Scaling Nakamoto Consensus to Thousands of Transactions per Second

Understand

This paper presents Conflux, a fast, scalable and decentralized blockchain system that optimistically process concurrent blocks without discarding any as forks.

• The Conflux consensus protocol represents relationships between blocks as a direct acyclic graph and achieves consensus on a total order of the blocks.
• Conflux then, from the block order, deterministically derives a transaction total order as the blockchain ledger.
• We evaluated Conflux on Amazon EC2 clusters with up to 20k full nodes.
