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

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.
