Let's talk about hash functions:
Common Bitcoin P2PKH and P2WPKH addresses first apply SHA-256 to the public key, then RIPEMD-160, producing a 160-bit public key hash.
Proof of work is effective because hash results can't be predicted in advance; finding a hash that meets the difficulty target requires repeated attempts.
