Vitalik Buterin
Co-founder of Ethereum. Publishes long essays on mechanism design, governance and what cryptography is for, and returns to his earlier positions to say which parts he no longer holds.

Where they publish
vitalik.eth.limoSite Their site: the long essays, going back years.
The full archive of their writing on Ethereum, governance, cryptography and the politics of the technology. Long-form and technical; the ENS domain resolves to the same archive as the older vitalik.ca. Has a feed.

Local mixing, a new cryptographic obfuscation approach, is a risky bet resembling past failed attempts at white-box cryptography.
This is a wild and risky bet; it sits on a graveyard of failed attempts at white-box cryptography .
Obfuscation (Part III): Local Mixing Said 21 Aug 2026
A sufficiently large random reversible circuit is plausibly a secure cryptographic permutation, while a large random irreversible circuit collapses to only a few possible outputs.
A big-enough random reversible circuit is plausibly a secure cryptographic permutation, a big-enough random irreversible circuit degenerates into having only a few possible outputs.
Obfuscation (Part III): Local Mixing Said 21 Aug 2026
As of 2026, local mixing has not yet sufficiently eliminated correlations between original circuit values and their obfuscated counterparts.
But, so far, mixing has not proved to be good enough. There ended up being too many correlations between values in \(C\) and values in the obfuscation that remained.

Obfuscation: building the final boss of cryptography (Part I) Said 29 Jun 2026
Building a secure obfuscation protocol is extremely difficult.
it turns out that making a secure form of obfuscation is really really hard
Obfuscation: building the final boss of cryptography (Part I) Said 29 Jun 2026
Current provably-secure indistinguishability-obfuscation schemes have galactically impractical runtimes.
But within the good news, there is bad news: the run time is literally galactic
