Explaining the traceability and provenance issues in software supply chains and the work being done, by my team in the Red Hat Office of the CTO and beyond, to improve trust in the software we rely on, as a society.

A general introduction to blockchains and distributed ledger technologies.

If you want to have a currency, you want to have a fungible currency, that is to say, one where each coin can be used in place of any other. The same thing goes for a blockchain-based cryptocurrency. In practice, fungibility means that your blockchain must be able to manage tokens that can change hands without revealing who sent them, who received them or even how many were exchanged, all while guaranteeing that these unknown quantities exchanged by unknown entities were the right ones and not fraudulent ones.

Anonymity, while maintaining trust, is a tall order.

In this talk, we will look at the landscape of blockchain anonymization techniques and where these might be of interest beyond cryptocurrencies, in permissioned blockchains for instance.
