Before you read further, please understand that most bitcoin users don't mine! But if you do then this is probably the best deal. Bitcoin mining for profit is very competitive and volatility in the makes it difficult to realize monetary gains without also speculating on the price. Mining makes sense if you plan to do it for fun, to learn or to support the security of Bitcoin and do not care if you make a profit. If you have access to large amounts of cheap electricity and the ability to manage a large installation and business, you can mine for a profit. If you want to get bitcoins based on a fixed amount of mining power, but you don't want to run the actual hardware yourself, you can purchase a mining contract. Another tool many people like to buy is a which enables people to load a debit card with funds via bitcoins. What is Bitcoin mining? Bitcoin mining is a lot like a giant lottery where you compete with your mining hardware with everyone on the network to earn bitcoins. Faster Bitcoin mining hardware is able to attempt more tries per second to win this lottery while the Bitcoin network itself adjusts roughly every two weeks to keep the rate of finding a winning block hash to every ten minutes. In the big picture, Bitcoin mining secures transactions that are recorded in Bitcon's public ledger, the block chain. By conducting a random lottery where electricity and specialized equipment are the price of admission, the cost to disrupt the Bitcoin network scales with the amount of hashing power that is being spent by all mining participants. Technical Background During mining, your Bitcoin mining hardware runs a (two rounds of SHA256) on what is called a. ![]() For each new hash that is tried, the mining software will use a different number as the random element of the block header, this number is called the nonce. Depending on the nonce and what else is in the block the hashing function will yield a hash which looks something like this: 93ef6f358fbb9d4c63735b7fe5bdaac821de96a53a9a You can look at this hash as a really long number. (It's a hexadecimal number, meaning the letters A-F are the digits 10-15.) To ensure that blocks are found roughly every ten minutes, there is what's called a difficulty target. To create a valid block your miner has to find a hash that is below the difficulty target. So if for example the difficulty target is 0000 any number that starts with a zero would be below the target, e.g.: 0787a6fd6e0782f7f8058fbef45f5c17fe89086ad4e78a1520d06505acb4522f If we lower the target to 0000 we now need two zeros in the beginning to be under it: 00db27957bd0ba06a5af9e6c2a7028cf9a08fa125e49f15cae4979 Because the target is such an unwieldy number with tons of digits, people generally use a simpler number to express the current target. This number is called the mining difficulty. The mining difficulty expresses how much harder the current block is to generate compared to the first block. So a difficulty of 70000 means to generate the current block you have to do 70000 times more work than had to do generating the first block. To be fair, back then mining hardware and algorithms were a lot slower and less optimized. To keep blocks coming roughly every 10 minutes, the difficulty is adjusted using a shared formula every 2016 blocks. The network tries to change it such that 2016 blocks at the current global network processing power take about 14 days. That's why, when the network power rises, the difficulty rises as well. Bitcoin Mining Hardware CPU In the beginning, mining with a CPU was the only way to mine bitcoins and was done using the original Satoshi client. In the quest to further secure the network and earn more bitcoins, miners innovated on many fronts and for years now, CPU mining has been relatively futile. You might mine for decades using your laptop without earning a single coin. GPU About a year and a half after the network started, it was discovered that high end graphics cards were much more efficient at bitcoin mining and the landscape changed. CPU bitcoin mining gave way to the GPU (Graphical Processing Unit). The massively parallel nature of some GPUs allowed for a 50x to 100x increase in bitcoin mining power while using far less power per unit of work. While any modern GPU can be used to mine, the AMD line of GPU architecture turned out to be far superior to the nVidia architecture for mining bitcoins and the ATI Radeon HD 5870 turned out to be the most cost effective choice at the time. FPGA As with the CPU to GPU transition, the bitcoin mining world progressed up the technology food chain to the Field Programmable Gate Array. With the successful launch of the Butterfly Labs FPGA 'Single', the bitcoin mining hardware landscape gave way to specially manufactured hardware dedicated to mining bitcoins. While the FPGAs didn't enjoy a 50x - 100x increase in mining speed as was seen with the transition from CPUs to GPUs, they provided a benefit through power efficiency and ease of use. A typical 600 MH/s graphics card consumed upwards of 400w of power, whereas a typical FPGA mining device would provide a hashrate of 826 MH/s at 80w of power. That 5x improvement allowed the first large bitcoin mining farms to be constructed at an operational profit. The bitcoin mining industry was born. ASIC The bitcoin mining world is now solidly in the Application Specific Integrated Circuit (ASIC) era. An ASIC is a chip designed specifically to do one thing and one thing only. Unlike FPGAs, an ASIC cannot be repurposed to perform other tasks. An ASIC designed to mine bitcoins can only mine bitcoins and will only ever mine bitcoins. The inflexibility of an ASIC is offset by the fact that it offers a 100x increase in hashing power while reducing power consumption compared to all the previous technologies. Unlike all the previous generations of hardware preceding ASIC, ASIC may be the 'end of the line' when it comes to disruptive mining technology. CPUs were replaced by GPUs which were in turn replaced by FPGAs which were replaced by ASICs. There is nothing to replace ASICs