How are crypto transactions validated?

For a public blockchain, the decision to add a transaction to the chain is made by consensus.

The people who own the computers in the network are incentivised to verify transactions through rewards.

A transaction is considered verified once the miner solves a cryptographic (mathematical) puzzle. Bitcoin uses a protocol called proof of work, which has a broad goal to prevent cyber attacks from any single entity or group. More specifically, Bitcoin uses the Secure Hash Algorithm 256 bit (SHA-256).

Do all miners mine the same transactions?
