About 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(OWL) and the Timed Automata Language(TAL). Trust Contracts aim to overcome the issues regarding non-decidable smart contracts by using a more contained and comprehensible programming framework which provides secure and decidable transactions of contracts.

The owlchain’s hierarchy was designed as a general blockchain model to accommodate multiple ontology models. The owlchain combines the feature of the reasoner and consensus protocol to handle the Trust Contract.


Democratic decision-making body for BOScoin
BOScoin constitutes a governance system whereby node operators referred to as the Congress Network can participate in creating and voting on proposals in order to continuously improve the software and ecosystem. The Congress Network interacts with non-congress users in three ways; transactions, proposals and coin freezing.

1. Transactions
When a transaction of digital assets is requested by a user, the request is sent to the Congress Network. For a simple transfer of BOScoin, when a node confirms the block –roughly every 5 seconds– the user’s transactions will be confirmed, and the BOScoin will be transferred to another wallet

2. Proposals
Proposals are Commons Budget spending plans that are submitted to the Congress Network. When a proposal is made, the ‘net percentage point difference’ between the positive and negative votes must exceed 10% for the proposal to be passed. When the proposal is passed, the requested coins will be sent to the proposer

3. Coin Freezing
Coin Freezing is a Proof of Stake concept where if a user locks-in their coins and in return they will receive interest based on the number of coins frozen and the length of time the coins are stored. Frozen coins are used as collateral in case of attempted forgery of the blockchain


New coins are issued in four ways; initial development budget (0.5bil, 10%), confirmation rewards(1.8bil, 36%), freezing rewards(0.9bil, 18%) and the Commons Budget(1.8bil, 36%). We aim to issue a total of 5.0 billion coins over the next 100 years. These values are subject to change.
