Bitcoin GNU is Not Unix Privacy The Almighty Buck

Richard Stallman Criticizes Bitcoin, Touts a GNU Project Alternative (coindesk.com) 289

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."

      Ahm, that is not really a 'hard deadline'. Some prognosticators believe there will be a usable quantum computer that is more economical than simulating the same process on a conventional system, but there is no telling how close to the mark they will be. It is quite possible quantum computers will never be useful. So not really a hard deadline, not even a soft one, just an estimate based off people's hopes.

So in other words we have a boondoggle johnny come lately with the worst of both worlds neither the governments or the antigovernment side wants or needs. Maybe Stallman fried his brain some years back toking MJ and thats why he's changed from OS pioneer to jumping on and trying to split the difference on every hipster and SJW tech trend these days.

      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?
    • The state should have reasonable ways to investigate crimes that involve large amounts of money. Right now a lot of crimes like kidnapping for ransom are effectively impossible to do because the payout can be traced (even with cash, by serial numbers on banknotes). A truly anonymous currency makes them possible.

      What is a good use for anonymous currency anyway? Buying drugs and hookers?
      • by jythie ( 914043 )
        Outside crime, cryptocurrency value is generally not in its actual utility, but its emotional impact on the user. People do not use it because it is cheaper or quicker or a better system, but because it scratches a certain ideological niche, which is why you mostly see it being used by people who can afford to be wasteful.
        • It's definitely faster for merchants. Bitcoin for instance settles in roughly 10 minutes. Except in extraordinary circumstances which might take two hours. Visa or Mastercard, by contrast, enforce a six-month window where you never know if the payment is finalized or not. That's crazy for merchants, but Bitcoin doesn't have that problem.

            So how do I get a refund on a Bitcoin purchase? Oh, yeah. I can not.

            You also misunderstand how VISA works. The settlement time in the VISA network is 7 days. So once I sell something I can expect money in my bank account within 14 days.

            VISA allows for 6 month chargeback window for customers. If a customer's bank issues a chargeback then the merchant's bank is legally required to wire money to the customer's bank. But this is a separate transaction, unrelated to the settlement itself.

    Seems nobody who's into alternative currencies, whether "blockchain" based or not, understands the principle by which money gets and retains its value, even though it's perfectly simple. No, it's neither by government decree nor by belief, that would be too simple, but then again it's only slightly more complex. It is by the objective trustworthiness of the promise that money invested in the currency area will come back as more money, meaning how reliably the promise is backed by the industry's profitability and growth within the currency area. Any alternative currency needs to be widely established and used in production, commerce and the payment of wages, before it gets such an ability, or the value needs to be fixed to an existing 'real' currency with an institution that can reliably guarantee the exchange into that currency.

      The only trust required is not in the value of Euros or USD or whatever stored in the wallet, it's that the wallet itself is secure and you no-one can alter the balance without making a legitimate transaction.

    So, Monero/Dash/ZCash/dozens others are not enough according to Stallman and thus he intends to create the 4000th cryptocurrency which will be the "best" among all of them instead of fixing the existing ones which have nodes/users/miners behind them.

    Stallman is absolutely right to draw attention to the privacy-stripping nature of crypto-currency, but this is far from the only challenge that this type of model can experience.

    As we saw in Bitcoin trading in early 2018, an even greater threat may be speculation. Earlier this year, investors and speculators all "piled in" to Bitcoin, driving up the value of coins as demand far out-stripped supply. Now, less than a year later, the value of Bitcoins is tumbling to about $3,750, roughly 20% of the value it held at the beginning of the year. That's a shocking rate of loss.

    It is worth mentioning the "speculation risk" with respect to crypto-currency, because there is nothing that Mr Stallman has said which gives any indication that his GNU Project Alternative would in any way mitigate the risk of speculative trading. An only slightly smaller annoyance than the speculators would have to be the conversion fees charged by the so-called "Exchanges".

    As this MSNBC report from last December [cnbc.com] shows, some exchanges were charging an average of $28 per transaction. There are examples of people being charged $15 to send $100 in value - which is ridiculous.

    This is frustrating for many reasons, not least of which is the fact that Bitcoin briefly had the potential to be something that could bring down the banking hegemony on currency conversions: you convert some of your local currency to Bitcoin for next-to-no overhead... you fly to another country... you convert your Bitcoins to local currency for next-to-no overhead. This, had it come to pass, would have allowed Bitcoin to become quickly established in the world and to also force established financial institutions to offer fairly-priced products instead of creaming fat profits off of travellers.

    So even though I'm sure that Mr Stallman and his colleagues will have done some excellent work on enhancing the privacy of their alternative crypto-currency, the simple fact remains that privacy is just one of a multi-faceted problem. In fact, it's entirely possible that different exchanges, working in concert, could price this new offering out of the market by demanding even higher transaction fees (on the basis that they are not getting marketing information out of their users).

    The entire "marketplace" looks to be increasingly rigged by "establishment middlemen". Sadly, I don't think that there is any way of circumventing that, at least not within the scope proposed here.

    • Governments and entities (e.g. Visa) can arbitrarily and capriciously block an individual or organization's access to money. E.g. (Swift blocks, Wikileaks)
    • Transferring money over the internet requires an expensive intermediary. (E.g. Visa, Paypal)
    • Transferring money over the internet is subject to chargebacks, freezes, and holds often with no recourse. (E.g. paypal account freezes)
