Opius: Email Reputation Platform

Purpose and goal

Opius is a new platform for email, which uses reputation scores to eliminate inbox overload and email fraud. Blockchain technology is used to gather reputation scores in a secure, transparent way, without sharing any private data. Opius will be free for users, and companies will pay to manage their reputation. It will work with any of the 6 billion existing email addresses, and will be accessible via Opius apps or any modern email provider.

Expected results and effects

This project produced a fully functioning prototype of the Opius email reputation system, which achieved the desired security, privacy, and inbox efficiency. User testing and data analysis confirms that inbox overload and email abuse are both reduced by using a reputation-based email network. This prototype has allowed the Opius team to file a patent application and pursue further funding.

Planned approach and implementation

Opius uses blockchain technology to gather reputation data from all users, without sharing any private data. By doing this, the Opius inbox can rank emails based on the user´s relationship to the sender, and the sender´s credibility in general. All data is encrypted at all times, and all users can verify how their reputation was created at any time, using the blockhain. This method makes a normal email inbox 55% more efficient on average (99% in some cases), and will eliminate the incentives for email fraud, a $3 trillion industry as it scales.
