Team Ethereum 2.0 approved the proposed method, but mechanism of secret selection of the block producer everything yet is an area active research. Thus, we are awaiting additional information regarding of this mechanism with the transition of Ethereum 2.0 to the first and second phases of development “, – writes company.
In the peer-to-peer mechanism exchange messages It was identified three potential attack vectors. it concerns, for example, opportunities spam attacks: “We have identified a problem when a malicious node can send unlimited messages from more old blocks of the rest of the network with minimal punishment, which allows it to harm networks and restrict legitimate messages “.
