Sorry for not answering to your question directly, but why not just use subuids for separation instead?

podman run -d --restart unless-stopped \
  --uidmap "+0:@100001:1" \
  --name nginx-1 \
  --port 8081:80 \
  docker.io/library/nginx

podman run -d --restart unless-stopped \
  --uidmap "+0:@100002:1" \
  --name nginx-2 \
  --port 8082:80 \
  docker.io/library/nginx

From their site:

Taler does not introduce a new currency. Taler uses a digital wallet storing coins and payment service providers with settlement accounts in existing currencies. Thus, Taler’s cryptographic coins correspond to existing currencies, such as US Dollars, Euros or even Bitcoins.

Gnu taler is not a crypto. It needs to work with banks, and the transfers are made with normal currencies. It keeps the sellers info public but the customers private. It is quite neat in my opinion.

But it’s basically not used anywhere, so it is not a real payment option at this time.
