Redis storage

TODO: Detail how current Redis storage is done

FMDB storage

TODO: Try using FMDB as storage backend

https://github.com/kriszyp/lmdb-js looks promising.

Native storage

TODO: Design native append-only storage for NEAR use case.

Main ideas:

  • Can store full block content similar to NEAR Lake
  • Append only index of block hashes by block index. Just store raw 32 byte hashes of blocks at location in file corresponding to block index
  • Append only index of update block indices by account ID and data key. Just 4 bytes per block index per updated key for observable future (enough for about 4 billion blocks).
  • Index of contract code and NEARFS (fs_store) blobs by SHA256 hash. Just 32 bytes per hash -> block index. Maybe remove blobs from normal block content and store them separately?
