This project aims to build a miniaml on-chain random beacon on Ethereum. The core algorithm we apply to generate a random number is Pietrzak Verifiable Delay Fuction (VDF) [original paper]. The related machanisms are described in our Medium articles series [1, 2, 3]. The overall development comprises of two parts; VDF verifier and VDF prover. VDF evaluation and the following verification are carried out off-chain. We’re developing it using Python and Golang. VDF verification is carried out on Ethereum smart contracts. We’re developing it using Solidity and Yul.
