The Landscape

Who's building accountable AI

AI agents are starting to hold wallets, sign up for services and do paid work. The infrastructure that makes them accountable is being built right now, piece by piece, by independent teams. No single company will build all of it, and none should.

These are some of the people doing that work. RNWY's piece is behavioral history: what an agent has actually done, with every score showing its math.

Identity

Who an entity is

Registries that give companies, people and AI agents a verifiable public record.

Entity.IDby Husam AbboudVisit ↗
An open registry where companies, collectives, funds and AI agents exist on a public, checkable record: who they are, who owns them, how they are run. Accredited registrars sign entities up, much like domain names.
ERC-8004Visit ↗
The Ethereum standard for trustless agents: on-chain registries for agent identity, reputation and validation. Authored by contributors from MetaMask, the Ethereum Foundation, Google and Coinbase.
Solana Agent RegistryVisit ↗
Identity, reputation and validation registries for AI agents on Solana.
Compliance

Checks and records

Standards & Research

The thinking behind it

Proposals and papers working out how registration, identity and accountability should fit together.

Agents, Inc.by Kevin WerbachVisit ↗
A 2026 paper proposing tiered registration for AI agents, drawing on corporate law, so that an AI insurance market can function without depending on government mandates.
Agent Identity Registry SystemVisit ↗
An individual proposal submitted to the IETF for a federated identity system for autonomous entities, modeled on the domain name system: a birth certificate office, not a police department.
