FVM M2.1: Talc release (1)

[raulk]

Goal

To allow early experimenters to get an initial impression of running FEVM contracts on Filecoin. Only basic contracts will be supported at this stage, i.e. contracts that are self-contained, do not make calls to other contracts nor to precompiles. For example, ERC-20 contracts should be deployable at this stage. No Ethereum JSON-RPC API is supported at this stage, and contracts can only be deployed by Filecoin messages via Init actor deployment. No universal addressing scheme is supported yet.

On the specs track, we plan to complete the specs work for Universal Addressing (#690) and wrap up the full picture for Account Abstraction and native Ethereum transaction support (#721 and
filecoin-project/FIPs#388). (Moved to Selenium)

Implementation scope

• Getting fvm-evm into the built-in actors bundle.
• Drop/stash speculative and unused code in fvm-evm (e.g. bridge/registry?)
  • At this stage, EVM contract deployment is performed by instantiating the EVM runtime directly.
  • We are aiming to discard the bridge/registry as part of Universal addressing spec and foreign runtime support #690. If it ends up being necessary, we will reintroduce the components (potentially with different responsibilities/behaviour).
• Map some of the Filecoin context to EVM calls.
• Integration tests.

Work burndown

• Recover pubkey syscall #627 (to support ecrecover precompile)
• introduce a crypto::recover_secp_public_key syscall. #707
• fvm-evm: absorb into built-in actors #693
• EVM foreign runtime prototype on ref-fvm #735
• EVM runtime: Implement FVM storage mappings for EVM OPCODES  #683
