The BNB Chain developer team stated that as the ecosystem continues to expand, applications need to share rules to achieve seamless collaboration. To this end, BNB Chain launched the BAP (BNB Application Proposal) mechanism, allowing developers to reach consensus on application-layer standards such as NFT utility, AI agent behavior, and identity specifications without touching the consensus layer or EVM. The official team also introduced the first proposal, BAP-578, the Non-Fungible Agent (NFA) token standard. This standard proposes that an NFA is an AI-driven, on-chain asset capable of autonomous operation and possessing capabilities such as wallet holding, transaction execution, recording behavioral history, and operation across multiple dApps. BAP-578 is considered one of the infrastructures of the "agent economy," aiming to promote the flow and collaboration of AI agents within the BNB Chain ecosystem according to unified standards. BNB Chain points out that BAP is designed to be community-driven; developers can participate in reviewing BAP-578, providing feedback, or submitting new BAPs to collectively shape the application-layer standard system.