now or even in the immediate future. There will be stepwise refinement of the ASIC products and increases in efficiency, but nothing will offer the 50x to 100x increase in hashing power or 7x reduction in power usage that moves from previous technologies offered. This makes power consumption on an ASIC device the single most important factor of any ASIC product, as the expected useful lifetime of an ASIC mining device is longer than the entire history of bitcoin mining. It is conceivable that an ASIC device purchased today would still be mining in two years if the device is power efficient enough and the cost of electricity does not exceed it's output. Mining profitability is also dictated by the exchange rate, but under all circumstances the more power efficient the mining device, the more profitable it is. If you want to try your luck at bitcoin mining then this is probably the best deal. Bitcoin Mining Software There are two basic ways to mine: On your own or as part of a Bitcoin mining pool or with and be sure to. Almost all miners choose to mine in a pool because it smooths out the luck inherent in the Bitcoin mining process. Before you join a pool, make sure you have a so you have a place to store your bitcoins. Next you will need to join a mining pool and set your miner(s) to connect to that pool. With pool mining, the profit from each block any pool member generates is divided up among the members of the pool according to the amount of hashes they contributed. How much bandwidth does Bitcoin mining take? If you are using a for mining with a pool then the amount should be negligible with about 10MB/day. However, what you do need is exceptional connectivity so that you get any updates on the work as fast as possible. This gives the pool members a more frequent, steady payout (this is called reducing your variance), but your payout(s) can be decreased by whatever fee the pool might charge. Solo mining will give you large, infrequent payouts and pooled mining will give you small, frequent payouts, but both add up to the same amount if you're using a zero fee pool in the long-term. Bitcoin Cloud Mining By purchasing Bitcoin cloud mining contracts, investors can earn Bitcoins without dealing with the hassles of mining hardware, software, electricity, bandwidth or other offline issues. Being listed in this section is NOT an endorsement of these services and is to serve merely as a Bitcoin cloud mining comparison. There have been a tremendous amount of Bitcoin cloud mining scams.: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s.: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider. Genesis Mining offers three Bitcoin cloud mining plans that are reasonably priced. Zcash mining contracts are also available.: Hashing24 has been involved with Bitcoin mining since 2012. They have facilities in Iceland and Georgia. They use modern ASIC chips from BitFury deliver the maximum performance and efficiency possible. What is Bitcoin Mining? Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a 'subsidy' of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground. What is Proof of Work? A is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements. Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work. What is Bitcoin Mining Difficulty? The Computationally-Difficult Problem Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information. The Bitcoin Network Difficulty Metric The is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes. As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless. The Block Reward When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply or use a. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

The problem with a static analysis is that network hashing power does NOT stay the same. Now the ethereum calculator gets the latest network hash rate from etherchain. Because the network hashing power has historically gone cliud and gone up A LOT. Factoring in the growth rate of block difficulty is the most important factor when determining cloud mining profitability. Hashrate and Blocktime calculated by looking at the last 64 blocks. Calculation is based on the following formula: You need to make a realistic estimate of how the network hashrate will increase because it will reduce the amount you get from mining each day. The chart above cloud mining calculator eth eur the Ethereum network hashrate growth. In this example, Hashflare. So we need a realistic estimate of how much the hashing power and thus mining difficulty will go up over a 12 month period. Use one eth mining eur cloud calculator second reason This takes some guesswork eurr the best indicator is the past. This was the first 12 months of the Ethereum network coming online so I think this number is too high. So then we follow step 1 again using the static calculator. The monthly ETH mined would be 0. These are just a projections based on calculstor static analysis and a guesstimate of where mining difficulty will be in the future. The amount calcklator is slowly and steadily decreasing. I think a exponential decay model fits the data better but for the sake of ease I think a linear model will suffice. Subtract the first from the last. Note that calculator floud eur mining eth coinbase UTXO Then divide that by From that point you take the starting value of. Evaluated the eth mining cloud eur calculator you might You do this again until you get cxlculator month If Network Calculato Power Goes Up You Start to Lose So what I hope this shows is that if the hashing power goes up, which in kining case of Ethereum and I suspect most coins as well the amount of coins mined will drop and the profits will be eroded. Easy Method If you believe network hashing power continue to go up then use this method to determine if mining is even worth a closer evaluation: That would yield 0. Then buy ETH directly. It goes from At what price would cloud mining be worth it? Given calcculator risk and volatility in cryptocurrencies I would need to see that kind of return for it to be worth the risk to me.

