## About Authentic.network

VC Fund · Chemnitz, Germany

Authentic.network is a blockchain startup that helps brands and businesses with authentic secure encrypted code. The company's proprietary cryptographic printing process converts standard printers into security printers. The blockchain connects an unbreakable physical code with an ambiguous digital twin and completely secures it. A KIidentifies usage patterns, analyzes them, and detects attacks early on in order to eliminate them independently. The possibility of contaminated codes is thus eliminated. The combination makes counterfeit detection and prevention easier and more secure than ever before.
