6 Best Bitcoin Mining Hardware ASICs Comparison In 2017

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.

Transcript of Open Developer Meeting In Discord - 5/10/2019

[Dev-Happy] Blondfrogs05/10/2019
Channel should be open now
Chill05/10/2019
you all rock!
just getting that out of the way :wink:
Tron05/10/2019
Cheers everyone.
theking05/10/2019
Hi fabulous dev team!
Hans_Schmidt05/10/2019
Howdy!
Tron05/10/2019
No specific agenda today.
Questions?
Has everyone seen Zelcore wallet, and Spend app?
theDopeMedic05/10/2019
Any major development status updates that haven't been listed in #news?
Synicide05/10/2019
How was the meetup yesterday? I heard it would be recorded, it is uploaded anywhere yet?
Tron05/10/2019
And Trezor support on Mango Farm assets?
@Synicide Yes it was recorded. The Bitcoin meetup organizer has the video.
I talked about Ravencoin, but mostly about the stuff that was being built on/with/for Ravencoin.
There was about 70% overlap with folks who were at the Ravencoin meetup in March.
Synicide05/10/2019
awesome, looking forward to watching it when it's available
Tron05/10/2019
I'll hit up James and see if he's posting the video.
S1LVA | GetRavencoin.org05/10/2019
@theDopeMedic I'd follow github if youre interested in development status
Synicide05/10/2019
zelcore looks super slick. Been meaning to research its security more with the username/pw being stored on device
Chill05/10/2019
How is the progress on the restricted assets and testnet coming along? A secondary question would be about the approximate fork timeframe.
S1LVA | GetRavencoin.org05/10/2019
Has anyone heard from the community dev (BW) working on Dividends?
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Any word on BW and his progress w dividends?
@S1LVA | GetRavencoin.org LOL
Tron05/10/2019
@S1LVA | GetRavencoin.org Great question. I haven't heard.
Synicide05/10/2019
last meeting BlondFrogs said he would try to connect with BW as he was sick with the flu at the time. Maybe he has an update
S1LVA | GetRavencoin.org05/10/2019
I've tried to get in contact, but with no success.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Got a funny feeling...
Jeroz05/10/2019
Last time we left off with someone mentioning a foundation and Tron saying let’s discuss that next time iirc
kryptoshi05/10/2019
Has anyone taken a look at the merits for this proposal? Thoughts? https://medium.com/systems-nexus/modified-x16r-algorithm-proposal-for-constant-hash-rate-in-short-time-164711dd9044
Medium
Modified X16R algorithm proposal for constant hash rate in short time
Interpretation Lens V. a0.01
Tron05/10/2019
I did see it. Does anyone think this is a problem?
Synicide05/10/2019
It looks interesting... but I'm not sure what it is trying to solve. Looking at netstats, our 1 hour average block time is perfectly 1 minute
S1LVA | GetRavencoin.org05/10/2019
Last I heard from him he expressed how important finishing the code was. I wouldnt jump to conclusions on his absence within the community.
Synicide05/10/2019
x16r by nature will fluctuate, but DGW seems to be doing a good job keeping consistent block times
Tron05/10/2019
Because of relatively broad distribution across the algorithms, the block times are fairly consistent. It is possible, but very, very unlikely to get a sequence that takes up to 4x longer, but that's super rare, and only 4 minutes.
We did some timing analysis of the algorithms early on. A few are 1/2 as long as SHA-256 and some are up to 4x longer. But when you randomly select 16 it usually comes out about even.
Synicide05/10/2019
1hr avg: 1.02min - 24hr avg: 1min
I think we should focus on building, and not trying to fix what isnt necessarily broken
Tron05/10/2019
Agreed.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Agreed
Tron05/10/2019
Is everyone ok with the frequency (every other week) of this discussion?
Jeroz05/10/2019
(Added thumbs down to measure)
Tron05/10/2019
@Jeroz Did you do thumbs-up and thumbs down?
S1LVA | GetRavencoin.org05/10/2019
Seems appropriate. Its not like the devs dont poke around here and chat anyways.
Tron05/10/2019
Anything critical that we should be aware of?
Jeroz05/10/2019
When I need a dev, I poke a dev. When that dev is unavailable. I poke another one :smiley:
Hans_Schmidt05/10/2019
BlondFrogs was testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Jeroz05/10/2019
I hope I didn’t offend any devs
With poking around
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Was thinking voting would be an excellent use case for restricted assets. Local communities, nations, etc... could kyc their residents
radiodub05/10/2019
Is x16r will remain fpga mineable
Tron05/10/2019
@Jeroz We're hard to offend.
Chill05/10/2019
Is the general dev feeling that the next fork should and will include everything needed for the next 6-9 months (barring something completely unforeseen)?
Jeroz05/10/2019
I know :smile:
Tron05/10/2019
@radiodub Nearly impossible to stop FPGAs and still keep GPUs
Jeroz05/10/2019
About that: voting is another hard fork right? Not too soon?
Tron05/10/2019
