Kcoin blockchain is committed to being a blockchain platform that integrates smart contracts, PoC hard drive mining, and supports decentralized encrypted payments. In the early stage, Kcoin mainly focused on PoC hard disk mining, which involved mining through a consensus mechanism based on (hard disk) capacity proof. The threshold for miners to participate was extremely low, electricity consumption was low, and it was safer and more reliable; At the same time, Kcoin supports smart contracts and can issue PoC tokens on the Kcoin network to achieve decentralized applications and promote the improvement of the Kcoin platform ecosystem; In the future, Kcoin will add zero-knowledge proof technology, strengthen the security and decentralized characteristics of the entire ecology, and build Kcoin into a decentralized cryptocurrency....
