Blockchain can be defined as an open ledger of blocks sub-divided into atomic transactions. The consensus algorithm is the most important module of the blockchain as it decides which transactions to be included and which not to be included. It is important to have a strong consensus algorithm because once anything is recorded on the blockchain then that is immutable. Proof of Work, Proof of Stake, Proof of Authority, Proof of History, etc are types of consensus algorithms. Out of them Delegated Proof of Stake (DPoS) is the most scalable and ecologically viable. That’s why DPoS is used as a consensus algorithm in Lycanchain.
