JavaScript tools for creating Merkle trees, generating merkle proofs, and verification of merkle proofs.

JavaScript client for Exonum blockchain

BTCert authenticates academic certificates by means of a digital credential that allows immediate verification by third parties. BTCerts uses blockchain and cryptographic techniques to create a certification infrastructure based on the standard Blockcerts

JS - Solidity sha3 merkle tree bridge. Generate proofs in JS; verify in Solidity.

Construct merkle trees with MerkleTree.js and verify merkle proofs in Solidity.

A performance conscious library for merkle root and tree calculations.

Solidity NFT whitelist contract example using MerkleTree.js for constructing merkle root and merkle proofs.

MerkleMe allows you to create a whitelist without needing to understand or implement your own Merkle Tree. It allows you to generate proofs on the fly without running a node server. With MerkleMe, adding a whitelist to your project is as simple as copy + paste & integrating one simple post request into your frontend.

Multi-chain P2P Universal Asset Trading Protocol powered by Filecoin / IPFS networks

Trace back system base on BlockChain and MerkleTree; Ethereum +FLask + HTML5

Inheritable is a Web3 Will solution for secure, decentralized inheritance on Base. It adds claims to a Merkle Tree whose root is Anchored to Base with a Quantum-Resistant signature, and establishes a Decentralized Oracle of Death to unlock claims. | Built for EthDenver #BUIDLthon 2023 by Omar ElNaggar, Paul Loh, Intel Chen, and Zile Cao

Efficient token air drop using Merkle Tree and Solidity

Checkpoint git commits to an Ethereum smart contract and verify commits as Merkle tree

Print simple ascii binary trees in JavaScript

Lambda called on lambda finds/creates lambda, each with lazy-evaled 256 bit global DAG ids. Each lambda has 2 child lambdas. A kind of number that is a universal-pattern-calculus-combinator. Axgob.js (in dagball project, lib dir) is incomplete newer version of this. A fork-editable multiverse of all possible lambdas.
