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
Don't worry, no question is silly or idiotic
The blockchain is a public ledger that anybody can have. So when you say 'who created the blockchain?' You probably misunderstand. For example, the people that own blockchain.info created their blockchain etc!
And since the blockchain is a public ledger, and anybody can have a copy etc, it would be funny to charge commissions to use the blockchain!
Miners get commissions though, because they put in a lot of work to validate blocks and make sure the transactions added are legit.