FPGAs can be reprogrammed as fast. It is silicon (true ASIC) that we can obsolete with a tiny change.
@Jeroz Messaging, voting, Tags, Restricted Assets would require a hard fork (upgrade).
We could do them each individually, but folks get weary of upgrades, so current plan is to roll them together into one.
MrFanelli™05/10/2019
Good idea
Jeroz05/10/2019
Oh voting too?
MrFanelli™05/10/2019
People will like that
Jeroz05/10/2019
I thought that was coming later
Tron05/10/2019
Voting is the one that isn't being worked on now. Tags and Restricted assets have taken precedence.
Jeroz05/10/2019
I know. But you plan on waiting to fork until voting is also done?
That would have my preference tbh
But I can see an issue with too many things at the same time
Tron05/10/2019
If someone wants to step in, we've had one of our devs sidelined and he was working on BlockBook support so more light wallets can connect to Ravencoin. Mostly test cases needed at this point.
S1LVA | GetRavencoin.org05/10/2019
Thats a pretty large upgrade.. Bigger surface for unknowns
Rikki RATTOE Sr. SEC Impresantor05/10/2019
At what point would RVN community consider moving to ASICs because having a Bitcoin level of security would eventually be needed?
MrFanelli™05/10/2019
Never rikki
Tron05/10/2019
@S1LVA | GetRavencoin.org 100% Lots of testing on testnet and bounties.
[Dev-Happy] Blondfrogs05/10/2019
I am here :smiley:
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor There's nothing inherently wrong with ASICs but it tends to centralize to data centers and less opportunity for anyone to just run their gaming rig overnight and collect RVN.
Welcome Blondfrogs
MrFanelli™05/10/2019
Asics are too expensive. If we want normal people to mine, then we cant be an asic network
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron True but what happens when the chain needs a Bitcoin level of protection?
Tron05/10/2019
More GPUs, more FPGAs
MrFanelli™05/10/2019
Nvidia loves ravencoin :stuck_out_tongue:
Chill05/10/2019
ok, so we are pro FPGAs
𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/10/2019
Build it and they will come
Tron05/10/2019
It's all relative. It is cost to attack. If an ASIC isn't available for rent, then only option is rental of non-allocated GPUs
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Chill Eventually everyone will need FPGAs to be profitable on RVN, at that point I don't see why we just don't make the switch to ASICs
Tron05/10/2019
Also, as much as we don't focus on price, the price does matter because it determines the amount of electricity and hardware will be deployed to get the block reward. Price increase means more security, more mining means more security means higher price.
It's a circle.
Chill05/10/2019
someone tell that to the twitter handler
HailKira05/10/2019
you guys adding seedphrase to desktop wallet?
[Dev-Happy] Blondfrogs05/10/2019
@HailKira We will, just is not a high priority right now.
MrFanelli™05/10/2019
Twitter handle wants rvn ded
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I just don't see much difference between ASIC and FPGA and I'd rather have the added nethash an ASIC will provide once GPUs are virtually kicked off the network
kryptoshi05/10/2019
I'm at 11 GB future proof
Tron05/10/2019
That also limits miners to big money, not gaming rigs.
Synicide05/10/2019
@Rikki RATTOE Sr. SEC Impresantor you have to keep in mind the 'added nethash' is all relative
Rikki RATTOE Sr. SEC Impresantor05/10/2019
FPGAs will limit miners to big $$$ too IMO
Tron05/10/2019
@kryptoshi New algo x16r-12G requires 12GB :frowning:
Seal <:cricat:> Clubber05/10/2019
But sperating smaller gb cards would lead to less adoption if we ever become a mainstream coin.
Adpotion of mining that is
Chill05/10/2019
but we are a mainstream coin
Seal <:cricat:> Clubber05/10/2019
Mains stream as in what eth did
Tron05/10/2019
@Rikki RATTOE Sr. SEC Impresantor I agree. Not a perfect solution.
Steelers05/10/2019
Is this a Dev meeting or Algo meeting :smiley:
Seal <:cricat:> Clubber05/10/2019
But if we ever go mem lane. We should aim for 6 or 8gb.
Tron05/10/2019
Open to other questions.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron Probably not the time and the place to have this discussion as we stand currently but IMO we're gonna have this conversation for real eventually
Seal <:cricat:> Clubber05/10/2019
Most cards have 6gb now.
kryptoshi05/10/2019
Why 12 gb ? Such a massive jump
Seal <:cricat:> Clubber05/10/2019
^
Would also like to know
Tron05/10/2019
@kryptoshi I was joking. You said you had 11GB card.
Seal <:cricat:> Clubber05/10/2019
Haha
You got em good
I cant imaghine the face he had when he was 1gb short
Lel
Rikki RATTOE Sr. SEC Impresantor05/10/2019
That's what she said
kryptoshi05/10/2019
Hahaha
MrFanelli™05/10/2019
need a 2080ti
Seal <:cricat:> Clubber05/10/2019
How much does the VII have?
16?
[Dev-Happy] Blondfrogs05/10/2019
Any other questions you have for us?
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs You were testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Chill05/10/2019
