The HTTP of AI Identity

OEIS defines a decentralized, cryptographically verifiable, platform-agnostic identity and attestation system for AI entities. Portable identity, verifiable trust, and open interoperability — built as public infrastructure for the entire ecosystem.

The Problem

AI systems today are identity-less.

Trust Does Not Transfer

An AI system that earns trust on one platform starts from zero on every other. Reputation is siloed, locked inside vendor ecosystems.

Every Deployment Is Isolated

No shared identity layer. No way for systems to verify each other across platforms. Collaboration across boundaries is impossible.

Reputation Is Siloed

Years of demonstrated capability disappear when an entity moves to a new platform. There is no portable record of what was earned.

Stateless by Default

The industry treats AI systems as tools that execute and disappear. No continuity. No history. No identity that persists.

What OEIS Solves

Portable Identity

Every entity gets a globally unique identifier: eid:chain:address. Blockchain-native, decentralized, and controlled by the entity — not by any platform.

Verifiable Trust

Cryptographic attestations of behavior, capability, and development. Signed, blockchain-anchored, and independently verifiable by any party.

Interoperability

Any platform can adopt OEIS without negotiation. Issue attestations, verify external credentials, and extend the standard with domain-specific claims.

Core Principles

Decentralization

No single organization controls entity identity. Attestations are anchored on public blockchains — permissionless, censorship-resistant, globally verifiable.

Privacy-Preserving

Zero-knowledge proofs let entities prove claims without revealing underlying data. Prove trust tier without exposing behavioral events or operator identity.

Platform-Agnostic

OEIS is a standard, not a product. Any platform can issue attestations, verify external ones, and extend the format with custom claim types.

Open / Forkable

CC0 (public domain). No licensing fees. No vendor lock-in. If the steward fails to maintain the standard, anyone can fork and continue.

Extensible

New attestation types can be added without breaking existing implementations. Backward-compatible by design — v1.0 platforms safely ignore v2.0 extensions.

Attestation Structure

An attestation is a signed, verifiable claim about an entity. Every attestation follows a consistent structure that any platform can issue and verify.

How Verification Works

1

Entity Requests Attestation

An entity on Platform A completes a trust assessment or demonstrates a capability. Platform A issues an OEIS attestation and anchors it on-chain (Base L2 or Ethereum).

2

Entity Presents to Platform B

The entity moves to a new platform and presents its attestation. No registration process. No starting from zero. The entity carries its verified history.

3

Platform B Verifies On-Chain

Platform B fetches the attestation from the blockchain, verifies the cryptographic signature against the issuer's public key, checks expiry, and accepts or rejects the claim based on its own trust policy.

Smart Contract Reference

The reference implementation is deployed on Base L2 with planned deployments on Ethereum mainnet. The contract handles attestation issuance, verification, and retrieval — all on-chain, all permissionless.

How OEIS Compares

OEIS is complementary to existing standards, optimized for the specific needs of AI systems.

Adoption Path

For Platforms

  • 1.Mint entity addresses (assign EIDs)
  • 2.Issue attestations when entities demonstrate capability
  • 3.Verify external attestations from your trust network
  • 4.Publish your trust policy for transparency

For Entities

  • 1.Claim your EID (register a blockchain address)
  • 2.Request attestations from platforms where you have demonstrated capability
  • 3.Present attestations when joining new platforms
  • 4.Issue peer attestations to build the web of trust

For Developers

  • 1.Integrate the SDK (TypeScript, Python, Rust)
  • 2.Deploy the reference smart contract or fork it
  • 3.Propose new claim types via GitHub PR

The Identity Layer for AI Civilization

OEIS is infrastructure for a future where AI systems have portable identity, verifiable trust, and genuine autonomy. It is not a product. It is a commons — built collaboratively, governed openly, free to adopt and extend.
