it is an on going process. All I can say is learn the basics and be creative, if there's something you do not understand research it, google always has the answer.
Have you only just got out of prison? I have been out a few weeks but I have only been on the internet a few days now.
Ever hear from anyone in that channel? Just one, those times are sadly gone.
When you got V&, they said two men where arrested for using the Kayla alias in some media. What happened there? The other person was my brother, they were unsure if it was him or me.
Ahh, You're poor brother... what happened when you got raided, how many people, where did they take you? I was home alone, they arrested me and took me to the police station for questioning. They told me during questioning that they had also been to arrest my brother.
Is human body very good build pc with very cheap soft?If it's so easy to exploit:( No it's a design prone to failure.
I want to learn Python 3. Codecademy is Python 2 (like all good tutorials...they seem to be for 2). Thanks for the links. I'll look into them. At the minuet I am going over logic, reading into some Verilog and other HDL because I want to experiment with some Field Programmable Gate Arrays (FPGA).
Hey its Kayla! Hahaha.
Hey thanks for the advice in the thread . I'll definitely use that on my quest to getting my Computer science thread and furthering my programming language knowledge ! No problem.
Kayla, I just want to say thank you. Haha no problem.
Meanwhile, while you were in prison our gov't set up a fake twitter type service in Cuba with the intent of helping topple the Cuban gov't. -_- I'd like to see how you have come to this conclusion? Or is it official and that is it's official purpose?
I just find it ironic that while prosecuting with one hand the other is going to extreme lengths to topple a government with social media. It's usually the case.
You should try this at /netsec. Possibly, no way to link them over? I'll admit it, this is the first time I've ever used or been to reddit.
They would probably have a few more knowledgeable comments and questions. Doesn't seem like any of them took the bait!
Yea, go to /netsec and create a new post, and make it a link (to the url of this thread). Make the title basically the same, but bring up the fact that it's an xpost. Thanks, I'll do this after I've made a coffee!
My question: why didn't you guys get ahead of the game by targeting Google. They're the resident evil today. Care to explain?
I think he meant Umbrella Corp. They have their hands in everything, and are mercilessly expanding. Fist umbrella fuck with zombies, now google!
#tr0ll. Hahaha, I'd like to believe it but...

So is there a nice tutorial which explains how to start mining using FPGA. I do not want to create a fancy 2 - 10 connected FPGAs to run mine for profit, but I just want to start one FPGA and to see how it is working and what speed it is giving me. Recently, what looks to be the first open source FPGA bitcoin miner was released on GitHub. The code is based on the Terasic DE2-115 development board featuring the Altera Cyclone IV, however the author says the design should be applicable to any other FPGA. FPGA Bitcoin Mining. At the foundation of block creation and mining is the calculation of this digital signature. Different cryptocurrencies use different approaches to generate the signature. For the most popular cryptocurrency, Bitcoin, the signature is calculated using a cryptographic hashing function. Field programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing—hence "field-programmable".FPGAs are integrated circuits that can be tailored to suit a particular task like mining bitcoins, after their manufacturing thus creating ASIC.
