Is there some sort of an overview of all the components that are required for the whole system to work? Are there opportunities for new PSPs to emerge and try to topple the existing ones with better and cheaper service?

If you want to exchange official fiat currencies you need something that libeufin can talk to via the standartized banking api. Everything else is included in Taler and ready to be used with unofficial regional currencies for example.
I hope this takes off. MasterVisa censors pornographic stuff, denying payment services for people who don't normalize their creations. On top of that, MasterVisa will likely become collaborators of the Trump Regime, tracking payments of anti-trump folks, denying service to clinics that provide healthcare to women and minorities, ect.
Privacy is extremely important for the safety and liberty of people.
GNU Taler has been specifically designed to allow authorities to control (or at least monitor) the flow of money, though.
Provided enough members of the EU don't agree about the evils of sexual preference, that is less of a problem than MasterVisa.
Mind, I would prefer true privacy coin like Monero to become big, so that we can just have digital cash and be done with it. No gods nor kings, just us getting on with our business, whatever that may be.
The ECB also wants to introduce a digital Euro. I wonder how exchanging my digital Euros to digital Swiss Francs and vise versa would work. Currently with physical cash you need to exchange your money at an intermediary. But with digital coins itβs surely possible for the national bank to handle this.
If you ever paid with your card in a non-Euro country, you already did something like that.
Revolut will on the fly convert between your currencies on the fly.
Cyberpunk is now, old man.
It is very easy lol but it's likely Mastercard/Visa doing the conversion (taking ~ 0.5% each time), exactly what we want to avoid :P
It aims to be as privacy preserving as cash for the buyer while not allowing the seller to evade taxes.
So I could buy a VPN with it and then order some Swedish porn (edit: life streams), and no authority would be able to track me down?
Basically yes, but the seller needs to register a business account with a Swedish Taler bank exchange, and if that bank figures out that the seller is breaking Swedish law they can terminate that account.
Why would anyone want to track you down for watching porn?
Ask the Swedes, they're the ones being weird about it
In Sweden you can buy porn but you are not allowed to buy life streams and tell actors what to do to prevent abuse of power imbalances.
Stupid law. The performer can simply not do what they don't wish, in the safety and comfort of their own home. Nothing anyone can do about it. It doesn't get much safer than this.
That seems like a reasonable law.
That depends on whether you believe that a ban leads to an overall reduction of such problematic imbalances, rather than just shifting shifting the whole industry into illegal markets that are unregulated and hidden, where they might actually get amplified. By banning it you are also giving up your opportunity to regulate.
Prostitution presents a similar dilemma, which countries handle in various ways. Some ban it completely, others like sweden have the "nordic/swedish" model where only the buyer gets penalized, and in some contries like Germany it is legal (either with or without additional regulations in place). Based on a brief search i think it's still up for debate whether the nordic model has the desired effects, with the opaqure nature of illegal markets making it hard to properly study the subject.
Does it though?
I see.
Haaaave you met Baptists?
Sadly, the demo is broken :-(
I've just got the app from f-droid and withdrawn some KUDOS π someone wants to try exchanging them via link/QR?
Let me know how it goes Magnus
It must be about ten years that Taler has stood unopposed as a proposed system for digital payments that's pretty good and might actually happen. It's not perfect, but it's better than anything else that exists. It's been a lot of years of tests, audits, experiments, and demos that occasionally turn up in my news feed β it was beginning to look like vapourware. I guess it'll be another several years before it gets to my part of the world, but it's good to see it finally getting started.
There are couple multi-billion euro companies (all the Payment Service Processors, Visa, Mastercard, etc) that would necessarily become several million euro companies if Taler was successful though. That's a lot of concentrated power that doesn't want Taler to succeed.
There's something I'm really struggling to understand when talking about things like Taler, and the "Digital euro" idea which has come up recently as well: What is it actually doing that's new?
Money is distributed digitally already. When you get a paycheck, no-one is actually moving physical paper and metal cash from a business account bank vault to a customer account bank vault, it's just numbers in a spreadsheet. So what's actually new when we're talking about digital currency like this post?
There must be something I'm missing here.
Taler provides digital cash as in anonymous transactions for the buyer. Neither the bank nor the state knows who you pay or for what.
However, the merchant can't hide that they are making money, thus enabling taxation and prevention of money laundering. That way it's even better than cash.
It's not based on blockchains and proof of work and thus doesn't have the ridiculous energy waste problems.
It's really quite good.
A lot of good replies here, but one thing that Taler doesn't do and credit cards do is...credit. This can be solved by having a line of credit at your bank and using Taler over that, which may actually be cheaper, as well.
As a non-European, I hope this spreads.
Current Platforms are private businesses. Paypal, Mastercard, Visa, they're all private businesses that can do whatever they want. This means that 1 They all charge a lot of money (I think 1-5% of the purchase) 2.1 since they're all american the new FΓΌhrer can turn off digital payments for a Business or even an entire Country he doesn't like. And the way he uses every single leverage he can get to get others agree to his terms, this seems realistic. 2.2 since they're private businesses with a quasi-monopoly on digital payments, they can threaten our economies if we try to do something they don't like, say raising taxes on them or limiting how much they can charge. A Taler by the national bank would be completely sovereign and make us independent from the US and its companies.
The Taler also has the advantage that the buyer is anonymous. So if you want to buy a Dildo without the seller, the bank, the government or even your family knowing, you can. If you delete the payment from your history then there is no proof at all that that payment came from you (well, your shipping address is on the package, but that's not something the Taler can solve lol). However, different from other crypto currencies, the seller is NOT anonymous, which prevents tax evasion.
Hope that cleared it up?
Yes, this helps, thanks.
I already understood the need to avoid private money agents like Paypal, visa, etc. In the UK we have the BACS and FPS systems that allow for direct free money transfer. Though they should be more usable for day to day transactions, they work well enough if you need to send a significant amount of money between bank accounts.
Your explanation of the anonymity seems like the real value add of these digital currencies. The fact this only applies to the buyer and not the seller is a good choice, and definitely wins over blockchain crypto. Looking at it more closely, the fact they use signed tokens rather than proof-of-x is also a very good choice.
I will need to read up on Taler's docs more closely. But looking at the summary of features on their site something hits me as an immediate problem - you need to "load up" a wallet. If Jane Doe wants to buy a coffee, it's far easier to just use a bank card (which may interface through a private money agent like visa, or a middleman like google/apple). Loading up private wallets isn't a difficult concept (it's how gift cards work), but it does add extra steps of friction that I think will need to be removed before this can really be taken up by the general public.
It may harm the anonymity aspect, but I think that to get people using it a system that could operate like a tap-once-and-done bank card payment, loading up a wallet for immediate spend seems like the best solution. It would also help alleviate any fears that typically are associated with blockchain based digital currency - primarily of losing the signed digital money as it sits in a wallet out with the bank account's protections. And once the system is normalised and people are used to it, then all the architecture is there for anyone that really needs the anonymity.
an additional note: part of why is it not perfect is that you can't send money privately to another person, like you would do with cash. in transactions like that there is a 3rd party involved that overses the transaction
Solving tax evasion while keeping both parties anonymous would be incredibly hard if not outright impossible though. Cash is king for privacy but also for tax evasion.
I donβt think any digital solution could or should replace cash. They can and should exist and function together.

