blockchain-api

Blockchain API based on BasicBlockChain using node-addon-api to run multithreaded native code for faster hash computation and execution

Installation

git clone https://github.com/t348575/blockchain-api.git
cd blockchain-api
npm install

Testing

npm run test

Todo:

• Add functions for verification of chain and block
• Use web worker threads were possible
• Add support for other hash functions
