Blockchain technology is revolutionizing the way we handle data and transactions. Understanding its architecture is crucial to grasp its full potential. Below, we delve into the key components of a blockchain architecture.
Key Components
- Nodes: These are the individual devices or computers that participate in the blockchain network. Each node holds a copy of the blockchain and helps maintain its integrity.
- Blocks: Blocks are the individual units of data that make up the blockchain. Each block contains a set of transactions, a unique identifier called a hash, and the hash of the previous block.
- Chain: The chain is the sequence of blocks that are linked together using their hashes. This structure ensures the immutability and security of the blockchain.
- Consensus Algorithm: This is the mechanism by which the network agrees on the validity of transactions. Common algorithms include Proof of Work (PoW) and Proof of Stake (PoS).
