Every time bitcoin transfers Will check the transfer in and transfer out of the address ？？ It doesn't have to count hundreds every time G The data of ？？
Take the answer 1：
To be exact, bitcoin has no concept of balance , It should be a pile UTXO (Unspent Transaction Outputs, Unused transaction output ).
Bitcoin has a simple payment authentication thing , namely Simple Payment Verification, abbreviation SPV. You can see the blogger's ： Bitcoin block structure Merkle Tree and simple payment verification analysis .
stay SPV Node , Do not save all blockchain data , Do not download all transactions of the block , Save only block header data . The overall storage capacity requirements will be greatly reduced .
