I haven't looked at Taler in a while. What capabilities do they have to transfer money around without being surveilled? Also are transactions final and irreversible?

>What capabilities do they have to transfer money around without being surveilled?

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

I thought it looked an awful lot like David Chaum's DigiCash. If they haven't brought Chaum into the discussion, I would be very nervous about using Taler.

[edit] Yes, he has been involved. https://www.heise.de/en/news/39C3-How-the-open-source-cash-G...

This is a proposal to operate a regulated payments processor, supervised by BaFin. All the usual, necessary regulations and consumer protections will apply under German law.

The announcement claims a "privacy-preserving [...] payment system". Are you saying this would come in conflict with German law?

Taler is privacy-preserving for the payer, but not for the payee. This solves many legal issues such as tax evasion and money laundering.

I think it is the European sense of privacy where the government is implicitly inside everyone's trust circle.

I think Taler is designed to be privacy-preserving while being able to comply with national laws. So not the currency you're looking for if you wanna buy something illegal.

Nor something that you want to remain private.
