Ethereum Accounts Could Add Quantum-Resistant Signatures for $0.07 per Transaction, Nicolas Consigny Says

Nicolas Consigny said Ethereum (ETH) accounts could be protected against future quantum-computing attacks for as little as $0.07 per transaction. According to NS3.AI, a June 14 paper describes an approach that adapts the U.S. National Institute of Standards and Technology’s SPHINCS+ standard into a variant called SPHINCS-. The paper says the method would not require an Ethereum protocol change or a precompile.
