if a bitcoin transaction using a username might be a lot cooler too, I might be able to think positively in this way the transaction would seem to be great if some coinabse users often make small amounts of transactions using bitcoin, so it doesn't pile up on the bitcoin transaction network, but I say before this it still didn't look great if it was done only for coinbase users
he has been fighting for this patent since 2015, so it's natural that many use something similar every year. If coinbase wins this patent, it means that all other services can still use it, but by following the fixed rules of coinbase.
I still think this is no different from the branch address system, but I don't know the details. What is clear is this feature will benefit users even though they can no longer avoid KYC etc.
I didn't know he was on it since 2015. If he was the first to have introduced the concept then he deserves the patent. Congrats to Brian Amstrong.
Its just surprising to see how many developers today have created innovations that weren't really patented in the name of opensource. Now that he got it patented then this will just be for Coinbase alone and they can sue which project uses it. I can really think of paypal when making transactions base on our email ID.
