Namecoin, Pay with your name.

[steban]

Be using BIP70 and the /id namespace, a user could complete a payment by just entering their registered ID and confirming the transaction on their Namecoin wallet (be means of BIP70).

That way Namecoin becomes a pay with your name currency. No need for QR codes, NFC,... Crypto transactions become human meaningful and frictionless. The /id data could include shipping address, so no need to create an account or provide any other information. Just write your name, accept the transaction on your Namecoin wallet, and done.

It becomes something alike signing an invoice.

This would be cool. There was a discussion about it here: https://bitcointalk.org/index.php?topic ... msg3280758

tldr: Bitcoin devs did not want to support it back then

Thank you for the link, very interesting. The discussion talks about using Bitcoin in conjunction with Namecoin in a somehow similar system. The idea I described does not make use at all of Bitcoin.

Ultimately makes sense for Bitcoin Devs not wanting to support it, it changes Namecoin from a crypto that does key pair, into a system that also works as a currency; creating direct competition.

Namecoin becomes a "pay with your name crypto currency", which is an actual improvement over the current Bitcoin system.

This proposal would impact anonymity to some extent, right? If you're associating your currency transactions with an id/ name that you own, it becomes a lot easier to link transactions.

The same information is registered when you use your credit card. And Bitcoin does not provide much difference level of anonymity. Also some crypto payments in the future will probably requiere you to use a registered /ID

Sorry, but "it's not worse than a credit card" isn't a particularly convincing argument. Bitcoin transactions are linkable, but this takes effort, and can be prone to errors. If you link the transactions to an ID, you provide extra information that benefits people trying to link transactions. Engineering effort should be spent on reducing linkability, not increasing it.

I'm not clear on which payments you're referring to, but I would not support a business that demands identification from its customers.

@OP: Are you aware of sendtoname and sendtoalias?

In Namecoin things work the other way round: you send coins to a name.

This feature is still known too little yet it was implemented quite some time ago. It works from the command line and also the Qt GUI.
