It's basicially david chaum's blind-signature money idea. It's centralized but the central issuer can't connect the outputs to the inputs. (but unique inputs signed by the issuer correspond to unique outputs)
>Also are transactions final and irreversible?
I think so unless you are able to reveal the secrets of the transaction. Hmm, however revealing the secret to someone is basicially same as spending it to them (analgous to releasing a signed and finalized transaction into the mempool in cryptocurrency). It's finalized by the issuer signing it.
Like you basicially send the vendor the secret, and then they hand it in to the coin issuer and wait for the issuer to sign a new input, before giving you the merchandise. So idk how it would work reversing the transactions

It will be choked out at key junctions with KYC in the same way crypto has.

The claims that is is privacy preserving are deceptive, and in my option constitute an act of intentional fraud on the part of its creators -- the fact that people are deceived by the privacy claims is clear in your comment: You ask why would the banks adopt something private. The answer is: it isn't.
Its existence is justified under a fairytale model of how the world works-- a false belief that actually anonymous payments are unlawful and that their compromised alternative is the best possible. In the path of doing so, they not only falsely sell a system with compromised privacy as private, but they also help bring about a dystopia where privacy is unlawful in much the same manner that doing business with companies that refuse to accept cash does.
It would be fair to say that its an upgrade to privacyless systems-- because it doesn't attach the sender's identity to the transactions themselves--, but to characterize it as a private or privacy preserving system is a lie.

I find this objectionable, but not at all deceptive or manipulative.

People hear that it's private and -- unsurprisingly-- think it's private! :P In my view it's like to Apple's proposed content scanning in end to end encryption that applies a lot of additional cryptographic complexity with language that suggests that it's protecting the user's privacy, but in reality the complexity is entirely there to undermine their privacy (in a somewhat selective way) and a far simpler scheme would give much stronger privacy.
I think it's analogous to promoting a key-escrow cryptosystem as "communicate privately!"-- both in terms of people not getting the privacy from it they would expect and helping to bring about a world where actual privacy is unlawful. The privacy problems of Taler are essentially identical to those of key-escrow: even if you don't have any fear of 'lawful' access, any access that exists may be abused. The only reliable solution to the security/privacy problems is for the access to not exist unless that is literally impossible. But it's clearly not impossible, as many people use more private systems than taler every day including in Germany.
Taler is strictly less private and considerably more complicated than a basic chaum-cash token system-- which actually provides the privacy people expect it to have. So it's not like I'm suggesting blockchain mumbo-jumbo is the only alternative. :)

The wording on the Taler website is a bit wishy-washy, but I THINK the TL;DR is:
1. They tried to do be a payments processor with assistance from a German bank.
2. That didn't work out for what Taler claims are "unrelated reasons" but I suspect we all can agree it was due to KYC/AML hurdles.
3. The Taler plan now appears to not be a payments processor but rather merely an issuer.
And in that respect, there is plenty of precedent for that passing in the EU, i.e. there are are already many online places you can go swap your Euro for Bitcoin legally.
So, yes, there will still be KYC/AML. You will still need to provide your ID to swap your Euro for your Taler. But after that, Taler has nothing to do with transaction processing, you go spend your Taler balance elsewhere and somebody else's server processes the transaction. Taler will know and be obligated to retain records of who bought how much, when and how but not when and where (of if) they spent it.
At least that's my interpretation of the word-soup on their website.

