Listening to a recent episode of the Solarpunk Presents podcast reminded me the importance of consistently calling out cryptocurrency as a wasteful scam. The podcast hosts fail to do that, and because bad actors will continue to try to push crypto, we must condemn it with equal persistence.
Solarpunks must be skeptical of anyone saying it’s important to buy something, like a Tesla, or buy in, with cryptocurrency. Capitalists want nothing more than to co-opt radical movements, neutralizing them, to sell products.
People shilling crypto will tell you it decentralizes power. So that’s a lie, but solarpunks who believe it may be fooled into investing in this Ponzi scheme that burns more energy than some countries. Crypto will centralize power in billionaires, increasing their wealth and decreasing their accountability. That’s why Space Karen Elon Musk pushes crypto. The freer the market, the faster it devolves to monopoly. Rather than decentralizing anything, crypto would steer us toward a Bladerunner dystopia with its all-powerful Tyrell corporation.
Promoting crypto on a solarpunk podcast would be unforgivable. That’s not quite what happens on S5E1 “Let’s Talk Tech.” The hosts seem to understand crypto has no part in a solarpunk future or its prefigurative present. But they don’t come out and say that, adopting a tone of impartiality. At best, I would call this disingenuous. And it reeks of the both-sides-ism that corporate media used to paralyze climate action discourse for decades.
Crypto is not “appropriate tech,” and discussing it without any clarity is inappropriate.
Update for episode 5.3: In a case of hyper hypocrisy, they caution against accepting superficial solutions---things that appear utopian but really reinforce inequality and accelerate the climate crisis---while doing exactly that by talking up cryptocurrency.
Thanks for highlighting it! Never saw it, and now looking into it.
For all I understood, it essentially resembles the banking system, except you have a digital cash option. But other than that, isn't it just integrated into traditional finances, with national currencies and everything? Or is that the point?
Also, from all I understood, Taler is currently a demo and not an actual system for real-world transactions, right?
Kinda. You can think of GNU Taler as a standardized "Paypal" that your bank can self-host and that vendors can implement without having to do something special for each individual bank. In addition it offers cash like privacy protections for buyers.
The EU is currently funding a pilot with two cooperative banks (in Germany and Hungary) to scale this up a bit and NLnet is offering grants for projects like open-source online shop software to implement GNU Taler support.
But it could also be used for things like cash-less payments on music festivals, similar to how you often have to buy paper tokens on those. And of course it is not linked to a specific currency, so you can have many different currencies (even unofficial ones) in your Taler wallet, similar to how you could do that with cash.
Thank you!
I certainly don't like the fact commercial banks are still part of the equation here. To me, the system should either be controlled through a central bank, or use a network of decentralized middlemen (like crypto does), though the latter may be inefficient. Commercial banks are cancer.
I'm also riddled with the technical details of it, in that transactions rely on blind signatures instead of blockchain.
How do blind signatures replace some sort of ledger? Or is it still kept somewhere somehow? Did Taler solve the issue of locally storing money in a way that they can't be tampered with?
Central banks could certainly also be Taler exchanges, in fact the Swiss central bank published a paper on exactly that and their outcome was: yes feasible but we don't need that right now.
As for commercial banks: I think it is worth differentiating there a bit. IMHO cooperative banking is exactly the kind of decentralised structure you seem to want, yet technically you lump them with other commercial banks. Currently both banks that participate in the GNU Taler pilot are strong examples of coop banks. I was quite positively surprised when they announced the participation of these two banks.
As for the technical questions: you are looking at it through the warped perspective of blockchain. None of these issues are real and in fact had been solved long before block chain was even invented. They only become an issue when you enter the realm of "let's pretend you can create an trustless system", but that's starting from a wrong premise.
Thanks for the answer! I'll do my homework on that.
If a government is backing it, color me skeptical on the privacy claims.
Its all open-source and well documented, and they make it very clear that sellers have strict built-in transparency, which is really what governments care the most about (for tax purposes).
So the privacy protections for buyers are very real and something most democratic governments actually support, no conspiracy required.
That's still a very different understanding of governments than I have.
The lack of privacy is one of the founding principles of the project. There is no privacy for the merchants.
This presentation does a good job of explaining it. The gist of it is:
But I just learned of it from this thread as well, so that's just what I've gleaned so far.
Thanks for the link!
