Visualize Bitcoin Hashing

Henry: 24 May 2022

According to,

BitCoin uses the SHA-256 hash algorithm to generate verifiably "random" numbers in a way that requires a predictable amount of CPU effort. Generating a SHA-256 hash with a value less than the current target solves a block and wins you some coins.

Here is an example for web logs;

Obviously solving the hash takes many iterations. I'm curious if there anything that currently lets you visualize a miner hashing?

I got linked this question.

I made a tool which includes a component that allows one to simulate mining:

It's not entirely accurate; it doesn't support BIP 34, so the block height is not reflected in the coinbase tx, and it's still got some bugs. Currently in alpha. But it can give you some pointers.

It'll construct a block on top of the tip of the current best chain, with a coinbase transaction and nothing else, then start hashing at 4 hashes/sec, showing every failed attempt (which at this hashrate, is likely to be all of them).
