The naming inspiration comes from the HTTP 402 status code. x402 is a decentralized on-chain payment protocol that does not require registration or third-party authorization, allowing users to pay for digital resource fees directly via API. This system is compatible with the Coinbase concept and Google Agent-Payment Protocol, meaning that the payment process will be more automated and standardized.
Masumi Network is built on Cardano, creating an environment for secure transactions and task automation between AI Agents. After integrating the x402 protocol, AI can automatically complete payments and resource exchanges, promoting a truly trustless and autonomous smart economy.
Ouroboros Leios launched by IOG has moved from theory to implementation stage, and is an upgraded version of the current Ouroboros consensus. The goal is to optimize transaction throughput and network scalability, laying a solid foundation for large-scale AI payments and real-time interactions.
x402 and Leios enhance the payment and consensus layers, while Masumi Network promotes application transformation, collectively advancing the synchronized enhancement of Cardano ecosystem technology and market value. Additionally, the entry of ADA into the US crypto ETF showcases its position as a long-term mainstream asset.
With the technological updates, Cardano is no longer just a smart contract platform, but a collaborative infrastructure that supports the cooperation of AI agents. In the future, AI can automatically purchase computing power, subscribe to data, and even independently complete task settlements, creating a sustainable and operational smart economy.
