Bitcoin's block size is 1mb? I know 1mb is starting size of 2009 year.
Then how much is current status?
And it requires Hardfork? or Softfork?
Because of that 1mb size, Transactions capacity bitcoin can deal is limited? 7 transactions per 1 second? Is this right?
Not sure if you are trying to mess up or not. Just give me a reference of your findings then may be you will find me interested to answer your questions. Good luck
