A Blockchain-Based Solution to High-Volume Web Scraping With Smart Contracts on Ethereum

Sammanfattning: Since it is dicult to protect servers from high-volume scraping, a new wayto reduce excessive requests is needed. Using rougher methods such as ratelimit or IP control mechanisms are not sucient. In this report we propose anew solution to counter high-volume web scraping with blockchain technology.We create a cryptographic algorithm and use it on a mobile device tocommunicate with an Ethereum network with the purpose to control serveraccess. Our studies seem to indicate that blockchain technology on mobiledevices has potential to limit the way information is accessed. Furthermore,blockchains have potential to act as an additional security layer rather thansimply a network solution. To determine the practical eectiveness of thissolution, more studies are needed.
