Blockchain Document Certification


Here at Signature Chain (SIGN), we're experienced in building centralized applications used in Sustainable Development Project Platforms for emerging countries and have committed to other various projects in dealing with large quantities of files and certification steps.

We've studied and identified what could facilitate and accelerate the certification process for many enterprise areas using blockchain technology, which offers the best guarantees regarding security, autonomy, and execution time.
