"Proof-of-Stake and Proof-of-Work or two consensus algorithms used within a blockchain to reach a consensus on the ledger's current state. Proof-of-Work was the original consensus algorithm developed for blockchains. It is used for confirming transactions and producing new blocks within that chain.
