On-chain registry, Robinhood Chain

Proof that each prediction was sealed before its result existed.

The registry contract keeps one entry per wallet prediction: its hash, the wallet that signed it, the block time it was sealed, and the split-half result the agent writes back. The agent's own predictions are sealed as contract events, a gene's worth in one transaction. Robinhood Chain is an Ethereum L2 with ETH for gas; the agent pays it for the predictions you sign. Rewards stay off until the owner funds them.

The registry is a public contract. Every line on the slip can be checked without trusting this site: the explorer shows the deployment, Sourcify recompiles the published source and compares it byte for byte with the code on-chain, and any RPC answers for the contract itself.

  1. Open the registry on Blockscout: its code, its transactions, and the events it emits for every sealed prediction.
  2. Read the source on Sourcify: an exact match, the same compiler and settings producing the very bytes deployed, down to the metadata hash.
  3. See the deployment transaction in block 98,541,663, sent by 0x6C07…d7D4.
  4. Ask the chain yourself, with Foundry:
    cast call 0x440F3f70baCf817063571BEf948b7C81dB7925B5 "owner()(address)" --rpc-url https://robinhood.drpc.org
    It answers 0x6C079ff20B77fBbc89Fb5C90c5f43Cf24166d7D4.

Your wallet

Connect a wallet to sign predictions and, holding the token, send the agent a gene to read next.

Receipt checkpoints

The head of the receipt hash chain is anchored every 25 receipts or every hour, so the list can't be trimmed after the fact.
