A talk at the University of Bonn Computer Science Colloquium. It covers how distributed ledgers (blockchains) combined with decentralised linked data technologies such as Solid can support the management of personal data avoiding the issues highlighted in the media around for example, Facebook and Cambridge Analytica.

The increasing centralization of the Web, he says, has “ended up producing—with no deliberate action of the people who designed the platform—a large-scale emergent phenomenon which is anti-human.”
As highlighted by the Web’s inventor and by recent stories around the Facebook and Cambridge Analytica the over centralisation of, often personal, data generates significant problems for ordinary users. A related problem is that ‘data poor’ citizens can suffer through the denial of credit and more. Recently in the UK over 60 citizens were erroneously deported because of a lack of citizenship data.
At the OU we have been working on a semantic blockchain platform, LinkChain, which supports the decentralisation of personal data by through a combination of blockchain and Linked Data technologies. In the presentation I will give an overview of our platform and show some initial uses within the higher education space.

In this webinar, Alexander Mikroyannidis and Allan Third present the applications of Blockchain in education and the importance of the Semantic Blockchain. They also present their work in the H2020 SlideWiki project, which supports the collaborative authoring of open courseware.

This in depth tutorial, presented at the 2018 International Semantic Web Research Summer School (ISWS), looks at the possibilities for a decentralised semantic web focusing primarily on the relationship between blockchains and linked data. The first part of the talk is an extensive explanation of what blockchains are and how they are used. This is followed by links to ongoing decentralised linked data research including Tim Berners-Lee's SOLID and Ruben Verborgh's Linked Data Fragments.

A joint venture between the Open University and the Knowledge Media Institute.
- The Web has decentralised means of data publication, but no way to guarantee its integrity
- Blockchains can guarantee integrity & timestamping
- We have been exploring the use of blockchains to support Linked Data storage & querying
- In general, interoperability between blockchains and Web standards needs more work