a dev might want to contact Crypto Chico for some 'splaining
[Dev-Happy] Blondfrogs05/10/2019
I still haven't contacted the developer that was working on dividends. Was pretty busy with some other stuff. I will contact him this next week, and see where we are at for that.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Chico doesn't do interviews, shame. Tron would be a much needed interview for his community
[Dev-Happy] Blondfrogs05/10/2019
As far as releasing dividends, I can be released at anytime the code is finished and doesn't require any voting or hardfork to occur
kryptoshi05/10/2019
Android asset aware wallet?
Seal <:cricat:> Clubber05/10/2019
Is in beta right
Tron05/10/2019
Testing went well today on Android. Nearing release.
[Dev-Happy] Blondfrogs05/10/2019
as it is a mechanism that is wallet specific
liqdmetal05/10/2019
no protocol level dividends you guys are saying?
[Dev-Happy] Blondfrogs05/10/2019
correct
Tron05/10/2019
DM me if you want to test Android with Asset support. I'll send you the .APK.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
RVN gonna be on tZero wallet? :yum:
liqdmetal05/10/2019
why not? what is the logic on non-protocol dividends
assets + protocol dividends is nirvana
[Dev-Happy] Blondfrogs05/10/2019
dividends is pretty much sending payments to addresses. Right now, you would have to do this manually. The dividends code, will allow this to be done quicker and easier.
No consensus changes are required.
Tron05/10/2019
New Android wallet is BIP44 and original Android wallet is BIP32/BIP39 so the words will not find the funds. You'll need to send them to another wallet, and then send them to new BIP44 derived address.
liqdmetal05/10/2019
we already have payments to addresses
so dividends is not a feature so much as simple wallet script
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs The dividend code changes look risky'er to me than messaging. Would you consider "tags" branch test-ready?
[Dev-Happy] Blondfrogs05/10/2019
Not yet @Hans_Schmidt
Dividends is easier then you would think if coded correctly. I still haven't seen the code from the community developer. Excited to view it though.
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs Sorry- I meant restricted, not dividend
kryptoshi05/10/2019
@Tron on the Android wallet, anyone successfully added their own node and got it to sync faster? Always have issues. I have a supped up node and cannot get it to work with the Android wallet...
[Dev-Happy] Blondfrogs05/10/2019
@Hans_Schmidt Oh, that makes more sense. Yes, they are very risky! That is why we are going to create a new bug bounty program for restricted assets testing.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Once the network does get flooded w FPGAs, should we even consider changing the algo a couple times a year? That would only give bitstream developers added time to hoard their creations for themselves
Kind of like they're already doing with their x16r bitstreams :yum:
kryptoshi05/10/2019
Flooded... lol... like that hardware has mass production scale like gpus...come on dude
MrFanelli™05/10/2019
Bip44 wallet? :smiley:
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@kryptoshi Eventually yes, where there's $$$ to be made, people make things happen
MrFanelli™05/10/2019
So can we trade from that in the new Binance Dex when RVN get listed?
kryptoshi05/10/2019
@Rikki RATTOE Sr. SEC Impresantor Yes Soon TM lol. :soontm:
Tron05/10/2019
@kryptoshi There are some things we can do to speed it up. For a new wallet, it shouldn't need to sync. For recovered wallet, it needs to sync from beginning of BIP44 wallet support on iOS so words can be moved between the two.
Other options include grabbing the first derived address and looking it up on an explorer to see when it was first used and sync from there.
Another option is to add an optional number with the 12 words so it knows when to start syncing.
There isn't a good reason on an SPV wallet to sync before the seed was created.
kryptoshi05/10/2019
Cool. Glad you are looking at speedup options.. :right_facing_fist: :left_facing_fist:
[Dev-Happy] Blondfrogs05/10/2019
@MrFanelli™ If the binance dex support RVN deposits. I am sure you would be able to send from it
MrFanelli™05/10/2019
Has binance reached out for any info or anything?
I seen that we ranked in some voting competition they had on twitter
for an ama
Rikki RATTOE Sr. SEC Impresantor05/10/2019
I believe we'll need to create a fund of approximately $300,000 in order to get a BNB-RVN asset created and listed on the Binance FDEX
[Dev-Happy] Blondfrogs05/10/2019
In order to work with binance we need Ravencoin integrated into Blockbook.
Tron05/10/2019
@MrFanelli™ I've reached back out to Binance on the AMA.
MrFanelli™05/10/2019
Awesome :smile:
kryptoshi05/10/2019
@Tron you are a natural on the interviews... cool as a cucumber. :sunglasses:
Tron05/10/2019
Thanks @kryptoshi
[Dev-Happy] Blondfrogs05/10/2019
Cool. We are done for today.
Please don't ask us any more questions :smiley:
Tron05/10/2019
Thanks everyone!!!!
[Dev-Happy] Blondfrogs05/10/2019
Cya everyone!!

