The Block reports that Cardano co-founder Hoskinson said Bitcoin could lose its top position if it fails to handle quantum computing threats. Hoskinson argued that Cardano's governance structure and upgrade capability make it better positioned to respond to existential technical challenges.
Quantum risk to elliptic-curve signatures is real in the long run, but the framing here is mostly a governance pitch, not an imminent threat. If you build on Avalanche or Base, the more practical takeaway is to watch how quickly your chains can coordinate post-quantum signature upgrades and key migration, since that's a chain-level dependency you don't control. Worth checking whether your wallet and key-management assumptions can survive a signature scheme change without breaking users.
