Blockchain-based Smart Contracts: A Systematic Mapping Study [PDF]
Fourth International Conference on Computer Science and
Information Technology (CSIT-2017), 2017 An appealing feature of blockchain technology is smart contracts. A smart contract is executable code that runs on top of the blockchain to facilitate, execute and enforce an agreement between untrusted parties without the involvement of a trusted third party. In this paper, we conduct a systematic mapping study to collect all research that is relevant

Smart Contract Broker: Improving Smart Contract Reusability in a Blockchain Environment [PDF]
Sensors, 2023 In this paper, we propose a smart contract broker to improve the reusability of smart contracts in a blockchain environment. The current blockchain platform lacks a standard approach to sharing and managing smart contracts, which makes it difficult for ...

DEFECTCHECKER: Automated Smart Contract Defect Detection by Analyzing EVM Bytecode [PDF]
IEEE Transactions on Software Engineering, 2020 Smart contracts are Turing-complete programs running on the blockchain. They are immutable and cannot be modified, even when bugs are detected. Therefore, ensuring smart contracts are bug-free and well-designed before deploying them to the blockchain is extremely important. A contract defect is an error, flaw or fault in a smart contract that causes it

Smart Contract Upgradeability on the Ethereum Blockchain Platform: An Exploratory Study [PDF]
arXiv, 2023 Context: Smart contracts are computerized self-executing contracts that contain clauses, which are enforced once certain conditions are met. Smart contracts are immutable by design and cannot be modified once deployed, which ensures trustlessness. Despite smart contracts' immutability benefits, upgrading contract code is still necessary for bug fixes ...
