Filecoin HAMTs need to have byte serializing keys to be compliant with the spec and the conforming implementation used by lotus. However the implementation as it stands accepts arbitrary cbor...

EVM Storage: No hashing in HAMT

1

Part of https://github.com/filecoin-project/ref-fvm/issues/859 Depends on https://github.com/filecoin-project/ref-fvm/issues/888 The HAMT hashes keys before accessing the data to keep the tree size predictable and independent of key-size. This, however, is not needed for...

Part of https://github.com/filecoin-project/ref-fvm/issues/859 Depends on https://github.com/filecoin-project/ref-fvm/issues/890 The HAMT has buckets of size 3 for KV pairs; once there are more items under the same key-prefix, it sinks them into sub-nodes....

Part of https://github.com/filecoin-project/ref-fvm/issues/859 Depends on https://github.com/filecoin-project/ref-fvm/issues/888 The HAMT consists of a root `Node`, which contains a sparse vector of `Pointer`s. Each `Pointer` can be a `Link` to another `Node` or...

EVM Storage: Hashing as syscall

2

Part of https://github.com/filecoin-project/ref-fvm/issues/859 Even though https://github.com/filecoin-project/ref-fvm/issues/890 disables key hashing in the HAMT, ~it will still calculate hashes for the CID of `Node`s.~ Normal HAMT usage will still do hashing of...

Part of https://github.com/filecoin-project/ref-fvm/issues/859 The [current implementation](https://github.com/filecoin-project/builtin-actors/blob/next/actors/evm/src/interpreter/system.rs#L68) of `set_storage` returns a `StorageStatus` which has an `Unchanged` value if the value being stored matches the existing entry, however it still stores the...

Part of https://github.com/filecoin-project/ref-fvm/issues/859 Depends on https://github.com/filecoin-project/ref-fvm/issues/887 Create a new module under `builtin-actors/actors/evm/tests` that runs a couple of scenarios with the test contract and captures the statistics about storage access. Ultimately...
