摘要：
本文提出一种新范式：生成式区块链，旨在通过结合交易生成与记录来变革传统区块链技术，而非仅关注交易记录。我们设计的核心是新型共识机制 Proof-of-Merit (PoM)，专为在交易记录前必须解决复杂问题的商业环境而设计。PoM 在统一的区块链系统内整合了交易的生成与记录，从根本上不同于主要记录现有交易的现有共识机制。我们在按需出行服务平台上演示了 PoM，其中解决复杂交易生成问题的任务被委派给独立问题解决者池。这些解决者生成交易，其解决方案基于价值被选出。获胜解决者随后将这些交易注册到区块链上并获得相应奖励。我们引入了去中心化控制参数 (DCP) 来平衡两个关键性能指标：效率和公平性。我们通过拼车场景说明了生成式区块链的适用性，其中匹配者（解决者）负责将乘客与司机匹配。我们使用基于智能体的仿真演示了 PoM 的性能和细微特性，探索如何找到最优 DCP 值以在生成式区块链中实现效率与公平的理想平衡。
英文摘要：
This paper proposes a new paradigm: generative blockchain, which aims to transform conventional blockchain technology by combining transaction generation and recording, rather than focusing solely on transaction recording. Central to our design is a novel consensus mechanism, Proof-of-Merit (PoM), specifically crafted for environments where businesses must solve complex problems before transactions can be recorded. PoM integrates the generation and recording of transactions within a unified blockchain system, fundamentally differing from prevailing consensus mechanisms that primarily record existing transactions. We demonstrate PoM on a ride service on-demand platform, where the task of solving complex transaction-generating problems is delegated to a pool of independent problem solvers. These solvers generate transactions, and their solutions are selected based on merit. The winning solvers then register these transactions onto the blockchain and are rewarded accordingly. We introduce a Decentralized Control Parameter (DCP) to balance two key performance metrics: efficiency and equity. The applicability of our generative blockchain is illustrated through a ridesharing context, where matchers (solvers) are tasked with matching riders to drivers. We demonstrate PoM's performance and nuanced properties using agent-based simulation, exploring how to find the optimal DCP value to achieve a desirable balance of efficiency and equity in a generative blockchain.
