Chain pruning is a method where older, unspendable transaction data is removed from a blockchain node’s local storage. This process allows nodes to discard historical information that is no longer essential for validating new transactions. It significantly reduces the disk space required to run a full node. The objective is to make running a node more accessible and less resource-intensive.
Context
Chain pruning is a vital strategy for managing the expanding data footprint of public blockchains, directly impacting network decentralization and accessibility. While full nodes retain complete history, pruned nodes still verify new transactions efficiently. Discussions often center on balancing data retention with the practical storage needs of network participants.
A novel sidechain architecture introduces mutual-dependence with the mainchain to offload resource market operations, fundamentally enhancing throughput and data efficiency.
