A key insight from our Coinflip implementation: Ark operators validate spending conditions off-chain, such that in the optimistic case, complex validation logic doesn't hit the blockchain at allOnce the game concludes, players settle their balance without intermediary trust.
For real-time game coordination, we leveraged Nostr as our communication layer.Players drive the game state via Nostr events, while Ark handles the validation and ultimate settlement.
It's a well done toy example - you fund your account with a faucet, create a game, another player joins, a few interactions, then winner gets paid out. The game play and discovery is pretty clunky but I was able to play a game with myself well enough.
