State expiry has been one of Ethereum's most discussed, least implemented scaling ideas. The core promise: stop nodes from having to hold 1.3 billion dormant storage slots that haven't been touched in over a year. Just expire them. Make clients store a proof if they ever need to resurrect one.

The problem is nobody had measured how often "dead" state actually comes back to life.

I tracked every storage slot reactivation on mainnet — slots that had been dormant for at least 12 months before being accessed again — across a 55-day window from December 18, 2025 to February 11, 2026. The results are stranger than expected.

Every full Ethereum node is currently lugging around 296 GB of state. Every account, every contract, every storage slot. Sync a fresh node and you're downloading all of it. Run a node continuously and you're holding all of it in your database, forever.

The uncomfortable truth: the vast majority of that state is dead. It hasn't moved in over a year. The addresses are abandoned, the contracts are deprecated, the protocols are gone. The data just... sits there. In every node on the network.
