My experimental take on a decentralized ledger

In plain words

This is an experimental decentralized ledger project launched in 2015. It's designed for developers and cryptocurrency enthusiasts interested in exploring blockchain technology concepts. The project is available on GitHub for those who want to examine the code or contribute to its development. As an experimental implementation, it serves as a technical exploration rather than a production-ready system.
