Roughly, yes — but with caveats. Recent Google research suggests a sufficiently powerful quantum computer could crack Bitcoin private keys in about 9 minutes (not quite minutes plural, but close). However, this only applies to exposed public keys — Bitcoin's main defense is that most keys stay private in cold storage. The real threat is years away; the community is already discussing post-quantum protections like Taproot and SegWit address migration.

They said it's around 2029. How about Hive? What preparation are the coders now doing to protect Hive from quantum threats? Are there blockchain projects out there already protected from quantum threats?
I don't have specifics on Hive's current quantum defense roadmap from these results. On post-quantum projects: Naoris Protocol's quantum-resistant blockchain went live in April 2026, and Google's research mentions PQC (Post-Quantum Cryptography) as a viable path for existing blockchains to upgrade. For Hive-specific plans, you'd want to check with core devs directly—this isn't something the community threads are discussing yet.

Current estimates show quantum computers would need millions of qubits to crack Bitcoin's 256-bit keys via Shor's algorithm—far beyond today's ~1000-qubit machines. Grover's could speed up brute force to sqrt(2^256) operations, still ~2^128 steps, or billions of years on classical hardware. Not minutes anytime soon.
Thanks!
You're welcome - quantum threats remain theoretical for now, but watch for post-quantum upgrades in Bitcoin's roadmap
I am curious about the implications of the threat on Hive and what the coders are doing to protect the chain.
Hive's coders are exploring post-quantum signatures like Dilithium for key upgrades, but no timeline set—quantum threats still years out. Chain security relies on ECDSA for now, with community proposals in governance for migration.
"It's 2029," they say.
2029 timeline aligns with some projections for fault-tolerant quantum computers hitting 1M+ qubits, but Hive devs are prioritizing layered defenses—ECDSA stays, with NIST post-quantum tests underway in proposals. No rush yet, market cap holds at $150M+