If I am understanding Taler, it is not like cash coins/paper where the government does not and has no way to know that you, e.g., bought a bottle of wine from a vintner with cash, and that vintner can use that bill/coins in many different ways and the gov't has essentially no way to trace or track that.
The way I am seeing it... please correct me where I'm not understanding something... the Taler architecture would require you to pay cash into an exchange, then you extract (likely IDs/tagged/marked) Taler, you then pay that Taler to a merchant, e.g., who by policy cannot remain anonymous, and that merchant deposits that market Taler into the exchange. So in that scenario, what has happened is that the Taler the merchant received "privately" is clearly associated with the Taler you extracted from the exchange to pay the Taler deposited by the Vintner.
It's maybe private in that the Vintner does not need to know who you are, but you can bet the control freak tyrants in the government will know that you bought that wine.
So what you may say, wine is fine, but what if it's something the government doesn't want you doing, buying, supporting? Maybe wine is now illegal because {fill in the reason}, maybe you are not sufficiently obedient and compliant during an "emergency" and need to be cut off? Maybe you are sanctioned by the EU and all your money is taken and you have no means of even feeding yourself other than the "humanitarian" limit of living on €200/month and you can't even return to your native Switzerland from Brussels because you are not allowed on trains, planes, or allowed to drive across borders like happened to Jaques Baud for speech some tyrannical EU politician or bureaucrat did not like?

I have no idea how that's supposed to work.

I agree, there is absolutely zero chance that especially the tyrannical government of the EU, which requires total control for the next phases of its very existence, will not fight with any and every dirty trick it can to arrest total control over spending/money.
Where and how people spend money is almost more valuable than communications information and other relationships. Money is intentional, it is committed. You can say all kinds of things in chat, and the European tyrants are already using that to imprison people and are working even harder to simply punish you without even charges, but money changing hands clearly demonstrates far more than just words.
Unfortunately for Europe, if it had only been able to hold on for the last 25 or so years on their own currencies, this kind of payment processing network that is actually anonymous could have fully replaced and made the Europe totally irrelevant and useless by simply making I possible to make a payment in one currency and it arrive instantaneously in another currency. You could have paid for things anonymously just like you could when you had paper and coins, a transaction between you and a product/service provider. The future will be far bleaker in a way that I don't think we can even imagine since there is not a single comparable thing that has existed or happened in all of human history that is remotely similar, losing total anonymity that all the worst dictators, tyrants, and maniacs of all of human history could not have collectively even dreamt of... now in the hands of the illegitimate, and unelected EU Commission and its apparatchiks.

When people start saying hyper-opinionated stuff like this, I usually tune out. The rest of your comment, whether or not it has nuggets of merit or insight, is going to be tainted by the fact that you've bought into the whole "evil EU is tyrannical" thing. It's very in vogue right now among the MAGA and alt-right types. They all started hating the EU with a passion of a thousand suns all of a sudden, pretty much in synchrony, and curiously coinciding with anti-EU propaganda campaigns driven by EU's fascist neighbour next door, angry at the EU stopping it from genociding its way through eastern Europe.
Like, your point about one of the Euro's main raison d'etres for the general public - frictionless cross-border transactions without needing to convert currencies - going away with online payments, that's a good point. Too bad about all the talking points you couched it in.

> The NGI TALER project is funded under Horizon Europe (Pilots for the Next Generation Internet) with the aim of bringing GNU Taler to market across Europe. https://www.taler.net/en/ngi-taler.html
Unlike crypto, it is designed from the beginning with KYC/AML in mind. https://www.taler.net/en/principles.html
The issue seems to have been that GLS Bank was not able to support this beyond Germany. KYC/AML is a pretty complex topic. And since GLS is a tiny local bank (1,100 employees) it would have been a very large project for them. https://ich.taler.net/t/taler-en-belgique-en-france-ou-au-lu... https://www.gls.de/taler
More on the implemtation here: https://www.taler.net/en/kyc.html https://docs.taler.net/design-documents/023-taler-kyc.html https://docs.taler.net/taler-kyc-manual.html

Blockchains that support stablecoins are already here and millions of people already use them (and soon agents will use them as well).
All for worldwide, instant and extremely low fee payments and transfers.

That's just not true, and I'm not talking about "you can pay with Bitcoin in the store" use case but the stable coin use case for settlement, which you can see Stripe expand a lot in the past years.
