Bitcoin’s quantum security problem may be more complicated than simply upgrading its signature system.
One detail that caught my attention is the challenge of restoring an old wallet backup. Under the proposed SHRINCS scheme, a signature could reach 5,777 bytes, while smaller signatures starting at 548 bytes depend on maintaining a reliable signing history.
That creates a difficult trade-off. Smaller signatures help reduce blockchain data, but what happens when someone restores an old wallet and no longer has the history needed to sign securely?
For Bitcoin, protecting coins against future quantum attacks is only one part of the challenge. Any solution must also work for long-term holders, forgotten wallets, and people recovering backups years later.
Quantum resistance sounds promising, but recovery and usability could determine whether the upgrade works in practice.
Would you prioritize stronger security or a simpler, more reliable wallet recovery process??
