Wall Street broker Bernstein published research arguing that while quantum computing poses a real threat to Bitcoin, it represents a multi-year upgrade cycle rather than an existential crisis, with risks concentrated in older wallets and exposed keys.
Algorand jumped 50% after a Google Quantum AI research paper highlighted the blockchain as a live example of post-quantum cryptography implementation, while warning that quantum computers could threaten Bitcoin and Ethereum's current cryptographic security.
Google researchers published findings showing quantum computers may require 20x fewer qubits than previously estimated to break elliptic curve cryptography used by Bitcoin and Ethereum. The research suggests fault-tolerant quantum machines capable of threatening crypto security could arrive by 2029-2032, accelerating industry urgency around post-quantum upgrades.
