Company directives

Exchanging sensitive documentation or merely digital assets should be as easy as exchanging information. Blockchain technology proposes the ideal foundation to make this a reality. To address this issue we have developed safe, fast and inexpensive blockchain based solution, a future way of sensitive document exchange and eDelivery. Our technology was created so it could replace the traditional distribution services and actively reduce costs. We are building Individual Digital Identities by verifying wallet accounts through sensitive document exchange and KYC. With the creation of self-sovereign identities, we are able to simplify the identification process as it will be based on measurable data and proven facts. To go even further, FOURdx can reduce the usage of paper and actively help the environment. The applications of our protocols are limitless, as they could be applied to any industry.

What makes us unique?

The 4THPILLAR products combine several advanced technologies and deliver first blockchain based EU compliant solutions. What makes us unique is the way our infrastructure is conceptualized, developed and integrated into the business. Our products are blockchain based and combine several digital solutions that solve many well-known document exchange and identity challenges. The 4THPILLAR solutions have great possibilities for the future and the potential to expand. Our infrastructure combines functions and functionality that are not offered by anyone in the market today and can be easily applied to any industry.

Legislation Impact

In this time, companies are already using different systems for exchanging and storing sensitive personal electronic documentation within the company as well as between the company and individuals. Most of the digital activities and document exchanges run through emails, which is not a safe and EU compliant way of eDelivery. The solutions offered by the 4THTECH solve just that. Our platform provides secure, fast, EU compliant and technically refined solutions.
