UTStamp system is an open blockchain system that reliably keeps and tracks digital assets at low cost. It produces a unique digital mark for each digital asset (document, picture, digital currency, among others) that can be verified with the combination of Bitcoin’s blockchain and UTStamp blockchain for the following attributes:

• Proof of the time when a document is registered to the UTStamp chain
• Proof of the contents of the document
• Absolute time stamp – For every one minute, UTStamp will generate a universally unique digital signature + QR code for the corresponding time point so that the time signature is not predictable until the time is present.
• The digital mark generated by the UTStamp system cannot be altered once it is created and it can be mathematically verified by any 3rd party with Bitcoin’s blockchain and the UTStamp chain based on the UTStamp published algorithm.
• UTStamp works across public cloud platforms and public blockchain systems.
• UTStamp is now running on multiple cloud platforms, Amazon AWS, Microsoft Azure and Ali Yun, and it can be deployed on any private cloud system while seamlessly integrating with UTStamp public chain system.
• Today, the UTStamp chain is integrated with Bitcoin and Ethereum.

The UTStamp system is very scalable and cost efficient and can stamp very large volume (billions per second) of digital assets with Bitcoin’s blockchain backed digital mark. UTStamp also provides public API and SDK for 3rd party integration.
