For national and international climate data services it is quite a challenge to generate transparent complete and nevertheless compact information on the quality of datasets and their suitable application domains. Next to statistical properties of the dataset and its variables as such, the tractability of the data generation process is important. Blockchains technology could be of help in the management of tractability of data generation pathways.
On May 16, 2018, researcher Tommi Vuorenmaa, Co-Founder and CEO of Aekraes Kodex (Helsinki, Finland), clarified the properties and prerequisites of blockchain technology, and provided some thoughts on the application in the field of climate data services during the CMCC webinar “Can block chains have a role in climate data quality management?”.

Blockchains technology could be of help in the management of tractability of data generation pathways. Essentially, blockchains enable the provision of watertight evidence on how the current condition of an informational product has been generated via all previous transaction (processing) steps. To this end blockchains need support from protocols that certify the reported state of the information in a designated transaction step. In other words, the applicability of blockchain technology depends to a large extent on the ability to describe unambiguously and consistently underlying processes on the basis of shared principles and standards.
