Merge genesis tools

Some tooling to help create an Ethereum genesis state for post-merge testing. See Rayonism for early Merge testnet efforts.

Deposit contract

The deposit contract is embedded into genesis, in an empty form (testnet genesis-validators are pre-mined, no need for deposits).

To embed the contract, we need:

• To embed the run-time code of the contract, not the deployment code
  • Use: solc --bin-runtime
• Initialize the initial storage, normally initialized by the contract constructor
  • Reverse engineered from contract storage debugger (remix IDE)
  • Verified with compute_initial_storage
  • Matching the storage layout: solc --storage-layout
• We embed an empty deposit tree, there are no missing deposit events.

For every testnet, this part of the config will be the same. The 0x4242424242424242424242424242424242424242 part is the deposit contract address, and it can be set to anything (pick some nice vanity address if you like).

Solc 0.6.11 was used for the original deposit contract, and formally verified, so we stick with that here. See https://github.com/ethereum/solidity/releases/tag/v0.6.11

To generate the storage layout data:

solc --optimize --optimize-runs 5000000 --metadata-literal --bin-runtime --storage-layout deposit_contract.sol

To compute the storage key-value pairs:

(venv) python compute_initial_storage.py
