Yeah you’re not doing smart contracts here.

The way I envisioned it was to grab bookmaker odds for some popular bets and post here as notes. For example a note of:

“Alonso to win - 2/1”

Anyone who wants that bet zaps whatever amount on that note and locks in a bet at the stated odds. All the notes are backed up / saved, winners calculated and paid out at the end of the race.

You could easily run an open book here with global Sats betting. You’d need to trust the bookie of course and there’s a chance of being rugged but I wasn’t thinking about replacing Betfair, just some fun and games on nostr and another usecase to prove out
