I am planning to make an website / wordpress plugin. Site will ask visitor's account id.
Site will show content only if a bitcoin transaction with specified account id & bitcoin amount & message exist.
My big plan let visitor to track how a software have been made. Like in a version control system, like in Github visitor could track changes. But!! certain changes / commits the developer could charge some dollar.
My specific question is: Can I query all the bitcoin transactions back to the past and filter with a predicate contains the following fields: account id = 'abc' & bitcoin amount = 123 & message = 'def'?
