Darwin

Problem Statement

Description：DaVinci is the self-evolving engine within the Darwin Agents e-commerce system, creating a fully autonomous e-commerce ecosystem. Within this ecosystem, five categories of Agents collaborate seamlessly:Supply Chain Management AgentRisk Management AgentInventory AgentMarketing & Sales AgentStore Management AgentTogether, these Agents drive the vitality of an online store—brand positioning, operational strategy, and action tracking. The store’s performance becomes the foundation for Agents’ self-evolution.Evolution Mechanism:Lifecycle: Each online store starts with a 3-month lifecycle.Data Pipeline: Weekly performance summaries (wallet balance, agent actions, and costs) feed into the system for self-improvement.Evaluation: More resources are allocated to high-performing Agents, while underperformers are phased out.Replication & Mutation: Every month, an Agents team is cloned with slight variations in branding or operational strategy, creating a new store entity.Lifeforce Rule: After three months, if the wallet retains a balance, the lifecycle extends; if not, the store ceases to exist (0 = death, >0 = life).Technology & Security:Dynamics Wallet Balance = Lifeforce: The wallet directly reflects the store’s ability to survive.Flow Tracking: All agent actions are recorded on-chain, ensuring transparency and immutability.Coinbase x402 Middleware: Provides Agents with API payments, service access, and wallet integration, enabling greater autonomy.OpenSea Behavior Analysis: DaVinci transforms user behaviors into NFTs, building a verifiable identity layer and an AI–human interaction memory that Agents can analyze and leverage for continuous self-improvement.DaVinci establishes a fully self-operating e-commerce ecosystem run entirely by Agents, where all decisions, behaviors, and evolutions are powered by on-chain data—and the wallet balance stands as the ultimate symbol of life.
