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
  • April 2020, blockchain eDelivery cross-platform client technical paper publication
    After two years of blockchain eDelivery protocol (i.e. FOURdx) MVP testing, the technical feasibility and its practical potential have been proven, with that PoC (i.e. proof of concept) was confirmed. As the European Union is embracing the benefits of blockchain technology, now is the time for furthered development of blockchain eDelivery protocol (i.e. FOURdx). The development of blockchain eDelivery (i.e. FOURdx) cross-platform (i.e. Windows, Mac OS, Linux, Android, iOS) desktop and mobile client is specified in the blockchain e-delivery cross-platform client technical paper.
  • 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

  • August 2020, the start of SI-Chain partner initiative program 
    Join the SI-Chain initiative and SI-Chain partner testing program. SI-Chain Pilot transactions offer EMV smart contracts and Ethereum compatible dApp environment and as first application electronic data and document exchange and eDelivery .  SI-Chain initiative explores the necessary supporting tools for implementing Blockchain services and outline the technology infrastructures which can support high speed and scalable fourth generation blockchain technology.

“The impulse behind the Blockchain-technology is revolutionary. This new 21-century technology brings online trust, security, privacy, authenticity, synchronise ledger and much more.”

Dr. Tali Rezun, 4ThTech co-founder


Blockchain provides a decentralized and secure shared digital ledger, which gives participating parties a way of validating information related to a transaction.


A network of nodes for digital communications and files exchange, based on a decentralised model where files exchange process runs between blockchain wallets.

2020 & BEYOND

With Active Products & Disruptive Blockchain Services

There is a new technology at the horizon called blockchain, that in its core excludes any intermediary’s, it brings peer-to-peer communication, online trust, security, privacy, authenticity, identity, synchronizes ledger and much more. Could this be the long-awaited solution that could upgrade the internet and how it’s evolving? Read research article and industry overview.

4thpillar technologies infrastructure currently consists of four finished blockchain-based products; (1) blockchain eDelivery protocol (i.e. FOURdx); (2) digital identification mechanism (i.e. FOURid); (3) 4thtech add-on (i.e. Google Chrome extension with build-in asset management), and; (4) four-token (i.e. TTS, MTO & GAS).

After two years of the protocol MVP testing, the technical feasibility and its practical potential have been proven, with that PoC (i.e. proof of concept) was confirmed. We propose further development of the blockchain eDelivery cross-platform (i.e. Windows, Mac OS, Linux, Android, iOS) desktop and mobile client.

The 4thpillar technologies products and services can be applied to various industries, as the need for secure digital eDelivery of sensitive electronic data and documents rises.

According to CEF (i.e. Connecting Europe Facility), eDelivery helps public administrations to exchange electronic data and documents with other public administrations, businesses and citizens, in an interoperable, secure, reliable and trusted way. Blockchain eDelivery has significant advantages, comparing to traditional eDelivery. It is based on a distributed model where the electronic data and documents exchange process runs between blockchain wallets, where private and public cryptographic keys are used for transaction authentication.

Blockchain eDelivery can enable the exchange of value-holding documentation, such as proforma invoice, commercial invoice, certificates of origin, bills of lading, bank drafts, seaway bills, and other types of transport and shipping documentation.

A blockchain initiative for seaborne cargo is a good example of blockchain adoption, aimed at cutting costs and improving cargo tracking. For ocean cargo carriers, blockchain technology allows participants to share information as goods move through maritime focused supply chains, explained (Paris, 2019) from the Wall Street Journal.

According to (Insurance Disruption Using Blockchain Tech l CB Insights, n.d.), there are four major blockchain applications to insurance industry; (1) fraud detection (immutable ledger can help eliminate common sources of fraud); (2) property (shared ledger and insurance policies executed through smart contracts can bring order to property insurance); (3) health insurance (medical records can be cryptographically secured), and;(4) reinsurance (simplify the flow of information and payments)

According to (Blockchain – Perspectives, Insights, and Analysis | Deloitte US, n.d.), blockchain technology has the potential to transform health care, placing the patient at the centre of the health care ecosystem and increasing the security, privacy, and interoperability of health data.





“This new technology allows completely new ways of dealing with sensitive documents. There are thousands of tons of paper that need to be processed to make sure that the employment relations are done properly. With this revolutionary new technology, we can change that! We finally will be able to do our job almost without paper. “

Wojciech Mora, managing director at Work Service Group

In May 2018 Adriatic council awarder Dr. Tali Rezun with the Beyond 4.0 award for his dedication, promotion and accomplishment in the field of science, new technologies and innovation for the 4thpillar technologies blockchain eDelivery protocol.

Project partners are divided into five different categories; (1) public sector partners; (2) private sector partners and supporters (i.e. early adopters, project supporters); (3) marketing and media partners; (4) technology partners (i.e. supporting technologies, blockchain development partners), and; (5) legal, tax, advisory and other.
