What is proof of work in Blockchain?
Proof of Work(PoW) is the original consensus algorithm in a blockchain network. The algorithm is used to confirm the transaction and creates a new block to the chain. In this algorithm, minors (a group of people) compete against each other to complete the transaction on the network.
Does Blockchain eliminate duplication?
