Crypto Firms Rush to Secure Wallets Against Quantum Threat

Crypto firms are taking proactive steps to secure their wallet and custody offerings against the looming threat of quantum computers, which could compromise current cryptography by 2030. According to estimates, quantum computers may be able to break current encryption within a matter of years, prompting companies to act early.

One such company is Silence Laboratories, which has developed a post-quantum secure signing layer that can be integrated into existing infrastructure without requiring significant changes. The firm's approach uses distributed or multi-party computation (MPC) signatures, which split private keys across multiple devices to protect against quantum attacks.

The use of MPC systems allows companies like Silence Laboratories to upgrade their wallet offerings while network-level upgrades to blockchains like Bitcoin and Ethereum are still in progress. This approach is seen as a temporary solution until the underlying protocols are updated.
