Wow, see now that's awesome! Thanks for sharing! And yeah, it would be beneficial to not have a third party system that uses lets say visa. Hopefully more development will take place on this card. Any ETA on it's release date?
its a gimick, its not solving anything. these days everyone has a phone and a phone app can easily sign a tx 'offline' and push a signed tx to the internet..
its not solving bitcoin congestion of mass adoption.
plus also requiring multiple hubs eg 1 per town.. what financial benefit would anyone have to be a hub(full node)...
Well I guess I get what your saying. I just like the concept of the card in general though that uses a lot of security measures when someone tries to buy something with the card. But I see in multiple threads where people want a quicker side chain for faster micro transactions, why not just stick to the original Bitcoin protocol, use Bitcoin as assets, and allow visa to work as the Lightning network? I know they charge small fees, but there are bigger problems to face when the devs change the whole structure of bitcoins block chain in general.
Do you have a suggestion on how to fix this problem? I'm just more interested in how to attract local businesses to think about accepting Bitcoin, and the fact of the tx limit is not a very good selling point to any body.
"side chains" are just glamourised altcoins.. but as you 'hinted' visa could invent their own altcoin... seeing as many financial industry businesses are already looking into blockchain technology.. its a very big possibility that some of the "sidechains", i mean altcoins will be visa/mastercard operated..
i also think that bitcoin will be a fortknox type reserve asset currency like what gold use to be rather than a transaction ledger for average joe. where each bank branch/business transacts
offchain for customers. and then makes a batched payment compiling together all offchain payments into one single
bitcoin transaction to represent movements from one service/country to another. (if bitcoin covers more than 3% world population usage)
swap
offchain for bank notes and
bitcoin for gold and you will understand my analogy to fortknox.
but at the end of the day. it will be these altcoins that banks hold for businesses, pay to staff and then tax to governments that people will end up using and bitcoin will fade into the background. only to be used/touched by the rich and powerful
also lightning network is just a buffer, its more about speedy transactions, and not about tx data reduction. once things are finally 'settled' / confirmed to the blockchain after channels are closed.
