Quantum Computing Poses Greater Threat to Crypto Than AI, Warns Coinbase CEO

Key Highlights Advanced quantum machines running Shor’s algorithm pose a future threat to elliptic-curve cryptography, creating risks for exposed public keys across blockchains. Coinbase released a technical proposal outlining core priorities to prepare Bitcoin for post-quantum resistance, including flexible signature schemes and handling dormant coins. Global entities, including Europol and the U.S. National Institute of ...

New Quantum Model Slashes Hardware Needed to Break Bitcoin Keys by 17 Times

Key Highlights Research from quantum computing firm Alice & Bob indicates that Shor’s algorithm could be deployed against cryptographic systems sooner than anticipated, prompting calls for an immediate transition to post-quantum security. A modeled quantum attack on Bitcoin would currently require approximately 62 minutes—slower than the network’s 10-minute block confirmation window, yet dangerous for exposed ...

Renowned Bitcoin Advocate Nic Carter Issues Warning: “It Will Definitely Happen Within 10 Years”

Key Highlights: Venture capitalist Nic Carter has accelerated his quantum computing forecast, projecting that quantum capabilities will reach critical cryptographic thresholds within the next decade. Carter advocates for proactive Bitcoin network upgrades via a soft fork to post-quantum signatures, alongside a controversial proposal for the U.S. government to secure dormant early coins, including those belonging ...

Bitcoin and Ethereum Take Contrasting Paths to Post-Quantum Crypto Wallets

Key Highlights: Bitcoin proposal BIP-360 alters Taproot spend paths to conceal public keys, but explicitly does not introduce post-quantum signatures or protect exposed keys during transaction broadcast. Ethereum smart accounts can already verify hash-based signatures like SPHINCS+ via the EVM, though native solutions like EIP-8141 frame transactions remain in early draft and testnet stages. Hardware ...

As Tezos, Algorand, and QRL Go Quantum-Ready, Where Does Bitcoin Stand with BIP-360?

Key Highlights: Google research suggests quantum computers could break exposed Bitcoin public keys in roughly 9 minutes, threatening transactions pending in the mempool during standard 10-minute block confirmations. Over 6 million BTC—worth between $500 billion and $600 billion—sit in addresses with exposed public keys on-chain, while Bitcoin’s proposed BIP-360 upgrade offers risk reduction rather than ...

Starknet Prepares to Exit Ethereum as STRK Plunges 41%

Key Highlights: The Starknet community voted to study transitioning from an Ethereum Layer-2 rollup into an independent, post-quantum Layer-1 blockchain, backed by a joint StarkWare and Starknet Foundation working group. StarkWare CEO Eli Ben-Sasson argued that Ethereum’s targeted December 2029 post-quantum timeline is too late and susceptible to schedule slips, justifying Starknet’s target for 2027. ...

Starknet Unveils Falcon Challenge Aiming to Reduce Costs and Boost Performance

Key Highlights: Starknet has introduced the Falcon Challenge to incentivize developers to optimize quantum-resistant signature verification. Gas costs for verifying quantum-safe signatures on the network currently stand at 48.4 million gas. The initiative seeks to reduce verification overhead below the existing record benchmark of approximately 26 million gas. Ethereum Layer-2 scaling network Starknet has officially ...

Google Achieves ‘Magic State’ Quantum Breakthrough as Top 5 Quantum-Proof Blockchains Emerge

Key Highlights: Google Quantum AI has achieved “magic state cultivation” on physical hardware, cutting error rates 40-fold on its Willow processor while using only about half of its 105 physical qubits. Despite the leap forward, existing cryptocurrencies like Bitcoin remain secure for now, as breaking Elliptic Curve Cryptography (ECC) requires a 100,000x scaling of current ...

Google Touts ‘Magic’ Quantum Breakthrough as Bitcoin Q-Day Threat Looms

Key Highlights: Google has developed a novel quantum computing technique to resolve processing bottlenecks by filtering out noise and transferring purified quantum states between error-correction architectures. Earlier research suggests that breaking Bitcoin’s elliptic-curve digital signatures could require fewer than 500,000 physical qubits, potentially exposing roughly 6.9 million BTC linked to revealed public keys. Major industry ...
