Blockchain and Sustainability – Friends or Foes?

Hosted by Walker Morris

The power required to run the global Bitcoin network is estimated as being in the region of 7.5 gigawatts per year.


To put that in to context, that’s the same amount of power required to run 825,000,000 individual LEDs. This then, poses the obvious question – is Blockchain sustainable?

Being one of the hottest topics in tech means that there is the inevitable influx of associated myths and scaremongering. This brings with it the risk that the global community will prematurely dismiss and cast ill-informed aspersions on a technology that has the potential to aid the world’s fight to become more sustainable.

During this session we will look to dispel some of these myths by exploring what Blockchain is, look at its potential future growth and even gain an insight into businesses that have gone one step further by integrating the use of Blockchain into their sustainability-centric businesses.

We will hear from local Leeds start-ups who have sought to harness the indisputable practical benefits of Blockchain, in order to aid in producing a more sustainable world. We will also hear from Anthony Day, a Blockchain Partner at IBM, who helps organisations reap the benefits of edge technology such as Blockchain and guides them on a journey to digitise their businesses.
