I haven't used Bisq in a minute, but it's very cool to see it getting polished up a little. Here's a way to let two trading partners agree on which price oracle they want to trust.

Bisq pricenodes serve market reference prices over Tor but do not sign their responses. This script periodically fetches prices from a pricenode and publishes them as signed Nostr events, creating a verifiable trail that trading parties can reference to agree on a price.

Two parties trading P2P can use these attestations to agree on a reference price:

Both parties trust the bot's public key, not each other or any relay.

> Two parties trading P2P can use these attestations to agree on a reference price:
> 
> 1. **Alice** publishes an offer: "selling BTC at market price + 7%"
> 2. **Bob** wants to accept. He queries the bot for the latest attestation, gets event `abc123` with USD price 62,610
> 3. **Bob** sends a TakeOffer to Alice including event `abc123` as the price reference. The agreed price is 62,610 * 1.07 = 66,992 USD
> 4. **Alice** fetches event `abc123` from any relay, verifies the signature, timestamps, and confirms the price
