The Metroracle project ended in April 2023.
Blockchain oracles compliant with metrology standards
AKA The IoT data ennobled through proven trust
IoT <-> Digital Transformation of Metrology <-> Blockchain
Metroracle system overview
The main parts of a system are IoT devices with sensors that measure data, digital algorithms for metrology that ensure traceability/trustworthiness of measurement and oracles for integration with blockchain.
Various methods and technologies are proposed to establish trust in IoT-measured data. In our opinion, it is necessary to rely on well-defined metrology standards such as WELMEC 7.2 Software Guide, WELMEC 7.3 Reference Architecture and OIML D 31 General requirements for software-controlled measuring instruments.
Digital Transformation of Metrology
Metrology is also exposed to trends and challenges of digitalisation, which was officially recognized in the form of the Joint Statement of Intent "On the digital transformation in the international scientific and quality infrastructure" signed this year by the most important global metrological institutions and is also followed by numerous groups, initiatives, activities and events.
Oracles and blockchain
Although blockchain technology tackles issues of security, authenticity and integrity mainly successfully, there is a remaining weakness of the starting point, i.e. verifying offline data collected through so-called oracles. This is also the case in hardware oracles that collect data measured via IoT devices, which must fulfil all trust and security criteria. This is the primary goal of this proposal - to make IoT devices “oracle-worthy”.
