SAILFISH System to Find State-Inconsistency Bugs in Smart Contracts

A group of academics from the University of California, Santa Barbara, has demonstrated what it calls a “scalable technique” to vet smart contracts and mitigate state-inconsistency bugs, discovering 47 zero-day vulnerabilities on the Ethereum blockchain in the process. Smart contracts areprogramsstored on the blockchain that are automatically executed when predetermined conditions are met
