Crypto Faces Years-Long Quantum Migration Cost, Experts Say

Crypto institutions face a years-long and costly shift to post-quantum cryptography as quantum computers edge closer to threatening today’s elliptic-curve security, according to BeInCrypto. The article cites experts from BitGo, Nethermind and the cryptography community, who say firms need a full inventory of vulnerable systems, while larger signatures, custody redesign and parallel classical-plus-quantum operations could raise bandwidth, storage, fees and migration costs.
