Node connection refers to the way individual nodes, or computers, in a blockchain network communicate with each other. In these networks, each node stores a copy of the entire blockchain and participates in validating transactions.When nodes connect, they share information, such as new transactions and updates to the blockchain. This communication ensures that all nodes maintain a consistent and synchronized ledger. A strong connection among nodes enhances the network’s reliability, speed, and resistance to attacks.Nodes can connect in various ways, including direct connections or through intermediaries. The layout of these connections can affect the overall efficiency of the network. For example, a well-connected network can process transactions quicker and recover from failures more easily.The peer-to-peer structure of these networks allows for decentralization, meaning no single entity controls the entire system. This is key to achieving trust and transparency, as every participant can verify the integrity of transactions independently.
