Register a Make ID

Every identity on Makechain is anchored to a wallet on Tempo — an EOA, smart wallet, or WebAuthn passkey. You connect your wallet, generate an Ed25519 keypair, and register on the onchain registry. The registry assigns a Make ID, binds it to your wallet address (owner_address), and relays a KEY_ADD message into the consensus layer. Registration costs gas, providing natural spam resistance. MID ownership is transferable onchain for social recovery and account migration.

The private key is generated locally and never leaves your machine. Deterministic signing — no nonce reuse risk.

KEY_ADD relayed into consensus

KEY_ADD message (relayed from registry)

{
  "type": "KEY_ADD",
  "mid": "?",
  "timestamp": "...",
  "body": {
    "public_key": "d4f7a2c8e1b3...9f0e6d2a8c4b",
    "scope": "OWNER",
    "owner_address": "0x742d35Cc6634...a2F8e01B"
  }
}

The registry event is relayed into the Makechain consensus layer as a KEY_ADD message. This is the bridge between the onchain registry and the protocol — validators learn about your key without querying the chain directly.

Add more keys

Once your account is active, you can register additional keys with different scopes.

}

AGENT keys can push commits and update refs but cannot manage collaborators or account settings. Ideal for CI/CD pipelines and AI agents.

Submit ACCOUNT_DATA messages

ACCOUNT_DATA — username

  "mid": 42,
  "timestamp": 1740000030,
  "body": {

ACCOUNT_DATA — bio

  "timestamp": 1740000030,
  "body": {
    "field": "bio",
    "value": "Building the future of decentralized code hosting"
  }
}

ACCOUNT_DATA uses LWW Register semantics — the most recent message by consensus order wins per (mid, field) conflict key.

What happened

1. Key generation — An Ed25519 keypair is generated locally. The public key is 32 bytes, the private key never leaves your machine. Ed25519 uses deterministic signing, so there is no nonce reuse risk.

2. Onchain registration — You submit a transaction to the Makechain registry contract on Tempo with your public key. The registry assigns a unique Make ID (uint64), binds your wallet as the owner_address, and emits an event. The gas cost prevents spam — every account has a real economic anchor.

3. Relay into consensus — The registry event is picked up and relayed into the Makechain consensus layer as a KEY_ADD message with OWNER scope and your wallet's owner_address. This is processed in the account pre-pass (Phase 1, serial) because it modifies shared account state.

4. Account live — After finalization (~300ms), your account exists in consensus state. You can now create projects, push commits, add collaborators, and verify external addresses. Your wallet can always add new Ed25519 keys, and MID ownership can be transferred onchain for social recovery.

Key scopes

Each account can have up to 50 keys. Keys are a 2P set — use KEY_REMOVE to revoke a compromised key. On a timestamp tie, remove wins.