Mining pools. To offset the difficulty of mining a block, miners started organizing in pools or cloud mining networks. Bitcoin; Ethereum; Other Public. You need to calculate an equivalent cost per kilowatt hour to feed into the mining calculator. How Does Cloud Mining Bitcoin Work? Is Ethereum Mining Profitable? As the price of hovers around $300, you may be wondering to yourself whether or not it’s worthwhile to begin mining. Like Bitcoin, Ethereum is a proof-of-work coin that uses miners to confirm network transactions. The profitability of mining varies from person to person and changes over time – usually becoming less profitable as the coin matures. There are three important factors to consider when figuring out if Ethereum mining will be profitable for you: • Mining difficulty • Hash rate • Electrical costs Mining difficulty Putting it simply, your mining rig needs to solve a mathematical algorithm to mine Ethereum. The mining difficulty of the network is a measurement of how difficult this algorithm is to solve. The higher the difficulty, the less Ethereum you receive for each unit of energy the GPU on your mining rig expends. ![]() As more miners join the network, this difficulty increases. The Ethereum mining difficulty had been steadily increasing since July but recently dropped from a high of ~3,000T to ~1,500T. This dip was caused by the Byzantine fork but isn’t as advantageous as it seems. Even though the difficulty decreased, the block reward also decreased from 5 ETH to 3 ETH effectively canceling out any benefit from the difficulty change. You can view the past and current difficulty on the Ethereum network. Hash rate The hash rate is the speed in which your mining rig can solve the mathematical algorithm needed to validate a transaction. New miners are constantly entering the market with better and faster hash rates. There’s more to buying a miner than just picking the one with the highest hash rate, though. Miners with a high hash rate usually come with a high price tag. On top of that, they also typically use more electricity as they operate which could further drive your costs up. Electrical costs Each mining rig operates at a different level of efficiency and uses a variable amount of electricity. On the low end, miners typically draw ~100 W at their maximum load, but this can increase up to over 1000 W with more powerful and less efficient miners. With the amount of mining variation, you’ll want to calculate your power cost per day and compare that to the estimated return per day when picking out a miner. You can use to calculate what your estimated profits would be using different Ethereum miners. The move towards proof-of-stake Vitalik Buterin, the creator of Ethereum, announced earlier this year that the Ethereum network is going to switch from a proof-of-work to a framework to confirm transactions. With a proof-of-stake system, holders of Ethereum stake coins by putting them up as collateral to validate transactions. This means that miners will soon be obsolete. With the current saturation of miners and the stated plans to switch the network to a proof-of-stake system, I would avoid mining Ethereum at this time. There are several other coins available for mining, like, that may be a better choice for you depending on your goals. If you do decide to mine Ethereum, you’ll also want to join an.