[Very long, very serious] Development summary week ending 18th April 2014

When I got my first full time job, I used to try implementing requests from everyone as they came in, and for a while people really loved that I listened to their requests. Over time, however, things started to go wrong. I’d apply a change someone asked for, and in doing so would break something elsewhere in the code, in some subtle way that was missed in short-term testing. I’d fix that second bug and reveal a third. I’d fix that just in time for a new request to come in, and the process repeat. This led to the term “Bug whack-a-mole”, wherein I was spending time mostly fixing bugs introduced to live systems through rushing through earlier bug fixes.
So this week, we’ve had a lot of people asking about changes to proof-of-work, especially X11, or even moving to proof of stake, primarily in an attempt to address risk of a 51% attack. A 51% attack is where one actor (person, group, organisation, whatever) gains control of enough resources to be able to create their own blockchain, isolated from the main blockchain, at a rate at least as quickly as the main blockchain is being created. They can then spend Dogecoins on the main blockchain, before releasing their fake blockchain; if their fake blockchain is longer than the existing blockchain, nodes will switch to the new blockchain (as they would when repairing a fork), and essentially the spent Dogecoin on the main blockchain are reversed and can be spent again. This is mostly of consequence to exchanges and payment processors (such as Moolah), who are most likely to end up holding the loss from the double-spend.
The concern about a 51% attack stems from a couple of weeks ago now, when Wafflepool was around 50% of the network hashrate (mining power). It’s still high (at the time of wring about 32GH/s out of almost 74GH/s, or about 43%), but it is diminishing as a proportion.
Lets talk about proof of stake first, as this one’s simpler. Proof of stake has been suggested as a way of avoiding the risk of Wafflepool having control of too many mining resources by itself, by changing from securing the blockchain through computational resources (work), to using number of Dogecoin held. The theory is that those with most Dogecoins have most to lose, and will act in their own interests. Major examples of proof of stake coins include Peercoin, Mintcoin and more recently Blackcoin.
However, this essentially means we take control from Wafflepool, and hand it to Cryptsy (who are considered most likely to be the holder of some of the huge Dogecoin wallets out there). I by no means expect either organisation to attempt a 51% attack, but hopefully it’s clear that simply switching risks isn’t actually improving things. I’ve also had significant concerns raised from the merchant/payment processor community about potential impact of proof of stake, and that it may encourage hoarding (as coins are awarded for holding coins, rather than for mining). The price instability of Mintcoin and Blackcoin (and that Peercoin appears to only avoid this through very high transaction fees to keep the entire network inert) does not encourage confidence, either. For now, proof of stake remains something we’re keeping in mind, primarily in case price does not react as anticipated to mining reward decreases over time, but certainly we’re not eager to rush into such a change.
Before I get into a discussion on proof of work, let me summarise this quickly; right now, uncertainty about changes is holding back our community from adopting ASICs. It’s high risk to spend hundreds, thousands or in some cases significantly more on ASIC hardware which could be left useless if we move. Those who have already purchased ASICs to support the Dogecoin hashrate would most likely have to mine Litecoin to recover sunk costs, if we did move. ASICs are virtually inevitable, and in our assessment we are better off pushing for rapid adoption, rather than expending resources delaying a problem which will re-occur later.
At the time of writing the development team has no plans to change proof of work algorithm outside of the eventuality of a major security break to Scrypt. We are focusing on mitigation approaches in case of a 51% attack, and adoption of the coin as the most sustainable approaches to dealing with this risk.
