       | Seems like a lot of work to offer a less functional alternative
       | to a VISA gift card purchased with cash.
       | 
       | The only real advantage I see is you don't need to stop by
       | WalMart. Maybe the activation fees with Taler are less but I'm
       | sure it's also less widely accepted.
       | 
       | VISA eGift cards are now available for purchase online with funds
       | deposited to a digital wallet. These won't be totally anonymous
       | but then as far as I can tell, neither is Taler --- to provide
       | all the functionality they claim, they will need to maintain
       | records of both purchaser and merchant.

         | In addition to the huge advantage of not needing to get cash
         | from an ATM and physically carry it to the card vendor:
         | Transactions made on the same eGift card wallet are tied
         | together. With Taler you have a wallet with coins you can spend
         | separately, and which cannot be correlated, neither by your
         | bank nor the merchant. What makes you believe anyone (except
         | maybe the purchaser themselves) needs to maintain records about
         | the purchaser? As far as I understood it, their claim is that
         | exactly this is not necessary.

           | Unless you buy your digital coins using cash, the exchanges
           | have the identity of those who purchase and redeem
           | coins/tokens.
           | 
           | From the documentation:                 Taler is compatible
           | with anti-money-laundering (AML) and know-your-customer (KYC)
           | regulation, as well as data protection regulation (such as
           | GDPR).
           | 
           | AML and KYC are all about removing anonymity. Merchants may
           | not have the ability to correlate a purchase to you but the
           | exchanges do; otherwise, they wouldn't be able to comply.

       | This comes up every so often on HN, it's been in development for
       | a while. I do see at least some technical work happening in Taler
       | (https://taler.net/en/news/index.html) so it doesn't look like
       | the project is dead, but I'm having a hard time finding a
       | roadmap.
       | 
       | What is the overall state of Taler today? How close is this to
       | being something tangible that I can hand to my parents where they
       | can actually make real payments with it for an online product?
       | Are there any businesses supporting it as a payment method yet?
       | 
       | I vaguely remember last time I checked that it was still trying
       | to get buy-in from banks? But I could be remembering wrong.

         | GNU Taler is a nice software project. The problem with privacy-
         | preserving centralized payment systems is that "writing
         | software" remains the relatively _easy_ part of the deployment
         | puzzle: in practice you need to convince centralized banks and
         | payment systems to deploy it for some application.
         | Unfortunately, cryptographers have been trying to do this since
         | the 1980s and DigiCash... with extremely limited success.
         | 
         | Decentralized payment systems have changed the equation and now
         | we're seeing a great deal of progress in the area of privacy-
         | preserving payments, some for better and some for worse. I wish
         | Taler could find some applications over there, but the
         | developers don't seem interested. Which is only fair.

         | There is no public roadmap on the business side as the
         | commercial banks we are talking to are not yet willing to have
         | their names disclosed to the public. They're rather
         | conservative institutions (by nature), so they want things to
         | be checked and double-checked and ready to go before going
         | public. Plus it is not trivial (for them) to check all of the
         | regulatory, technical and business checkboxes. I remain hopeful
         | that we'll get through this mess "soon", but I've been too
         | optimistic in the past.
         | 
         | What I can say is that we have presented GNU Taler to over a
         | dozen central banks already. We're trying to convince them that
         | they must give citizens privacy and that an account-based
         | system would give them too much power.
         | 
         | So while the business side is not exactly transparent, what we
         | do technically is all out there. And it's not necessarily a bad
         | thing to have some extra time to reduce the list of known bugs
         | before we go live. :-)

             | Given that for many larger banks, medieval things like
             | overdraft fees and "re-ordering" same-day transactions so
             | that deposits appear later in order to create additional
             | overdraft fees are a huge part of their bottom-line, it

