The question occurred to the team at the online backup service iDrive, which performs most of its customer backup jobs overnight, leaving its 3,000 quad-core servers idle for much of the day.So the company ran a test with 600 servers to see whether Bitcoin mining could become a secondary revenue stream.The result: running Bitcoin mining software on those 600 quad-core servers for a year would earn about 0.43 Bitcoin, worth a total return of about $275.08 at current prices on major Bitcoin exchanges.“Its a waste of time, so any other company thinking about mining with their infrastructure, learn from us,” said iDrive’s Matthew Harvey.You need custom machines to effectively mine bitcoins and generate a real ROI.” The iDrive test-drive reinforced a common theme on Bitcoin mining forums: To earn money by mining, you need to invest in highly-customized computers using ASICs (Application Specific Integrated Circuits) to crunch data for creating and tracking bitcoins.Bitcoin is sometime referred to as the “Internet of money,” a platform using cryptography and software to offer an alternative currency and payment-tracking system.

At its heart is a huge distributed computing network that verifies each transaction.Participants in this online ledger are rewarded with new bitcoins, which are issued about every 10 minutes.Over the past year, the computing power supporting the bitcoin network has soared.The cryptocurrency is now supported by a powerful global network backed by 150,000 petaflops per second of computing power, roughly 600 times the combined power of the all the supercomputers in the Top500 list.Practitioners of Bitcoin mining – the term for using data-crunching computers to earn newly-issued virtually currency – are adopting more powerful hardware, pooling their efforts and seeking to slash their power bills.Most serious Bitcoin miners have graduated from CPUs and GPUs to specialized chips such as FPGAs (Field Programmable Gate Arrays) or ASICs that can be optimized for specific workloads.This has led to the emergence of a new class of hardware vendors selling custom hardware for bitcoin mining.The horsepower required to succeed in Bitcoin is highlighted by the iDrive simulation, which used 600 servers.

“Our study projected a year of mining at 100 percent processing power 24/7 and the assumption that the difficulty of mining (the calculating of hashes) would increase linearly,” iDrive noted in a blog post describing its experiment.“In the end, we learned a lot about the interesting process of bitcoin mining, however, for us, the pros did not outweigh the cons.So, IDrive decided to stick with that we do best.” They’re not the only ones who’ve contemplated repurposing powerful equipment to pursue cryptocurrency, The 4,000-core Odyssey supercomputer at Harvard was secretly used to mine Dogecoin, the ironic virtual currency used primarily for online tipping.The covert miner has had their computing privileges at the university suspended.Forum rules The more people that are involved, the more interesting this AMA series will be for everyone.Please help spread the word of this amazing AMA series on your own social media.(Hashtag: #BTCAMAWhen the AMAs are finished, all the answers will be compiled into a free E-book!

zooko AMA Posts: 32 Joined: Mon Nov 02, 2015 6:56 pm Location: Boulder, Colorado, USA I'm Zooko Wilcox, CEO of the Zcash Company.My name is Zooko.I've been privileged to spend almost all of my adult life working on the things that I love and care about: technology that protects and empowers people.At age 19, I joined the cypherpunks mailing list.At age 21, I went to work at DigiCash under David Chaum.Next I contributed a little bit to PGP (not much — just helped port it to HP-UX), worked under Eric Hughes, where I met Bram Cohen, then Bram and I were two of the four engineers who built Mojo Nation.I co-invented ZRTP with Phil Zimmermann, then I co-invented Tahoe-LAFS with Brian Warner.More recently I've been a co-author on BLAKE2 and SPHINCS (the most well-known of my co-authors on that one is Daniel J. Bernstein).At some point in my journey Aaron Swartz, Mark S. Miller, and I came up with an idea that Mark Miller named “Zooko's Triangle”.(Ifnothing in that paragraph makes sense to you, don't worry about it.)Today I'm the CEO of the Zcash Company.

We just announced Zcash (formerly known as Zerocash and Zerocoin), and released the "alpha" technology preview code for other developers to start learning it, contributing to it, and building on top of it.Here's my initial blog post about what Zcash is and why we're creating it: https://z.cash/blog/helloworld.htmlWe've received tremendous support from the community, for which I am deeply grateful.Here are some quotes from members of the community affirming that they too believe that privacy is important and that we have a chance to do something about it: https://z.cash/buzz.htmlThere has been some mostly positive and mostly accurate press coverage of it.Here are a couple of my favorite pieces in the press:* “Zcash, an Untraceable Bitcoin Alternative, Launches in Alpha” by Andy Greenberg (Wired) * “Zcash, a Privacy-Focused Alternative to Bitcoin, Launches Technology Preview” by Giulio Prisco (Bitcoin Magazine)I will start at 19:00 UTC this Monday, Feb 1, trying to answer every question to the best of my ability.

