Blockchain network layer refers to the foundational structure that facilitates the operation of a blockchain system. This layer serves as the communication framework between nodes, enabling them to share information and validate transactions.At its core, this layer is responsible for maintaining the integrity and security of the network. It uses protocols to ensure that data is transmitted accurately and securely, preventing unauthorized access and manipulation. Each node in the network keeps a copy of the blockchain, which helps in achieving consensus on the state of the ledger.The network layer also handles the process of mining or validating new transactions, leading to the generation of new blocks. As these new blocks are added to the chain, the network ensures that all participants have a synchronized and updated version of the ledger.Overall, the blockchain network layer plays a crucial role in ensuring that the decentralized system functions smoothly, promoting trust and transparency among users.
