Smart Contracts

2020
When Nick Szabo pioneered the idea of a smart contract in the 1990s, the economic and communications infrastructure available at that time could not and did not support the protocols needed to execute and apply smart contracts. While smart contracts may be viewed as an example of the use of blockchain and blockchain technology which offers great ...

SMARTIAN: Enhancing Smart Contract Fuzzing with Static and Dynamic Data-Flow Analyses

International Conference on Automated Software Engineering, 2021
Unlike traditional software, smart contracts have the unique organization in which a sequence of transactions shares persistent states. Unfortunately, such a characteristic makes it difficult for existing fuzzers to find out critical transaction ...
