Blockchain reduces need for trusting intermediaries.
But blockchain elements also need reputation rating in order to be trusted.
Difficult to assess trust in entities using the smart contracts• prevent against bad actors
How can smart contracts evolve without a core legal infrastructure? • how can we build a crypto legal system that can
be trusted?
How can we trust data coming from oracles?
How can we create a reputation system that is secure against Sybil and tyranny of majority attacks?
How can we use crypto economic incentives to reward trustful parties and punish bad actors?

Mission & Solution
• Crypto-economic incentivized system that rewards domain specific knowledge and trust
• Secure against Sybil and Tyranny of the Majority Problems and other Attacks
• Interacting systems: • 1) Bench: User generated list of sub-tokens, representing trust/reputation/expertise in specific domains • 2) Experts: Pool of anonymous experts/participants who will stake their sub-tokens on relevant topics
• Root and Tree (linked lists) of posts/comments/judgements, where header of each list represents the domain/expertise. As used herein, a concrete system contains relatively static and permanent information as compared to a more dynamic system, a betting pool
• 3) Betting pool of reputation-staked bets from bench experts on forum posts. This connects the experts with the respective posts they have expertise in. • Result of bets promotes truth and domain-specific reputation.
• Entities/participants benefit from a transparent, fair, and predictable system that facilitates certainty of outcomes, security, and efficiency
• Society benefits from the advancement of trust, justice, and prevention of corruption on a global scale.
• Establish Trust in Crypto Community
• Autonomous decentralized platform that facilitates a framework for the evolution of verified reputation for anonymous or identifiable users, human or machine