Is quite difficult to get mining on windows - although with a bit of help and following the tutorial below you can get it up and running and start your own ethereum mining project in 15 mins. We're going to show you how to start mining on your GPU and CPU with Windows 64 bit in this guide. You will need to download two programs and need to have a decent GPU with more than 1GB of memory to get the most bang for your buck in terms of mining as Ethereum works on a memory hard hashing technique which GPU's are best. You can also mine if you start your geth in Step 7 with the param --oppose-dao-fork.. Running a CPU you might be able to generate 0.15 Mega Hashes whilst with a decent GPU with enough memory you could be doing upwards 25 Mega Hashes ( and use our guide on ). So in terms of total efficiency, taking into account electrical costs, a GPU is definitely worth it even if it costs you $200. You can also try buying a cloud mining contract with. Part 1 - Installing GETH, Syncing the Blockchain & creating your own address! Step 1: The first thing you need to do is go to this link. Geth is the program that communicates with the Ethereum Network and acts as the a relay between your computer, its hardware and the rest of the ethereum network computers so if a block is mined by another computer your Geth program will pick it up and then pass on the new information onto your GPU or CPU for mining. Step 2: You need to unzip the GETH file and move it to a location on your hard drive. In this case we'll move it to the hard drive, usually ( C:) - which will make the next step easier. All you need to do is copy the file you have downloaded and unzipped and move it to the hard drive folder. Step 3:Now you need to run the program you just downloaded. To do this you need to run Command Prompt. You can do this by searching in the search function in Windows for ' CMD' and then clicking on it when it shows up. Step 4: Command Prompt is now open - and can look terrifying to people who aren't familiar with it. The Command Prompt box usually has C: Users Username> showing in it - where Username is your username - so if you log into your computer with the username cryptocompare then the command prompt box will open with C: Users cryptocompare. You need to tell the computer to look in another place Type cd / into the newly opened command prompt. You should now see ' C: >', You have just used the cd command or ' change directory' command to make command prompt look at the C:/ drive. Step 5: You need to tell your Geth program to create a new account. As you have installed it in your user directory in Step 2 then it is just a simple case of typing in ' geth account new' and then pressing return/enter. This should look like this ' C: >geth account new'. Step 6: After hitting the enter button in Step 5, you will be asked to enter a password - N.B. You will not be able to see what you are typing in so type it carefully. This is the password that locks your account and keeps your Private key safe - if you lose this password you will lose all your Ether attached to the wallet held by that Private key. Once you have entered your password and confirmed it by entering it a second time you will have created a new account! Congratulations your about a third of the way there. Step 7: You need to tell your Geth Program to start communicating with the rest of the Ethereum network. You do this by typing in ' geth --rpc' - this should look like ' C: >geth --rpc' (on the latest version you should try: geth --rpc --fast --cache=1024) Press enter and the screen should start downloading the blockchain for Ethereum - at this point you are synchronising with the rest of the Ethereum network. This can take a while depending on your internet speed and the current size of the blockchain, anywhere between 20 min and multiple hours. Sometimes your firewall can block this process - just click allow access. Keep this cmd open, you will need this to run in the background in order to be able to mine. Also make sure you start mining only after your blockchain is synchronised, not before. Due to The DAO hard fork you will have to specify if you want to mine on the hard fork chain or on the chain without the hard fork. To mine use geth --rpc --support-dao-fork in order to mine use: geth --rpc --oppose-dao-fork Part 2 - Installing the Mining Software and Starting to Mine Step 8: Now you need to which makes your GPU or CPU run the hashing algorithm that is integral to securing the Ethereum network through proof of work. You can download this here and be sure to scroll down to the bottom of the page to get the right version - the latest and most up to date one is right at the end. Step 9: Click on the download and click install. Your firewall can cause issues but just click allow if it does so - the same is true of windows that doesn't recognise or approve the software - tell windows its ok when asked. Click through the installation process until Ethminer is installed. Step 10: You need to open up another command prompt as in step 4 - so your going to get two scary looking boxes. Simply click right click on your already open command prompt in the taskbar at the bottom of the page and click on command prompt in the menu that appears. A new command prompt should open with ' C: users username>'. This is the wrong