A performance-oriented Proof-of-Stake consensus called Supernode Proof-of-Stake Consensus with the features of constant interval block minting, cold minting and stake liquidity has been designed for the V SYSTEMS blockchain platform. We also describe the lineage and differences to the original Proof-of-Stake Consensus introduced by Peercoin in 2012.
The Supernode Proof-of-Stake Consensus is an evolution toward high performance blockchain systems. The ecosystem resource can be directed more effectively toward hardware upgrade of supernode, and the system response is not only fast but also much more predictable and stable. We also designed Minting Average Balance to support stake liquidity
