Let me explain myself a bit
I am new around blockchain biz but not in tech. Somehow I missed the bus so far.
So what I gather is a transaction is sent out and whoever gets there first creates a recorded block for good to seal the transaction and this process can take anywhere from few seconds to 10 mins. Please correct me if I am wrong. I am mostly from web / app world so I am trying to figure out how such a delayed transaction recording mechanism be useful for say user authentication during a login process.
Am I missing something.
