Abstract

Avalanche offers developers flexibility through subnets and EVM-compatible smart contracts. However, the platform's deterministic block execution limits the use of traditional random number generators within these contracts.

To address this, a mechanism is proposed to generate verifiable, non-cryptographic random number seeds on the Avalanche platform. This method ensures uniformity while allowing developers to build more versatile applications.
