The Bitcoin mining algorithm, known as SHA-256 (Secure Hash Algorithm 256-bit), is the cryptographic foundation that secures the entire Bitcoin network and validates every transaction. It operates within a Proof-of-Work consensus framework: miners compete to find a hash below a dynamically adjusted target by incrementing a nonce in the block header. The first miner to produce a valid hash broadcasts the block and receives the block reward plus fees. This process ensures that altering historical blocks would require redoing the computational work, making the ledger immutable.
SHA-256 is a deterministic, one-way hash function that outputs a fixed 256-bit digest. Its design makes it computationally infeasible to reverse a hash or find two inputs that produce the same output. Bitcoin mining harnesses this property by requiring the block hash to start with a certain number of zero bits — the mining difficulty. Every 2,016 blocks (roughly two weeks) the network recalculates the difficulty to maintain an average block interval of ten minutes, keeping issuance predictable regardless of total hashing power.
