The Hydra Framework for Principled, Automated Bug Bounties

Lorenz Breidenbach*, Phil Daian*, Florian Tramèr* and Ari Juels   (*joint first authors)

IEEE Security & Privacy 2019


We present the Hydra Framework, a new principled approach to modeling and detecting security-critical bugs. By fusing a variant of classical N-version (redundant) programming with automated bug-bounty payouts, the Hydra framework is particularly appealing as a way to provide economically rigorous and cost-effective bounty protections for smart contracts.
