示例1: validateTx
// validateTx checks whether a transaction is valid according
// to the consensus rules.
func (pool *TxPool) validateTx(tx *types.Transaction) error {
// Validate sender
var (
from common.Address
err error
)
// Drop transactions under our own minimal accepted gas price
if pool.minGasPrice.Cmp(tx.GasPrice()) > 0 {
return ErrCheap
}
// Validate the transaction sender and it's sig. Throw
// if the from fields is invalid.
if from, err = tx.From(); err != nil {
return ErrInvalidSender
}
// Make sure the account exist. Non existent accounts
// haven't got funds and well therefor never pass.
currentState, err := pool.currentState()
if err != nil {
return err
}
if !currentState.HasAccount(from) {
return ErrNonExistentAccount
}
// Last but not least check for nonce errors
if currentState.GetNonce(from) > tx.Nonce() {
return ErrNonce
}
// Check the transaction doesn't exceed the current
// block limit gas.
if pool.gasLimit().Cmp(tx.Gas()) < 0 {
return ErrGasLimit
}
// Transactions can't be negative. This may never happen
// using RLP decoded transactions but may occur if you create
// a transaction using the RPC for example.
if tx.Value().Cmp(common.Big0) < 0 {
return ErrNegativeValue
}
// Transactor should have enough funds to cover the costs
// cost == V + GP * GL
if currentState.GetBalance(from).Cmp(tx.Cost()) < 0 {
return ErrInsufficientFunds
}
// Should supply enough intrinsic gas
if tx.Gas().Cmp(IntrinsicGas(tx.Data())) < 0 {
return ErrIntrinsicGas
}
return nil
