# Eclipse Attacks ⎊ Definition **Published:** 2026-04-01 **Author:** Greeks.live **Categories:** Definition --- ## Eclipse Attacks An eclipse attack is a type of cyber attack where an adversary isolates a specific node from the rest of the peer-to-peer network. By monopolizing all incoming and outgoing connections to the target node, the attacker can feed it false information or prevent it from seeing the true state of the blockchain. This allows the attacker to trick the node into accepting invalid transactions or confirming double-spends. Eclipse attacks are particularly dangerous because they can be used as a precursor to more severe attacks, such as selfish mining or transaction censorship. Defending against these attacks involves diversifying node peer selection and implementing strict connection management policies. - [Call Depth Attacks](https://term.greeks.live/definition/call-depth-attacks/) - [Supply Chain Attacks](https://term.greeks.live/definition/supply-chain-attacks/) - [Network Partitioning](https://term.greeks.live/definition/network-partitioning/) - [Sybil Attacks on Oracles](https://term.greeks.live/definition/sybil-attacks-on-oracles/) - [Consensus Security Costs](https://term.greeks.live/definition/consensus-security-costs/) - [Risk-Adjusted Alpha](https://term.greeks.live/definition/risk-adjusted-alpha/) - [Transaction Censorship](https://term.greeks.live/definition/transaction-censorship/) - [Valuation Oracles](https://term.greeks.live/definition/valuation-oracles/) ## Glossary ### [Financial Loss Mitigation](https://term.greeks.live/area/financial-loss-mitigation/) Strategy ⎊ Financial loss mitigation within cryptocurrency derivatives functions as a systematic approach to minimizing capital exposure during periods of high volatility or adverse market movement. ### [Peer Review Mechanisms](https://term.greeks.live/area/peer-review-mechanisms/) Mechanism ⎊ Peer review mechanisms, within the context of cryptocurrency, options trading, and financial derivatives, represent a layered system of validation and scrutiny designed to enhance market integrity and reduce systemic risk. ### [Financial Derivatives Regulation](https://term.greeks.live/area/financial-derivatives-regulation/) Regulation ⎊ Financial derivatives regulation, within the context of cryptocurrency, options trading, and broader financial derivatives, establishes a framework for mitigating systemic risk and ensuring market integrity. ### [Peer Connection Control](https://term.greeks.live/area/peer-connection-control/) Control ⎊ Peer Connection Control, within the context of cryptocurrency, options trading, and financial derivatives, fundamentally concerns the mechanisms governing direct, decentralized communication channels between participants. ### [Diverse Peer Connections](https://term.greeks.live/area/diverse-peer-connections/) Interaction ⎊ Diverse peer connections represent the distributed network architecture where market participants exchange liquidity and pricing data without reliance on centralized intermediaries. ### [Cryptographic Data Verification](https://term.greeks.live/area/cryptographic-data-verification/) Data ⎊ Cryptographic data verification, within the context of cryptocurrency, options trading, and financial derivatives, fundamentally establishes the integrity of information exchanged across distributed ledgers and complex financial instruments. ### [Network Security Protocols](https://term.greeks.live/area/network-security-protocols/) Cryptography ⎊ Network security protocols within cryptocurrency rely heavily on cryptographic primitives, ensuring data integrity and confidentiality during transactions and smart contract execution. ### [Advanced Protocol Defenses](https://term.greeks.live/area/advanced-protocol-defenses/) Architecture ⎊ Advanced Protocol Defenses, within cryptocurrency, options, and derivatives, necessitate a layered architectural approach. ### [Protocol Level Security](https://term.greeks.live/area/protocol-level-security/) Architecture ⎊ Protocol Level Security, within decentralized systems, represents the foundational design choices impacting system resilience against malicious actors and operational failures. ### [Adversarial Network Behavior](https://term.greeks.live/area/adversarial-network-behavior/) Algorithm ⎊ Adversarial Network Behavior, within cryptocurrency and derivatives, manifests as strategically designed code intended to exploit vulnerabilities in market mechanisms or trading protocols. ## Discover More ### [Resource Consumption Quotas](https://term.greeks.live/definition/resource-consumption-quotas/) ![A conceptual model visualizing the intricate architecture of a decentralized options trading protocol.