place to look for etherminer so you need to tell it the right place to find it. Step 11: Type ' cd /' into the newly opened command prompt which should look like this ' C: users username>cd /' and then press enter. You should now see 'C: >', You have just used the 'cd' command or 'change directory' command to make command prompt look at the C:/ drive - not your user file. Step 12: Type in ' cd prog' and then press the tab button. This should look like this C: >cd prog and then press 'tab' which will automatically complete the phrase for the closest fit found in the C: drive just like autotext does on your Iphone. After pressing 'tab', you should see C:/> cd 'Program Files' and press enter which should give you a new line saying 'C: Program Files>'. Step 13: Type in cd cpp and then press tab and then enter. This is taking you into the newly installed Ethereum Mining software folder. And this should look like this after pressing tab C: Program Files>cd cpp-ethereum and pressing enter gives you C: Program Files cpp-ethereum. Step 14 GPU mining ( only do this after your blockchain is synchronised): Type in ethminer -G and press enter and then you should start mining with your GPU after building a DAG file which can take around ten minutes. There can be problems at this point. For example the program might say that you have insufficient memory on your Graphics card to mine the with Ethereum's Ethash algorithm. If this is the case you can still mine with your CPU or go out and buy a new graphics card! You can see and. We've also added a guide on. If you get an error message press Ctrl and c together to cancel the process. Then you can either retry it - or alternatively move onto step 16 and mine with your CPU rather than your GPU. Step 15 CPU mining: Type in ethminer and press 'enter' and you will start mining with your CPU. Again you will need to create a DAG file the first time you do this which can take some time. But after that is complete your Geth program downloaded in step 1 should start talking to your ethminer program and you should start mining! Step 16 Hashing Power benchmark: If you want to get an estimation of your hashing power you can run ethminer -M (for CPU mining) or ethminer -G -M ( for GPU mining). The command will run and you should get a result similar to the image bellow. Step 15 and 16 possible error: If you are not patient is ' JSON-RPC problem. Probably couldn't connect. Retrying in 1.' As you can see in the screenshot bellow this happens when you don't have the blockchain synced yet. FAQ: If you are having issues getting your GPU to mine type ethminer --opencl-platform 1 to fix it for Nvidia. This usually happens when you have an integrated GPU as well as a dedicated one. If you are having issues finding peers, try to use: geth --nat=none If you are using ATI cards, in order to optimize your mining open a cmd prompt and run: setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 Also when you run ethminer, try using the extra params: --cl-global-work 16834 --cl-local-work 256 Good luck and if there are any problems type a comment in at the bottom of this article and the community will help you get started!

Also now that you are happily mining visit our Ethereum page if you want too keep up to date with the. Even if the craze for Bitcoin and Ethereum abates, the power of the “blockchain” tech behind those currencies is very real. Here’s how businesses are trying to harness it—and why they can’t afford to ignore it. One summer morning in a coffee shop on Atlantic Avenue in Brooklyn, I sit behind my MacBook Pro as tens of thousands of machines around the globe prepare to indelibly inscribe a record of my tinkering into their collective consciousness. I am in the midst of creating my own digital tokens—essentially online currency—on a sprawling, decentralized network known as Ethereum. Mike Goldin, a software developer at ConsenSys, an Ethereum development studio based in Bushwick, walks me through the coding process. Goldin is my Sherpa today, graciously attending, with utmost patience, to my every query. (The 10-plus hours I spent downloading software the day prior was unnecessary, he tells me; we’re going to employ some work-arounds that will achieve my goal in a matter of minutes.). After considering a variety of names for my token—“fortunecoin,” “hackettoken,” “neither”—I settle on a cheeky one that evokes a spectacular flameout of the great ’90s Internet bubble: “Petsdotcoin.” I click “create.” Transaction hash 0xc14d13893bd0f0ff997a8a701c0c8844661a6ddb921a42f2f61c8c7adb0d158c (Pending) (Pending) (Pending) Twenty-seven seconds and one block confirmation later, I am the proud owner of 500 newly minted “petsdotcoin” tokens. Their creation cost me $1.57 in Ether, the cryptocurrency that fuels the Ethereum network. Despite that expense, my tokens are valued at 0 Ether, or $0.00, as the program reminds me. They are worthless. But if I had tied those bits to some worthwhile business idea, petsdotcoin might have offered investors a radical new way to fund me, track their stake, and participate in a miniature, virtualized, in-app economy. In that respect, my funny-money vanity project is a tiny part of a movement of profound economic significance. In case you haven’t been keeping track, digital tokens are a new asset class, powered by