Reliable Smart Contracts

Abstract

The rise of smart contracts executed on blockchain and other distributed ledger technologies enabled trustless yet decentralised computation. Various applications take advantage of this computational model, including enforced financial contracts, self-sovereign identity and voting. But smart contracts are nothing but software running on a blockchain, with risks of malfunction due to bugs in the code. Compared to traditional systems, there is an additional risk in that erroneous computation or transactions triggered by a smart contract cannot be easily rolled back due to the immutability of the underlying execution model. This ISoLA track brings together a number of experts in the field of smart contract reliability and verification to discuss the state-of-the-art in smart contract dependability and discuss research challenges and future directions.
