Block builder must include all storage slots individual txs will access This is consensus critical, so mismatching BAL lists will fail block validation ExecutionPayloadV4 adds a blockAccessList field thats a RLP encoded BAL (So engine API gets a bump) The builder has 2 phases: Collection phase and Build phase. Collection just records all touched state accesses. Build phase is encoding this info in RLP for consumption. BALs should include the following:Address wtih any state changes (storage, balance, nonce or code) Addresses accessed without state changes:targets of balance/extcodesize/extcodecopy/extcodehash opcode targets of call, callcode, delegatecall, staticcall target of create/create2 tx sender and recipient (even for 0 value) coinbase addy when receiving tx fees