cryptocurrency networks like Bitcoin and Ethereum. The sector has attracted maniacal investor interest this year, giving these e-coins absurdly inflated valuations that have inspired endless. (Hence, petsdotcoin.) At press time, the total market value of all virtual currencies had rocketed past $135 billion, up from just under $20 billion at the beginning of the year. Hundreds of projects have collectively raised more than a billion dollars through “” (ICOs). ![]() There are now tokens funding every conceivable endeavor: Decentralized cloud storage (FileCoin, Storj). Digital advertising (Basic Attention Token, adToken). A gentlemen’s club in Las Vegas (Legends Room). Marijuana (Potcoin). Satire (PonzICO). There’s even one for dentists (DentaCoin). Aug 22, 2017 - Scores of companies are adapting and advancing the core technology to suit their needs. While some are exploring digital currency and the open-source, free-for-all ecosystem of public blockchains (of which Bitcoin and Ethereum are prime examples), far more are concentrating on how the technology. The other reason I call Genesis a scam is that, having done the cloud mining contract with them, I noticed sharp, severe, and consistent drops in the rate of payouts that did not correspond at all with. With Hashflare's news of ending all life time contracts next year, seems like Genesis is taking advantage. In a photo recently posted to Instagram,, the boxer, sits on a private jet surrounded by stacks of dollar bills, touting the sale of tokens for a prediction market called Stox—a moment some saw as proof that ICO hype had reached peak zaniness. A post shared by (@floydmayweather) on Jul 27, 2017 at 11:46am PDT The smart money is also playing in this pool. Established venture capital firms like Sequoia, Andreessen Horowitz, and Union Square Ventures are of dollars into. The topic is all the rage on Wall Street. But notably, the long-betting investors in this space see today’s numismatic delirium as a distraction. “Right now it’s much easier to get more focused on the short-term ICO money stuff,” says Chris Dixon, a general partner at Andreessen Horowitz. “I think this unfortunately overshadows the more important technology story.”. That story goes like this: Underneath the crypto-hysteria is a grand innovation in the humble realm of accounting. The most bullish acolytes of this electronic book-balancing breakthrough, Dixon included, hold that token-based projects will anchor the web’s next revolution, spawning crowdfunded businesses and services that deliver more value to their users while being less dependent on advertisers or rent-seeking middlemen., meet Tokenbook. Look beyond the, and you can glimpse another paradigmatic shift inspired by that same accounting innovation. Incumbent businesses in countless industries, from finance to energy to health care to food, are peeling back the layers on this budding technology, seeing the potential to trim costs, share and secure information more efficiently, and unleash new products at unprecedented speed. And they’re doing so knowing that one day their survival may be at stake: Having witnessed what the advent of digital, cloud, and mobile did to laggard companies, no one wants to be the sucker left behind. The technology in question: that choreographic marvel called a blockchain. No term at present is more hyped, and more poorly understood. During a discussion at Fortune’s Brainstorm Tech conference this summer,, a London-based cryptocurrency wallet provider, half-jokingly defined “blockchain” as a marketing term exploited by salespeople to ink deals. A less cynical definition might go as follows: A blockchain is a kind of ledger, a table that businesses use to track credits and debits. But it’s not just any run-of-the-mill financial database. One of a blockchain’s distinguishing features is that it concatenates (or “chains”) cryptographically verified transactions into sequences of lists (or “blocks”). The system uses complex mathematical functions to arrive at a definitive record of who owns what, when. Properly applied, a blockchain can help assure data integrity, maintain auditable records, and even, in its latest iterations, render financial contracts into programmable software. It’s a ledger, but on the bleeding edge. Blockchain boosters say its development is one that rivals, in significance, the invention of double-entry bookkeeping. That’s the revolutionary method of tabulating assets and liabilities that emerged in Renaissance Italy and that, according to some historians, put wind in the sails of capitalism, allowing investors and entrepreneurs to team up in corporations and launch merchant ships beyond the horizon in search of commercial success. Blockchains, in this analogy, are triple-entry bookkeeping, where the third entry is a verifiable cryptographic receipt of any transaction. Photo: C-SPAN Perhaps most spectacularly, a blockchain can get rivals to cooperate in creating a common record that is accessible to everyone and controlled by no one. This was the genius of Satoshi Nakamoto, the alias for the as-yet-unidentified creator (or creators) of the first blockchain, Bitcoin, which debuted in 2009. (Since then, the value of a single Bitcoin has reach a high of.) Part of Bitcoin’s secret sauce is its consensus mechanism, which allows people