The dispute game factory allows the creation of dispute games, used to propose state rootsA cryptographic hash succinctly representing a state using a Merkle tree. and eventually challenge them. This variant exposes per-type reads only; the legacy array views (gameImpls[], initBonds[]) were removed in the new implementation.

Contains configuration parameters such as the SequencerA party responsible for ordering and executing transactions on the rollup. The sequencer verifies transactions, compresses the data into a block, and submits the data related to it to enable state reconstruction to Ethereum L1 as a single transaction. The data can be either transaction data or state diffs. address, gas limitThe maximum amount of gas a transaction or block may consume. on this chain and the unsafe blockAn ordered list of transactions and chain-related metadata that gets bundled together and published to the L1/DA layer. Nodes execute the transactions contained within blocks to change the rollup chain’s state. Protocol rules dictate what constitutes a valid block, and invalid blocks are skipped over. signer address.

The OptimismPortal contract is the main entry point to deposit funds from L1Layer 1 (L1) is a blockchain that is self-reliant on its validator set for its security and consensus properties. Ethereum is an example of a layer 1. Blockchains started receiving the moniker of layer 1 once layer 2 became a meaningful area of development. to L2Layer 2 (L2) is a category of technical solutions aimed to scale the base layer in a trust minimized way. This category includes solutions like rollups as well as state channels and plasma. Other solutions are able to scale further, but with the introduction of additional trust assumptions, which are therefore not trust minimized. Sometimes the term Layer 2 is used to refer to include these solutions too, like validiums and optimiums, but to distinguish between trust minimized and non trust minimized solutions they are often referred to as "light" L2s, opposed to "strong" L2s like rollups.. It also allows to prove and finalize withdrawals. It specifies which game type can be used for withdrawals, which currently is the SuperPermissionedDisputeGame.

Used to manage global configuration values for multiple OP Chains within a single Superchain networkA constellation of nodes (peers) that communicate via a peer-to-peer protocol, for example, in propagating transactions and blocks to other nodes.. The SuperchainConfig contract manages individual pause states for each chain connected to it, as well as a global pause state for all chains. The guardian role can pause either separately, but each pause expires after 3 months if left untouched.

A properly set up Security Council consists of at least 8 members with a threshold greater than 75%. What 'sufficiently decentralized' means is fundamentally subjective and L2BEAT evaluates each case individually. A Security Council is allowed to instantly upgrade Stage 1 rollups., SaferSafes

Used to bridgeA message-passing protocol between two blockchains. At its most basic, a token bridge consists of a smart contract which can escrow funds on one side of the bridge, and instruct the release or minting of corresponding assets on the other side, but bridges could also support arbitrary messages. How these instructions are validated is a critical factor in assessing the trust assumptions of a bridge. ERC-721 tokens from host chain to this chain.

Sends messages from host chain to this chain, and relays messages back onto host chain. In the event that a message sent from host chain to this chain is rejected for exceeding this chain’s epoch gas limitThe maximum amount of gas a transaction or block may consume., it can be resubmitted via this contract’s replay function.

Contains the latest confirmed state rootA cryptographic hash succinctly representing a state using a Merkle tree. that can be used as a starting point in a dispute game. This variant stores respectedGameType, retirementTimestamp, and disputeGameFinalityDelaySeconds locally and drops the legacy *FromGame fields, since the AggregateVerifier model does not expose vm()/weth()/absolutePrestate() on its game implementation.

Logic of the permissioned dispute game introduced in Upgrade 20. Only the proposerIn the context of L2s, the actor that proposes a claimed state root on L1. The term is also used in the context of Ethereum to refer to the actor that proposes a new block. configured in the DisputeGameFactory can create games of this type, and each one commits to a super root anchored to an L2Layer 2 (L2) is a category of technical solutions aimed to scale the base layer in a trust minimized way.

Unlike the permissioned game it replaces, it runs no VM and exposes no challenger, bond, clock or absolute prestate: validity is governed by the AnchorStateRegistry and the Guardian.

A helper contract that generates OptimismMintableERC20 contracts on the networkA constellation of nodes (peers) that communicate via a peer-to-peer protocol, for example, in propagating transactions and blocks to other nodes. it’s deployed to. OptimismMintableERC20 is a standard extension of the base ERC20 token contract designed to allow the L1StandardBridge contracts to mint and burn tokens. This makes it possible to use an OptimismMintableERC20 as this chain’s representation of a token on the host chain, or vice-versa.
