How Much Bitcoin Is Quantum-Vulnerable? Researcher Says 6.9 Million BTC

Project Eleven CEO Alex Pruden disputes a CoinShares report estimating only 10,200 BTC are quantum-vulnerable, arguing that approximately 6.9 million BTC—including coins in addresses that have signed transactions at least once—could be at risk if quantum computers advance faster than anticipated. He emphasizes that once a public key is exposed on-chain, any remaining funds in that address become vulnerable to quantum attacks. Pruden specifically highlights Satoshi Nakamoto's estimated 1.1 million BTC as a large vulnerable target. He criticizes the notion that quantum threats are distant, citing evolving research and warning against complacency. The transition to quantum-resistant cryptography would be operationally complex for Bitcoin’s decentralized system, potentially requiring significant downtime and coordinated effort.

Bitcoin’s Quantum Risk Is Smaller Than Feared, Researcher Says

A recent analysis indicates that Bitcoin's vulnerability to quantum computing attacks is less severe than commonly perceived. While concerns persist about future quantum machines breaking cryptographic protections, the immediate risk is limited. Reports highlight that only approximately 10,230 BTC, valued at several hundred million dollars, are held in addresses with exposed public keys, making them the most susceptible targets. These are primarily in mid-to-large-sized wallets, many dating back to Bitcoin's early days. Current quantum hardware remains insufficient for such an attack, operating at just over 100 qubits, whereas millions of stable, error-corrected qubits would be required. Experts like Andreas Antonopoulos and Adam Back emphasize the need for proactive preparation rather than panic. They recommend developing upgrade paths, discouraging key reuse in wallets, and testing migration procedures to ensure a smooth transition if quantum risks materialize in the future.

Australia Interest Rate Hike Fears Influence $BMIC Macro Investment Tones

The Reserve Bank of Australia (RBA) has raised the cash rate by 25 basis points to 3.85%, signaling a hawkish stance amid persistent inflation and a tight labor market. This contrasts with other major central banks and reflects a 'higher for longer' interest rate environment. The tightening monetary policy is driving investors toward secure, utility-focused assets rather than speculative ones. A key emerging risk is the 'Harvest Now, Decrypt Later' threat, where encrypted data is collected now to be decrypted later using quantum computing. This has increased interest in quantum-resistant cryptographic infrastructure. BMIC ($BMIC) is highlighted as a project offering a post-quantum financial stack that eliminates public key exposure risks, using AI-enhanced threat detection and ERC-4337 Smart Accounts. The project has raised over $444K in its presale, indicating investor confidence in quantum-proof blockchain solutions as essential future-proof infrastructure.

Fhenix Breaks Blockchain Privacy Barrier With Decomposed BFV Encryption Breakthrough

Fhenix has developed a new cryptographic technology called Decomposed BFV (DBFV), a breakthrough in fully homomorphic encryption (FHE) that significantly improves the performance and practicality of encrypted computations on blockchain. FHE enables calculations on encrypted data without decryption, offering strong data privacy, but has been limited by high computational costs and noise accumulation, especially in precise schemes like BFV and BGV used in financial applications. DBFV addresses these challenges by decomposing large plaintext numbers into smaller, manageable ciphertexts called "limbs," which are processed independently. This approach enhances noise control and reduces the need for frequent bootstrapping—a computationally expensive process—thereby enabling deeper and more complex computations. Although some operations become slightly more costly, the overall efficiency gains make sustained encrypted workloads feasible for the first time. This innovation allows high-throughput, privacy-preserving applications such as financial logic, stateful apps, and data aggregation. Fhenix plans to integrate DBFV into its infrastructure later this year, making FHE a practical solution for decentralized finance and enterprise blockchain use cases without compromising performance or precision.
