New post on ! Unpredictable RANDAO By: - banr1 - banri - vita - Hiro 🔗 Highlights: - The traditional RANDAO mechanism in Ethereum is vulnerable to attacks that allow manipulators to predict future randomness, leading to unfair advantages. - The proposed Unpredictable RANDAO reduces the number of possible future states an attacker can control from an exponential scale (2^k) to a linear scale (k+1), even if they control k consecutive slots. - By using a committee-based Distributed Key Generation (DKG) and threshold signatures, the new method makes it significantly harder for attackers to predict future randomness. - The economic incentives for attacks like Selfish Mixing and Forking are weakened, as the predictability of the randomness is drastically reduced. - Future research is needed to quantitatively assess the impact of this new approach on real-world economic incentives and the liveness of the blockchain. ELI5: This research discusses a new way to generate randomness in Ethereum's Beacon Chain that makes it much harder for attackers to predict or manipulate future outcomes. Instead of relying on one person to create the random number, a group of people work together to make it, which makes it safer.
