The consensus algorithm is a set of protocols used to ensure that all nodes in a blockchain network reach a consensus on the consistency and correctness of the data. Common consensus algorithms include Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerance (BFT) etc.↵↵Take Proof of Work (PoW) as an example, miners need to compete to generate new blocks by solving complex  mathematical problems. When a miner successfully solves the problem, they will"}]}],"pr":"9ae24a48bf1ce25f0575ca87c2e7117b42658e98692dd4df6c85d9aea799da5a"}
