Yorke Rhodes	76f7ecafff	feat: attributable fraud for signers (#4284 ) ### Description Implements fraud proof attributions for checkpoint signers (validators). It is important to have a record of attribution in storage for slashing replay protection. We also maintain a [whitelist of merkle tree hooks](`b14f997810/solidity/contracts/libs/CheckpointLib.sol (L50-L54)`) such that validators cannot simply lie about this part of the checkpoint and circumvent fraud proofs. ### Backward compatibility Yes ### Testing Unit Tests	4 months ago
Yorke Rhodes	cb404cb85c	feat: implement checkpoint fraud proofs (#4277 ) ### Description Implements 4 categories of checkpoint fraud proofs for use in future validator slashing protocol: 1. premature: if a checkpoint index is greater than the corresponding mailbox count, it is fraudulent 2. non local: if a checkpoint origin does not match the checkpoint's mailbox domain, it is fraudulent 3. message id: if a checkpoint message ID differs from the actual message ID (verified by merkle proof) at the checkpoint index, it is fraudulent 4. root: if a checkpoint root differs from the actual root (verified by merkle proof + root reconstruction) at the checkpoint index, it is fraudulent Notably this is implemented independently from signature verification to allow for multiple checkpoint signing schemes to reuse the same checkpoint logic. ### Related issues - Touches https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/3799 - See https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/2431 for previous discussions ### Backward compatibility Yes ### Testing Unit testing with fixtures in `vectors/merkle.json` that are generated by the rust merkle tree and proof code	4 months ago

Yorke Rhodes	50f04db1fa	Make merkle proofs optional on multisig ISM (#2173 ) ### Description Validators currently sign `(root, index)` checkpoints and during verification, a `message` is passed as calldata, an `id()` is derived, and a `proof` of `id()` at `index` in `root` is verified This provides “all or nothing” censorship resistance guarantees because a validator can only sign roots to allow any contained messages to be processed. We have considered alternatives where validators sign `message` directly and we lose censorship resistance in exchange for eliminating merkle proof verification gas costs. However, if validators sign `(root, index, message)` tuples, we can skip merkle proof verification on the destination chain while still maintaining censorship resistance by providing two valid metadata formats: 1. existing validator signatures and merkle proof verification of inclusion 2. including merkle proof verification for pathway where validators are censoring `message` It’s worth noting the validator is required to index event data to produce this new signature format. However, this does not require historical indexing and new validators being spun up can simply begin indexing from tip.

Asa Oines	e8d90775f7	Add Aggregation ISM (#1737 ) ### Description This PR introduces the Aggregation ISM, which requires interchain messages to be verified by an m-of-n ISM set. This PR also introduces a new MultisigISM, which does not make use of the "commitment" optimization in its metadata. The previous MultisigISM has been moved to LegacyMultisigISM. Both AggregationISM and MultisigISM have abstract contracts that require `valuesAndThreshold` implementations. This PR implements versions with static m-of-n sets, using the EIP-3448 MetaProxy standard. These implementations are intended to be combined with a future RoutingISM implementation to replace LegacyMultisigISM. ### Drive-by changes - genhtml in solidity code coverage ### Related issues - Fixes #1522 ### Backward compatibility _Are these changes backward compatible?_ Yes ### Testing _What kind of testing have these changes undergone?
