There's too many coins to name lol.
Proof of work = generating blocks through gpu/asic hashing
Proof of stake= generating blocks through staking coins on the network
i can't understand what is the point of the question ( proof of stake vs proof work) correct me if i'm wrong in the bounty campaign or signature campaign the payment of the campaign made from the stake, working in the campaign thats the proof of work to get stake as payment.
