Eclipse Attack
An eclipse attack is a cyberattack where an adversary isolates a specific node from the rest of the network by controlling all of its peer connections. By controlling the information the node receives, the attacker can feed it false transaction history or prevent it from seeing the real network state.
This can be used to trick the node into accepting invalid transactions or double-spending coins. It is a significant risk for wallets and exchange nodes that do not verify their peers.
Defense involves implementing diverse peer selection algorithms and robust network monitoring. It targets the networking layer rather than the consensus algorithm.
