…ize函数,将再次给header.Time赋值,使得state状态不一样,从而产生分叉.模拟重现,部署智能合约,合约中调用now()函数给变量赋值,由于now()函数取值为header.Time值,使得打包块打包的header.Time值与验证时header.Time值不一样,从事验证时stateRoot验证不通过,产生bad block从而分叉. 2. 指针赋值发生浅拷贝.

给header.Time赋值时如果在Finalize函数中,在收到远端挖出的块的时候,会在验证state的时候也会再次调用Finalize函数,将再次给header.Time赋值,使得state状态不一样,从而产生分叉.模拟重现,部署智能合约,合约中调用now()函数给变量赋值,由于now()函数取值为header.Time值,使得打包块打包的header.Time值与验证时header.Time值不一样,从事验证时stateRoot验证不通过,产生bad block从而分叉.
