Experiments with the Ethereum Blockchain

Ethereum is a platform for decentralised applications, built on top of a blockchain mechanism, which can be used for public data storage and computation. It acts as an immutable public ledger, which provides strong cryptographic guarantees for data integrity. One definitive feature of the Ethereum platform is the ability to execute Turing-complete Smart Contracts. A Smart Contract is a program on the blockchain. We have been investigating the possibilities that the Ethereum blockchain infrastructure affords.

Below you can see some screencasts of some of our recent experiments with Ethereum:

Open University in £40m campaign to create more computer scientists

The Open University in Milton Keynes is at the heart of a £40 million drive by the Government to help train more computer scientists. It is leading one of the five main themes – on university learners – being addressed at the new Institute of Coding.

Using Blockchains and Semantics to Decentralise Personal Data

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.”
Vanity Fair Quoting Sir Tim Berners-Lee August 2018.

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.