I look forward to meeting you and talking about Zcash.Please bring all your questions!(I'llhave only three hours at that time — I have to do something else at 22:00 UTC — but I can circle back and try to answer any lingering questions later.)UPDATE: I just posted a blog post describing the corporate structure and funding model: https://z.cash/blog/funding.html Last edited by zooko on Mon Feb 01, 2016 7:07 pm, edited 3 times in total.dill Nickel Bitcoiner Posts: 35 Joined: Fri Sep 18, 2015 11:11 pm Re: I'm Zooko Wilcox, CEO of the Zcash Company.BitcoinXio Global Moderator Posts: 107 Joined: Mon Sep 21, 2015 4:12 pm Re: I'm Zooko Wilcox, CEO of the Zcash Company.Get started with Bitcoin today!Buy bitcoin with your credit card Choose a Bitcoin wallet to secure your bitcoin flowdi Posts: 1 Joined: Sun Jan 10, 2016 1:21 am Re: I'm Zooko Wilcox, CEO of the Zcash Company.kingscrown Junior Mod Posts: 336 Joined: Tue Oct 27, 2015 3:50 am Re: I'm Zooko Wilcox, CEO of the Zcash Company.

Hello Zooko,I'm interested in reading your goals and motivations for taking on anonymity in general or anonymous digital cash specifically as your priority project?Haven't you seen the new laws coming (eventually in all Five Eyes countries I've heard from reliable sources) that will ban end-to-end encryption?To that end do you expect to support a viewkey or other way that users individually or a global backdoor, so that Zcash can be compliant with the lurch towards a 666 NWO which seems to be rapidly taking form now (and I assert will accelerate with the full global contagion sovereign debt collapse 2017 -2020)?I am all for the ideology, but I am also pragmatic.We as society may have to fight with social networking and the political-economic revolution of a DIY economy, e.g.self-publishing, 3D printing, etc.. I have been looking at the concept of a decentralized social network.Any comments?Sincerely,TPTB_need_warAnonyMintShelby Moore IIIEdit: please be aware of a rebuttal by ArticMine (afaik is a Monero/Cryptonote developer) to my question about a possible ban on end-to-end encryption, also note the desire for an answer concerning registration with FinCEN for your plans to fund your corporation or foundation with an 11% royalty on currency emission (creation).

Note I also mentioned that FinCEN issue in the "Fundamental challenges?"thread at the zcash forum.I have suggested you consider doing an ICO instead, and I think it would be wildly successful.IANAL so please do consult your own counsel, yet I will will make you aware of a thread of discussion I launched about whether crypto currencies are illegal unregistered investment securities under the Supreme Court "Howey test" in the USA.It seems likely that ICOs are illegal if openly offered to unsophisticated USA investors unless the ICO is registered with the SEC.The "Howey test" seems to be misconstrued by most interpretations and the Supreme Court explicitly stated that no obfuscation of the economic facts would diminish the efficacy of the intent of the securities law protection.Also there is some discussion about the interpretation of the FinCEN guidance which is an orthogonal issue to SEC regulations.The EU may have other regulations as well.Edit#2: Zooko if you have time, please read this single forum post of mine.

And so is Zcash.The entries that get appended to that ledger — the transactions — basically say "From Address", "To Address", and "Amount Transferred".The difference between Bitcoin and Zcash is that in Zcash those three values are encrypted, so that they aren't publicly readable by default.(Theperson who made a transaction could still make it be publicly readable, by publishing the decryption key, or could share the decryption key with selected parties to make it readable to them without making it readable to the world.That's what we call "selective transparency".)So far so good.Now the cryptographically challenging part is: how do we enable the miners and full-nodes to reject invalid transactions?This is where the zero-knowledge proofs come in.With zero-knowledge proofs, the creator of a transaction can include a proof that the transaction is valid (i.e.isn't a double-spend) without revealing anything about the encrypted "From Address", "To Address", or "Amount Transferred".Last edited by zooko on Mon Feb 01, 2016 10:55 pm, edited 1 time in total.

Bitcoin was and is a revelation.We've all learned so much from Bitcoin, both about what we formerly thought was technically impossible, and about what people value and care about.I sure hope so!We're engineering it for that!But, like Bitcoin, Zcash is an experiment in making something new that never existed before, and we can't know what the results of an experiment will be before we do it.After you posted that question, but before the AMA began, I posted this new blog post about it: https://z.cash/blog/funding.htmlThere will not be a crowd-sale or "initial coin offering".Let me know if that blog post answers your questions.shelby3 Nickel Bitcoiner Posts: 10 Joined: Sun Jan 31, 2016 5:01 pm Re: I'm Zooko Wilcox, CEO of the Zcash Company.In the short-term Atomic Cross Chain Swaps are already possible, and that's the chain-linking technology that I'm most excited about because it is already here.I am afraid you have not understood the horrific technical implications of sidechains.

