Interactive Proof-of-stake
This addresses security issues in decentralized cryptocurrency protocols for users and developers, but appears incremental as it builds on existing Proof-of-stake methods.
The paper tackles security problems in popular Proof-of-stake consensus protocols by proposing Interactive Proof-of-stake, which reduces variables for miners and incorporates communication into block generation, showing it is more secure than current pure Proof-of-stake protocols.
The paper examines decentralized cryptocurrency protocols that are based on the use of internal tokens as identity tools. An analysis of security problems with popular Proof-of-stake consensus protocols is provided. A new protocol, Interactive Proof-of-stake, is proposed. The main ideas of the protocol are to reduce a number of variables a miner can iterate over to a minimum and also to bring a communication into block generation. The protocol is checked against known attacks. It is shown that Interactive Proof-of-stake is more secure than current pure Proof-of-stake protocols.
