The meteoric rise of Decentralized Finance (DeFi) has been accompanied by aplethora of frequent and often financially devastating attacks on its protocolsThere have been over 70 exploits of DeFi protocols, with the total of lostfunds amounting to approximately 1.5bn USD. In this paper, we introduce a newapproach to minimizing the frequency and severity of such attacks: dissimilarredundancy for smart contracts. In a nutshell, the idea is to implement aprogram logic more than once, ideally using different programming languages.Then, for each implementation, the results should match before allowing thestate of the blockchain to change. This is inspired by and has clear parallelsto the field of avionics, where on account of the safety-critical environment,flight control systems typically feature multiple redundant implementations. Weargue that the high financial stakes in DeFi protocols merit a conceptuallysimilar approach, and we provide a novel algorithm for implementing dissimilarredundancy for smart contracts.
