# Eclipse Attack ⎊ Definition **Published:** 2026-03-13 **Author:** Greeks.live **Categories:** Definition --- ## 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. - [Sandwich Attack Mechanics](https://term.greeks.live/definition/sandwich-attack-mechanics/) - [Electromagnetic Analysis](https://term.greeks.live/definition/electromagnetic-analysis/) - [Latency Sensitivity](https://term.greeks.live/definition/latency-sensitivity/) - [Man-in-the-Middle Attack](https://term.greeks.live/definition/man-in-the-middle-attack/) - [Network Partitioning](https://term.greeks.live/definition/network-partitioning/) - [Governance Attack Mitigation](https://term.greeks.live/definition/governance-attack-mitigation/) - [Reentrancy Attack Mechanism](https://term.greeks.live/definition/reentrancy-attack-mechanism/) - [Reentrancy Attack Prevention](https://term.greeks.live/definition/reentrancy-attack-prevention/) ## Glossary ### [Network Traffic Analysis](https://term.greeks.live/area/network-traffic-analysis/) Analysis ⎊ Network Traffic Analysis, within cryptocurrency, options, and derivatives, focuses on dissecting communication patterns to identify anomalous activity and potential market manipulation. ### [Network Surveillance](https://term.greeks.live/area/network-surveillance/) Analysis ⎊ Network surveillance, within cryptocurrency, options, and derivatives, represents a systematic evaluation of on-chain and off-chain data to identify anomalous trading patterns and potential market manipulation. ### [Network Segmentation](https://term.greeks.live/area/network-segmentation/) Architecture ⎊ Network segmentation, within the context of cryptocurrency, options trading, and financial derivatives, fundamentally involves partitioning a network into isolated segments to enhance security and operational efficiency. ### [Protocol Hardening](https://term.greeks.live/area/protocol-hardening/) Architecture ⎊ Protocol hardening, within decentralized systems, represents a multifaceted approach to fortifying the underlying infrastructure against potential vulnerabilities. ### [Distributed System Security](https://term.greeks.live/area/distributed-system-security/) Architecture ⎊ Distributed system security, within the context of cryptocurrency, options trading, and financial derivatives, fundamentally hinges on the layered design and interdependencies of the underlying infrastructure. ### [Double Spending Attacks](https://term.greeks.live/area/double-spending-attacks/) Threat ⎊ A double spending attack is a malicious act where an attacker successfully spends the same cryptocurrency funds more than once. ### [Malicious Node Behavior](https://term.greeks.live/area/malicious-node-behavior/) Action ⎊ Malicious node behavior manifests as deliberate deviations from protocol rules, often involving transaction manipulation or consensus disruption. ### [Security Incident Response](https://term.greeks.live/area/security-incident-response/) Action ⎊ Security incident response within cryptocurrency, options trading, and financial derivatives necessitates swift, decisive action to contain and mitigate potential losses stemming from unauthorized access, manipulation, or system failures. ### [Peer Connection Management](https://term.greeks.live/area/peer-connection-management/) Algorithm ⎊ Peer Connection Management, within cryptocurrency and derivatives, represents a systematic approach to establishing and maintaining reliable communication channels between trading nodes and market participants. ### [Node Synchronization Issues](https://term.greeks.live/area/node-synchronization-issues/) Algorithm ⎊ Node synchronization issues, within distributed ledger technology, represent discrepancies in the state of the blockchain across different nodes participating in the network. ## Discover More ### [Server Infrastructure Security](https://term.greeks.live/definition/server-infrastructure-security/) ![A precision-engineered mechanism featuring golden gears and robust shafts encased in a sleek dark blue shell with teal accents symbolizes the complex internal architecture of a decentralized options protocol.
