Bitcoin blockchain proof of work

Cryptocurrency Mining and Proof of Work Algorithms - dummies A Proof of Work algorithm forces the miner to do some work — to use computational power — before submitting a block to the blockchain. The algorithm acts as security for a cryptocurrency by making unwanted actions costly and ensuring the intended outcome (the addition of only genuine, valid transactions to the blockchain) always occurs.
