4thpillar technologies updates

  • February 2020, SI-Chain partnership
    4thpillar technologies joined the Slovenian national blockchain testing infrastructure called SI-Chain. The Si-Chain implementation of 4thpillar technologies electronic data and documents exchange protocol and identity mechanism is underway. Supported by Slovenian Ministry of Economic Development and Technology, powered by HashNET and Telemach, Si-Chain was established in November 2019 with the intent to enable testing of existing and new blockchain applications for the public and private sector.

  • April 2020, 4thtech and HashNET consortium
    Supported and approved by Slovenian Ministry of Public Administration, the consortium was formed between 4thpillar technologies and HashNET, to enter the INEA 2020 CEF Telecom Call with the blockchain eDelivery solution and SI-Chain implementation. More information
  • May 2020, CEF Telecom Call - eDelivery (CEF-TC-2020-1) application

    We have submitted CEF Telecom eDelivery Call application, with the objective to develop and deploy cross-platform eDelivery client, a DSI with a unique Access Point, that will leverage blockchain for electronic data and documents exchange. 

  • June/July 2020, SI-Chain deployment
    Si-Chain deployment of 4thtech electronic data and documents exchange protocol.
  • July 2020, 4thtech at Virtual Workshop Towards Global Interoperability Blockchain Infrastructure in Geneva

    UN/CEFACT Chain - Guidance for cross border interoperable blockchain infrastructure 4.0 was presented along with selected use cases on the 9th of July in Geneva. 4thtech eDelivery use-case presentation was presented at 12:00 (Geneva time). More information

  • September 2020, publication of 4thtech MVP Short Paper 1.0
    As the completion of fully-featured 4thtech MVP (i.e. FOURdx, FOURid, FOURns) is close, we have prepared the project MVP Short Paper, that provides further and deeper project understanding. Follow the link and download the Short Paper
  • September 2020, Notarisation service deployment
    According to the plan, the 4thtech notarization service is operational and able to leverage the power of cross-DLT blockchains to confirm content authenticity and timestamp. To illustrate the notarisation process, the video notarisation tutorial was prepared, please follow the link.

Project Overview

In 2017, 4thtech proposed and later developed a DLT solution, which leverages trust provided by the blockchain to provide secure, immutable, instant cross-border electronic data and document exchange and eDelivery (i.e. FOURdx). The identification mechanism concept (i.e. FOURid) later followed in 2018, which can with the help of X.509 EU certificate standard verify the 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 document timestamp and authenticity verification.

4thtech MVP developed solutions (i.e. FOURdx, FOURid, FOURns) provide the rationale and framework needed for further 4thtech cross-platform client development, legislation adoption, cross-chain deployment and recognition. The completed fully-featured 4thtech MVP also concludes projects second biggest development mile-stone and paves the way towards the final goal, that is the development and deployment of 4thtech cross-platform client (i.e. Windows, Mac OS, Linux, Android, iOS). As we are closing in on the project's 3rd anniversary, the fully-featured MVP is near completion.

After two years of use-cases MVP (i.e. minimum viable product) testing, the technical feasibility and its practical potential have been proven, with that PoC (i.e. proof of concept) was confirmed. With further development, 4thtech solutions will be merged into a cross-platform desktop and mobile client (i.e. Windows, Mac OS, Linux, Android, iOS) and provide the technology for further wider adoption compatible and in line with European Blockchain services infrastructure and usable or extendable globally. 






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 (or organization) wallet address verification. A link is created between an individual (or organization) and their blockchain wallet within the 4thtech system. The identity mechanism is also capable of; (1) connecting the X.509 standard digital certificate with blockchain wallet; (2) providing the digital identity for blockchain eDelivery (i.e. FOURdx), and; (3) providing digital identity for blockchain Notarisation (i.e. FOURns).

As main 4thtech MVP solution, 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 fully-featured protocol is capable of; (1) connecting senders and recipients by executing blockchain electronic data and documents exchange (i.e. blockchain eDelivery); (2) performing blockchain eDelivery based on the current CEF (i.e. Connecting Europe Facility); (3) archiving securely encrypted data and documents off-chain, and (4) following the EU GDPR guidelines.

4thtech notarisation service is a by-product of eDelivery protocol (i.e. FOURdx) and digital identity mechanism (i.e. FOURns) and is able to leverage the power of cross-DLT blockchains to facilitate source and time confirmation for digital data and documents. The 4thtech blockchain notarisation service is also capable of; (1) storing and timestamping a digital data or document; (2) providing the verification of the digital data or document authenticity, and; (3) providing access and review of the notarisation details.

With a single purpose, the 4thtech wallet serves as a blockchain gateway, a tool for blockchain application access. It provides the simplest but secure way to connect to the 4thtech blockchain applications (i.e. digital identity, eDelivery and notarisation) as it contains a pair of public and private cryptographic keys. A public key allows for other wallets to execute 4thtech services to the desired wallet’s address, whereas a private key enables the decryption of electronic data, documents and notarisation details from the sender address.
