## Issue Addressed Closes #2286 Closes #2538 Closes #2342 ## Proposed Changes Part II of major slasher optimisations after #2767 These changes will be backwards-incompatible due to the move to MDBX (and the schema change) 😱 * [x] Shrink attester keys from 16 bytes to 7 bytes. * [x] Shrink attester records from 64 bytes to 6 bytes. * [x] Separate `DiskConfig` from regular `Config`. * [x] Add configuration for the LRU cache size. * [x] Add a "migration" that deletes any legacy LMDB database.
