+Get an overview of the capabilities associated with an OP Stack chain.
+
+While the OP Stack allows for full customization, chains in the Superchain adhere to a [standard set of technical and governance parameters](/superchain/blockspace-charter), facilitating Superchain interoperability, network security, and ease of upgrading your chain.

+
+<sup>2</sup>The standard blockspace charter has a max gas limit of [200m](https://specs.optimism.io/protocol/configurability.html#gas-limit). Both gas limit and gas target can be configured through the system config.
+
+<sup>3</sup>While protocol blocktimes can be lowered to 1 second, subsecond blocktimes can be achieved using [Rollup Boost and Flashblocks](https://writings.flashbots.net/introducing-rollup-boost).
+
+<sup>4</sup>Although ETH is the gas token, chain operators can achieve the same UX of a custom gas token by using an ERC-20 paymaster.

+OP-Supervisor is a service that verifies cross-chain messages and manages interoperability between chains in the OP Stack.
 The main information it contains about other blockchains is:
-- Log entries, which could be [initiating messages](./explainer#how-messages-get-from-one-chain-to-the-other) for cross-domain messages.
-- Blockchain heads, which are the latest blocks at various levels of confidence and safety:
-  - Unsafe (the latest block available through the gossip protocol)
-  - Local-safe (the latest block written to L1)
-  - Cross-safe (the latest block written to L1, and for which all the dependencies are written to L1)
-  - Finalized (the latest block written to L1, and that L1 block is safe from reorgs)

 Note that bridging assets through the Superchain using `SuperchainERC20` never affects the total supply of your asset. The supply remains fixed, and bridging only changes the chain on which your asset is located. This keeps the token's total amount the same across all networks, ensuring its value stays stable during the move and that the `SuperchainERC20` retains a unified, global supply count.
