Blockchain technology often mentions 'consensus.' Can someone explain what consensus means in this context?

In blockchain technology, consensus refers to the agreement among the network participants (nodes) on the validity of transactions. This agreement is crucial for maintaining the integrity and security of the blockchain, ensuring that each transaction is accurately recorded and that the ledger is identical across all nodes. Consensus mechanisms prevent fraud and ensure that no single node can alter past transactions. There are several types of consensus algorithms, including Proof of Work (PoW), Proof of Stake (PoS), and others, each with its own method of achieving consensus and ensuring network reliability and security.
