So could the developer's mistake/error/system test be duplicated a lot at a low cost?
Developers have the testnet availale to test and prevent those errors.
Is that what you asked or i understand it wrong?
I am asking if this is a way to attack the actual block chain at a low cost.
As I understand it the block mined was not valid. Some one managed to spend out of order Tx an and Tx b. So the block was rejected by the block chain.
I am asking could this be done more often and harm the blockchain.
As it is a pool lost a block with bad info in it.
so if the blockchain is flooded with this style of info more and more invalid blocks can appear.
So A can this be done at a high rate killing off lots of blocks found as invalid?
and B is it cheap to do it?
Has someone stumbled of a way to make an invalid block and are they super rare.
