62 - Storage
Storage is a 256-bit to 256-bit key-value store.
Unlike memory, which is volatile, storage is non-volatile and is maintained as part of the system state.
All locations are well-defined initially as zero.
This is accessed with SLOAD/SSTORE instructions.
- Non-Volatile (Persistent)
- Key-Value Store
- 256-bit <-> 256 bits
- Zero initialized
- storageRoot -> stateRoot
- SLOAD/SSTORE
