示例1: chkblock

er = errors.New("CheckBlock() : block timestamp too far in the future")
return
}
if prv, pres := MemBlockChain.BlockIndex[bl.Hash.BIdx()]; pres {
if prv.Parent == nil {
// This is genesis block
er = errors.New("Genesis")
return
} else {
return
}
}
prevblk, ok := MemBlockChain.BlockIndex[btc.NewUint256(bl.ParentHash()).BIdx()]
if !ok {
er = errors.New("CheckBlock: " + bl.Hash.String() + " parent not found")

// Check proof of work
