Blockchain Catch-upThis is a Charles Brett’s start-of-the-week Enterprise Times ‘blockchain catch-up’ Week 20. Necessarily it is idiosyncratic and selective.

It is not intended to be comprehensive but does seek to highlight ‘Quick Takes’ on specific developments as well interesting pieces to read, a listing of some (not all) announcements/press releases and pointers to upcoming events.

Quick Takes – Charles Brett’s Blockchain Catch-up Week 20

Bitcoin’s growing energy problem: ‘It’s a dirty currency’

According to an FT Long Read: to academics who for years have been measuring bitcoin’s energy intensity, (Elon) Musk has simply pointed out an established truth, albeit in his eccentric manner. It is a question so far largely ignored by governments, by heavy-hitting environmental charities, and by the banks and exchanges that facilitate the vast cryptocurrency industry. “Bitcoin alone consumes as much electricity as a medium-sized European country,” says Professor Brian Lucey at Trinity College Dublin. “This is a stunning amount of electricity. It’s a dirty business. It’s a dirty currency.”

Quick Take: This is, in effect, an expansion of Gillian Tett’s comments on Bitcoin (q.v. last week’s (Week 19’s) Quick Takes). It goes into further detail and it is about more than the Bitcoin element in the title. Though it is behind the FT’s paywall, it is worth trying to access it as it brings together several dimensions relevant to blockchain and crypto-assets. For example, the FT points out that the European Central Bank (ECB) described cryptoassets’ “exorbitant carbon footprint” as “grounds for concern”. In comparison, Italy’s central bank recently described the eurozone’s payments system, Tips, as having a carbon footprint in 2019 that was 40,000 times smaller than that of Bitcoin.
