Media Technology Digital Publishing Blockchain Platform for Journalist Verification

The Story

The client partnered with FiftyFive to develop a blockchain-based MVP that verifies journalists through digital passport scanning and authenticates articles using immutable smart contracts. The goal was to create a secure, scalable, cross-platform system that improves trust in digital publishing. FiftyFive provided end-to-end engineering across blockchain, mobile, backend, integrations, and cloud to deliver the complete MVP.

The client is a media-technology company building a blockchain-powered digital publishing platform that verifies journalist identities, authenticates articles, and enables secure, transparent, gas-free transactions across mobile and web applications.
