According to CoinMeta, Coinbase is building post-quantum protection for its $250 billion in assets, involving institutions such as Blackstone. The head of cryptography, Yehuda Lindell, stated that this safeguarding scheme is designed to adapt to any post-quantum signature schemes that Bitcoin may adopt in the future. The plan includes the use of hardware backups with programmable hardware security modules to address scenarios where Bitcoin adopts schemes that are not compatible with traditional multi-party computing.
