Predicting Random Numbers in Ethereum Smart Contracts

The Ethereum blockchain is deterministic and as such it imposes certain difficulties for those who have chosen to write their own pseudo-random number generator (PRNG), which is an inherent part of any gambling application. We decided to research smart contracts in order to assess the security of PRNGs written in Solidity and to highlight common design antipatterns that lead to vulnerabilities allowing prediction of the future state.
