About the Guardtime KSI

Guardtime Keyless Signature Infrastructure (KSI) is a blockchain-based data integrity platform. It provides a way to verify the authenticity and integrity of digital data without the need for private cryptographic keys. KSI uses a mathematical technique called hash-chaining to create a unique, tamper-proof "signature" for any digital asset. This signature can be verified independently of Guardtime, ensuring long-term data integrity and providing a strong defense against data manipulation and cyberattacks. It is used by governments and enterprises to secure critical data.
