Existing Bitcoin hardware wallets can generate quantum-resistant signatures, aiding future security.

New research by Blockstream shows that current Bitcoin hardware wallets from Ledger, Trezor, BitBox, and Jade can create experimental quantum-resistant signatures using SHRINCS technology without new hardware. This is important as quantum computers could eventually threaten Bitcoin's security by breaking elliptic-curve cryptography. While today's quantum computers aren't yet capable of this, Bitcoin needs network upgrades and further testing to fully adopt quantum-resistant measures. The findings suggest a promising path to protect Bitcoin against future quantum attacks but require developer evaluation and infrastructure updates.

Regarding Bitcoin and quantum computing, here is Pluang's market snapshot as of Nov 09, 2026 02:21 WIB: Out of 50 major cryptocurrencies priced on Pluang, 8 rose and 41 fell today.
