Blockchain can be described as an open record of blocks partitioned into individual transactions. The consensus algorithm serves as the most crucial component of the blockchain, as it determines which transactions to include and exclude. Having a robust consensus algorithm is essential because any data recorded on the blockchain becomes unchangeable. Examples of consensus algorithms include Proof of Work, Proof of Stake, Proof of Authority, Proof of History, and more. Among these, Delegated Proof of Stake (DPoS) stands out as the most scalable and environmentally sustainable option. This is why Onschain employs DPoS as its consensus algorithm.
