Blackcoin is 4 yrs. old as of yesterday with continuous and current ongoing development and a thriving community. There is no mining and no miners to support or to use their power to extort the devs and community with. Blackcoin uses its "proof-of-stake" (PoS) operation to protect its blockchain in place of the miners. By maintaining an open wallet on your running computer the user is rewarded with staking coins. The more Blackcoin you have in your wallet the more frequently you will receive a stake reward. With its age, PoS operation, and its active community Blackcoin has a lot to offer and well worth investigating. We have a lot going on.
