A New Proof-of-Stake Sharding Architecture for Public Blockchains

This paper proposes a sharding architecture solution for public blockchains aiming for significantly improving the transaction processing performance. The solution uses the Proof-of-Stake Voting (PoSV) consensus protocol proposed by Tomochain for intra-shard consensus because PoSV provides 2 second...
