About Guardtime

Who we are

The world's largest blockchain company by revenue, headcount and actual customer deployments. A team of over 130 cryptographers,  developers and security architects, with decades of experience defending networks from nation-state attack.  We underpin an entire government and our customers include the largest global defense and telecom vendors. 


What we do

 Our key insight is that the most valuable application of blockchain is for supply chains - software, physical and information supply chains that are within and across organizations.  We work with clients to understand those supply chains and build solutions to harden them, eliminating inefficiencies and providing mathematical certainty for their integrity  - track and trace at the digital and physical item level.


Our Philosophy 

The Guardtime stack is the Unix philosophy applied to blockchain - abstraction and encapsulation  into layers , each of which does one function well. This approach provides scalability, interoperability, reliability and works with legacy systems.  Crypto-currency protocols are great for what they were designed for - not for large scale enterprise data supply chains.


Our Mission

Google's mission to organize the word's information and make it universally available. Our mission is to validate that information and make it universally reliable.
