A pencil-and-paper round of SHA The mining process Bitcoin mining is a key part of the security of the Bitcoin system. The idea is that Bitcoin miners group a bunch of Bitcoin transactions into a block, then repeatedly perform a cryptographic operation called hashing zillions of times until someone finds a special extremely rare hash value.

At this point, the block has been mined and becomes part of the Bitcoin block chain. The hashing task itself doesn't accomplish anything useful in itself, but because finding a successful block is so difficult, it ensures that no individual has the resources to take over the Bitcoin system. For more details on mining, see my Bitcoin mining article.

A cryptographic hash function takes a block of input data and creates a smaller, unpredictable output. The hash function is designed so there's no "short cut" to get the desired output - you just have to keep hashing blocks until you find one by brute force that works. For Bitcoin, the hash function is a function called SHA In Bitcoin, a successful hash is one that starts with enough zeros.

But Bitcoin is exponentially harder. Currently, a successful hash must start with approximately 17 zeros, so only one out of 1. In other words, finding a successful hash is harder than finding a particular grain of sand out of all the grains of sand on Earth. The following diagram shows a block in the Bitcoin blockchain along with its hash. The yellow bytes are hashed to generate the block hash.

In this case, the resulting hash starts with enough zeros so mining was successful. However, the hash will almost always be unsuccessful. In that case, the miner changes the nonce value or other block contents and tries again. One round of the SHA algorithm showing the 8 input blocks A-H, the processing steps, and the new blocks. The blue boxes mix up the values in non-linear ways that are hard to analyze cryptographically.

Since the algorithm uses several different functions, discovering an attack is harder. If you could figure out a mathematical shortcut to generate successful hashes, you could take over Bitcoin mining.

The Ma majority box looks at the bits of A, B, and C. For each position, if the majority of the bits are 0, it outputs 0. Otherwise it outputs 1. That is, for each position in A, B, and C, look at the number of 1 bits. If it is zero or one, output 0. If it is two or three, output 1. In other words, if the number of 1 bits is odd, the sum is 1; otherwise, it is 0. The three values in the sum are A rotated right by 2 bits, 13 bits, and 22 bits.

The Ch "choose" box chooses output bits based on the value of input E. If a bit of E is 1, the output bit is the corresponding bit of F. If a bit of E is 0, the output bit is the corresponding bit of G. In this way, the bits of F and G are shuffled together based on the value of E. The red boxes perform bit addition, generating new values for A and E. The input W t is based on the input data, slightly processed. This is where the input block gets fed into the algorithm.

The input K t is a constant defined for each round. The other values pass through unchanged, with the old A value becoming the new B value, the old B value becoming the new C value and so forth. Although each round of SHA doesn't change the data much, after 64 rounds the input data will be completely scrambled. I perform the first round of hashing to mine a block.

Completing this round took me 16 minutes, 45 seconds. To explain what's on the paper: I've written each block A through H in hex on a separate row and put the binary value below.

In the lower right, a bunch of terms are added together, corresponding to the first three red sum boxes. In the upper right, this sum is used to generate the new A value, and in the middle right, this sum is used to generate the new E value. These steps all correspond to the diagram and discussion above. I also manually performed another hash round, the last round to finish hashing the Bitcoin block.

In the image below, the hash result is highlighted in yellow. The zeroes in this hash show that it is a successful hash. Note that the zeroes are at the end of the hash. The reason is that Bitcoin inconveniently reverses all the bytes generated by SHA What this means for mining hardware Each step of SHA is very easy to implement in digital logic - simple Boolean operations and bit addition. If you've studied electronics, you can probably visualize the circuits already.

For this reason, custom ASIC chips can implement the SHA algorithm very efficiently in hardware, putting hundreds of rounds on a chip in parallel. Image from Zeptobars. CC BY 3. It stores different hash values into memory, and then combines them in unpredictable ways to get the final result. As a result, much more circuitry and memory is required for scrypt than for SHA hashes. You can see the impact by looking at mining hardware , which is thousands of times slower for scrypt Litecoin, etc than for SHA Bitcoin.

Conclusion The SHA algorithm is surprisingly simple, easy enough to do by hand. The elliptic curve algorithm for signing Bitcoin transactions would be very painful to do by hand since it has lots of multiplication of byte integers.

Doing one round of SHA by hand took me 16 minutes, 45 seconds. At this rate, hashing a full Bitcoin block rounds [3] would take 1. In comparison, current Bitcoin mining hardware does several terahashes per second, about a quintillion times faster than my manual hashing.

Needless to say, manual Bitcoin mining is not at all practical. The next question is the energy cost. Thus my energy cost per hash is about 67 quadrillion times that of mining hardware. It's clear I'm not going to make my fortune off manual mining, and I haven't even included the cost of all the paper and pencils I'll need.

Follow me on Twitter to find out about my latest blog posts. The NSA designed the SHA algorithm and picked the values for these constants, so how do you know they didn't pick special values that let them break the hash? To avoid suspicion, the initial hash values come from the square roots of the first 8 primes, and the K t values come from the cube roots of the first 64 primes.

Since these constants come from a simple formula, you can trust that the NSA didn't do anything shady at least with the constants. Thus, a second set of 64 SHA hash rounds is required on the second half of the Bitcoin block. Adding this up, hashing an arbitrary Bitcoin block takes rounds in total.

However there is a shortcut. Mining involves hashing the same block over and over, just changing the nonce which appears in the second half of the block. Thus, mining can reuse the result of hashing the first bits, and hashing a Bitcoin block typically only requires rounds. I started the hashing process with a block that had already been successfully mined. In particular I used the one displayed earlier in this article, Email This BlogThis!

You're insane, but amazing. This is fantastic. You may have a typo in the Ma majority box description. The first sentence says "looks at the bits of A, B, and C", which agrees with the diagram. But the fourth sentence says "for each position in B, C, and D". Very cool but I'm a bit confused.

The diagram shown says "transaction count: 63" but the block on Block Explorer says "Transactions: 99". Why the discrepancy? Ignore the miserable buggers who are members of Anonymous Thank you. It looks pretty instructional. I shall go through it in detail in a bit. I love you, this is so nerdy, so geeky but so fantastic. I love how you calculated energy costs lol. Your endeavor makes me think about my blog page where I showed a picture for my description "The early Bitcoin miner was very efficient on electricity, however zero Bitcoin yield.

I am tempted to add you to my "Bitcoin Mining Rigs". Thanks Ken. That was really funny. Now I think you are even more similar to Weird Al. And I also know what you do on Fridays when soccer season is not on.

We look at six blockchain start-ups developing a variety of different technologies for security solutions, banking and offsetting negative environmental impacts. Of the Technology Pioneers that were selected by the World Economic Forum WEF this year, as part of its annual programme that brings cutting-edge insight to critical global discussions, six of those start-ups were focused on blockchain and distributed ledger technology DLT. This week, we take a look at those six blockchain and DLT start-ups in more detail. We're thrilled to share that Google is one of the great companies integrating Chainlink into their approach to smart contract adoption. The start-up has developed a decentralised network that enables smart contracts to securely access off-chain data feeds, web application programming interfaces and traditional bank payments. The start-up was founded with the belief that illicit activity in cryptocurrencies must be disrupted to stop criminals from undermining the ideals on which cryptocurrencies are built.
