Vitalik Buterin quoted
Co-founder of Ethereum
Their wordsAs an AI might say, the only honest conclusion (ok fine, the honest punchline) is that a modern cryptographic network like the post-Lean-upgrade Ethereum is called a "blockchain" to a large extent for historical reasons.

Vitalik Buterin quoted
Their wordsThe most important conclusion is that the set of tradeoffs for users is radically changing:

Vitalik Buterin quoted
Their wordsPerhaps the most important shift is that the decentralized nature of the network is shifting from being purely a burden incurred in the name of safety and robustness to at least sometimes, in a few limited cases, being a strength even from a performance perspective.

Their wordsRight now OpenAI is extremely dependent on CoT monitoring, everyone else depends on it quite a lot as well, and it looks like it may not last much longer, and that Astra already is on the edge of steganographic capabilities and can do substantial obfuscation if and only if it thinks you would think it is up to no good.

Their wordsThis is a wild and risky bet; it sits on a graveyard of failed attempts at white-box cryptography .
- VB
Vitalik Buterin quoted
Their wordsA 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.
- VB
Vitalik Buterin quoted
Their wordsBut, 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.

Programmer and writer; co-wrote The Rust Programming…
Their wordsA criticism of this boils down to "well, most users won't do that," and while that's true, I also think that's okay for most people, and that having the choice is more important than forcing every user to deal with their own key management.

Co-founder of Counsyl and of Earn.com
Their wordsAs incredible as it may sound, the blockchain is the most important development in history since the advent of writing itself, as it’s a cryptographically verifiable, highly replicated, unfalsifiable, and provably complete digital record of a system.

Colin Percival quoted
FreeBSD developer and former FreeBSD Security Officer
Their wordsWith requests going over TLS it is obviously less critical now, but end-to-end signing is always going to be better than transport-layer security.

Physicist, writer and researcher
Their wordsIdeas like public key cryptography are I mean, they're just incredibly deep um very non-obvious ideas uh which in some sense lay hidden uh already sort of in in the 1930s.

Their wordsKeeping accurate time is a critical system function, not least because it involves constant interaction with the internet and forms the basis for cryptographic verification in protocols such as Transport Layer Security (TLS).

Terence Tao quoted
Their wordsUm and uh I think we would very rapidly abandon any cryptography based on the primes because if there was a one pattern that we didn't know about there's probably more.
