## State Expiry

State expiry is a mechanism where data that has not been accessed for a long period is moved out of the active state. This data is archived or moved to a slower, less expensive storage layer, effectively removing it from the immediate memory of network nodes.

If a user needs to access the data again, they must provide a proof that the data exists, which restores it to the active state. This prevents the active state from growing indefinitely, ensuring that nodes can operate with lower hardware requirements.

It is a key strategy for maintaining the long-term viability of decentralized networks. State expiry effectively creates a tiered storage system based on data usage frequency.
