| [Gas Limit](./system_config.md#gaslimit-uint64) | Gas limit of the L2 blocks is configured through the system config. | [System Config Owner](#admin-roles) | No higher than 200,000,000 gas | Chain operators are driven to maintain a stable and reliable chain. When considering to change this value, careful deliberation is necessary. |
| Genesis state | Initial state at chain genesis, including code and storage of predeploys (all L2 smart contracts). See [Predeploy](../glossary.md#l2-genesis-block). | Static | Only standard predeploys and preinstalls, no additional state. | Homogeneity & standardization, ensures initial state is secure. |
| [L2 block time](https://github.com/ethereum-optimism/optimism/blob/c927ed9e8af501fd330349607a2b09a876a9a1fb/packages/contracts-bedrock/src/L1/L2OutputOracle.sol#L105) | Frequency with which blocks are produced as a result of derivation. | [L1 Proxy Admin](#admin-roles) | 2 seconds | High security & [interoperability](../interop/overview.md) compatibility requirement, until de-risked/solved at app layer. |
| [Resource config](https://github.com/ethereum-optimism/optimism/blob/c927ed9e8af501fd330349607a2b09a876a9a1fb/packages/contracts-bedrock/src/L1/SystemConfig.sol#L338-L340) | Config for the EIP-1559 based curve used for the deposit gas market. | [System Config Owner](#admin-roles) | See [resource config table](#resource-config). | Constraints are imposed in [code](https://github.com/ethereum-optimism/optimism/blob/c927ed9e8af501fd330349607a2b09a876a9a1fb/packages/contracts-bedrock/src/L1/SystemConfig.sol#L345-L365) when setting the resource config. |

| Sequencing window | Maximum allowed batch submission gap, after which L1 fallback is triggered in derivation. | Static | 12 hours | This is an important value for constraining the sequencer's ability to re-order transactions; higher values would pose a risk to User Protections. |
| [Start block](https://github.com/ethereum-optimism/optimism/blob/c927ed9e8af501fd330349607a2b09a876a9a1fb/packages/contracts-bedrock/src/L1/SystemConfig.sol#L184) | Block at which the system config was initialized the first time. | [L1 Proxy Admin](#admin-roles) | The block where the SystemConfig was initialized. | Simple clear restriction. |
| [Superchain target](../protocol/superchain-upgrades.md#superchain-target) | Choice of cross-L2 configuration. May be omitted in isolated OP Stack deployments. Includes SuperchainConfig and ProtocolVersions contract addresses. | Static | Mainnet or Sepolia | A superchain target defines a set of layer 2 chains which share `SuperchainConfig` and `ProtocolVersions` contracts deployed on layer 1. |
