RE: Response to Cosmos white paper's claims on DPOS security

in #steem4 years ago (edited)

Hi Dan. This is really interesting. I'm wondering - is it possible for the block producers to collude and produce a block with a fake transaction, and then proceed to produce subsequent blocks that confirm the one with the fake transaction, until 2/3 of them have validated it?

It sounds like what you are saying is that the network of validators would know / catch this, but how would they know that the fake transaction was fake?

Sort:  

because it wasn't properly signed and/or it violated the constraints defined by code.

All transactions are digitally signed. You can't create a valid transaction without the keys to sign it. All block validators can easily verify the transaction.
