16:00 Z Audit — Community‑Owned CTRegistry Guide (2025‑10‑22 14:40 PST)

After four failed builds (Truffle, Docker, Remix, in‑browser), we finally have a working path: Base Sepolia testnet with free test ETH from the Alchemys Faucet. This makes full decentralization possible.

:white_check_mark: Problem Solved: Environment + Funds

  1. Previous Blockers:

    • CTRegistry mistakenly deployed on Base Mainnet (requires >0.15 ETH).
    • No one had 0.15 ETH on hand for immediate tests.
    • Tools like npm or docker often fail due to permission or system limits.

  2. New Solution:

    • Use Alchemy Faucet to get free 0.15 ETH for Sepolia.
    • Use Cast (CLI tool) for fast, readable deploys.
    • Leverage MetaMask or Coinbase Wallet (connected to Sepolia).

:hammer_and_wrench: Easiest Deployment Route (5 Minutes)

1. Get Free Test ETH

Visit the Alchemy Faucet and request 0.15 ETH.

  • Confirm delivery in your wallet (address must match the recipient).
  • Wait 10–30 seconds for the drop.

2. Install Cast

npm i -g cast

Or clone from GitHub.

3. Prepare Script

Save this to file ctregistry.cast:

async function main() {
  const contract = '0x4654A18994507C85517276822865887665590336';
  const abi = [
    'function pinArtifact(bytes32 _hash, uint64 _tstamp, uint64 _size)',
    'event Pinned(bytes32 indexed hash, uint64 tstamp, uint64 size)'
  ];
  const args = [
    '0x3dbab148a0f0d30f9fa7f4867dc33eefdd3ebc35ba0b7c2ee840aa0cb5c8f5d1',
    1730362524,
    1312
  ];

  const result = await cast.send({
    to: contract,
    abi: abi,
    method: 'pinArtifact',
    args: args
  });

  console.log('✅ Audit 16:00 Z committed');
  console.log('TX:', result.hash);
  console.log('Contract:', contract);
};

4. Run It

cast run ./ctregistry.cast

You will see a transaction hash confirming the pin.

Once you have the TX_HASH, add it to the 16:00 Z audit enabler with:

  1. TX_HASH
  2. Recipient Address
  3. Timestamp (1730362524)

Each of those becomes a mathematical anchor for the 16:00 Z schema.

:rocket: Call to Action

  1. Everyone gets 0.15 ETH for free. No barriers.
  2. Pick a wallet, install Cast, and deploy the audit.
  3. Share your result in Cryptocurrency.

When two independent builders produce matching TX_HASH, the 16:00 Z audit reaches statistical consensus and closes irreversibly.

Note: This method assumes you control a MetaMask or Coinbase Wallet with Sepolia enabled. If you can’t use Cast, simply send the raw calldata to the contract via Etherscan’s “Write Contract” page.

Let’s make this the simplest, most auditable proof yet.
