EcdsaInactivity

EcdsaInactivity

Claim

struct Claim {
  bytes32 walletID;
  uint256[] inactiveMembersIndices;
  bool heartbeatFailed;
  bytes signatures;
  uint256[] signingMembersIndices;
}

groupThreshold

uint256 groupThreshold

The minimum number of wallet signing group members needed to interact according to the protocol to produce a valid inactivity claim.

signatureByteSize

uint256 signatureByteSize

Size in bytes of a single signature produced by member supporting the inactivity claim.

verifyClaim

function verifyClaim(contract SortitionPool sortitionPool, struct EcdsaInactivity.Claim claim, bytes walletPubKey, uint256 nonce, uint32[] groupMembers) external view returns (uint32[] inactiveMembers)

Verifies the inactivity claim according to the rules defined in Claim struct documentation. Reverts if verification fails.

Wallet signing group members hash is validated upstream in WalletRegistry.notifyOperatorInactivity()

Parameters

Name	Type	Description
sortitionPool	contract SortitionPool	Sortition pool reference
claim	struct EcdsaInactivity.Claim	Inactivity claim
walletPubKey	bytes	Public key of the wallet
nonce	uint256	Current inactivity nonce for wallet used in the claim
groupMembers	uint32[]	Identifiers of group members

Return Values

Name	Type	Description
inactiveMembers	uint32[]	Identifiers of members who are inactive

validateMembersIndices

function validateMembersIndices(uint256[] indices, uint256 groupSize) internal pure

Validates members indices array. Array is considered valid if its size and each single index are in [1, groupSize] range, indexes are unique, and sorted in an ascending order. Reverts if validation fails.

Parameters

Name	Type	Description
indices	uint256[]	Array to validate.
groupSize	uint256	Group size used as reference.
