Let's adopt patio11's criteria to a programmable public blockchain, like ethereum - Customer UX: crypto wallets built into browsers and phones. Connect your wallet to any webpage to pay. Or, tap your phone to pay via a crypto payment - Certainty: crypto transactions are, by default, instant and irreversible. Any kind of chargeback scheme, refund policy, or time-delay may be built into the crypto app layer - Settlemen…
- Settlement/Certainty time: Blockchains combine these into one. They depends heavily on the specific chain. For some networks, its basically instant. Eth seems to be around a minute or so. Bitcoin is around 60 minutes.
- Reversibility: Agreed, although whether this is good or bad depends on the user.
I like the way it was said in the article, these are all axes of comparison. Consumers choose products based on a set of criteria. For many, irreversibility or the risk of loosing everything due to a lost wallet is a dealbreaker, even if transfers may be much faster than other methods.
