Project Description
OpenTrust is a blockchain powered mobile application designed to combat phone scams and protect digital assets by verifying caller identities in real time. It’s built with a strong focus on safeguarding vulnerable populations, especially the elderly who are often targeted by fraudulent calls.
The platform uses decentralized identity verification backed by blockchain to ensure trust, transparency, and data integrity in digital communications. Blockchain’s immutable and tamper-proof ledger guarantees that caller identity data is securely stored and verifiable. This empowers users to confidently assess incoming calls, regardless of their location or country of residence.
By removing the need for centralized authorities, OpenTrust reduces the risk of fraud and enhances online safety through a trustless, decentralized infrastructure. The system also supports transparent governance and secure data sharing, making it a scalable solution for modern cybersecurity challenges.
For demonstration purposes, OpenTrust is developed using Hardhat, a local Ethereum development environment that simulates blockchain interactions.
Data Story
John, a 72 year old retiree living in USA received a phone call one afternoon from someone claiming to be from his bank. The caller sounded urgent, warning John that his account had been compromised and requesting his personal details to "secure" it immediately.
In the past, John might have panicked and complied. But this time, he had OpenTrust installed on his phone.
As the call came in, the OpenTrust widget activated and scanned the caller’s identity against its blockchain-powered verification network. No verification badge appeared indicating the caller was not registered with any trusted institution on the blockchain.
Thanks to this real-time alert, John refused to share any personal information, ending the call safely.
The blockchain technology is powered by phone number directories of trusted governments and banks. Thanks for their data, it can be accessed transparently, and decentralised across the globe
