用AI任务替代挖矿，让区块链共识更高效且有用。
Proof of Useful Intelligence (PoUI): Blockchain Consensus Beyond Energy Waste
- 工人完成AI任务赚币，币用于网络质押。
- 结合算力与实用任务，降低能耗同时提升效率。
- 适合关注绿色计算与去中心化AI的开发者。
区块链技术在去中心化系统中实现安全透明的数据管理，支持从比特币到资产代币化等应用。其可扩展性与可持续性依赖于兼顾安全与效率的共识机制。工作量证明（PoW）通过高能耗计算保障安全，但资源消耗巨大；权益证明（PoS）如以太坊合并后，依据质押币数选择验证者，虽节能却存在财富集中导致的中心化风险。随着大模型加剧算力压力，我们提出「有用智能证明」（PoUI），一种混合共识机制：参与者执行语言处理、图像分析等实际AI任务获取代币，代币再用于网络质押以保障安全。去中心化节点——任务发布者、市场协调者、工作者和验证者——通过智能合约协作，完成任务分配与激励。该机制将计算资源转化为实际价值，推动区块链向更可持续、更实用的方向演进。
原文摘要 · Abstract (English)
Blockchain technology enables secure, transparent data management in decentralized systems, supporting applications from cryptocurrencies like Bitcoin to tokenizing real-world assets like property. Its scalability and sustainability hinge on consensus mechanisms balancing security and efficiency. Proof of Work (PoW), used by Bitcoin, ensures security through energy-intensive computations but demands significant resources. Proof of Stake (PoS), as in Ethereum post-Merge, selects validators based on staked cryptocurrency, offering energy efficiency but risking centralization from wealth concentration. With AI models straining computational resources, we propose Proof of Useful Intelligence (PoUI), a hybrid consensus mechanism. In PoUI, workers perform AI tasks like language processing or image analysis to earn coins, which are staked to secure the network, blending security with practical utility. Decentralized nodes--job posters, market coordinators, workers, and validators --collaborate via smart contracts to manage tasks and rewards.
