'How to Write Smart Contracts for Merkle Tree Using Solidity' blockchain smartcontracts
The verification is done by merging data layers to form a single Merkle Root. This Merkle root is then used to verify any or all data in the Merkle tree. The tree is also called a Binary Hash Tree because the hierarchical data structure is built from hashes of contrasting data blocks. The tree comprises the leaves or leaf nodes, branches, and the Merkle Root.The leaf nodes store the hash value of hashed data transactions in a block.
They are called non-leaf nodes because they have no direct connection with the transaction. However, the non-leaf nodes might be in layers, depending on the number of transactions in a block. Irrespective of the number of layers formed, all the layers are referred to as Branches or Intermediate nodes.The non-leaf nodes are also jointly hashed in pairs leading to a final layer of just two nodes.
