Article Introduction — Blockchain technology proposes the ideal foundation to simplify digital value-holding file and documents exchange. To address this issue in 2017, 4thpillar technologies (i.e. 4thtech), proposed and later developed a safe, fast cross DLT blockchain-based solution, which leverages trust provided by the blockchain and provides secure, immutable, instant cross-border electronic data and document exchange (i.e. FOURdx). To provide an option for blockchain address ownership verification, the identification mechanism (i.e. FOURid) later was constructed in 2018, which can authenticate verified connection between a blockchain wallet and a person. Notarisation Service (i.e. FOURns) is also an essential part of the 4thtech ecosystem and provides unique digital data or document timestamp and authenticity verification. Our products are reducing the usage of paper and actively help the environment. The applications of our services are limitless, as they could be applied to any industry.

The story behind the 4thpillar brand

4thpillar technologies or short 4thtech is a European consortium of companies and people, that work together to develop a framework for development and implementation of Blockchain services and infrastructure, which will be compatible and in line with European Blockchain services infrastructure and usable or extendable globally. According to many, there are three fundamental technology developments in human history; (1) the invention of electricity; (2) the invention of the microprocessor, and; (3) the invention of the internet. We are certain, that the invention of blockchain technology is the fourth fundamental technology pillar, which revolutionary applications will yet to be revealed to the world.

The innovation

The innovation and ingenuity reveal from the fact, that the blockchain eDelivery protocol does not store the transmitted electronic data and documents on the blockchain. The electronic data and documents are stored off-chain. The protocol records links to encrypted files and hashes of the encrypted content on the blockchain. This safeguards the rights of individuals to confidentiality and privacy. Designed and built completely by the 4thpillar technologies, the protocol is fully operational, ready for testing and provides the core technology solutions for further development blockchain eDelivery.

“I see amazing possibilities in the 4THPILLAR TECHNOLOGIES products. The FOURdx, eDelivery serves as a system for sensitive document distribution between organizations and individuals and is based on blockchain technology. A truly innovative and amazing solution.” Igor Zorko, ZZi

Blockchain eDelivery protocol (i.e. FOURdx) — 4thpillar technologies blockchain eDelivery protocol (i.e. FOURdx) leverage trust provided by the blockchain and provides secure, immutable, instant cross-border electronic data and document exchange. The protocol is also capable of; (1) connecting senders and receivers by executing electronic data and documents exchange; (2) performing eDelivery based on the current EU guidelines; (3) archiving securely encrypted data, and (4) following the GDPR guidelines.

Digital Identity mechanism (i.e. FOURid)— Blockchain digital identity mechanism (i.e. FOURid), derives as a direct result of the existing blockchain eDelivery protocol (i.e. FOURdx). The identity mechanism is capable of individual wallet address verification from the authorized third party (i.e. employer, state, motor vehicle licencing department, etc.). A link is created between an individual (or organization) and their wallet, which holds the content and digital assets.

Notarisation Service (i.e. FOURns) — 4thtech notarisation service is able to leverage the power of cross DLT blockchains and facilitate source and time confirmation for digital data and documents. The notarisation function will be soon available for testing as a part of the blockchain eDelivery protocol and will later be an integrated function of 4thtech eDelivery cross-platform client.

Blockchain Gateway (i.e. FOURwaL) — The FOURwaL is a Google Chrome Extension wallet, that allows you to visit the distributed web of tomorrow in your browser today. It is one of our main innovations, a first system on the market capable of handling not only digital assets but also other assets such as links to encrypted electronic data and documents.

“We build the FOURwaL from the ground-up. The challenge was to build the ADD-ON with unique blockchain document exchange feature and it took four engineers over a year to do it. I can say with certainty that the 4THTECH ADD-ON code is unique and first of its kind! “ Denis Jazbec, 4THTECH cto

Transaction bundle — While there are numerous advantages to blockchain networks, there are also issues regarding scaling and transaction fees. Blockchain networks are evolving towards faster, reliable and more affordable systems, but for now, innovative solutions are called upon. To conserve blockchain network transactions, a settlement service was developed, which bundles signed multiple transactions together and settles them on the blockchain (i.e. as one transaction). Once the transaction has been settled, the transaction is concluded. The bundling of transactions enables our platform to scale as the overall number of transactions generated on the designated blockchain network is kept at a minimum.

»The cost of settlement per transaction drops significantly with the number of transactions reaching around 20. « Boris Savic, Olaii
