Three main components of Blockchain#Blocks - A block is a collection of data that contains transactional information. Each block is linked to the previous block through a cryptographic hash, forming a chain of blocks.
#Nodes - Nodes are individual computers or devices that participate in the blockchain network. They store a copy of the entire blockchain and validate transactions by reaching a consensus with other nodes.
#Consensus - Consensus mechanisms are the rules and algorithms that ensure agreement and validity of transactions within the blockchain network.
Popular consensus mechanisms
#PoW Proof of Work
#PoS Proof of Stake
#DPoS Delegated Proof of Stake.
Overall the blockchain involves interconnected blocks, a network of nodes, and consensus mechanisms to maintain the integrity and security of the system.
