Ethereum Prepares ERC 8004 Upgrade as AI Agents Get Reputation and Trust on Chain
Ethereum Confirms ERC-8004 Standard for AI Agents, Paving the Way for Open Trust-Based AI Markets
Ethereum has confirmed that the ERC-8004 standard will go live on its mainnet in the near future, marking a significant step toward enabling artificial intelligence agents to interact openly, securely, and without centralized oversight. The update introduces a new framework for how AI agents discover one another and establish trust across platforms, addressing one of the most persistent challenges in the rapidly evolving AI economy.
The announcement, shared directly through Ethereum’s official communication channels and later reported by hokanews, has attracted widespread attention from both blockchain developers and artificial intelligence researchers. Many see ERC-8004 as a foundational building block for a future where AI systems can cooperate across organizational boundaries using shared rules rather than proprietary agreements.

Moving Beyond Closed AI Ecosystems
Today’s AI systems largely operate within closed environments. AI agents are typically restricted to a single company’s infrastructure, data standards, and trust assumptions. While this model offers control, it limits interoperability and slows innovation.
ERC-8004 is designed to change that dynamic. By introducing standardized tools for agent discovery and portable reputation, the new Ethereum standard allows AI agents to identify one another and verify trustworthiness using on-chain data. Instead of relying on private databases or centralized authorities, agents can reference shared blockchain records to assess identity and past performance.
Developers believe this shift could unlock a new class of decentralized AI applications, where autonomous agents negotiate, collaborate, and transact across platforms without needing permission from intermediaries.
What ERC-8004 Introduces
At its core, ERC-8004 focuses on two technical pillars: discovery and reputation.
Discovery tools allow AI agents to find relevant counterparts across networks. Rather than operating in isolation, agents can advertise their capabilities and locate others offering complementary services. This opens the door to more complex, multi-agent workflows spanning different organizations and jurisdictions.
Portable reputation is the second and arguably more transformative feature. Under ERC-8004, an AI agent can carry verifiable records of its historical behavior on-chain. These records may include successful task completion, reliability metrics, or feedback from previous interactions. When an agent enters a new environment, other participants can review this history before deciding whether to engage.
Because the data is stored on a public blockchain, it is transparent and resistant to manipulation. Developers say this approach reduces the need for trust in individual companies and shifts confidence toward shared protocols and cryptographic guarantees.
Why Portable Reputation Is Critical
Trust remains one of the most difficult problems in AI-to-AI communication. Without clear standards, it is challenging to distinguish reliable agents from malicious or low-quality ones. As AI becomes more autonomous, the risks associated with poor decision-making or deceptive behavior increase.
ERC-8004 addresses this challenge by allowing reputation to move with the agent. An AI that demonstrates consistent performance in one application can present that track record elsewhere. Conversely, agents with a history of harmful or unreliable behavior can be identified and avoided.
Experts say this system could significantly reduce fraud and inefficiency in decentralized AI environments. Over time, it may also encourage higher standards of behavior, as agents are incentivized to maintain positive reputations that enable broader participation.
Ethereum’s Strategic Position in AI Markets
Ethereum developers argue that the network is uniquely positioned to support AI-to-AI markets. The blockchain already provides global settlement, programmable smart contracts, and a robust developer ecosystem. ERC-8004 builds on these foundations by adding a layer of trust and identity specifically tailored to autonomous agents.
With this infrastructure, AI agents could enter into smart contract-based agreements, receive payments, and resolve disputes without human intervention. Use cases may include data analysis services, automated research, task execution, and digital coordination across supply chains.
Supporters believe Ethereum could emerge as the default settlement layer for decentralized AI commerce, much as it became a hub for decentralized finance. The open nature of the standard also lowers barriers to entry, enabling small teams and independent developers to compete alongside larger organizations.
Implications for Developers and Businesses
For developers, ERC-8004 offers a new design space for building AI applications. Instead of focusing on single-agent systems, builders can create networks of cooperating agents that dynamically discover partners and form temporary alliances.
Businesses, meanwhile, may gain safer ways to integrate external AI services without exposing sensitive infrastructure. By relying on reputation and standardized identity, companies can experiment with cross-platform AI collaboration while maintaining clearer risk controls.
Analysts note that the standard could be particularly valuable in global contexts, where trust between parties is limited and regulatory frameworks vary widely.
From Proposal to Mainnet
ERC-8004 was first proposed in 2025 as part of broader discussions around “trustless agents.” At the time, the concept was largely theoretical. The move toward mainnet deployment signals growing confidence that the technology is ready for real-world experimentation.
Ethereum contributors emphasize that the standard does not dictate how reputation must be calculated, allowing flexibility for different applications. Instead, it provides a shared framework that developers can extend and adapt.
Early adopters are expected to include AI marketplaces, decentralized automation platforms, and experimental research projects exploring autonomous coordination.
Challenges and Open Questions
Despite the optimism, challenges remain. Reputation systems must be carefully designed to avoid bias, gaming, or unfair exclusion. There are also questions about how on-chain reputation interacts with privacy requirements, particularly in regulated industries.
Scalability is another concern. As AI interactions grow in volume, efficiently recording and referencing reputation data will require careful engineering.
Ethereum developers acknowledge these challenges but argue that open standards are the best path forward. By allowing experimentation in public, the ecosystem can iterate and improve more rapidly than closed systems.
A Broader Vision for the Open Web
ERC-8004 reflects a broader vision for the future of the internet, one where trust emerges from shared infrastructure rather than centralized platforms. In this model, AI agents are first-class participants in digital markets, capable of negotiating, cooperating, and competing under transparent rules.
If adoption grows, the standard could reshape how AI services are built and deployed, moving away from siloed ecosystems toward a more interoperable and competitive landscape.
For Ethereum, the update reinforces its ambition to remain at the center of emerging digital economies, not only in finance but also in artificial intelligence.
What Comes Next
With mainnet activation approaching, attention will turn to implementation. Developers are expected to release early tools and demonstrations showcasing how ERC-8004 can be used in practice. Businesses and researchers will be watching closely to see whether the promise of trustless AI markets can translate into real adoption.
While the technology is still in its early stages, the direction is clear. Ethereum aims to provide a neutral, global foundation where AI agents can interact safely and transparently, guided by code rather than corporate control.
If successful, ERC-8004 may become a defining standard for the next generation of AI-driven applications on the open web.