to agree on a canonical order of transactions, thereby preventing double-spending and fraud, through a combination of cryptography and economic incentives based on game theory—all without needing a third party or middleman, like a bank. Even if participants don’t trust one another, they can rely on the shared ledger they create through the transactional dance of their software. You don’t need honor among thieves—you just need a blockchain. See also: If Bitcoin proved what was possible, Ethereum, a rival system, took its ingenuity to a logical extreme., a twentysomething Russia-born programmer ( on Fortune’s 40 Under 40 list this year), created a blockchain that aims to be anything to anyone: His Ethereum can create representations of any asset, which has made it the primary fuel of the digital-token boom. But by showcasing blockchain’s fundamental flexibility, Ethereum’s rise has also accelerated a deluge of research and development in corporate America. Scores of companies are adapting and advancing the core technology to suit their needs. While some are exploring digital currency and the open-source, free-for-all ecosystem of public blockchains (of which Bitcoin and Ethereum are prime examples), far more are concentrating on how the technology underpinning those systems can add value to their businesses—by helping them with everything from corralling medical records to tracking the provenance of a pork loin. Many are concocting “permissioned” or “private” blockchains, designed for a more centralized architecture where only authorized operators can join. See the full Fortune 2017 list here. To some stalwarts, this corporate appropriation runs counter to the original, idealized blockchain as introduced by Nakamoto. “The word was hijacked to sell enterprise software, basically,” says Olaf Carlson-Wee, founder of Polychain Capital, perhaps the most high-profile of the cryptocurrency hedge funds. Some entrepreneurs, like Chain CEO Adam Ludwin, argue that new ledger technology isn’t really a blockchain if the items it tracks aren’t financial., a New York–based consortium of financial firms that began as a blockchain startup, now avoids the word, calling itself a “distributed ledger technology” company. But this schism over terminology isn’t hampering the science. Ultimately, anyone working on next-generation data structures with cryptographic signatures and joint-stakeholder elements might now be said to fall under the “blockchain” umbrella. “It’s entered the vernacular like Kleenex,” says Matt Higginson, partner in McKinsey’s global banking practice. And whatever you want to call it, more and more businesses are gathering there. One day last December, Frank Yiannas went to a store near company headquarters in Fayetteville, Ark., and picked up a package of sliced mangoes. Yiannas is Walmart’s vice president of food safety, and the fruit was part of a crucial experiment. He brought the mangoes back to his office, placed the container on a conference table, and gave his team a mission. “Find out where those mangoes came from,” he ordered, setting a timer. It took six days, 18 hours, and 26 minutes to get an answer. That’s better than the weeks it can sometimes take companies, Yiannas says. Still, a near-week is a long time. In the event of an outbreak of foodborne illness—one in which a suspected pathogen is tied to mangoes somewhere—a lag that long could be painfully costly. By that point, Walmart might have had to pull every package of every mango product off its shelves, as a precaution; farmers, distributors, and Walmart itself would take the hit. A few months after the fact, Yiannas repeats a version of the IBM demo for me. He enters a six-digit “lot” number on a web portal. In an instant, the mangoes’ identifying details appear on-screen: Mango spears, 10 ounces, “Tommy” variety (a cultivar optimized for transport). The fruit was harvested April 24 from orchards in Oaxaca, in southern Mexico. A day later, the fruit underwent hot-water treatment to exterminate the eggs of potentially invasive insects. On April 27, an importer received the shipment; after a few more days, it passed through Customs and Border Protection, entering a U.S. Processing plant where they were sliced on May 1. From there, the mangoes moved to a cold storage facility in Los Angeles (you can pull up a safety inspection certificate with a click of a mouse). Finally, the lot arrived at a Walmart store. The time it took to compile and present all this information: about two seconds. (It clocked a similar time when Yiannas demonstrated it at Walmart’s annual shareholder meeting this summer.) In the event of an E. Coli or salmonella outbreak, the difference between two seconds and six-plus days can be decisive, even lifesaving. But in the context of a supply chain, a blockchain is far more than an emergency measure: The granular, secure records in the system could help prevent fraud, and provide an easy-to-use interface for executives to keep tabs on the flow of goods, as well as for regulators to peek under the hood when necessary. “This was not about chasing the shiny coin,” Yiannas says. “There were business challenges we were trying to solve.”