BlockTac’s innovations are characterised by applying Blockchain technology and Machine Learning to business problems. The uniqueness of our digital certificates and seals has led us to define new markets and lead the way in opening them up. What they have in common is protection against fraud: for food and consumer products, for access to healthcare services and medical records (including facial recognition), for online voting processes, and for the data transmitted by sensors and machines on Internet of Things platforms in precision agriculture and Industry 4.0.