Two of the things that I think are new vs the current system are:
Wallet: anonymous holding of currency without a custodian. You can't hold fiat currency digitally today without a bank or other entity providing that service.
Transfer: moving fiat currency anonymously and under your own direction without intermediaries. You can't make a digital payment or transfer in pure fiat currency today without that custodian providing the service (often through fee-based payment network). As a result, your identity is known when that transaction happens.
This.
A legit offline digital currency transfer akin to how one uses cash.
And ofc a giant body regulating it with proper audits, directives, delegated acts, etc.
Additionally this opens up the possibility of a modern personal existence without banks (ie private companies). We are now basically forced to use banks + (USA) monies transfer systems.
Disclaimer: Not an expert on this.
It was previously not really possible to send money digitally directly, except in the form of cyptocurrency. It always goes through banks or intermediaries. If you transfer money between bank accounts, the banks have to talk to each other to do so, and the "real" transfer happens between their central bank accounts at a later point in time. There is indeed only spreadsheets with numbers going up and down. Effectively the banks are in control of all of it. In most cases we don't want a slow bank transfer but some sort of user-friendly payment portal like PayPal or wero, which the banks also need to have contracts with (or, operate themselves).
My vague understanding here is that this process is completely detached from banks, and that you are thus transferring actual money. It's not just numbers in a spreadsheet going up and down.
If anybody understands it better please correct anything I got wrong.

That's kinda cool news. Hope it grows to be an alternative to these american systems.

Not sure what this means but European alternatives to us American megacorps are usually good.
Did you mean the European central bank in Frankfurt? Because I don't think Europe has a national bank, not yet being a nation and all that.