. For more, read “.” Other companies are now exploring blockchains’ potential for their logistics. Maersk, the Danish shipping giant, has started testing a blockchain to track its shipments and coordinate with customs officials. Airbus, the French aircraft maker, is looking to use blockchains to monitor the many complex parts that come together to make a jet plane. Daimler, the German automaker, is investigating similar possibilities for its vehicles. The potential doesn’t stop with tangible goods like windshield wipers or watermelons: Many companies and governments think blockchains could help them assemble tamper-resistant systems for storing virtually any kind of data. BAE Systems, the British defense contractor, is exploring sharing cybersecurity threat data on a blockchain. Pokitdok and Gem are looking to revamp electronic medical record management. And Accenture has teamed up with and a United Nations group to build a blockchain for digital identity, especially useful for refugees who lack official documents. Even with all these potential applications, there’s arguably no industry where the promise of blockchain tech—or its peril—is more apparent than in finance. Taped up to a glass dry-erase board behind ’s desk is an unassuming sketch. It displays the black outline of four circles, four rectangles, a few conjoining lines, and a few acronyms of academic institutions such as SRI, UTAH, and UCLA. The image is an early depiction of Arpanet, the forerunner of today’s Internet. Baldet, who heads up the blockchain group at (and is on our 40 Under 40 list), views her work as very much in a similar phase of development. For enterprises, she says, it’s 1969, and they’re tinkering with a technology that could, in time, be as important as the Internet. For more, read “.” Finance is the most obvious extension of blockchain tech, given the monetary roots of Bitcoin. Trade finance, security clearance and settlements, cross-border payments, and insurance are all areas that could be overhauled and made more seamless. Microsoft is collaborating with on a blockchain to digitize and automate the money flow around trades. HSBC, ING, U.S. Bank, and eight other banks recently completed a prototype application for the same purpose on R3’s Corda ledger. Northern Trust, the asset management firm, is using Hyperledger Fabric for private-equity deal record keeping. And Ripple built a system to rival the SWIFT interbank money-transferring service. In a hotly competitive sector where customers demand faster transactions and lower costs, the rewards of building the best blockchain mousetrap could be vast—the penalties for missing out, proportionately painful. Photo: Benjamin Spradley To help stake J.P. Morgan’s claim, Baldet’s team has created a so-called permissioned variant of the Ethereum blockchain. The bank open-sourced the code late last year, under a “general public license” that allows anyone to draw from or contribute to the design. This retooled blockchain, dubbed Quorum, is the first software ever released by J.P. Morgan this way. It’s an unusual move by the bank, which certainly had the resources to work in-house and in secret. Morgan sees a benefit to rallying all parties to work on a common platform that could reduce costs. “We spend a whole lot of money trying to transact with our counterparties and our clients,” Baldet explained at a recent MIT Technology Review event in Cambridge, Mass. “The more free that sort of thing is, the better for us.”. Morgan team is already breaking ground—and, in the process, underscoring key differences between private and public blockchains. In March, Quorum began adding support for “zero knowledge proofs,” advanced cryptography commercialized by the Zerocoin Electric Coin Co., makers of the Zcash cryptocurrency. That cryptography enables state-of-the-art privacy features—something the Ethereum Foundation, the Swiss nonprofit that maintains the public Ethereum blockchain, has yet to do, though it plans to. Morgan, after all, is designing Quorum to prioritize the needs of corporations, especially in data confidentiality and scalability—areas where private blockchains excel and, for now, public blockchains struggle. Still, many industry insiders believe that public and private will eventually intersect—just as internal networks came to coexist with and feed the public Internet decades ago. “I think we’re going to see the distinction between public chain and private chain eradicated in the next two to three years,” says Jeremy Millar, chief of staff at, and a founding board member of the Enterprise Ethereum Alliance, a group of financial and tech firms that includes J.P. Morgan and is pushing Ethereum-based. “We’ll be talking about global chains vs. Industry and company chains.”. Photo: Manuel Romano—NurPhoto via Getty Images At a recent blockchain event hosted by Microsoft in Manhattan, I ask a group of executives whether they’re similarly bullish. The responses span the gamut from “absolutely” to “I have no idea.” Patrick Nielsen, lead engineer of Quorum, overhears my line of questioning. He can barely conceal his amusement beneath an impressively leonine beard. We’ve got some academic institutions and military research agencies, he says with a wry smile, referencing the topology of the Internet in its early days. “Just have to add a few more nodes to the network.”. Granted, there are many technical and cultural challenges standing between that vision and reality.
