What is BOScoin?

BOScoin is a Self-Evolving Cryptocurrency Platform for Trust Contracts.
“Trust Contracts” will provide a decidable and approachable framework for
creating and executing contracts on the blockchain.
The “Congress Network” is aimed towards creating a more democratic and productive decision making process.
And the incentive scheme and issuance plan is aimed towards creating value for the coin while deterring the centralization of power.
The Modified Federated Byzantine Agreement algorithm will allow for low latency transactions while being more energy efficient.
BOScoin aims to overcome the technical and operational issues inherent in many cryptocurrencies.

Trust Contracts

Trust Contracts are securely executable contracts based
on a decidable programming framework called Owlchain,
which consists of the Web Ontology Language and the
Timed Automata Language.

Congress Network

The Congress Network is the decision making body in
the BOScoin network which improves governance issues
arising in decentralized organizations and helps the system
continuously evolve into a more robust ecosystem.

BOScoin Ecosystem

Self-governing ecosystem for growth and evolution.
Offers a democratic & decentralized governance system and Trust Contracts through OWL and TAL.
