A peer-to-peer crypto-currency design derived from Bitcoin where Proof-of-Stake replaces Proof-of-Work to provide most of the network security. Under this hybrid design proof-of work mainly provides initial minting and is largely non-essential in the long run. The energy consumption doesn’t affect the security and integrity of the chain thus providing a clean and efficient system . Proof-of-Stake is based on coin age and generated by each node via a hashing scheme similar to Bitcoin but on a smaller search space . The integrity of the blockchain history and transactions is guaranteed by a broadcasted checkpoint mechanism .
