Fhenix believes that DBFV represents a key breakthrough in the performance of privacy-preserving computation, smashing through the bottleneck of fast encrypted arithmetic
Fhenix Unveils DBFV
Fhenix, a pioneering developer of encrypted smart contracts with fully homomorphic encryption (FHE), has announced a new milestone for blockchain privacy with the development of its cutting-edge Decomposed BFV technology.
In a press release shared with Cryptowisser, the team said DBFV is a groundbreaking new cryptographic technique that’s poised to transform the performance and scalability of exact FHE schemes. It will also enable robust, high-throughput privacy-preserving computation for real-world applications.
Per the team, FHE allows computations on encrypted data without ever having to decrypt it. It has tremendous promise for data privacy, potentially enabling the secure processing and analysis of sensitive information.
Despite that, FHE has yet to live up to this promise, for the technology has always been constrained by a key performance bottleneck – namely, the catastrophic scaling of computational costs and noise when performing arithmetic on large numbers.
The scaling challenge of FHE is especially obvious in exact schemes such as BFV and BGV, which are essential for computing financial logic due to the requirement of perfect precision.
Accelerated Computational Throughput
Fhenix explained that its DBFV represents a paradigm shift for encrypted arithmetic. It decomposes single, large plaintext data into smaller, independently-managed BFV ciphertexts or “limbs” during the encryption process, improving the throughput and scaling behavior of FHE.
Furthermore, by boosting the noise management process, DBFV supports the use of deeper circuits before costly bootstrapping is required. It manages noise more efficiently across multiple “limbs,” expanding the useful depth of computation.
Unlike the standard BFV, DBFV’s avoidance of frequent bootstrapping significantly reduces the overall computational cost of noise remediation. It also enables the cost-effective computation of sustained encrypted workloads, making FHE viable for decentralized finance protocols and enterprise-grade blockchain solutions.
According to Fhenix, DBFV will support the development of a new generation of FHE applications that require speed and precision, including financial logic, stateful applications, and high-volume data aggregation.
Fhenix added that it intends to integrate DBFV as a foundational element of its infrastructure later this year, weaponizing pure cryptography to eliminate a bottleneck that many thought could never be overcome
Fhenix is a research and development company pioneering encrypted smart contracts with fully homomorphic encryption (FHE). Starting with a laser focus on Private DeFi, Fhenix is building the infrastructure to bring FHE everywhere - empowering developers, institutions, and users to create and use financial applications without sacrificing confidentiality or composability.
