According to Wu, Vitalik Buterin has written an article introducing Diamond iO, an indistinguishability obfuscation scheme that modifies BGG+14 attribute-based encryption (ABE) and runs fully homomorphic encryption (FHE) within it. This scheme redesigns input encoding generation and conditional FHE decryption mechanisms, bringing computational overhead closer to functional encryption rather than stacking multiple layers of protocols on top of it. The runtime, which the author described as 'galactic-level,' has been reduced to 'planetary-level,' though it is still not practically operational. https://(wublock123.com)/news/vitalik-on-diamond-io-obfuscation-for-privacy-computation-65499
