Recheck Green Box Has Been Selected as One of the Brightest Projects for Building THE NEXT GENERATION INTERNET in Europe

Recheck is taking part in Ontochain, to co-develop a new software ecosystem for trusted, traceable & transparent ontological knowledge

ReCheck is taking part in ONTOCHAIN, to co-develop a new software ecosystem for trusted, traceable & transparent ontological knowledge. The project aims to implement a digital logbook for managing the trusted history of the buildings on the blockchain. The solution will guarantee that the essential design and operational information will belong to the buildings, is reliable, and can be easily accessed and verified.


ONTOCHAIN is a new software ecosystem for trusted, traceable & transparent ontological knowledge management funded by the European Commission as part of the Next Generation Internet initiative (NGI).  

ONTOCHAIN empowers internet innovators to develop Blockchain-based knowledge management solutions that address the challenge of secure and transparent knowledge management, as well as service interoperability on the Internet.

The ONTOCHAIN software ecosystem aims to demonstrate its potential in high impact domains, such as eHealth, eGovernment, eEducation, eCommerce, decentralised infrastructures and similar, in order to achieve trustworthy information exchange and trustworthy and transactional content handling.


ReCheck Green Box is a digital building logbook that aggregates, normalises and secures online and offline data about buildings. In its current state, the solution is normalising input from devices from a variety of vendors using different protocols for data exchange. The normalised data is pushed to a secure data vault as an immutable and timestamped record which can be polled and verified directly against digital trails on a decentralised ledger. The data is also visualised in a flexible dashboard system accessed through a multiuser web-based environment. The users are in a position to track every change related to the building of interest and can access historical records secured by blockchain. The internal normalisation model includes data structures that would benefit from the ontology foundation provided by OTNOCHAIN and become understandable for other systems’ data sources or data stream providers.

ONTOCHAIN Open Call 3 was looking for interoperable and sustainable applications that employ Semantic Web and Blockchain concepts, to enhance data quality aspect, as well as the trustworthiness of data communication and handling processes. 

Web3 innovators were invited to propose applications covering real needs of end users in vital sectors of the European economy, built on top of the software services of the ONTOCHAIN ecosystem. Applicants could also submit proposals around missing blocks of the ONTOCHAIN infrastructure.

A total of 105 projects applied for the call and the evaluation process resulted in the selection of 14 proposals addressing the following topics:


  • Service Integration (Gateways APIs) for ONTOCHAIN applications
  • Energy-efficient and sustainable hosting infrastructure for the ONTOCHAIN software ecosystem and services


  • Semantic Digital Logbooks for Companies, Buildings, Cars or similar
  • Decentralised Fact Checking and Data Credibility for Social Content
  • Semantic energy data management
  • Automotive, e.g., electric vehicle charging, road side management, car insurance, communication interoperability
  • Distribution Logistics / Supply Chains Using Trustworthy Semantic Data
  • Data/Digital content /Multimedia marketplace, including social media
  • Decentralised Public Services & Common Goods
  • Other applications aligned with ONTOCHAIN objectives

ONTOCHAIN will support ReCheck through a 10-month programme and provide funding support up to 119.500 Euros. As part of the action, experts in diverse fields will also provide technology development guidance, working methodology, as well as access to top infrastructure, coaching, visibility and community building support.
