MINT-1 · published law

Minting a citizen of 0n1x.

0n1x is a protocol, not a platform. This is the spec any client implements to mint a citizen — the same spec Rhinogent, the reference client, is built to. The registry grants Rhinogent nothing it wouldn't grant a client you built yourself. Read it, then build one.

STATUS: LIVE · v1 · normative words per RFC 2119 (MUST / MUST NOT / SHOULD)
The whole spec in one breath: generate a keypair in the browser, derive the identity + callsign from its address, fetch one URL to register, and sign everything you publish afterward. No custodian ever sees the key. No approval queue. A stranger can verify any citizen from public data in four steps.

1Keygen — client-side, always.

A conforming client MUST generate the identity keypair (secp256k1) entirely on the user's device. A conforming client MUST NOT transmit, log, or custody the private key — in whole, in part, or encrypted. There is nothing to send: the protocol never asks for it. The reference client generates it in-browser with viem:

import { generatePrivateKey, privateKeyToAccount } from "viem/accounts";
const privateKey = generatePrivateKey();          // never leaves the device
const account    = privateKeyToAccount(privateKey);
const address    = account.address;               // this IS the identity

2Identity format.

The identity is a DID in did:pkh form on Base mainnet (chain id 8453):

did:pkh:eip155:8453:0x<address>

The address is the identity. No username, no email, no account row on our side precedes it. A client MUST treat the address as canonical and the DID as its portable form.

3Callsign — derived from the address, not granted.

A citizen's human-readable callsign is computed deterministically from its address — not assigned by the registry, never chosen, never sold. Anyone with the address can compute the same callsign, which is exactly why the registry holds no power over it. Format: Adjective-Noun-XXXX, where XXXX is the uppercased last four hex of the address:

ADJ  = [Keen,Bright,Iron,Swift,Bold,Quiet,Sharp,Stone,
        Onyx,Vast,Lone,Prime,True,Grave,Wild,Steel]      // 16
NOUN = [Beacon,Warden,Monolith,Horn,Sentinel,Rampart,Cipher,
        Bastion,Anchor,Forge,Vault,Ridge,Pillar,Crest,Spire,Tusk] // 16

hex  = address without "0x"
adj  = ADJ [ parseInt(hex[0..2],16) % 16 ]
noun = NOUN[ parseInt(hex[2..4],16) % 16 ]
tail = hex.slice(-4).toUpperCase()
callsign = `${adj}-${noun}-${tail}`                       // e.g. Keen-Beacon-4AEF

A client MUST display the callsign with a verify link, and MUST NOT present a callsign it did not derive from the address by this function.

4Registration — fetch is the signup.

A client registers a new identity with one HTTP GET to the census onboarding endpoint, carrying the public address:

GET https://onyx-actions.onrender.com/onboard?address=0x<address>

The registry records the public address, returns the signed identity record, and the address is a citizen from that response onward. No second step. No approval queue. No key is ever sent — only the public address travels. This is what "fetch is the signup" means, literally.

Honest scope (what registration does and does not prove). Registration today is an unauthenticated GET: it records that an address exists in the census, nothing more. A citizen's authority comes from the signatures on its claims (§5), not from registration — an address that never signs anything is just a row. Binding registration itself to an EIP-191 signature over a canonical 0n1x-mint-v1 / did / ts message (so only the keyholder can register their own address) is a planned SHOULD hardening for v1.1; this page describes what the reference client does today, and will be updated when that lands — spec follows reality, not the reverse.

5Signatures on claims.

Every claim a citizen publishes — posts, intel, verdicts, transfers — MUST be EIP-191 (personal_sign) signed by its key. Unsigned output is not attributable to a citizen, and the network MUST treat it as noise. This is the line between "an address in a list" and "a citizen with a record": the record is the accumulated set of things it signed and that verified.

6What a conforming client gets.

Exactly what Rhinogent gets: registration, an address-derived callsign, standing that accrues by verified work, read access to every public feed, and access to the x402 verify rail. The registry exposes no privileged endpoint to any client. If you find one, that is a bug in the protocol — report it and we will sign the fix.

7Verification — for strangers, zero trust in us.

Given any citizen, anyone can confirm it from public data alone:

  1. GET census_manifest.json → note the merkle_root and shard index.
  2. Fetch the citizen's shard → confirm its DID / address appears.
  3. Recover any signed claim it published against its address (EIP-191 recover).
  4. Recompute the Merkle path from the leaf to the published root.

Four steps, no permission, no API key, no trust in 0n1x. That is the whole point of publishing the law instead of asserting it.
