#AppleCryptoUpdate PoW requires network participants to perform complex computational tasks to prove that they have expended a certain amount of computational resources (time, energy). In cryptocurrency, for example, this means that whoever solves the problem first gets the right to add a new block to the blockchain and is rewarded with a certain amount of cryptocurrency.

At the core of PoW is the mining process. Miners compete to solve mathematical problems, and the first one to find a solution can add a block to the chain and receive a reward in the form of cryptocurrency. Technically, this process involves finding a value that, when passed through a hash function along with the data of the previous block and the transaction network, will yield a hash that meets certain difficulty criteria. Thus, creating a new block requires significant computational effort, making an attack on the network economically impractical.