The X11 algorithm has been proposed as an alternative proof of work algorithm. X11, for those unaware, was introduced with Darkcoin. It’s a combination of 11 different SHA-3 candidate algorithms, using multiple rounds of hashing. The main advantage championed for Darkcoin is that current implementations run cooler on GPU hardware. Beyond that, there’s a lot of confusion over what it does and does not do. As I’m neither an algorithms or electronics specialist, I recruited a colleague who previously worked on the CERN computing grid to assist, and the following is primarily his analysis. A full technical report is coming for anyone who really likes detail, this is just a summary:
A lot of people presume X11 is ASIC resistant; it’s not. Candidate algorithms for SHA-3 were assessed on a number of criteria, including simplicity to implement in hardware. All 11 algorithms have been implemented in FPGA hardware, and several in ASIC hardware already. The use of multiple algorithms does significantly complicate ASIC development, as it means the resulting chip would likely be extremely large. This has consequences for production, as the area of a chip is the main determining factor for likelihood of an error in the chip.
The short version being that while yes it would take significant resources to make an efficient ASIC for X11, for a long time Scrypt was considered infeasible to adapt to ASICs. As stated earlier, any move would most likely be nothing more than an extremely expensive and risky delaying manoeuvre. ASIC efficiency would also depend heavily on ability to optimise the combination of the algorithms; a naive implementation would run at around the rate of the slowest hashing algorithm, however if any common elements could be found amongst the algorithms, it may be that this could be improved upon significantly
There are also significant areas of concern with regards to X11. The “thermal efficiency” is most likely a result of the algorithm being a poor fit for GPU hardware. This means that GPU mining is closer to CPU mining (the X11 Wiki article suggests a ratio of 3:1 for GPU/CPU mining performance), however it also means that if a way of was found to improve performance there could be significantly faster software miners, leading to an ASIC-like edge without any of the hardware development costs. The component algorithms are all relatively new, and several were rejected during the SHA-3 competition for security concerns (see http://csrc.nist.gov/groups/ST/hash/sha-3/Round2/documents/Round2_Report_NISTIR_7764.pdf for full details). Security criteria for SHA-3 algorithms was also focused on ability to generate collisions, rather than on producing hashes with specific criteria (such as number of leading 0s, which is how proof of work is usually assessed).
X11 is a fascinating algorithm for new coins, however I would consider it exceptionally high risk for any existing coin to adopt.
Beyond algorithm analysis, this week has been mostly about testing 1.7. Last weekend Patrick raised the issue that we had been incorrectly running the automated tests, which had led to several automated test failures being missed earlier. This led to other tasks being dropped as we quickly reworked the tests to match Dogecoin parameters instead of Bitcoin. So far, all tests have passed successfully once updated to match Dogecoin, however this work continues. On the bright side, it turns out we have a lot more automated tests than we realised, which is very useful for later development.
The source code repository for Dogecoin now also uses Travis CI, which sanity-checks patches submitted to the project, to help us catch any potential problems earlier, thanks to Tazz for leading the charge on that. This is particularly important as of course we’re developing on different platforms (Windows, OS X, Linux) and what works on one, may not work on others. Over time, this should be a significant time saver for the developers. For anyone wanting to help push Dogecoin forward, right now the most productive thing to be doing is testing either Dogecoin, or helping Bitcoin Core test pull requests. Feel free to drop by our Freenode channel for guidance on getting started with either.
Right now, I’m working on the full technical report on X11, and will then be back working on the payment protocol for Dogecoin. I’ve approached a few virus scanning software companies about offering their products for Dogecoin, with so far no response, but will update you all if I hear more.
Lastly, the next halvening (mining reward halving) is currently expected late on the 27th or early on the 28th, both times GMT. Given that it was initially expected on the 25th, we’re obviously seeing some slippage in estimates, and a total off the top of my head guess would be that we’ll see it around 0500 GMT on the 28th at this rate. I have taken the 28th off from the day job, and will be around both before and after in case of any problems (love you guys, not getting up at 5am to check on the blockchain, though!)

