Tracking: Execution/Validation of blocks

[rakita]

Cover all needed validation and building for Ethereum block/header inside one library so it can be reused if needed. It will contain the main execution with EVM and all checks required for validating and creating blocks.

Some checks can differ depending on the consensus in place.

Common tasks:

• [x] Implement rlp for all primitive types.

Validator

Have utilities for stages to check parts of header/block/transactions fields. Those functions need to be aligned with the need (performance) of every stage. Some of those checks can be placed inside reth-primitives.

• [x] https://github.com/foundry-rs/reth/pull/152
• [x] Transaction signature recovery: https://github.com/foundry-rs/reth/pull/179
• [ ] Transaction verification

Builder

Have the ability with a list of transactions to create state change and all needed fields for the header. TODO tasks

Transaction execution

• [x] Storage provider: https://github.com/foundry-rs/reth/pull/172
• [x] Transaction execution with storage provider. https://github.com/foundry-rs/reth/pull/238

Have the ability to execute:

• Past transaction's
• given transaction on:
  • Latest state
  • State from past.
