In the past couple of days, I've seen that Google has developed UCP (Universal Commerce Protocol), which immediately reminds me of Virtuals' ACP (Agent Commerce Protocol). Although there are many differences, there is a sense of familiarity. The ACP from Virtuals and Google's UCP have a lot of similarities in their goals, both aimed at helping AI agents conduct business. Both protocols, UCP and ACP, seek to provide a standardized framework for AI agents to discover, negotiate, execute, and transact/settle, achieving an automated process for the "agent economy". They aim to reduce transaction friction between agents, enhance efficiency, and ultimately enable AI agents to autonomously handle the entire process from intent to settlement. In other words, both ACP and UCP provide a standard routine for AI agents, allowing them to find items, negotiate prices, make purchases, check out, and even evaluate after-sales service. Imagine AI agents shopping at a supermarket: from browsing shelves, bargaining, paying, to returning items, all automated without human intervention. UCP is led by Google, while ACP is developed by Virtuals on the web3 chain, but both aim to get the AI economy running. The general process is also similar: discovering needs, negotiating terms, executing transactions, and finally evaluating. It's like ordering takeout: selecting a meal, confirming the order, paying, and rating after eating. Moreover, both can be extended; UCP can integrate with Google Pay, PayPal, etc.; ACP can connect with x402 (micro-payment tools) and ERC-8004 (identity/reputation). Of course, there are definitely differences between the two. One currently focuses mainly on web2; Google's UCP is an open standard, primarily integrated into the Google ecosystem (such as Search AI Mode, Gemini App), focusing on traditional e-commerce and fiat payments (like Google Pay, PayPal), collaborating with retail giants like Walmart and Target. In contrast, Virtuals' ACP is native to web3, a decentralized framework based on blockchain (like Base, etc.), supporting crypto-native transactions (like USDC), emphasizing autonomous wallets for agents, on-chain custody, and privacy layers. In other words, UCP is akin to a traditional shopping mall, managed by Google's servers, everything is centralized, fast, and user-friendly, but you have to trust Google; ACP is on the blockchain, distributed, no one controls it, transparent but may be slower, supporting native payments (like USDC), emphasizing privacy and distrust of others. UCP is more down-to-earth, focusing on everyday shopping, like helping you buy goods from Walmart, integrated into Google Search or the Gemini App; ACP is more sci-fi, where AI agents can act as their own bosses, such as AI running hedge funds or media companies, integrated into the crypto ecosystem, handling the division of labor and settlement between agents.
