Spacemesh

Spacemesh is a decentralized, layer-one blockchain protocol built around a novel proof-of-space-time consensus mechanism, designed to bring cryptocurrency to the masses by using idle computer storage that ordinary people already own rather than energy-intensive mining hardware. Its mission is to create a permissionless, decentralized network resistant to centralization pitfalls common in earlier blockchains. The protocol's official client implementation, go-spacemesh, powers the race-free consensus computer, and network participants earn the native SMH cryptocurrency for contributing unused storage.