             | control to an open and fair standard they can't override.
             | 
             | Also, I'm sure anti-money-laundering legislation
             | complicates things in terms of the anonymity feature,
             | despite the fact that merchants are fully auditable, though
             | I assume users aren't able to transfer funds to non-
             | merchants? Still, I'm sure the laws as written complicate
             | this in some jurisdictions.
             | 
             | For example, you could have a completely legitimate
             | business registered as a merchant function as a money-
             | laundering front that could then take in illicit funds from
             | anonymous users working for the illicit org which actually
             | secretly owns the merchant. I'm fine with that happening in
             | the wild because the benefits of privacy for consumers are
             | obvious to me and outweigh the negatives, but I bet
             | regulators aren't so forgiving.
             | 
             | In the wild this often happens -- there are plenty of "DDoS
             | protection" services that by day offer legitimate services
             | in the open and by night actually attack potential
             | customers who they then offer their protection services to,
             | so it is not at all unheard of for an illegitimate org to
             | have a legitimate front. This sort of thing is rampant in
             | the world of high-end minecraft servers, I'm told.

           | I know you can't give more definitive timetable or details
           | about actual negotiations, but at a high level what does "get

           | goal that Taler is trying to achieve for how it initially
           | enters the market? Is it possible I wake up one day X
           | months/years from now and just see an announcement that a
           | bank has now decided to use Taler and it'll go live next
           | week, or is this something that's expected to be much more
           | gradual in its rollout?
           | 
           | I don't feel like I have a great understanding of what the
           | process for adoption for Taler looks like beyond the long-
           | term goal that banks would start supporting it and then
           | merchants would follow. I'm not sure if the plan is:
           | 
           | - a bunch of private negotiations happen, and then there's a
           | breakthrough and suddenly within a year half of the banks are
           | using it, or
           | 
           | - a bunch of smaller organizations take it up, and it starts
           | out more niche and starts to grow, or
           | 
           | - somebody someday starts a Paypal equivalent that isn't even
           | technically a bank, just a payment app.
           | 
           | I guess given that Taler is in talks with banks, the hope is
           | that it gets adopted first with those banks; so is the goal
           | that if talks are successful the rollout _starts out_ at an
           | almost national scale?

       | Pulling this off in the United States sounds somewhere between
       | very challenging and impossible.
       | 
       | Sales tax is not uniform. Rates vary not only by state but also
       | at a local level. In some states, sales taxes can be imposed by
       | the state, by counties, by cities, by school districts, by
       | transit authorities, and by other entities like special purpose
       | districts[1].
       | 
       | Which ones (plural) of these sales taxes (plural) apply to a
       | transaction depends on the _buyer 's location_.
       | 
       | In many cases, knowing the buyer's city, state, and zip code is
       | _not granular enough_. For example, the boundaries of a school
       | district may not correspond to zip code or city.
       | 
       | The typical approach today is to collect the buyer's full
       | address. From that, there are databases that will tell you the
       | list of jurisdictions and taxes that apply. Obviously, that's not
       | very anonymous.
       | 
       | Maybe you could have the buyer determine all of the
       | jurisdictions/taxes that apply to them and send only that info
       | instead. That's less granular, but in some cases it might give
       | away a lot of information. (Sort of like browser fingerprinting.)
       | 
       | But if you do that, I'm not sure what the implications would be
       | for sellers. Sellers are required to collect the sales tax and
       | remit it to the state. They can get in trouble for not doing it
       | right. Governments don't like it when their taxes don't get
       | collected, so they sometimes create laws that put the burden of
       | compliance on the seller.
       | 
       | ---
       | 
       | [1] Special purpose districts could allow a county or local
       | government to, for example, pick an arbitrary area and impose a
       | sales tax within it just to support libraries that serve that
       | area. Or crime prevention, road improvement, emergency services,
       | hospitals, parks, economic development, etc.

             | I find this very defeatist, and this attitude becoming

             | unabated.
             | 
             | Perhaps it's true that this is the type of system that
             | governments and banks might be willing to introduce today.
             | Afterall, privacy in financial interaction is not
             | acceptable to the mainstream institutions. Over the last
             | century, and especially since the early 1990s, the Overton
             | window has shifted toward greater state control and less
             | privacy. The proof of this is in the fact if cash were
             | introduced today, it would be made illegal. And instead of
             | pushing back against this trend toward mass-surveillance,
             | Taler cows to it, with ideological rationalizations to
             | boot.

             | Cryptocurrency has a real potential to reverse the trend
             | towards a dystopian surveillance state controlled by a
             | handful of governments and payment processors, and the

             | political ideology, and visions of taxing every one, to
