-## Description
-
-The Challenger is an off-chain agent that listens for faulty claims made about the state of
-the L2 on the data availability layer. It is responsible for challenging these incorrect claims
-and ensuring the correctness of all finalized claims on the settlement layer.
-
-The Challenger agent is intended to be ran as a permissionless service by participants of the network
-alongside a [rollup-node](./rollup-node.md). Challenger agents will be rewarded in the form of the
-bond attached to the claims they disprove.
-
-## Terminology
-
- **data availability layer** - In the context of this document, the data availability layer is the
-  generic term for the location where claims about the state of the layer two are made. In the context
-  of Optimism, this is Ethereum Mainnet.
- **settlement layer** - In the context of this document, the settlement layer is the location of the
-  bridge as well as where funds deposited to the rollup reside. In the context of Optimism, this is
-  Ethereum Mainnet.
- **L2** - In the context of this document, the layer two of the Optimistic Rollup. In the context
-  of Optimism, this is the Optimism Mainnet.
- **rollup-node** - In the context of this document, the rollup node describes the
-  [rollup-node specification](./rollup-node.md). In the context of Optimism, this is the implementation
-  of the [rollup-node specification](./rollup-node.md), the `op-node`.
-
-## Event and Response Lifecycle
-
-The Challenger agent is expected to be able to listen for and respond to several different events
-on the data availability layer. These events and responses are parameterized depending on the type
-of dispute game being played, and the Challenger listens to different events and responds uniquely
-to each of the different game types. For specification of dispute game types, see the
-[Dispute Game Interfaces specification](./dispute-game-interface.md) and
-[Dispute Game specification](./dispute-game.md).

-
- [`L2OutputOracle.OutputProposed`](../packages/contracts-bedrock/src/L1/L2OutputOracle.sol#L57-70)
-  The `L2OutputOracle` contract emits this event when a new output is proposed on the data availability
-  layer. Each time an output is proposed, the Challenger should check to see if the output is equal
-  the output given by the `optimism_outputAtBlock` endpoint of their `rollup-node`.
-  - If it is, the Challenger should do nothing to challenge this output proposal.
-  - If it is not, the Challenger should respond by creating a new `DisputeGame` with the
-    `DisputeGameType.ATTESTATION` `gameType`, the correct output root as the `rootClaim`, and the abi-encoded
-    `l2BlockNumber` of the correct output root as the `extraData`.

-  Challenger agent should listen for this event and check if the `rootClaim` of the `AttestationDisputeGame`
-  created by the `DisputeGameFactory` is equal to the output root of their `rollup-node` at the game's `l2BlockNumber`.
-  - If it is, the Challenger should sign the [EIP-712 typeHash](./dispute-game.md) of the struct containing the
-    `AttestationDisputeGame`'s `rootClaim` and `l2BlockNumber`. The Challenger should then submit the abi-encoded
-    signature to the `AttestationDisputeGame`'s `challenge` function.
-  - If it is not, the Challenger should do nothing in support of this dispute game.

-## Attestation Dispute Game
-
-The output attestation based dispute game shifts the current permissioned output proposal process
-to a permissionless, social-consensus based architecture that can progressively decentralize over
-time by increasing the size of the signer set. In this "game," output proposals can be submitted
-permissionlessly. To prevent "invalid output proposals," a social quorum can revert an output proposal
-when an invalid one is discovered. The set of signers is maintained in the `SystemConfig` contract,
-and these signers will issue [EIP-712](https://eips.ethereum.org/EIPS/eip-712) signatures
-over canonical output roots and the `l2BlockNumber`s they commit to as attestations. To learn more,
-see the [DisputeGame Interface Spec](./dispute-game-interface.md).
-
-In the above language, an "invalid output proposal" is defined as an output proposal that represents
-a non-canonical state of the L2 chain.
-
-### Smart Contract Implementation
-
-The `AttestationDisputeGame` should implement the `IDisputeGame` interface and also be able to call
-out to the `L2OutputOracle`. It is expected that the `L2OutputOracle` will grant permissions to
-`AttestationDisputeGame` contracts to call its `deleteL2Outputs` function at the *specific* `l2BlockNumber`
-that is embedded in the `AttestationDisputeGame`'s `extraData`.
-
-The `AttestationDisputeGame` should be configured with a quorum ratio at deploy time. It should also
-maintain a set of attestor accounts, which is fetched by the `SystemConfig` contract and snapshotted
-at deploy time. This snapshot is necessary to have a fixed upper bound on resolution cost, which in
-turn gives a fix cost for the necessary bond attached to output proposals.
-
-The ability to add and remove attestor accounts should be enabled by a single immutable
-account that controls the `SystemConfig`. It should be impossible to remove accounts such that quorum
-is not able to be reached. It is ok to allow accounts to be added or removed in the middle of an
-open challenge, as it will not affect the `signerSet` that exists within open challenges.
-
-A challenge is created when an alternative output root for a given `l2BlockNumber` is presented to the
-`DisputeGameFactory` contract. Multiple challenges should be able to run in parallel.
-
-For simplicity, the `AttestationDisputeGame` does not need to track what output proposals are
-committed to as part of the attestations. It only needs to check that the attested output root
-is different than the proposed output root. If this is not checked, then it will be possible
-to remove output proposals that are in agreement with the attestations and create a griefing vector.
-
-#### Attestation Structure
-
-The EIP-712 [typeHash](https://eips.ethereum.org/EIPS/eip-712#rationale-for-typehash) should be
-defined as the following:
-
-```solidity
-TYPE_HASH = keccak256("Dispute(bytes32 outputRoot,uint256 l2BlockNumber)");
-```
-
-The components for the `typeHash` are as follows:
-
- `outputRoot` - The **correct** output root that commits to the given `l2BlockNumber`. This should be a
-  positive attestation where the `rootClaim` of the `AttestationDisputeGame` is the **correct** output root
-  for the given `l2BlockNumber`.
- `l2BlockNumber` - The L2 block number that the `outputRoot` commits to. The `outputRoot` should commit
-  to the entirety of the L2 state from genesis up to and including this `l2BlockNumber`.
-
-### Why EIP-712
-
-It is important to use EIP-712 to decouple the originator of the transaction and the attestor. This
-will allow a decentralized network of attestors that serve attestations to bots that are responsible
-for ensuring that all output proposals submitted to the network will not allow for malicious withdrawals
-from the bridge.
-
-It is important to have replay protection to ensure that attestations cannot be used more than once.
