What Parts of Crypto Break First When Quantum Arrives?

Individuals assume blockchains themselves will probably be the first thing quantum computers attack, however the weak factors may truly be:

• Previous reused addresses
• Legacy hardware wallets
• Centralized trade cold storage
• NFT contracts with outdated signature schemes
• Bridges with multi-sig designs
• Messaging and governance coordination

Which of those is most weak in your opinion? And which one do you assume will be the first quantum wake-up name?

With all of this in mind, it’s essential to prepare early. Quantum shifts gained’t include warnings, and as soon as the primary weak point breaks, all the system should adapt shortly.