I believe you do not yet understand well block chain consensus issues.I may be mistaken about what you do and don't know, but based on that you didn't admit that sidechains are fundamentally flawed, then this is troublesome.I am not trolling you. have analyzed this issue.I originally applauded sidechains until I understood all the technical implications that revolve around chain reorganizations.Last edited by shelby3 on Mon Feb 01, 2016 8:32 pm, edited 1 time in total.You asked a lot of questions.☺We're focused on launching the live, permanent, secure Zcash blockchain as soon as possible./Electric-Coin-Compan ... i-get-somePlease see my earlier reply in this thread.Maybe Zcash and Bitcoin can grow into each other in the future.Yay!First of all I'd ask you to join our community, educate others, facilitate constructive and friendly conversation./UPDATE: Whoops, that's the wrong link.( is cool too.)

UPDATE: I just posted a blog post describing the corporate structure and funding model: https://z.cash/blog/funding.htmlIt is quite unfortunate to read you've only raised $1 million in exchange for 11% of the coin supply.Ethereum raised several $millions and with my endorsement surely you could have raised well in excess of $1million for 10% of the coin supply in an ICO where the coins would be more widely and fairly distributed amongst many speculators who then promote your coin for free!And you would have avoided the FinCEN regulations that apparently will require all miners to register as MSBs because you are requiring the miners to transfer value to your foundation or corporation.Readers note IANAL so consult your own attorney.1: Zooko is rare name.I was on the cypherpunks mailing list, where we were inventing all kinds of ideas about how pseudonymity could protect people from the threat of coercion while still preserving reputation and accountability.I decided I'd try it out — practice what I preach — so I made up a completely arbitrary string "Zooko", chosen to be unique so that could kibo for it, and to be easy to pronounce.As soon as I started posting under that new pseudonym, I was insta-doxed by Adam Back, who wrote something like "Hey we haven't heard from Bryce in a couple of weeks, and now there's this new 'Zooko' person who writes just like Bryce did.".But

the next thing that I learned is that pseudonyms are sticky, because I started gaining positive reputation under that name so I couldn't bear to stop using it.Now everyone calls me that all the time.(Turnsout I was totally wrong about it being easy to pronounce.)21 million!See the blog post I just posted this morning: https://z.cash/blog/funding.htmlIn the current testnet it is unchanged from Bitcoin, but we plan to change it before launching the real blockchain.I'm planning to choose a memory-oriented Proof-of-Work, and a RAM-oriented one instead of GPU-oriented one, if we can find one that fits into all of our security and engineering requirements.A delightful idea would be to make it possible for cell-phones to be miners, so that a billion people all around the globe would have an equal ability to run a miner.There are a lot of reasons that might prove impossible, but it is worth thinking about!Thanks for the questions.I care deeply about personal privacy, personal and organizational security, and about the decentralization and sharing of power.At this critical stage of human history we need a permissive environment where we can perform many experiments and make different kinds of mistakes, and fortunately we have that, in the Internet.

The Internet has enabled many wonderful experiments.Bitcoin is one of the most wonderful of them.Zcash is another.I wrote more about this on my introductory blog post for the Zcash project: https://z.cash/blog/helloworld.htmlHaven't you seen the new laws coming (eventually in all Five Eyes countries I've heard from reliable sources) that will ban end-to-end encryption?Yes, I have.I have followed that kind of development pretty closely for a long time.Since the original "Crypto Wars" in the 1990's, in fact.In Zcash, the creator of each individual transaction gets complete control over who can view the contents of the transaction.This is accomplished by each transaction being individually encrypted by an encryption key known only to the creator and the recipient.There is no other mechanism by which any party can gain the ability to view the contents of transactions other than getting the decryption key from the creator or the recipient of the transaction, or from someone else who has previously received the decryption key.

This is a simple, implementable, secure, and understandable mechanism for controlling who can see what.We call it "selective transparency".Does that answer your question?Thank you for your questions!As you probably know, it is damned hard to predict how long it takes to finish software engineering work.It is, if anything, even harder with security and privacy engineering than with anything else.So, I'm probably wrong, but I think we'll have the real permanent blockchain ready to launch in July of this year.There is currently no way for the public to acquire Zcash before the launch.See also: https://z.cash/blog/funding.htmlI don't know yet.Write to your favorite exchange and ask them to support Zcash.☺ And tell me what they say.Yes, there will be exactly 21 million Zcash: https://z.cash/blog/funding.html zooko AMA Posts: 32 Joined: Mon Nov 02, 2015 6:56 pm Location: Boulder, Colorado, USA Re: I'm Zooko Wilcox, CEO of the Zcash Company.Pleased to meet you, SOF.What country do you live in?This seems to be a question about Bitcoin, rather than about my project, Zcash, but nonetheless I'm very interested to hear about it.
