An Archive Node is a type of full node in a blockchain network that maintains a complete historical record of all transactions and state changes. Unlike standard full nodes that only keep the current state of the blockchain, Archive Nodes store every block and transaction that ever occurred.This extensive storage allows Archive Nodes to provide any historical state of the blockchain at any point in time. They are essential for developers and researchers who need access to detailed data for analytics, auditing, or building applications that require historical insights.Running an Archive Node requires a significant amount of storage space and computing power due to the vast amount of data involved. While they play a crucial role in data accessibility, most users do not need to operate an Archive Node, as standard full nodes suffice for regular transaction processing and network participation.
