An Advisor’s Guide to Bitcoin Hash Rates and Mining


More investors and advisers are showing interest in the crypto economy, and most advisers have reported that their customers have asked them about crypto in the last year. Cryptocurrencies can be confusing at first glance, especially the Bitcoin network. The following is a basic explanation of how the Bitcoin network works and the role that crypto miners have within it, as reported by Bitcoin Magazine.

Bitcoin uses a Secure Hash Algorithm (SHA), the origin of which was created by the NSA, as a way to encrypt information. The Bitcoin network uses a specific algorithm, SHA256, which is the essential tool used to encrypt data in an extremely complex yet methodical way. The way SHA256 works is that any type of digital data is entered; It is important to note that this process is very precise and any change to the original input will result in a very different output, and is then run through the SHA function. to achieve a unique output, called a hash.

It’s impossible to determine the input just by looking at the output, but the result will always be identical if the input is the same and SHA256 is used, no matter where in the world or what kind of computer is calculating the hash. The number that comes out is 256 numbers in binary, but is often abbreviated to hexadecimal form.

No matter how long the original input is, the output will always be the same length, and it is always impossible to predict the output by inputting the input; this can only be calculated and requires a great deal of work on the part of a computer. While it can be done by hand, it would take hours to get to the final number.

How the Bitcoin network works at a glance

Bitcoin operates on a proof-of-work model that requires computers to constantly calculate using trial and error to find the next viable block. Each block includes a hash of the previous one, as well as any transactional information that will be carried in the new block. Each block in a blockchain is a kind of ledger that contains a series of information, and each piece of information added changes the hash.

In order to be a viable hash that is accepted by the rules of the Bitcoin network, computers must constantly process different variations of numbers and letters to find the correct hash result. That’s why the system is called “proof of work,” because it has computers run thousands of hash possibilities per second as they race to find the “correct” one that creates a new block. Miners who earn the new block (calculate it faster) receive bitcoin as payment, as well as any transaction fees.

As soon as a new block is discovered, the job immediately stops to find the hash of that block and starts looking for the new one. The Bitcoin network was created in such a way that it can speed up the creation of new blocks and bitcoins as more miners compete for new blocks. This is essentially done by adding a 0 to the beginning of each hash code result. Requiring a 0 changes the entire input, which means that computers must work through all the calculations to arrive at a result of 0.

The more zeros, so to speak, the greater the number of calculations; when the hash rate is high and the network has strong mining activity, this difficulty setting is increased to account for all competition. Bitcoin aims to produce a new block every 10 minutes, and this is its way of speeding up mining traffic. A recent Bitcoin block had 19 leading zeros, meaning there is a 16 to the 19 chance of calculating a new block on each try. Hash rate is how many attempts are made per second to create a new block, and the current global hash rate is around 200 million terahashes per second. (A trillion hashes make a terahash.)
