• Vitalik Buterin reignites interest in FHE, encryption tech for calculations on encrypted data.

  • FHE’s potential applications include secure cloud computing and privacy-preserving data analysis.

  • Challenges remain for FHE, such as computational cost and security vulnerabilities.

Vitalik Buterin, the co-founder of Ethereum, has ignited fresh interest in a revolutionary encryption technology called Fully Homomorphic Encryption (FHE). Buterin recently resurfaced a 2020 article he authored titled “Exploring Fully Homomorphic Encryption,” prompting discussions about the tech’s potential to transform data security.

Since a lot of people are interested in fully homomorphic encryption (FHE) recently, re-upping my article from 2020 that goes into how the math works in depth:https://t.co/TuHK3DoJrZ

FHE’s unique selling point is that It allows users to perform calculations on encrypted data without ever decrypting it. This opens a world of possibilities for data privacy.

Buterin’s re-promotion of the article occurred because of the fresh interest of the public around FHE’s practical applications. This could be a game-changer for several sectors. Cloud computing could become significantly more secure as sensitive data could be processed in the cloud while remaining encrypted. 

According to Buterin’s article, while FHE’s potential is undeniable but challenges still remain. The computations performed on encrypted data can be computationally expensive and impacting processing speeds. Additionally, FHE is a new technology which requires further research to optimize performance and address security vulnerabilities.

However, Buterin’s focus on FHE gives optimism to the crypto community for the future of data security and privacy. Additionally, Vitalik’s article states that as FHE matures, its applications could extend far beyond the initial areas of interest shaping the way we handle sensitive data in an increasingly cloud-reliant world.

Vitalik has always been one for the safety measures, the founder recently revealed that 90% of his crypto is held in Multi-Sig Service. In a multi-signature solution, users hold some keys but are unable to recover the funds independently. A multi-sig solution is recommended to minimize the personal risks associated with hardware wallets.
