How do miners solve a block?

Mining involves Blockchain miners who add bitcoin transaction data to Bitcoin’s global public ledger of past transactions . In the ledgers, blocks are secured by Blockchain miners and are connected to each other forming a chain.

You may want to look into local regulations where you live, but for now, bitcoin mining is legal in the U.S. and most other countries .

To solve a block, miners modify non-transaction data in the current block such that their hash result begins with a certain number (according to the current Difficulty, covered below) of zeroes . If you manually modify the string until you get a 0… result, you’ll soon see why this is considered “Proof of Work!”
