Eclipse Attack Definition - Glossary

Eclipse Attack is a network attack isolating a node, manipulating its view of the blockchain by controlling its connections.

Eclipse Attack is a network security threat targeting blockchain nodes. It isolates a specific node by overwhelming its connections with malicious peers. This attack allows the perpetrator to control the node's view of the blockchain. Misleading it about the state of the network. The attacker can delay transactions, double-spend, or censor certain network activities. It's particularly effective in peer-to-peer networks where nodes rely on connected peers for information. Mitigating such attacks involves enhancing network diversity and implementing robust peer selection protocols. This ensures nodes maintain a reliable and authentic view of the blockchain.
