Tyche_Blockchain

This project is called Tyche Blockchain. It is created as the result of software engineering project course for final bachelor project in university of Zanjan.

About Tyche Blockchain:

Tyche Blockchain is focus on creating a blockchain based on proof-of-work and deploy Tyche Coin as the cryptocurrency.

It is based on JavaScript as the blockchain core and for blockchain backend. The frontend will be based on React but it is not deployed and created yet. The new ideas of Tyche Blockchain and Tyche Coin will be documented as fast as they deploy in the project.