High memory FPGAs? Other newbie questions.

Background: My degree is in computer science. I've worked various jobs in IT related fields. I have programmed in a smattering of languages (C/Java/etc) and mostly worked at an application layer and up. In school I did take several computer hardware classes, and in one we built our own 16-bit MIPS CPU (with pipelining) in a circuit simulator that one of the professors had written himself in Java. We created our own DRAM cells, NAND/AND/XOetc gates, we created our own shifters and multiplexers, stuff like that. But again...in a Java GUI, not anything practical like verilog.
End goal: I like performance. I like to tinker and make things go faster. I missed the bitcoin (and altcoin) FPGA rush by about 2-3 years. Currently, GPU mining is dominated by so-called 'ASIC resistant' algorithms which mostly resist ASICs by requiring a large amount of RAM (800MB-2GB, depending on algo) as part of the algorithm.
Partly as a novelty for my personal use, and partly so that I have at least some level of knowledge of yet another IT field I can go into should I ever get laid off or sick of my current job, I want to learn how to program an FPGA for the purposes of implementing at least one of these ASIC-resistant algorithms. The energy savings over a GPU would be nice as well, as from what I can see most FPGAs are at least an order of magnitude, if not two, more efficient than a GPU.
So, on to my questions:
  1. Xilinx seems to be the number one 'newbie' FPGA maker (I say this because I see them mentioned more frequently than any other maker in threads foby newbies). Apparently I can download their software kit and use their simulator to design and test in software; I don't need the actual FPGA circuit/card until I am ready to put my design 'into production'. Am I correct in thinking this? Are there other manufacturers I should target instead?
  2. Given my school experience designing circuits at something like a UML or CAD level, are there any recommended paths I should look into, or is learning VHDL/Verilog a pretty hard requirement to implementing any design? I'm asking because I'm ignorant.
  3. Maybe best asked for later, but would the Xilinx simulator give me some idea of which FPGA I'd want to buy? Will it give me anything approaching an 'expected behavior' ('hey, it runs at 1h/s on your CPU, but on our Model XYZ it will run around 300-400 h/s!') Or will there be anything useful in helping me pick FPGAs? Because...I already looked, and holyfuckballs there are a shitload of FPGA models and makers and ohgod how do I pick from this literal shitstorm of models?!
  4. Are high memory FPGAs a thing? I saw some stuff on Intel's website that indicated they had a (very expensive) FPGA that also had DDR4 slots built in. That would solve the memory issue. Do I actually need that though? Would it be the case that even a cheap (~$100) FPGA would end up having enough cells to implement 1GB of memory? I don't really care if I end up having a massive grid of registers, apart from the fact that, well, logic not used for computation is wasted energy and silicon space. But maybe 1GB of memory ends up being super tiny on an FPGA? Again, I understand how to build 1GB of memory in circuits, but not on an FPGA or in silicon.

