Blockchain-based system for secure outsourcing of bilinear pairings

•We analyze the limitations in existing SOBP-based schemes, such as the one-malicious model (Strong Assumption), a secure channel (Insufficiency), and a trusted server (Centralization).•We propose a novel blockchain-based system for SOBP based on a permissioned version (i.e. a blockchain ledger maintained by some permissioned nodes), to efficiently address the limitations.•We prove our proposed approach in a one trusted program model and implement it on Ethereum (an open-source blockchain system) to show its utility.
