# Scaling Upgrades Concentrate Who Holds Chain Data

Each round of node-scaling upgrades (statelessness, history expiry, data availability sampling) relieves storage cost by shifting dependence onto a small set of operators willing to serve state and history, so protocol scaling debates keep recurring as fights over data-serving centralization rather than throughput.

## Recent evidence

- [confirms] Ethereum Researchers Warn Planned Upgrades Could Concentrate Who Holds the Chain's State (2026-08-05): A new Ethereum research proposal argues that statelessness and history expiry solve node storage while creating dependence on a small set of operators willing to serve the data. The warning comes from researchers inside the roadmap process rather than outside critics, putting the centralization trade on the record before the upgrades ship.
