Scusate ma il tema della conversazione segnalata non è se la blockchain sia energivora o meno, ma quanto e se la blockchain (come tecnologia) possa aiutare la "climate governance". Tutto parte dal lavoro di cui è coautrice la Kloppenburg [1] in cui: "In interrogating this dominant storyline, we showed that, far from transforming current modes of governance, it risks privileging further the currently dominant technocratic, market-friendly and procedural approach to multilateral climate governance" A.

Non ho approfondito la questione e non mi sono formato una opinione conclusiva, ma segnalo posizioni che sostengono che il conto della sostenibilità è più complesso di quanto appaia, ad esempio considerando l'impronta del sistema bancario che potrebbe essere sostituito.

Per esempio le blockchain che funzionano con il sistema Delegated Proof of Stake (DPoS) non sprecano lavoro ed energia come quelle Proof of Work. Queste ultime effettivamente sono incompatibili con il pensiero green.

Capisco che per le blockchain proof-of-work questa possa essere una riflessione abbastanza legittima, ma ci sono anche sistemi che usano meccanismi diversi e che non dipendono dal mining. Sbaglio io a considerarle piú sostenibili?

Interessante conversazione tra Evgeny Morozov e Sanneke Kloppenburg [1]
La parte che "mi piace" di più è comunque la fine:
There is, of course, a third, even more radical possibility: the boycott of anything related to blockchains and cryptocurrencies, not least because they have a huge environmental impact. Some scholars, like Pete Howson, for example, have called for global bans (or least limitations) on crypto-mining due to their disastrous impact on emissions (which we probably still underestimate). So, there’s always the option of moving from “blowing up a pipeline” in the colorful formulation of Andreas Malm to “blowing up a blockchain.” What are you thoughts on this more radical option?
Blockchain, like many other digital technologies, does have a huge environmental footprint. There is now an increasing effort to develop guidelines and regulations for the responsible use of digital technologies, for example by the EU and by standard setting organisations. The goal of such guidelines and regulations is to mitigate the societal implications of digital technology. The harmful environmental impacts of digital technologies, however, do not get the same amount of attention yet.
Often the energy consumption of technologies, but also the more systemic environmental risks of using digital technologies, is an externality, which remains invisible and hard to quantify. This is a serious problem, which goes beyond the case of the blockchain, as it also applies to Artificial Intelligence, for example. It is crucial to better integrate sustainability in these efforts to regulate the societal impact of digital technology. The sustainability aspects of technologies should not be an afterthought, but taken into account already when a technology is proposed or designed.
