Agoras is an application over Tau-Chain, being first and foremost a smart currency offering predictable and verifiable contracts. Tau is a decentralized blockchain network intended to solve the bottlenecks inherent in large-scale human communication and accelerate productivity in human collaboration using logic-based artificial intelligence.Agoras is a network with a cryptocurrency to be implemented over Tau allowing the following features: Self-Definition: Built over the Tau technology, Agoras is software effectively controlled by its many usersKnowledge-Economy: Leveraging Tau’s knowledge representation and collaborative formalization features in order to allow knowledge owners and creators to offer it for paid usage, as well as for knowledge seekers to efficiently locate and purchase knowledgeComputational Resources Market: The ability to rent and rent out forms of computational resources (CPU, disk, etc) allowing large-scale computations to take place under cost and computational efficiencyDerivatives Market: Agoras will have a no-middleman peer-to-peer derivatives market and by that implement risk-free interest without any creation of new coins, using the concept of zero-delta portfolios.Agoras will be the coin of natural and artificial knowledge over the new online society that we are building. Agoras will represent all tradable knowledge and computational resources on the network while acting as the first monetary market to acquire risk-free interest without printing new money. Agoras' efficiency will allow us to have a well-priced derivatives market to allow hedging, price-stability, and risk-free interest.
