Blockchains are incredible at making a shared record nobody can quietly rewrite. They’re terrible at being a free, eternal database. That tension is finally catching up.
If every token, allowance, airdrop, NFT, and abandoned contract lives forever, state balloons. Nodes get heavier. Fewer people can run them. Fees reflect that pressure. And at some point, the network has to say no.
That’s where “state expiry” comes in. Not a silver bullet, not an overnight switch. Just a set of strategies that say: the chain keeps the most important stuff accessible, and the rest needs proofs, snapshots, or a fresh touch to stick around.

State growth is compounding
Measured weekly new Ethereum state rose from roughly 105 MiB to ~326 MiB after gas limit increases, or about 116 GiB per year of extra state pressure (HackMD — Week 2).
Expiry vs history pruning
History expiry drops old block bodies and receipts. State expiry targets long-lived account and storage entries
