【Abstract】There are many papers and tools regarding the detection of unsafe contracts, but few ways for detection results to practically benefit contract users and owners. This paper presents a Blockchain Safe Browsing (BSB) platform to safely disseminate those detection results. An encrypted blacklist will be generated to provide privacy preserving user warning before they make transactions with unsafe contracts. Contract owners will be notified that there are vulnerabilities in their contracts, and they can purchase related reports which record how to exploit the vulnerabilities. The profits inspire the researchers to contribute their update-to-date lists of unsafe contracts. An effective encryption scheme is developed to guarantee that only contract owners can decrypt the encrypted reports. Extensive evaluations demonstrate that our prototype can function as intended without sacrificing user experience. (c) 2023 ISA. Published by Elsevier Ltd. All rights reserved.
