Once a transaction is added to the blockchain, it cannot be altered or deleted, ensuring the immutability of the network.
Blocks are groups of individual transactions that are validated and signed by miners to add to the blockchain. Each block contains a unique code called a hash, which links it to the previous block, creating a chain of blocks. This chain of blocks forms the blockchain, which is a distributed ledger that records all transactions made on the network.
Smart contracts are self-executing computer programs that automate tasks between different parties in a blockchain network. They’re programmed to execute automatically when specific conditions are met, eliminating the need for intermediaries. Smart contracts are a critical component of a blockchain architecture, as they enable secure and efficient transactions without the need for third-party intermediaries.
Consensus protocols are mechanisms that reconcile transactions across all nodes in the network by validating the information in a block. They ensure that all nodes in the network agree on the state of the blockchain, preventing any fraudulent activities. Consensus protocols are a critical component of a blockchain architecture, as they ensure the security and integrity of the network.
In conclusion, a blockchain architecture comprises several critical components that work together to ensure the security and integrity of the network. These components include nodes, miners, transactions, blocks, smart contracts, and consensus protocols. Blockchain technology has the potential to revolutionize various industries by providing secure, efficient, and transparent transactions.
