Richard Stallman Criticizes Bitcoin, Touts a GNU Project Alternative (coindesk.com)

Richard Stallman doesn't like bitcoin, and has never used it, reports CoinDesk: To Stallman, bitcoin isn't suitable as a digital payment system. His biggest complaint: bitcoin's poor privacy protections. He told CoinDesk, "What I'd really like is a way to make purchases anonymously from various kinds of stores, and unfortunately it wouldn't be feasible for me with bitcoin." Using a crypto exchange would allow that company and ultimately the government to identify him, he said.... Asked what he thought about so-called privacy coins, Stallman said he'd gotten an expert to assess their potential, and "for each one he would point out some serious problems, perhaps in its security or its scalability." And speaking broadly, Stallman continued: "If bitcoin protected privacy, I'd probably have found a way to use it by now."
Fortunately, Stallman's GNU Project has a better answer: The GNU Project, which Stallman founded, is working on an alternative digital payments system called Taler, which is based on cryptography but is not -- forgive the hair-splitting -- a cryptocurrency. The Taler project's maintainer Christian Grothoff told CoinDesk that the system is, rather, designed for a "post-blockchain" world.... It's based on blind signatures, a cryptographic technique invented by David Chaum, whose DigiCash was among the first attempts at creating secure electronic money. Plus, Taler's attempt to create a digital money that resists surveillance by governments and payments companies aligns it with many cryptocurrency projects.

Yet, Taler does not attempt to bypass centralized authority. Payments are processed by openly centralized "exchanges" rather than peer-to-peer networks of miners because, Grothoff said, such a system "would again enable dangerous, money laundering kind of practice." Indeed, in a break with the anti-government ethos that has tended to characterize bitcoin and some of its peers, Taler's design explicitly tries to block opportunities for tax evasion.... Privacy in the Taler system, then, is limited to users spending their digital cash. They are shielded from surveillance because, Grothoff said, "the exchange, when coins are being redeemed, cannot tell if it was customer A or customer B or customer C who received the coin, because they all look identical from the exchange. Nobody," he added, "exactly knows who has how many tokens." Merchants (or anyone) receiving payments, on the other hand, do so visibly and in the open, making it possible for governments to assess taxes on their income -- not to mention harder for the recipients to participate in money laundering....

Currently, Taler is in talks with European banks to allow withdrawal into the Taler wallet and also re-deposit from the Taler system back into the traditional banking system.
"I wouldn't want perfect privacy," Stallman says in the interview, "because that would mean it would be impossible to investigate crimes at all. And that's one of the jobs we need the state to do."

lol...Blind Signatures

[NicknameUnavailable]

The funny thing about them, is they're even WORSE than existing crypto algorithms. We have a hard deadline of 2023 before quantum computers can break pre-quantum algorithms with vary slightly modified versions of Shor's algorithm based on a decade-old linear trend in qubit count. That means we are looking at just a few years to get everyone switched over to post-quantum algorithms. Post quantum algorithms are largely shit because they have at absolute best (smallest) signature sizes of 31KB, which has it's own set of issues (specifically, about 4-8TB/year of signatures on transactions which you can never delete without voiding the integrity of the blockchain, which from a logistical standpoint will lead to centralization.) Post quantum algorithms have another MAJOR failing: there is no such thing as a post-quantum algorithm which supports blind signing. It can't be done in a provably secure manner, there is some (very sketchy) research suggesting lattice based cryptographic algorithms MIGHT get there, but there is no proof those are even secure against traditional computers at the current level of development.
TL;DR: This is FUD, there are no post-quantum blind signature algorithms known at this time, at least systems not relying upon blind signing have some (terrible) methods available to them to patch the system and make it post-quantum safe, something based on blind signatures doesn't even have a roadmap beyond the next 4 years.

Bitcoin is not a payment system.

If you think Bitcoin as a payment system, you are missing the point. Bitcoin is a store of value; 'Lightning' is the payment system of Bitcoin and 'Lightning' can scale without issue. 'Layers' are the answer.

Why Use It?

[mentil]

Wait so Stallman wants privacy, but also wants the State to be able to investigate crimes? That sounds suspiciously like "privacy for my use case and noone else's". Furthermore, being able to send money anonymously STILL allows money laundering: "Yeah I sent that money to my restaurant chain, employees paid in cash. Why no I don't own any banks in the Caribbean, why do you ask?"

No, that sounds like cash. What Stallman objects to is people like Visa and Mastercard getting to monitor all your transactions. It's privacy from payment processors and from the kind of "automatic" surveillance that comes with it.

Cash is semi-anonymous. You don't have to reveal your ID for a lot of transactions with it, but sometimes do if you need stuff like delivery or are buying certain services. There are systems in place to make sure merchants don't cheat the system to avoid taxes or launder money too, although they might not be that effective. Bitcoin doesn't really improve on that, and neither does Taler.

What Taler does is scale and integrates with the law enough to be widely adopted by legitimate businesses, especially financial services like banks. It's also not tied to mining so doesn't waste vast amount of energy or act as a scam for early adopters.

Not really. He wants the state to be able to see who receives money (so they can properly assess income tax and VAT), but not where that money is from. The state can see that I got 5 talers from you (and if I don't declare them they can ask questions about that). They can see that Pornhub received 5 talers for access to certain videos (and charge them the right VAT on that transaction). But they cannot see where I spent my 5 talers. Assessing taxes on monetary transactions is the state's business, but where I spend my money isn't. It also isn't anyone else's business. This coin supposedly is an answer to that problem.

As for it not being peer-to-peer: most people don't give a rat's arse about that: they want to be able to spend anonymously using a mechanism that allows for instant and cheap transactions. Likewise, banks like the idea of an easy, fast, cheap mechanism for settlement. The real question is: can it deliver on that score?

Crypto is a hipster tech trend. Claiming you don't want a CoC and then putting up one (not as bad as Linus but still) which demands gender neutral pronouns is an SJW techtrend. Stallman has done both more and more over recent years.

In other words it's like cash. Semi-anonymous, but the shops you spend it in can be regulated.

Actually, cash makes tax evasion a lot easier than this system. That's why some businesses like cash.

Personally, not being a criminal, I'm with Stallman: privacy to prevent companies from building and selling profiles of customers is good, but privacy for tax evasion is bad and I'm happy for the government to have the ability to round up those bastards. Technically illegal purchases are private under this system, but fortunately when the police raid the criminal merchant they're likely to discover the customers through other means.
