uzair Posted August 21, 2018 Report Share Posted August 21, 2018 As we know each blockchain transaction has inputs and outputsIf all transaction inputs are spent then these inputs doest not contain important information anymore as it will not participate in any future transactionsAnd we can find blocks that consists of such transactions only and we can remove all this data preserving only block hash So this means that a blockchain will not grow forever , it will grow forward but closer to the begining blocks can be replaced by its empty placeholdersGoing this way we, of cause, lose transactions history but integrity would be ok Link to comment Share on other sites More sharing options...
