Ledger CTO: Quantum Computer Unlikely to Break Bitcoin In Near Term
Charles Guillemet, chief technology officer at hardware wallet giant Ledger, has opined that a quantum computer is unlikely to break Bitcoin's current cryptography.
That said, Guillemet believes such a black swan event is not impossible, and the quantum threat should not be ignored.
Guillemet has argued in favor of proactively upgrading the current Bitcoin protocol in order to make sure that it remains quantum-resistant. This would require defining a "migration path," which would include those coins that are presumed to be lost (such as Satoshi Nakamoto's enormous 1.1 million stash).
Guillemet has warned that such migration would come with trade-offs. The Ledger CTO has warned that lattice-based cryptography, which is considered to be the leading candidate for quantum-resistant encryption, is still relatively new and unproven. "Lattice-based post-quantum cryptography hasn’t yet stood the test of time, and hash-based schemes feel archaic," said Guillemet.

Willy Woo Urges Bitcoin Holders to Migrate from Taproot Before Quantum Era
On-chain analyst Willy Woo issued a guide urging Bitcoin holders to move coins from Taproot addresses to older formats that conceal public keys behind cryptographic hashes, warning that quantum computers could compromise exposed keys as the technology matures.
The Bitcoin community remains divided over the urgency and effectiveness of migration strategies as quantum computing timelines compress toward the late 2020s.
Woo’s post on X outlined a six-step process for holders to protect their Bitcoin during what he called the “age of big scary quantum computers.”
Taproot addresses beginning with “bc1p” embed public keys directly into addresses, making them vulnerable once quantum machines develop enough processing power to derive private keys from public ones.
