Initial performance in the technical part: - Throughput: 1000 transactions payment per second - Latency: 10-second for validating a payment

10 seconds sounds longer than current credit card payments? I could imagine that to be a barrier in some situations.

This will be the base layer. They expect custodial wallets and payment channels on top (in Bitcoin terms exchange wallets and lightning network).

See the Libra blockchain paper, section 8:

> We anticipate that many payment transactions will occur off-chain, for example, within a custodial wallet or by using payment channels [45]
