- toastal 7y agoWasn't there also like CureCoin that unfolds proteins for medical application?
- haakon 7y agoYes, and there's also SolarCoin which rewards users for producing renewable energy. The problem is that these coins are centralised, so while they may be very useful for what they do, they don't solve the same problem as proof-of-work coins which aim to be decentralised.
- untoreh 7y agothere is also gridcoin but they are not useful pow. they are proof of stake where the stake is the amount of contribution towards boinc projects and the likes, and they are affected by the oracle problem
- swinglock 7y agoIs that useful for anything other than the Primecoin?
- tylersmith 7y ago"Useful PoW" is a dead end. Good PoW functions require properties that rule out real world useful problems.
