A distributed randomness beacon is a system that generates unpredictable and publicly verifiable random numbers using a network of independent participants. This cryptographic primitive ensures that no single entity can manipulate the random output. The randomness produced is accessible and verifiable by anyone.
Context
Distributed randomness beacons are essential for numerous decentralized applications requiring fair and unbiased random inputs, such as lotteries, leader election in Proof of Stake protocols, and gaming. The security of such systems relies on the collective action of many parties to prevent malicious actors from influencing the outcome. Developments aim to enhance the robustness and unbiasability of these randomness sources.
Research demonstrates a scalable distributed randomness beacon by enforcing verifiable inclusion of all entropy contributions using insertion-secure accumulators.
