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

Declarative Smart Contracts [PDF]
arXiv, 2022 This paper presents DeCon, a declarative programming language for implementing smart contracts and specifying contract-level properties. Driven by the observation that smart contract operations and contract-level properties can be naturally expressed as relational constraints, DeCon models each smart contract as a set of relational tables that store ...

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 ...

DEFECTCHECKER: Automated Smart Contract Defect Detection by Analyzing EVM Bytecode [PDF]
, 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

Probabilistic Framework For Loss Distribution Of Smart Contract Risk [PDF]
arXiv, 2021 Smart contract risk can be defined as a financial risk of loss due to cyber attacks on or contagious failures of smart contracts. Its quantification is of paramount importance to technology platform providers as well as companies and individuals when considering the deployment of this new technology. That is why, as our primary contribution, we propose

Blockchain Enabled Smart Contract Based Applications: Deficiencies with the Software Development Life Cycle Models [PDF]
Baltica Journal, Vol. 33, Issue 1, 20th January 2020, ISSN:
0067-3064, pp. 101-116, Available:
http://www.balticajournal.com/baltica/index.php/jTracker/index/IL1qQ, 2020 With the recent popularity of Blockchain and other Distributed Ledger Technologies (DLT), blockchain enabled smart contract applications has attracted increased research focus. However, the immutability of the blocks, where the smart contracts are stored, causes conflicts with the traditional Software Development Life Cycle (SDLC) models usually ...

An Empirical Study of Protocols in Smart Contracts [PDF]
arXiv, 2021 Smart contracts are programs that are executed on a blockhain. They have been used for applications in voting, decentralized finance, and supply chain management. However, vulnerabilities in smart contracts have been abused by hackers, leading to financial losses. Understanding state machine protocols in smart contracts has been identified as important

Abusing the Ethereum Smart Contract Verification Services for Fun and Profit [PDF]
arXiv, 2023 Smart contracts play a vital role in the Ethereum ecosystem. Due to the prevalence of kinds of security issues in smart contracts, the smart contract verification is urgently needed, which is the process of matching a smart contract's source code to its on-chain bytecode for gaining mutual trust between smart contract developers and users.
