Functions

`constructor`

Disables initializers on the implementation, following best practices.

  function constructor(
  ) public

`initialize`

  function initialize(
  ) external

`setupCommittee`

Allows the admin to setup the members of the committee.

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

Parameters

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

`verifyMessage`

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

  function verifyMessage(
    bytes32 signedHash,
    bytes signaturesAndAddrs
  ) external

Parameters

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.

`getAmountOfMembers`

Returns the number of committee members.

  function getAmountOfMembers(
  ) public returns (uint256)

`getProcotolName`

Returns the protocol name.

  function getProcotolName(
  ) external returns (string)

Events

`CommitteeUpdated`

Emitted when the committee is updated.

  event CommitteeUpdated(
    bytes32 committeeHash
  )

Parameters

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