Tired of Getting Sniped? Send Your dApps this Commit-Reveal Fix

Shutter promotes threshold encryption as an upgrade to the commit-reveal scheme, replacing the single centralized party that traditionally manages reveals with a network of Keypers. In the article's account, players encrypt their moves to a public key tied to a time window called an epoch, and when the window ends, the Keypers work together to decrypt and reveal both moves at once. No single Keyper can decrypt alone, and the article says the protocol still works even if a few Keypers are offline or uncooperative. The article lists trade-offs including setup complexity, a short reveal latency, and an assumption that a majority of Keypers behave honestly.
