Shared Data Problems

It’s all about the data – metadata. Sharing data about data or finding sources of truth is an information assurance problem common to many industries.  Jitsuin solved one of the hardest data collaboration problems – cybersecurity of Connected Things – and in doing so solves equally complex or simple data sharing problems for any critical assets.

Founding Vision

The bright future of Digital Transformation with Connected Things needs to run on truthful data. Keeping Things secure to produce reliable data is a team sport best played on Blockchain. Our founding vision is to align all in the cybersecurity supply chain to move fast and fix Things so assured data can drive intelligent decisions.


Jitsuin is a Japanese word. Ask a Japanese citizen to sign a document and they’ll pick up one of their three ink chop seals, not a pen. If the document is official, they’ll use their most trusted stamp: the jitsuin. 

Jitsuins are individually hand-carved by master craftsmen with bespoke designs on hard material that last a lifetime. Each unique jitsuin is registered by its owner at their local municipal office. If a contract is disputed, the ink seals can be checked against records. 

Analogous to the heritage Japanese system of trust, Jitsuin records the provenance of Things and provides access to these permanent records. 

Jitsu means truth or essence; to us Jitsuin means:

 Truth in Things
