調(diào)試這個(gè)函數(shù)試試，看看是那個(gè)返回false

func?isValid(newBlcok?Block,?oldBlock?Block)?bool?{
???if?newBlcok.Index-1?!=?int64(oldBlock.Index)?{
??????return?false
???}
???if?newBlcok.PreBlockHash?!=?oldBlock.Hash?{
??????return?false
???}
???if?calculateHash(newBlcok)?!=?newBlcok.Hash?{
??????return?false
???}
???return?true
}

Block結(jié)構(gòu)體中的GenerateNewBlock函數(shù)中的hash必須等data賦值完之后再計(jì)算，順序換一下就可以了
