Expert Warns of Potential Vulnerability in Lightning Network Due to Quantum Computing

Udi Wertheimer has raised concerns about the structural vulnerability of the Lightning Network in the event that a cryptographically relevant quantum computer becomes capable of deriving private keys from public keys. According to NS3.AI, Wertheimer highlighted that the design of the Lightning Network necessitates the sharing of public keys and depends on third-party storage structures. This reliance could increase the risk of theft if quantum computing advances to the point where it can compromise cryptographic security.
