To ensure Casper is safeguarded from potential misuse, it's important to address vulnerabilities associated with blockchain software gossip. Specifically, there needs to be robust mechanisms to prevent the propagation of fake IP addresses among nodes, which was notably exploited during the attack on Solana.
Background:
During the Solana attack, malicious actors gossiped fake IP addresses, causing nodes to attempt peering with these false addresses.
The attack predominantly involved IP addresses of major banks which led to significant complaints from these corporations.
As a result, provider had to take severe measures, including removing Solana validators from their facilities.
Problem:
Similar attacks can be replicated on other blockchain platforms, possibly on Casper, posing a risk.
Proposed Solution:
- Check if similar attack can be performed on Casper Network
- Check if any mechanism preventing such behavior are present
- If there aren't any - propose a solution (detect/filter out fake IP addresses, implement rate limiting or similar)
