EcdsaDkgValidator
EcdsaDkgValidator
EcdsaDkgValidator allows performing a full validation of DKG result, including checking the format of fields in the result, declared selected group members, and signatures of operators supporting the result. The operator submitting the result should perform the validation using a free contract call before submitting the result to ensure their result is valid and can not be challenged. All other network operators should perform validation of the submitted result using a free contract call and challenge the result if the validation fails.
groupSize
Size of a group in DKG.
groupThreshold
The minimum number of group members needed to interact according to the protocol to produce a signature. The adversary can not learn anything about the key as long as it does not break into groupThreshold+1 of members.
activeThreshold
The minimum number of active and properly behaving group members during the DKG needed to accept the result. This number is higher than groupThreshold
to keep a safety margin for members becoming inactive after DKG so that the group can still produce signature.
publicKeyByteSize
Size in bytes of a public key produced by group members during the the DKG. The length assumes uncompressed ECDSA public key.
signatureByteSize
Size in bytes of a single signature produced by operator supporting DKG result.
sortitionPool
constructor
validate
Performs a full validation of DKG result, including checking the format of fields in the result, declared selected group members, and signatures of operators supporting the result.
Parameters
Return Values
validateFields
Performs a static validation of DKG result fields: lengths, ranges, and order of arrays.
Return Values
validateGroupMembers
Performs validation of group members as declared in DKG result against group members selected by the sortition pool.
Parameters
Return Values
validateSignatures
Performs validation of signatures supplied in DKG result. Note that this function does not check if addresses which supplied signatures supporting the result are the ones selected to the group by sortition pool. This function should be used together with validateGroupMembers
.
Parameters
Return Values
validateMembersHash
Performs validation of hashed group members that actively took part in DKG.
