A New Hybrid Consensus Protocol: Deterministic Proof Of Work
The Decentralized-Consistent-Scale (DCS) Triangle defines three dimensions
that illustrate the tradeoffs of the blockchain consensus mechanism. In this
paper, we propose a new hybrid consensus protocol, called Deterministic Proof
of Work (DPoW), which can reach high levels of scalability and consistency
without significant reduction to decentralization. Our protocol introduces a
Map-reduce PoW mining algorithm to perform alongside Practical Byzantine Fault
Tolerance (PBFT) verification, which together allow for transactions to be
confirmed immediately, largely improving scalability. In addition, the protocol
is designed such that forking cannot occur, ensuring strong consistency and
security against a multitude of attacks. The Map-reduce PoW mining process
ensures that no single entity can control the network, guaranteeing
decentralization. We analyzed the security of our protocol by evaluating the
possibility of double spending attacks, and furthermore, conducted experiments
which demonstrate our claims.Comment: 6 figure
