Archival Node Economics

Archival node economics concerns the financial incentives and operational costs of running a node that stores the entire history of a blockchain. Unlike standard nodes, archival nodes keep every state change ever recorded, which requires massive amounts of storage and bandwidth.

Because these nodes are essential for historical data analysis and some DeFi protocols, the cost of running them is significant. There is currently no direct protocol-level reward for running an archival node, leading to reliance on third-party infrastructure providers.

This creates a centralization risk as only well-funded entities can afford to maintain these nodes. The field studies how to incentivize decentralized access to historical data.
