Case Study

The Challenge

Build a decentralized, trustless file transfer system that provides end-to-end encryption without relying on centralized servers, using Hedera Hashgraph for immutable transfer records.

My Approach

Implemented a DRAFT protocol for chunked file transfer with RSA + AES hybrid encryption. Each transfer is recorded on Hedera with manifest-based metadata tracking, ensuring provenance and integrity.

The Results

Created a fully decentralized file transfer system with military-grade encryption. The DRAFT protocol enables efficient large file handling while Hedera provides tamper-proof transfer records.
