v1.0.0

Breaking changes

1. Uses width instead of the total size of MMR for inclusion proof
2. Supports roll up function for optimistic roll up
3. Leaf hash method is changed

• before:

  function hashLeaf(uint256 index, bytes memory data) public pure returns (bytes32) {
      return keccak256(abi.encodePacked(index, data));
  }

• after:

  function hashLeaf(uint256 index, bytes32 memory hashedData) public pure returns (bytes32) {
      return keccak256(abi.encodePacked(index, hashedData));
  }

  Data will be hashed before getting hashed with the index

Interface changes

1. hashLeaf

   • before:

     function hashLeaf(uint256 index, bytes memory data) public pure returns (bytes32)

   • after:

     function hashLeaf(uint256 index, bytes32 hashedData) public pure returns (bytes32)

2. getMerlkeProof()

   • before:

     function getMerkleProof(uint256 index) public view returns (
         bytes32 root,
         uint256 size,
         bytes32[] memory peakBagging,
         bytes32[] memory siblings
     )

   • after:

     function getMerkleProof(uint256 index) public view returns (
         bytes32 root,
         uint256 width,
         bytes32[] memory peakBagging,
         bytes32[] memory siblings
     )

3. inclusionProof

   • before:

     function hashLeaf(uint256 index, bytes memory data) public pure returns (bytes32)

   • after:

     function hashLeaf(uint256 index, bytes32 hashedData) public pure returns (bytes32)

4. getPeaks -> getPeakIndexes

   • before:

     function getPeaks(uint256 size) public pure returns (uint256[] memory peaks)

   • after:

     function getPeakIndexes(uint256 width) public pure returns (uint256[] memory peakIndexes)
