<\/a>What is an Eclipse Attack?<\/strong><\/h2>\n\n\n\n

An Eclipse Attack in blockchain technology is a network attack where a malicious actor isolates a target node within a blockchain network. By controlling or overwhelming the peer connections of this node<\/a>, the attacker ensures that all communication to and from the node passes through their controlled nodes.<\/p>\n\n\n\n

This isolation allows the attacker to manipulate the victim’s view of the blockchain network<\/a>, potentially feeding them false data or preventing them from receiving honest transactions.<\/p>\n\n\n\n

<\/a>Consequences and Prevention of Eclipse Attacks<\/strong><\/h2>\n\n\n\n

In decentralized systems like blockchain, nodes rely on peer-to-peer communication to maintain network integrity. An eclipse attack can disrupt consensus<\/a>, double-spend transactions, or even set the stage for more complex attacks, such as 51% attacks.<\/p>\n\n\n\n

Preventing such attacks involves ensuring diversity in peer connections, randomizing peer selection, and implementing stable network layer defenses. These measures help maintain the decentralized nature and security of blockchain networks against such vulnerabilities.<\/p>\n\n\n\n

An Eclipse Attack is a cyberattack on a blockchain where an attacker cuts off a node from the rest of the network, controlling what the node sees and communicates. This manipulation can lead to various issues, such as misleading the node about the state of the blockchain or enabling further attacks. <\/p>\n","protected":false},"featured_media":0,"template":"","glossary_letter":[304],"glossary_term":[288,281],"class_list":["post-7509","glossary","type-glossary","status-publish","hentry"],"acf":[],"yoast_head":"\nWhat is Eclipse Attack in Crypto?
