Introduction:
When you think of a Bitcoin hash, you may think of a very complex code that is absolutely impossible to solve. But it’s not that complex to get your head around. In this post, we will talk about what a hash is and what its purpose is in the blockchain.
What is a “Hash”? A hash is a simple algorithm that corresponds to your block to try to get a certain number that starts with a random amount of zeros. Millions of solo miners try to guess this number by randomly inputting numbers that make the result start with the right number of Zeros. A hash layout always starts the same: SHA-256, the number is 256 because that’s the number of bits in the hash value.
What happens when a hash is found?
A hash is found every 10 minutes on average, but what actually happens when somebody mines a bitcoin? Most bitcoin miners are attached to a personal bitcoin wallet where all percentages or full bitcoins are stored. Every 4 years, the bitcoin prize is halved so nowadays if you win you get about 3,1 bitcoins (plus fees).
Secure Your Winnings
Finding a solo block means receiving 3.125 BTC directly to your wallet — currently worth over $250,000. That amount should never sit on an exchange.
Two hardware wallets we recommend for solo miners:
Ledger Nano X (~$149) — Industry standard, supports BTC natively
Buy Ledger Nano X
Trezor Model T (~$179) — Open-source firmware, strong community trust
Buy Trezor Model T
Why does the hash stand for the proof of work?
The PoW also known as proof of work didn’t get the name from nowhere so, let’s take it apart and find out what it means.You might ask why proof? Well, it was named proof because of miners having to find the hash which needs specific requirements like a correct amount of zeros and because of the 256-bit encrypting system it requires to go through billions and trillions of different inputs and that basically means the “proof” of work and you have done to find the hash. Now let’s take apart “work”, as you know the hash is easy to verify but hard to create which creates the work part, and you might ask “why is it hard?” Creating a hash is hard because you have to start with adding block data and a random number and run it through the hash function which creates the large amount computational work and after all of that you still have to check if the hash has enough zeros for example, and that’s why it’s called the work.
