Right to Sign: Safeguarding data immutability in blockchain systems with cryptographic signatures over a broad range of available consensus finding scenarios
This addresses the problem of insufficient tamper resistance in blockchain consensus methods for users and developers, but it is incremental as it builds on existing methods rather than proposing a new paradigm.
The paper tackles the lack of a consensus method that uniformly addresses throughput, scalability, tamper resistance, and consistency in blockchain systems by introducing Right to Sign, which adds cryptographic signatures to various consensus methods to enhance tamper resistance.
The choice of the consensus method ultimately determines throughput, scalability, tamper resistance, and consistency of a blockchain system. However, across all the types of blockchain (private, semi-private, consortium, or public), there is no consensus method that uniformly addresses all these traits. Verifiable lottery algorithms (Proof of ...) increase tamper resistance but show weakness in throughput and scalability, while established methods like PAXOS and RAFT provide no additional protection against tampering. In this paper, we introduce Right to Sign which aims to provide additional tamper resistance by cryptographic signatures over a broad range of available consensus finding methods.
