Abstract
Alerts play a vital role in conveying information about events, promptly responding to them can prevent disastrous consequences. Many alerting apps face issues with centralized servers, leading to vulnerabilities. Users also encounter problems like anonymous profiles and falsified alerts that undermine trust. Hence, Transforming Alert Management Systems is imperative due to their challenges. In pursuing improved technologies, the adoption of Blockchain emerged as a solution to address these issues. Blockchain’s characteristics, including enhanced security, unmodifiable data records, and eliminating central authority, make it ideal for creating a Decentralized Alerting Application (Dapp). Moreover, delays in emergency services reaching the location can pose serious issues that can be effectively addressed by leveraging community first responders living close to the incident site. The primary focus of this study is leveraging these features to create a Dapp that provides tamperproof alerts, combating fake alerts. While businesses migrating to Blockchain are concerned about transaction time impacting user migration, Sharding, a cost-effective Layer 1 Blockchain Scalability solution, is proposed as an efficient solution. This research explores how Sharding can enhance Blockchain-based Alert systems by reducing costs and time and improving security.
