A blockchain network is a decentralized system that enables multiple participants to record and verify transactions securely. It consists of a chain of blocks, each containing a list of transactions. These blocks are linked together using cryptographic hashes, ensuring that any changes to a block affect all subsequent blocks.
Each participant, often referred to as a node, has access to a copy of the entire blockchain. This transparency helps maintain trust, as all transactions are visible and cannot be altered without consensus from the network. When a new transaction occurs, it is broadcast to all nodes.
They work together to validate and confirm the transaction through a process called consensus, which can involve various methods like proof of work or proof of stake. Once verified, the transaction is added to a new block and appended to the blockchain. This structure promotes security and resilience, making it difficult for malicious actors to alter past transactions. Overall, a blockchain network fosters trust among users while eliminating the need for intermediaries.
