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.

Payy Unveils Privacy-First L2 for Institutional Capital: Why $BMIC is the Missing Layer of Quantum Defense

Payy has launched a privacy-focused Ethereum Layer 2 solution using zero-knowledge proofs to enable institutions to settle transactions on-chain without exposing sensitive data to competitors. While this addresses transparency and front-running risks, it doesn’t protect against the long-term threat of quantum computing, which could decrypt current cryptographic systems. This vulnerability is where BMIC ($BMIC) positions itself as a critical security layer. It introduces a quantum-resistant financial stack using post-quantum cryptography (PQC) to safeguard private keys and assets from future quantum attacks. BMIC’s architecture includes AI-enhanced threat detection and integrates with ERC-4337 smart accounts for a user-friendly yet highly secure experience. The project has raised over $432K in its presale, with the token priced at $0.049474. $BMIC supports ecosystem operations through a "Burn-to-Compute" mechanism and enables quantum-secure staking. As institutional adoption of privacy L2s grows, BMIC aims to become an essential component in protecting high-value on-chain transactions from quantum decryption threats.

The Quantum Computing Threat to Bitcoin

Bitcoin faces an existential threat from quantum computing, which could break the elliptic curve digital signature algorithm (ECDSA) securing the network. Approximately 25% of all bitcoin—including the 1.1 million BTC in Satoshi’s wallet—are stored in vulnerable early "pay-to-public-key" addresses, where public keys are exposed on the ledger. Later address types only reveal public keys during transactions, creating a brief attack window. The timeline for quantum computing is uncertain, but if it emerges before Bitcoin transitions to post-quantum cryptography (PQC), attackers could steal and liquidate billions in bitcoin, causing a market collapse. A coordinated migration to quantum-resistant algorithms is urgently needed, though implementing PQC could take 6 months to 2 years. A controversial proposal suggests "burning" un-migrated coins to prevent mass theft, but this risks setting a precedent for confiscation and contradicts Bitcoin’s core principles of individual sovereignty. As the largest financial "honeypot" with direct and liquid value, Bitcoin is a prime target. The network must proactively upgrade before quantum computers become capable of breaking current encryption.

Ethereum Builds Team To Guard Against Quantum Threat

The Ethereum Foundation has formed a new Post-Quantum (PQ) team, led by Thomas Coratger, to prepare the network for potential quantum computing threats. The team, which includes cryptographers and engineers, is transitioning from research to practical testing on devnets. Their work involves developing quantum-safe tools and testing new algorithms while ensuring current transactions remain unaffected. A $2 million prize pool has been announced to encourage improvements in quantum-resistant solutions, including $1 million dedicated to enhancing the Poseidon hash function. Multi-client devnets are already active, with biweekly research sessions and a Post-Quantum Day planned for March 2026. Although the quantum risk is not immediate, Ethereum is proactively addressing it to ensure a smoother transition and better protect users and the network. Community reactions are mixed, with some praising the initiative while others express concerns about implementation and wallet upgrades.

‘Time to go full PQ’ – Ethereum Foundation launches post-quantum push

The Ethereum Foundation (EF) has declared post-quantum (PQ) security a top strategic priority, aiming to accelerate its development with a target to "go full PQ" by 2026. A dedicated team has been formed to lead this initiative, focusing on making Ethereum quantum-resistant. The EF is offering a $1 million prize to improve the Poseidon hash function as part of its emphasis on hash-based cryptography. PQ developer networks are already in progress, and a formal roadmap will be released soon. In contrast, the Bitcoin community remains divided on the urgency of quantum threats. Some analysts suggest that if it lags in PQ readiness, Ethereum could significantly outperform Bitcoin in returns, potentially by 200%.

Bitcoin Should Wait On Quantum Fixes, Says Epoch Ventures

Epoch Ventures founder Erik Yakes advises against rushing quantum-resistant upgrades for Bitcoin, arguing the quantum computing threat remains unproven and premature action could impose long-term efficiency costs. He attributes recent quantum anxiety to behavioral biases rather than technical evidence, noting quantum computers haven't factored numbers larger than 15. Yakes emphasizes that quantum-resistant signatures currently consume excessive block space, potentially reducing network throughput. He recommends leveraging existing taproot address features for short-term protection and allowing more efficient solutions to develop. Governance challenges and the risk of locking in inefficient protocols outweigh immediate quantum concerns, which he considers less urgent than geopolitical or monetary risks.

Ripple Advances Zero-Knowledge Proofs For The XRP Ledger

RippleX, the development arm of Ripple, is actively prototyping zero-knowledge proof (ZKP) capabilities for the XRP Ledger (XRPL). According to Aanchal Malhotra, Head of Research at RippleX, this initiative aims to introduce "programmable privacy," trust-minimized interoperability, and a scaling model that offloads heavy computation to layer-2 systems while XRPL remains the settlement layer. Malhotra emphasized that integrating ZKPs into XRPL is complex and requires custom development rather than using off-the-shelf solutions. The approach involves a hybrid implementation—some components native for performance, others in a programmability layer for developer choice. Key benefits include selective disclosure for compliance (e.g., proving age without revealing exact data), reducing reliance on trusted intermediaries in cross-chain bridges, and scaling via succinct proof verification on-chain. The goal is to enhance XRPL’s competitiveness without compromising on flexibility or security.

Popular Strategist Removes Bitcoin From Portfolio Due To Quantum Threat — What’s Happening?

Popular strategist Christopher Wood, global head of equity strategy at Jefferies, has removed a 10% Bitcoin allocation from his model portfolio, citing the emerging threat of quantum computing. Wood expressed concerns that advances in quantum technology could compromise Bitcoin’s cryptographic security, potentially allowing attackers to reverse-engineer private keys and undermine the blockchain’s integrity. He reallocated the exposure equally to physical gold and gold mining stocks, reflecting a shift away from Bitcoin as a long-term store of value. This move aligns with growing unease in the market, as other experts like Charles Edwards of Capriole Investments have recently warned that quantum risks may be developing faster than Bitcoin’s ability to upgrade its defenses. At the time of writing, Bitcoin was trading around $95,370.

The First Bitcoin Transaction Turns 17. Who Received These Coins

The first Bitcoin transaction occurred 17 years ago on January 12, 2009, when its anonymous creator, Satoshi Nakamoto, sent 10 BTC to developer Hal Finney. This event marked the symbolic beginning of the digital currency era. At current prices, those coins would be worth approximately $900,000. Hal Finney, who passed away in 2014 from complications of ALS, was a pioneering cryptographer and a key early supporter of Bitcoin. He was an active member of the cypherpunk movement, co-authored the PGP encryption system, and was one of the few people with whom Satoshi Nakamoto actively corresponded. Finney helped debug Bitcoin's early code and was its first user. Finney himself made an early and remarkably prescient prediction that if Bitcoin succeeded, a single coin could theoretically be worth $10 million. He acquired his bitcoin through mining and stored them offline for his heirs. Although he denied it, his deep cryptographic expertise and early involvement have led to persistent speculation that he might have been Satoshi Nakamoto. His legacy is that of a fundamental contributor to the blockchain and privacy technology industries.
