Guardtime, Europe’s leading deep tech company, was founded in Tallinn, Estonia in 2007 by a team of cryptographers and computer scientists. The initial goal was to support the Estonian Government to design and build a system that would allow information to be validated without centralized trust authorities. The invention, KSI replaces trust with digital truth - formally verifiable mathematical proof of the integrity of data, networks, systems and processes, without the reliance on keys, secrets or centralized trust authorities. KSI technology enables applications to be built with truth inherent in their design, delivering value wherever there is digital.
