My third (and last) post in my series on obfuscation (iO): local mixing https://vitalik.eth.limo/general/2026/08/21/obfuscation_part_iii_local_mixing.html Local mixing is a very different philosophy from the other two, no prior background in lattices required, and very different tradeoffs (eg. in terms of computational overhead, it's viable today; the entire question is verifying the security of what's ultimately a novel family of cryptography). I highly encourage following their work, they plan to publish much more soon.(vitalik.eth)
