The blockchain (distributed ledger technology) is one of the most controversial technologies of the decade. Bitcoin has the environmental footprint of small countries, and is widely considered to be an ecological disaster. Can new blockchain systems offer a better way forward?

We will discuss why these systems are so much greener than bitcoin (with emissions close to those of current cloud systems). With green blockchain technologies in hand, we can build an economy which tracks and pays for all carbon emissions, paving the way for CO2 taxes that will actually work.

There will be an introduction in which Mattereum CEO Vinay Gupta will present Mattereum’s leading edge vision for a blockchain-based Net Zero circular economy which proves the goods and services being sold are truly carbon neutral. His book, The Future of Stuff, outlines the human rights case for a highly transparent economy, and Mattereum implements this vision.

Panel will include Prof. Moriarty, Smart Energy Lead at the Alan Turing Institute.
