You can't, but the model is different.
If Bitcoin transactions involved giving your private key to every entity you wanted to transact with (like how credit card numbers work), then this would be a problem.
- emodendroket 3y agoI don't think that really solves the problem... for instance, you can get your money back if the vendor does not render the product or service promised (with some restrictions of course). With Bitcoin, you're on your own.
- PretzelPirate 3y agoWith something like Ethereum, you can build refunds into your payment model as long as you and the merchant agree on a set of trusted 3rd parties who can handle any disputes. You can choose different trusted mediators for each transaction and can decide the rules (ex: how many of them are needed to decide that a refund has to happen). You can also choose not to trust any 3rd party. If I'm buying an on-chain digital item, I probably don't need to support disputes, but if I'm buying something off-chain and don't trust the merchant, I might want that protection.
