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.
