Persistence Implementation + +**Status**: Draft design +([Issue #522](https://github.com/o1-labs/mina-rust/issues/522), see +[persistence-design](persistence-design)) + +The ledger is currently kept entirely in memory, which is not sustainable for +mainnet's scale. Persistence is required for: + +- Reducing memory usage to handle mainnet-sized ledgers and amount of SNARKs +- Enabling fast node restarts without full resync +- Supporting webnodes with browser storage constraints +- Providing a clean foundation for implementing SNARK verification deduplication + +**Note**: There is a very old implementation for on-disk storage in +`ledger/src/ondisk` that was never used - a lightweight key-value store +implemented to avoid the RocksDB dependency. This is unrelated to the new +persistence design which intends to solve persistence for everything, not just +the ledger. But the old implementation may be worth revisiting anyway. + +**Performance Impact**: The importance of SNARK verification deduplication for +mainnet performance has been demonstrated in the OCaml node, where we achieved +dramatic improvements (8-14 seconds → 0.015 seconds for block application).

Automatic Hardfork Handling + +**Status**: Not implemented + +The Mina Rust node needs a mechanism to automatically handle protocol hardforks +to maintain compatibility with the network as it evolves. + +**Requirements**: + +- Detection of hardfork activation points +- Automatic protocol rule updates +- Backward compatibility during transition periods +- Clear migration paths for node operators + +### 5.
