# 51 Percent Attack ⎊ Area ⎊ Greeks.live --- ## What is the Mechanism of 51 Percent Attack? A 51 percent attack occurs when a single entity or colluding group gains control over a majority of a cryptocurrency network's hashing power or stake. By commanding this computational or financial weight, the actor gains the ability to disrupt the recording of new transactions and prevent confirmation of blocks. This dominance permits the potential reversal of previous transactions, which introduces the critical risk of double-spending within the ledger. ## What is the Vulnerability of 51 Percent Attack? Proof-of-work and proof-of-stake systems rely on decentralized participation to maintain the integrity of their consensus protocols. If an adversary secures excessive influence, the network loses its fundamental promise of immutability and trustless validation. Market participants holding derivatives or crypto-assets face immediate liquidity impairment and potential price dislocation when such systemic integrity fails. ## What is the Consequence of 51 Percent Attack? Institutional traders and quantitative analysts monitor chain security metrics because a successful breach invalidates the underlying data integrity required for derivative pricing models. Financial loss stems from the inability to finalize trades or the sudden devaluation of collateralized positions following a consensus compromise. Markets respond to these technical failures through rapid volatility spikes, forced liquidations, and a long-term erosion of asset credibility. --- ## [Reorganization Risk](https://term.greeks.live/definition/reorganization-risk/) The possibility that previously confirmed blocks are invalidated due to the emergence of a competing chain branch. ⎊ Definition ##
