# Post Commitment Alteration ⎊ Area ⎊ Greeks.live --- ## What is the Alteration of Post Commitment Alteration? Post Commitment Alteration refers to the illicit act of modifying a value or action after it has been cryptographically committed using a commitment scheme. This constitutes a breach of the scheme's binding property, where the committer attempts to reveal a different value than what was originally committed. Such alteration undermines the integrity of the protocol and can lead to unfair outcomes or financial fraud. It represents a direct attack on the trustless nature of cryptographic commitments. This manipulation is a significant security concern. ## What is the Prevention of Post Commitment Alteration? Prevention of post-commitment alteration relies on the strong binding property of cryptographic commitment schemes. This property is typically enforced by the collision resistance of the underlying hash function or the mathematical properties of the chosen cryptographic primitive. It must be computationally infeasible for a committer to find an alternative value and corresponding nonce that would produce the same initial commitment. Robust protocol design, including adequate nonce entropy, is crucial for effective prevention. Immutable blockchain records further strengthen this. ## What is the Consequence of Post Commitment Alteration? The consequences of successful post-commitment alteration are severe, particularly in financial derivatives and cryptocurrency markets. In a decentralized auction, a bidder could change their bid after seeing others, leading to market manipulation and unfair price discovery. For options trading, it could allow a counterparty to renege on agreed-upon terms, resulting in financial losses for the other party. This breach erodes trust, introduces systemic risk, and can invalidate the entire purpose of a decentralized protocol. It jeopardizes the fairness and security of market operations. --- ## [Commitment Binding Property](https://term.greeks.live/definition/commitment-binding-property/) The guarantee that a committed value cannot be altered after the initial lock. ⎊ Definition ##
