code: func (b *BlockGen) AddUncheckedTx(tx *types.Transaction) {
  	b.txs = append(b.txs, tx)
  }
docs: // AddUncheckedTx forcefully adds a transaction to the block without any
  // validation.
  //
  // AddUncheckedTx will cause consensus failures when used during real
  // chain processing. This is best used in conjunction with raw block insertion.
