Simple reference implementation of Merkle trees for general use.

Sample blockchain concept implementation from scratch.

In cryptography and computer science, a hash tree or Merkle Hash Tree is a tree in which every "leaf" (node) is labelled with the cryptographic hash of a data block, and every node that is not a leaf (called a branch, inner node, or inode) is labelled with the cryptographic hash of the labels of its child nodes

A mixer that uses merkle trees and zero-knowledge proofs to provide shielded transfers of Ethereum

Implementing the use case of Merkel Tree in verifying if the name exists in the tree or not.

The Merkel Tree Gift List project manages gift assignments based on a Merkel tree structure. Users input person and gift data and hashed into the tree. Clients provide a name and proof to the server. If the hash matches the stored Merkel root, gifts are assigned. This ensures secure and accurate gift management.
