Functions¶

Disables initializers on the implementation, following best practices.

  function constructor(
  ) public

  function initialize(
  ) external

Allows the admin to setup the members of the committee.

Note

The system requires N/M signatures where N => _requiredAmountOfSignatures and M => urls.length.
The number of urls must be the same as addresses encoded in the addrsBytes.
A member is represented by a url and the address contained in urls[i] and addrsBytes. [i*_ADDR_SIZE : i*_ADDR_SIZE + _ADDR_SIZE].

  function setupCommittee(
    uint256 _requiredAmountOfSignatures,
    string[] urls,
    bytes addrsBytes
  ) external

Name	Type	Description
`_requiredAmountOfSignatures`	uint256	Required amount of signatures
`urls`	string[]	List of urls of the members of the committee
`addrsBytes`	bytes	Byte array that contains the addressess of the members of the committee

Verifies that the given signedHash has been signed by the requiredAmountOfSignatures committee members.

  function verifyMessage(
    bytes32 signedHash,
    bytes signaturesAndAddrs
  ) external

Name	Type	Description
`signedHash`	bytes32	Hash that must have been signed by the requiredAmountOfSignatures of committee members.
`signaturesAndAddrs`	bytes	Byte array containing signatures and all addresses of the committee members in ascending order [signature 0, …, signature requiredAmountOfSignatures -1, address 0, … address N]. Note that all signatures are ECDSA, therefore each must be 65 bytes long.

Returns the number of committee members.

  function getAmountOfMembers(
  ) public returns (uint256)

Returns the protocol name.

  function getProcotolName(
  ) external returns (string)

Emitted when the committee is updated.

  event CommitteeUpdated(
    bytes32 committeeHash
  )

Name	Type	Description
`committeeHash`	bytes32	hash of the addresses of the committee members
