Validator Nodes on the other hand, do everything that Witness Nodes do, but they also are responsible for validating the transactions. In addition to the transaction validation, they also work to produce options on btc new blocks. You can imagine Validator Nodes as the counterpart to an Ethereum/Bitcoin "miner." In the next section, I will walk you through how to setup and run a Witness Node. Legacy Addresses The Bitcoin consensus algorithm is called Proof of Work (PoW). This is the way for Bitcoin to solve the Byzantine General’s problem. PoW is, like the name suggests, a proof of performing the work, which is a mathematical challenge to validate the block. After solving the challenge, the block is added to the network and there is a reward for the node which solves it. This challenge requires a lot of computer power.
