An eclipse attack is a network-level attack in blockchain systems where a malicious actor isolates a target node, monopolizing its connections to control the information it receives and sends. This module will explore the mechanics, impacts, and preventive measures of eclipse attacks.
Q1: What is the primary goal of an eclipse attack in a blockchain network?
A1: To isolate a node and control its network view
Q2: How does an attacker typically initiate an eclipse attack?
A2: By flooding the target node with connections from malicious nodes
Q3: What distinguishes an eclipse attack from a Sybil attack?
A3: Eclipse attacks isolate a node; Sybil attacks involve creating fake identities
Q4: Which preventive measure can help protect against eclipse attacks?
A4: Connecting to a diverse set of randomly selected peers
