Hash Function Collision Attacks

Cryptology

Hash function collision attacks occur when an adversary identifies two distinct inputs that generate the identical output hash within a cryptographic algorithm. Such mathematical vulnerabilities undermine the immutability of distributed ledgers by enabling the substitution of fraudulent data within a verified block. In the context of derivatives, this exploit could theoretically allow a malicious actor to replace a smart contract execution instruction without detection, potentially leading to unauthorized settlements or distorted market pricing.
