Decentralised Random Number Generation

TL;DR

This paper introduces a new encrypted share threshold scheme to prevent the Last Actor Problem in decentralised random number generation, enhancing security by ensuring no single participant can manipulate the outcome.

Contribution

The paper presents a novel encrypted share threshold scheme that mitigates the Last Actor Problem in decentralised random number generation.

Findings

The scheme effectively prevents manipulation by the last revealing participant.

It enhances security in decentralised systems.

The approach is practical for real-world deployment.

Abstract

Decentralised random number generation algorithms suffer from the Last Actor Problem, in which the last participant to reveal their share can manipulate the generated random value by withholding their share. This paper proposes an encrypted share threshold scheme which prevents this attack.
