On the Practicality of a Smart Contract PKI [PDF]
2019 IEEE International Conference on Decentralized Applications and Infrastructures (DAPPCON), 2019 Public key infrastructures (PKIs) are one of the main building blocks for securing communications over the Internet. Currently, PKIs are under the control of centralized authorities, which is problematic as evidenced by numerous incidents where they have been compromised.

Aroc: An Automatic Repair Framework for On-Chain Smart Contracts
IEEE Transactions on Software Engineering, 2022 Ongoing smart contract attack events have seriously impeded the practical application of blockchain. Although lots of researches have been conducted, they mostly focus on off-chain vulnerability detection. However, smart contracts cannot be modified once

Verification of smart contracts: A survey
Pervasive and Mobile Computing, 2020 Abstract To achieve trust and continuity in the smart contracts-based business process execution, the verification of such smart contracts is mandatory. A blockchain-based smart contract should work as intended before using it. Due to the immutable nature of blockchain, any bugs or errors will become permanent once published and could lead to huge ...

Advanced Functional Materials, EarlyView.This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

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 ...
