sorry for my idiotic quexsstion but who created it? bitcoin? if so why companys cann use blockhain for their needs e.g. ibm and other companys shoudnt they pay a commision to have the right to use the blockhain
Satoshi Nakamoto dissapeared after he created Bitcoin and did not file patents on his technology. It is now public domain and for that reason nobody needs to pay anything to use it. Nothing is stopping these companies from
trying to patent many parts of the technology.
I think PayPal are trying to patent the virtual wallet part of it, and if successful other companies would have to pay them to host virtual wallet services. The chances of them being successful, with all other companies being in the same scene long before them, will make things very difficult.
