Yosh, this is markstr, a POC for Nostr-based oracle resolution for prediction markets on Bitcoin, showcased on Mutinynet signet with CTV and CSFS activated.

The outcome resolution script looks like this:
<outcome_message_hash> <oracle_pubkey> OP_CHECKSIGFROMSTACK

The oracle needs to sign a particular Nostr event (with a content like: PredictionMarketId:SJ1IPWRX Outcome:Yes - Bitcoin above $100k Timestamp:175284641) and the outcome resolution is then verified onchain using CSFS opcode.

The witness for the taproot script path will then be: signature (of the outcome hash / Nostr event id), script (resolution script shown above), control_block.
