I have a computer constantly connected to the network with free electricity. Of course, I could mine, but I have outdated hardware + I don't like the idea of meaningless calculations.
I want, without investing my own funds, to support the ecosystem of any coin and receive currency for it. For example, my computer can contain the entire blockchain, verifying the history and current operations, saving the network from an attack of 51%.
Please, tell me about similar coins.
Why don't you participate in Quarkchain Test-net 2.0 mining campaign, Quarkchain adopts 3 different type of mining algorithm as follows
