Sugarchain is a decentralized, peer-to-peer (P2P) digital currency and payment network supported by an open-source blockchain protocol, launched by Zenny Kim and Volodymyr Biloshytskyi.

Sugarchain claims to be the world's fastest PoW blockchain, that has the first Native SegWit (Bech32) built-in by default. Unlike Bitcoin, Sugarchain has no rounding errors when the block reward is halved. It launched fairly and follows Nakamoto's one-CPU-one-vote.

Through Sugarchain, users can make payments to anyone in the world at the highest speeds in 5 seconds, and the lowest costs compared to other digital assets. Compared to bitcoin, it is 120 times faster; Litecoin, it is 30 times faster; and Dogecoin, it is 12 times faster.
