Matadepera, Spain

Teaser of the company

BlockTac is a factory of trust: BlockTac fights fake consumer products and data with our certificates and single-use digital seals registered with Blockchain technology, designed for brand protection and consumer engagement. And with our Blockchain-of-things devices, that communicate directly with IoT sensors, encrypt the data, and store it in a public Blockchain. The information now becomes trusted and traceable, impossible to change, truly linked to its source.

BlockTac will test and validate the following blockchain-based solution in the scope of BlockStart:

Blockchain of Things Devices to secure and authenticate datasets from IoT platforms 

Data exchanged on IoT devices and in Industry 4.0 is frequently targeted by hackers. One-third of AI projects provide ineffective or dangerous results due to the manipulation of their data. This affects many industries: Automotive, Healthcare, Industry 4.0, Smart Cities, etc. Fraud in these datasets endangers human lives, compromises democracy, damages business assets, and degrades the environment.

We have produced a family of autonomous hardware devices that collect information directly from IoT sensors or machines, encrypt the data, and store it in a public Blockchain. The information now becomes trusted and traceable, impossible to change, truly linked to its source. We name these edge computers “Blockchain-of-Things” devices.

They make impossible for third parties to amend or impersonate the real producers of the data, therefore protecting the training of AI systems, and reducing energy consumption. Companies will be fully accountable for the information they produce, use, or sell. Privacy is fully protected, and potential scammer immediately identified. Our strategy is unique for the low cost of our devices and the minimal cost of storing the data. Ours is the sole solution fully securing information against hacking, identifying its origin and ownership, and making it safe and tradable.
