Overview
In a recent video conference details about 4thpillar’s eDelivery system were revealed. It was hosted by Nena Dokuzov, the project lead for The United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT)UN/CEFACT Chain project.
The 4thtech Co-founder and Council Chair Dr. Tali Rezun, presented his update to the project. The focus of Dr. Rezun’s presentation was on the current problems in the eDelivery system and his team’s proposed solutions.
What is eDelivery
The eDelivery solution is a way to securely share and verify official documents. In the current system, the system implements a data and document exchange protocol where trust is established between two public administrations. After trust between two parties is created, documents can be shared back and forth.
4thtech (4thpillar technologies) enables a blockchain eDelivery protocol to leverage trust directly from the blockchain. Blockchain becomes the verifying authority. The protocol is based on a distributed model where the electronic data and documents process runs between blockchain wallets. In this way, blockchain wallets are used to keep the data secure and verify the parties involved.
Additionally, a verification mechanism has been created which allows individual digital identity to authenticate a connection between a wallet and a person. Tying a wallet to an actual person is very useful in establishing identity for the purpose of sharing documents securely.
Technicals
As a protocol like this is a novel approach, a new system has to be created. The new blockchain proposal is similar to the existing eDelivery model, except this one works on a distributed level. Electronic data and documents are processed between blockchain wallets, using private and public keys used to authenticate transactions. In a way, this is more akin to passing encrypted messages back and forth.
Legal Interoperability
The blockchain eDelivery is fully compliant with the EU’s General Data Protection Regulation (GDPR). Blockchain is used only to encrypt the data on electronic documents, ensuring the receiver can only open the files using their public/private key.
Multi-DLT Interoperability Challenge
The eDelivery system will include blockchain interoperability upon release. It currently works on the Ethereum blockchain and is also deploying on SIChain. The current challenge is expanding this to additional blockchains. Compatibility in a multi-DLT system is an enormous task, one that 4thtech is quickly tackling.
The interoperability is the only present solution, as there is no single blockchain standard for cross-chain compatibility established in the industry.
The project has already created an MVP which is capable of connecting users, securing data, and performing the eDelivery data transfer. This is a strong step forward in creating the new eDelivery blockchain standard. As the project grows in scope, be on the lookout for other advances and announcements on Twitter and Medium.
