Summary
- What is new: The paper introduces novel mechanisms and strategies integrating blockchain technology into the multi-agent multi-armed bandit problem, focusing on maintaining security against malicious participants and ensuring privacy.
- Why this is important: Addressing how to secure cumulative rewards for honest participants in a decentralized blockchain environment where some participants may be malicious.
- What the research proposes: A new system using a pool of validators, a novel consensus mechanism, a UCB-based strategy requiring less information, and an interaction-incentive mechanism to encourage participation while ensuring security and privacy.
- Results: The paper theoretically proves that the regret of honest participants is limited, achieving consistency with traditional multi-agent multi-armed bandit problems, even in the presence of malicious players.
