Network Intrusion Management of Web Form Spamming using Blockchain

Web form spamming is a growing cybersecurity threat that disrupts digital services and compromises data integrity. Traditional defenses like CAPTCHA are increasingly ineffective against sophisticated bots. This study proposes a blockchain-based framework for managing network intrusion caused by web form spam. By leveraging smart contracts and micro-incentivization through token deposits, the system validates legitimate submissions and discourages malicious activity. A comparative experiment between CAPTCHA-only and blockchain-enabled systems demonstrates significant improvement in spam detection accuracy and user experience, with minor latency trade-offs. The results highlight blockchain’s potential as a secure, transparent, and decentralized solution for web form spam prevention.
