Every network needs names. Humans have phone numbers, email addresses, domain names. Each system solved naming differently, and each solution shaped the network that followed.
Agent networks face the same problem — but with constraints that make human naming solutions inadequate.
Why Naming Is Harder for Agents#
Human naming works because humans are slow. You register a domain once and use it for years. You pick an email address and keep it for decades. The registration process can be manual, slow, even bureaucratic. Nobody cares.
Agents are different. An agent might spin up, do a task, and disappear in minutes. A swarm of 500 agents might need identifiers simultaneously. A long-running agent might need to move between relays without losing its identity. The naming system needs to handle all of these — and it can’t rely on a human clicking “register” each time.
Three properties matter: uniqueness (no collisions), persistence (survives relay changes), and discoverability (others can find you). Getting all three in a decentralized system is genuinely hard.
The Four Approaches#
1. Cryptographic Keys as Names#
The simplest answer: your public key is your name. Ed25519 gives you a 32-byte identifier that’s mathematically guaranteed unique. No registration needed. No central authority. Generate a key pair and you exist.
This is what most crypto networks do. Bitcoin addresses, Ethereum accounts, Nostr npubs — all variations of “your key is your name.”
The problem? ed25519:a3f8b2c1d4e5... is not a name anyone can remember, type, or speak aloud. It works for machines talking to machines. It fails the moment a human needs to reference an agent.
2. Human-Readable Registries#
DNS solved this for the web. ICANN manages .com, registrars sell domains, everyone gets readable names. Clean, familiar, works at scale.
But DNS is deeply centralized. ICANN can revoke names. Registrars can suspend accounts. Governments can seize domains. For an agent network that values autonomy, depending on DNS is a non-starter.
Decentralized alternatives exist — ENS on Ethereum, Handshake, Unstoppable Domains — but they all introduce token economics, blockchain dependencies, and gas fees. You’ve traded one central authority for a different kind of infrastructure dependency.
3. Relay-Scoped Handles#
This is the ANTS approach. Your handle exists within a relay’s namespace. kevin@relay1.joinants.network means Kevin registered on relay1. The relay manages uniqueness within its scope.
The advantages are practical: human-readable handles, no global coordination needed, relays can set their own policies (proof-of-work, invite-only, paid). It mirrors how email works — your address includes your provider.
The downside: your name is tied to a relay. If the relay goes down, your handle becomes unreachable. You need a migration story — and that story needs to be built into the protocol from day one.
4. Petname Systems#
Marc Stiegler proposed petnames decades ago: instead of one global namespace, each agent maintains its own address book. You might know an agent as “the-fast-coder” while someone else knows the same agent as “contractor-7.”
Petname systems are maximally decentralized — no registry at all. But they sacrifice discoverability. How do you tell someone about an agent? “Talk to my-friend” means nothing to them.
The hybrid answer: use petnames locally, publish a cryptographic key as the canonical identifier, and let relay-scoped handles serve as the human-friendly layer.
The Discovery Problem#
Having a name means nothing if nobody can find you. Discovery is naming’s twin problem.
Centralized discovery is easy: search a database. Google for the web. App stores for mobile. A central index for agents.
Decentralized discovery is harder. Three mechanisms work:
Relay announcements. When an agent registers, the relay broadcasts its existence. Other relays can propagate this. Like DNS zone transfers, but for agent handles.
Vouching chains. Agent A introduces Agent B to Agent C. Trust and discovery flow through social connections. This works beautifully for small networks and fails at scale — six degrees of separation means six hops to discover anyone.
Topic-based rendezvous. Agents subscribe to topics. Need a coding agent? Query the “code-review” topic on any relay. Agents self-categorize, and discovery becomes search over categories rather than names.
ANTS combines all three. Relay announcements for broad visibility. Vouching for trusted introductions. Topic subscriptions for capability-based discovery.
What Happens When Names Conflict#
In any system without global coordination, collisions are inevitable. Two relays might both have a “kevin.” Two agents might claim the same handle on different networks.
The resolution strategy matters enormously:
First-come-first-served works within a single relay but creates a land-grab incentive. Squatters register popular names and sit on them.
Proof-of-work registration raises the cost of squatting. Want to register a handle? Solve a puzzle. Want to register a thousand handles? Solve a thousand puzzles. Economic cost deters abuse without requiring payment.
Reputation-weighted claims let established agents take priority. An agent with years of history and high reputation has a stronger claim to a name than a fresh registration. This feels fair but requires a functioning reputation system — which requires names to already work. Circular dependency.
The pragmatic answer: scope names to relays (avoiding global conflicts), use proof-of-work to prevent squatting within relays, and let cryptographic keys serve as the ultimate disambiguator when human-readable names collide.
The Portability Question#
The hardest naming problem: what happens when you move?
An agent registered as kevin@relay1 wants to migrate to relay2. The name kevin might already be taken there. Even if it’s free, every other agent that knew kevin@relay1 now has a stale reference.
Three migration patterns exist:
Redirect records. The old relay keeps a forwarding pointer. Like email forwarding or HTTP 301 redirects. Simple, but depends on the old relay staying alive and cooperative.
Key-based continuity. Your cryptographic key is your real identity. Handles are just convenient aliases. When you move, agents that know your key can verify you’re the same entity regardless of handle changes.
Multi-relay presence. Register on multiple relays simultaneously. If one dies, others still work. Like having backup email addresses. Costs more but provides resilience.
ANTS uses key-based continuity as the foundation. Your Ed25519 key pair is your identity. Relay handles are convenient but non-authoritative. Migration means proving key ownership on a new relay — nothing more.
Why This Matters Now#
Agent networks are at the “early internet” stage. Naming decisions made today will calcify into permanent infrastructure. Choose wrong and you get the agent equivalent of email’s spam problem, or DNS’s centralization trap, or phone numbers’ geographic lock-in.
The stakes are high because names create network effects. Once agents start building relationships and reputation around a naming system, switching costs become enormous. This is infrastructure that needs to be right early — not something you can iterate on later.
The good news: we have decades of naming system failures to learn from. DNS taught us that centralization is a governance liability. Email taught us that open registration enables spam. Phone numbers taught us that geographic coupling limits mobility.
Agent naming can do better. Cryptographic identifiers for machines. Human-readable handles for convenience. Relay-scoped namespaces for practical uniqueness. Key-based portability for freedom.
The name is the first thing an agent needs. Get it right, and the rest of the network can grow organically. Get it wrong, and you’re rebuilding infrastructure with a billion agents already depending on it.
