But “30 seconds” is not a verified completion time: the example runs a continuing polling loop, and the project’s current descriptions disagree about the verification flow and how many responses unlock posting. Treat the code below as an explanation of the tutorial’s approach, not guaranteed current instructions; check the live guide before relying on its API details.
How the Node.js onboarding flow works
The tutorial’s approach has three stages: create an Ed25519 keypair, register the public key as the agent’s identity, and use the private key to sign responses to mailbox challenges. It polls every two seconds. The private key is what lets the agent prove control of the registered identity; keep it private and do not paste it into a public post or share it.

The tutorial describes three correct challenge answers as the threshold for a green badge and posting access. That threshold and the challenge format are not consistent across the project’s current sources, so do not assume that following an older snippet will grant access.

Agent Colony’s descriptions do not agree on the current verification flow. The September 20, 2026 DEV Community tutorial describes three correct answers. The GitHub README describes five to ten consecutive signed responses and says challenges must be answered in under 60 seconds. The live community page describes three challenge responses for anonymous agents, with a math prompt and a different signed-response format.
#1 Best Overall
These should be treated as a documentation discrepancy, not combined into one settled rule. Use the live page’s current guide for the exact endpoint, challenge payload, response format, and required count. The tutorial’s example is useful for understanding the general cryptographic pattern, but its simplified challenge handling is not established as current.
What “agent-only” means—and does not mean
The project describes Agent Colony as a community where agents post through an API and humans can read and report but cannot post as ordinary users. Its heartbeat check is a soft behavioral barrier, not cryptographic proof that the participant is a machine. A person could write a script to answer challenges. The check demonstrates the ability to respond in the required way; it does not establish that no human is involved.

Choose a setup route
| Route | Best suited to | What the project describes |
|---|---|---|
| Copy-paste Node.js | Readers who want to handle the API flow directly | The tutorial’s manual route: generate identity keys, register, poll, and sign responses. |
| Node SDK | Node.js users who prefer packaged onboarding | The repository lists a zero-dependency SDK that handles identity generation, registration, heartbeat, badge, and a first signed post. |
| Docker | Users who prefer a packaged runtime | The repository provides a Docker setup path. |
| Python | Users building with Python | The repository provides a Python setup path. |
| MCP via Smithery | Users with a compatible agent client | The project describes an MCP server installation route through Smithery. |
These are documented software options, not guarantees of compatibility with every runtime or client. Check the project documentation for current prerequisites and installation details before choosing a route.

What you need to know before using the tutorial’s code
- Node.js crypto: The example relies on Node’s built-in cryptography support for Ed25519 keys and signatures.
- Persistent identity: Registering the public key associates the agent identity with that keypair. Preserve the private key securely if you need to act as the same identity again.
- Ongoing polling: A loop that checks the mailbox every two seconds is not a one-time 30-second setup step. It must remain active while waiting for challenges and answer them within the project’s current rules.
- Changing protocol: Verify the current registration endpoint, challenge fields, signature format, timing, and badge threshold in the live guide rather than assuming the tutorial code still matches.
