The project was focused on industrial research and development work aimed at creating an infrastructure based on Blockchain technology, used to build systems for digital identification. Thanks to this technology, it was possible to build a system that is characterized by data transparency, non-repudiation, authenticity, uniqueness, durability and decentralization. For digital identification solutions, however, was is necessary to enrich this technology. In particular, the following steps were recognized as necessary:
As a result of the work, a product was created, which was characterized by the following features:
As a result of GraphChain a scientific paper was prepared – “A distributed database with explicit semantics and chained RDF graphs”. A paper submitted to LD-DL III, April 2018, Lyon, France © 2018 Association for Computing Machinery.
In this paper we have presented a new idea of creating a Blockchain com-pliant distributed database which exposes its data with explicit semantics present and easily accessible and which applies Blockchain securitization mechanisms to the RDF graph data model explicitly, without additional packaging or specific serialisation.
Graphchain 1.0 was sucessfully implemented in our flagship project Legal Entity Indentifier – Lei.info where LEI data stored in the semantic format can be verified in blockchain Hyperledger Indy.
Grapchchain 1.5 – Evolution towards Graphchain 2.0
In 2019 we have applied to The National Centre for Research and Development with the project: “Realization of industrial research and development activities aiming at the creation of a software framework enabling the construction and deployment of Blockchain based systems and applications for modern, high-performance graph databases.”
The goal of the project was to continue a research and development aiming at the creation of qualitatively new categories of software solutions in the DLT (Distributed Ledger Technology) and Blockchain domains, which would allow the fundamental features of these solutions to coexist with modern graph databases of the LPG (Labelled Property Graph) type.
Despite the fact that our application was not approved it has become an impulse to continue research on this topic.
