At the World Economic Forum, blockchain was recognized as one of six global trends that will hugely impact society in the next decade.


To save money through control

Blockchain is the most reliable technology available today. Safety is among the crucial criteria when it comes to business. Due to the increase of hacker attacks, it is cheaper to invest in blockchain technology today than deal with the financial consequences of a possible data leak.

To keep data immutability

Decentralized data and complicated automated encryption provide reliability and ensure that if one block breaks, your data remains still. It is essential for NFT marketplaces, art auctions, music distributed companies and other IP-related spheres.

To stay anonymous and save

Joint real estate ownership, trading, or making cross-border payments in complete anonymity is another bonus of blockchain technology. Moreover, non-disclosure of personal data is one of the vital issues for medical centers. Secure sharing of medical data allows patients to ensure the fundamental right of keeping any information about their disease private.

To monitor quality and provide transparency

Blockchain technology allows seeing the logistic way of goods in real-time, retention schedule, delivery information, and reduces the number of counterfeits. One of the world’s best software makers, IBM, has already implemented such enterprise blockchain systems for the USA to improve food safety.

To reduce human factor and accelerate processes

Blockchain not only allows to remove intermediaries from the financial transactions but also speeds up all processes. Due to the real-time technology, IoT operating systems have already been working in state security and civil aviation. In general, blockchain allows synchronization of many processes and platforms. It leaves easy decisions to the machine, making your customers and stuff life more manageable and saving your finances.

To decrease the level of bureaucracy

Signing contracts, making financial transactions, issuing diplomas and passports, and even conducting a voting procedure – all this can be done online and 100% secure with the help of blockchain technology. Thanks to decentralized data storage, actions are speeded up, so you don’t have to wait and undergo a lengthy authorization procedure.

Will von Behr

Founder @ Urbs Travel

““I got an amazing product that was exactly what I envisioned when I first sat out & drew the plans. The two areas that I think where Stan & his team particularly excel: first is attention to detail (…) & secondly the kind of support they’ve provided after the app was largely complete. I’m sure the number of teams just do the bug work & leave it but they are [Interexy team] always on hand to answer any questions really at any time of day which is incredible.

So I’d encourage anyone who wants to build any sort of product to use Stan & his team. It’ll accelerate your business and make your life a whole lot easier.””
