MerkleTree-Implementation

This is a merkle tree implementation using the merkletreejs library with support for root generation and leaf verification. It can be applied for checking eligible participants in an airdrop.

Dependencies

• merkletreejs library
• keccak256 Hash function

Example output

How it works

• Leaves (names of eligible users) are stored in the array => "eligibleAirdropParticipants".
• Leaves are hashed using keccak256 hash function and each hash is mapped to its corresponding leaf.
• The tree and its root are generated with the MerkleTree() class constructor and the getHexRoot() function.
• The checkIfNameIsValid() function verifies if a name is a valid leaf and part of the tree through steps and returns an output for true and false scenario.