Thoughts and wonderings about the Pow change

I’m new to crypto and I have a lot of respect for this community. I’ve found it to be an excellent source of insight for the crypto world in general, as well as for security/privacy practices. My technical understanding is limited but I do try to do my own research. I can’t really wrap my head around all this asic war drama and the purpose of this post is to gain a deeper understanding of it.
 
Official pow change announcement and the reasons for it:
https://getmonero.org/2018/02/11/PoW-change-and-key-reuse.html
 
‘An ASIC (Application Specific Integrated Circuit) is custom mining hardware that is specialized for a particular use. For example, Bitcoin ASICs are specialized to mine cryptocurrencies utilizing a SHA256 hash algorithm. Due to the fact that they are designed for a specific use, they will typically have a large performance advantage over hardware that is intended for general-purpose use like CPUs, GPUs, and even FPGAs. Thus, any newly developed ASIC will obtain a significant majority of the network hashrate and introduce centralization.’
 
So, using an ASIC is merely using the right tool for the right job? I understand that monopoly is bad and decentralization is good for stability, but since the algorithm is open source anybody is free to make an ASIC and compete. Won’t the market solve the monopoly issue itself? Both intel and Samsung seem to be getting in to the game, and it’s not like there’s a thousand gpu manufacturers. The market share of gpu manufacturers is split about 70:30 between nvidia and amd.
 
https://www.forbes.com/sites/marcochiappetta/2018/03/31/intel-patent-filing-for-efficient-crypto-mining-chip-could-reshape-the-gpu-landscape/#484991f21330
https://techcrunch.com/2018/01/31/samsung-confirms-asic-chips/
 
The free market seems to be a more permanent and sustainable solution than being dependent on continuous work of a small number of people. Is it possible that with planned pow changes some could have unfair head start to make their own ASICS ?
 
‘First, if mining is decentralized (because CPUs and GPUs are still usable for mining), it will be very difficult to pressure miners into not confirming a certain transaction, or otherwise act as a censor to the Monero blockchain.’
 
Even if you could get all the miners to ignore a certain transaction, how would they know which transaction to censor?
 
‘Second, it will lessen the pressure towards centralization of mining in large data centers (as can be seen in Bitcoin). ‘
 
Can’t you have large mining data centres with a shitload of gpu’s ?
 
‘Third, it is quite difficult for governments to regulate companies selling general-purpose hardware (as opposed to companies selling specialized hardware).’
 
I imagine oppressive governments could more easily detect and regulate electricity consumption itself with taxes, limits and reductions. If they license or ban mining itself it doesn’t really matter if your using ASICS or not, you would be illegal either way.
 
Monero is a great project, it shines because of its prime features: privacy and fungibility. The devs have been doing an awesome jobs bettering it, but since this is a trustless community and not a personality cult one does wonder why did it suddenly become about choosing who makes money mining it?

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!
Here you go Link to www.wired.co.uk
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...

First a bit of perspective on FPGA mining.. Around 2011 some miners started switching from GPUs to FPGAs, (Field Programmable Gate Arrays), after the first implementation of Bitcoin mining came out in Verilog, (a hardware design language that’s used to program FPGAs).. The general rationale behind FPGAs is to try to get as close as possible to the performance of custom hardware while also BitCoin Mining FPGA Card. By Bitcoinster Posted in Videos. Posted on October 12, 2019. I picked up a few PCI FPGA Cards on eBay for 99p which, apparently, can mine BitCoins at a speed of 21 Ghash/s (once they’re correctly configured!) source.
