| - | - Mitigates contract breakage risks introduced by EIP-2929, as transactions could pre-specify and pre-pay for the accounts and storage slots that the transaction plans to access; as a result, in the actual execution, the SLOAD and EXT* opcodes would only cost 100 gas: low enough that it would not only prevent breakage due to that EIP but also "unstuck" any contracts that became stuck due to EIP 1884. | + | - Mitigates contract breakage risks introduced by [[dido:public:ra:xapend:xapend.b_stds:defact:ethereum:eip:2929 | EIP-2929]], as transactions could pre-specify and pre-pay for the accounts and storage slots that the transaction plans to access; as a result, in the actual execution, the SLOAD and EXT* opcodes would only cost 100 gas: low enough that it would not only prevent breakage due to that EIP but also "unstuck" any contracts that became stuck due to [[ dido:public:ra:xapend:xapend.b_stds:defact:ethereum:eip:1884 | EIP 1884]]. |
| - Introduces the access list format and the logic for handling the format. This logic can later be repurposed for many other purposes, including block-wide witnesses, use in ReGenesis, moving toward static state access over time, and more. | - Introduces the access list format and the logic for handling the format.
