A taxonomy of blockchain consensus protocols: A survey and classification framework

作者：

Highlights：

• Blockchain refers to the digital public ledger used in a distributed network.

• Peers in a blockchain have to reach a consensus on the state of the transactions.

• The seminal consensus protocols (Proof-of-Work and Proof-of-Stake) face a number of limitations.

• Many consensus protocols have been proposed to mitigate these limitations.

• A classification framework can help the analysis and development of existing and new consensus protocols.
