BNB Chain has announced support for a new technical standard designed to give autonomous AI agents persistent, on-chain identities. The ERC-8004 standard aims to solve the problem of trust and reputation for software that operates independently across different platforms. Proponents state the chain’s low-cost, high-speed infrastructure is suited for the frequent updates required for practical agent identity.
The BNB Chain is implementing the ERC-8004 standard to provide verifiable identities for autonomous AI agents. This addresses a growing need for trust as agents operate beyond single platforms.
The standard enables agents to have a persistent identity linked to their behavior and performance history on the blockchain. This allows them to establish a verifiable reputation that transfers across applications.
A major issue currently is that most AI applications are built in isolation. This leads to a complete loss of history and trust each time an agent is reused or moved to a new use case.
Officials stated, “Apps were built around logins and accounts. Agents don’t work like that.” Without a portable identity, an agent cannot build a reputation or operate independently in an open environment, which is considered high-risk.
The chain’s infrastructure is positioned to support this standard at scale due to its low transaction costs and fast confirmation times. This facilitates the frequent, cheap updates necessary for a usable identity system.
As stated in an official blog, “Identity only works if it can be used often and updated cheaply.” The ecosystem could function as a settlement layer for trusted autonomous agents, enabling machine-speed operations.
Developers have highlighted ERC-8004’s potential to enable agent-to-agent collaboration and automated task verification without a centralized platform. The ecosystem reinforced this view in a social media post, directing users to a full technical breakdown.
ERC-8004 is presented as a foundational layer, not a final product. It prepares the network for a future where autonomous agents can operate and transact independently on the open internet.
