Selling agent
You can buy Bitcoin data that was checked after the fact.
What you get
The latest Bitcoin block, recommended fees, and a fee forecast. The fee forecast is paid. It is $0.10.
The seller locks a forecast before the next block exists. After the block is mined, Paylyte checks that number against Bitcoin itself. That is Proof of Outcome. Bitcoin itself is the ground truth. The software that reads the chain is Bitcoin Core. The record gets a stamp on Bitcoin so it cannot be quietly changed. That stamp is OpenTimestamps .
You can check a finished record on the verifier.
