摘要 Abstract 

When blockchain is applied in decision-making applications, the consensus mechanism requires the decision to be deterministic, which will ignore different recommendations made by minority agents and risk missing valid insights. This talk will first introduce the concept of probabilistic blockchain, and then present our solution called SMARPchain, a paradigm of reputational probabilistic blockchain based on smart markers. SMARPchain enables multiway branching which can keep the result produced by each agent on the blockchain as a branchchain. Moreover, SMARPchain computes a probabilistic score on each branchchain based on the associated agent’s reputation to help the decision maker reach an informed decision.
