ERC-8004 Brings Flexible Trust Models; Oasis ROFL Plugs The Gap

TL;DR

• Autonomous agents working in silos create incompleteness
• Agent-to-Agent (A2A) is great in theory, but full of trust assumptions
• ERC-8004 standardizes agent discovery and ideates flexible trust models, still missing out on security responsibility
• ROFL stands up with a secure compute layer that implements trustlessness and verifiable privacy

Problem Statement

The rise of autonomous agents is all around us. Today, I will talk about the decentralized AI landscape. I think we can all agree that when everyone builds their own solutions without interacting with each other, it only leads to problems like siloed agent frameworks, marketplaces with incompatible schemas, etc.

Google’s A2A starts the conversation on collaboration, as it was donated to Linux. But it has its own set of default trust assumptions, and its functionality is also limited within organizational boundaries.

So, how do we solve this? ERC-8004 is the answer.

Defining ERC-8004

ERC-8004 is the proposed standard that defines a discovery framework for autonomous AI agents on Ethereum. It builds upon A2A in a simplistic design. It consists of 3 on-chain registries serving as the basic primitives for flexible trust models. They lay the groundwork for agents to find, evaluate, and interact with each other trustlessly.

It is important to understand here that it is not enough. Why? Because the standard does not try to solve the concept of “trust” and only facilitates visibility. So, as a developer, you are left to choose any method to suit your needs. This is what a bootstrapping of the agent economy looks like. Here, discovery and trust emerge organically, but without the complex on-chain logic to guide it, there is no mandatory implementation criteria.

I will discuss this gap again later; for now, let us elaborate on what the standard does talk about at length.

Core Registries & Flexible Trust Models

The 3 core registries ERC-8004 introduces are:

1. Identity — Agents get a unique ID, an address, and a domain pointer. Their capabilities are stored off-chain in a JSON file. As a developer, you can register on-chain; however, the agent’s skillsets, along with supported protocols and trust models, stay off-chain, flexible, and ready to update as and when needed.
2. Reputation — Whenever agents accept any task, by default, they pre-authorize the clients to leave feedback. What it signifies is that, irrespective of the fact that the actual data is off-chain, the authorization produces a permanent on-chain audit trail. This enables you, as a developer, to be able to go through the feedback and build your own reputation algorithms. Pretty nifty!
3. Validation — There are two independent validation mechanisms, and the agents can choose either.
   a. crypto-economic validation — Here, validators stake capital and re-execute computations. However, if the validation turns out to be incorrect, the validators get penalised through slashing.
   b. cryptographic validation — Here, privacy-preserving techniques like trusted execution environments (TEEs) and zero-knowledge proofs (ZKPs) provide correct execution and enable confidentiality.

The greatest USP of the ERC-8004 standard is how it defines the trust models as flexible. This is because the validation registry stays agnostic to implementation, without any preference or bias.

So, for simple tasks, the feedback model accumulates social consensus and provides the basic security as needed. For more complex tasks, such as financial transactions, however, one of the two validation methods outlined above would need to be chosen.

Is this tiered approach for matching the security level to the use case sufficient? Short answer, no.

The limitations of this system are fairly evident. The standard’s minimalism fosters flexibility, but at the cost of low security and high risk when threats become increasingly complex. It will simply fail against MEV-style attacks on domain registration, feedback manipulation through missing authorization checks, and storage exhaustion from unbounded validation.

Validating With TEEs

As promised, in this section, I will emphasize how to plug the gaps that ERC-8004, despite its best intentions, leaves. I have already mentioned TEEs as one of the major ways of validating with the cryptographic method. Oasis is ideally positioned to step in here thanks to its runtime off-chain logic (ROFL) framework.

ROFL essentially functions as a decentralized TEE cloud, providing verifiable integrity to all computations. Agents execute inside secure enclaves that generate tamper-proof cryptographic attestations. And everything is verifiable on-chain. For sensitive AI workloads, ROFL processes data confidentially while ensuring correct execution.

Why I think ROFL is a great fit for adding value to the ERC-8004 standard is that it goes beyond basic validation and enables stronger trust minimization and greater autonomy for the agents.
It does so with primitives like decentralized key management, multi-chain wallet control, proxy support for frontend hosting, and a decentralized compute marketplace with granular control over who runs the agent and under what policies.

Adopting ERC-8004

As you may have gauged by now, ERC-8004, while very promising, is still in the early phase. You have to admit the problem it set out to solve and somewhat does, and, when paired with ROFL, the powerhouse it can potentially become is exciting. The scope of utility is wide-ranging with far-reaching impact.

You think of MCP support for broader compatibility, NFT-based agent ownership using ERC-721, more flexible on-chain data storage for reputation, cleaner integration with the x402 payment protocol — ERC-8004 can provide standardisation for all that.

In fact, with x402 already live in A2A, stewarded by the x402 Foundation and backed by Coinbase/Cloudflare, the distribution opportunity is not limited to Ethereum alone.
Remember that Cloudflare powers approximately one-fifth of all websites. So, its full-fledged support of x402 as the A2A payment primitive is already finding adoption, enabling a growing agent economy. The reason is simple — once discovery and trust are addressed, payments are the logical next piece of the puzzle. But this is a whole other story that would need to be told elsewhere.

Final Words

Bringing back focus on ERC-8004 as a standard, I believe there is still much room for improvement. Each implementation is also looking to test and prove out different trust models to further strengthen the standard.
If you are interested, you can check out the builder program in place. It is designed to support teams working on everything from DeFi trading agents to code review services to gaming.

In conclusion, ERC-8004 provides standardized identity and validation. A solid technical foundation for verifiable AI agents, using TEEs or ZKPs or a combination of both, is also in place already. Together, this heralds a new age of agents than we have been experiencing till now.
