Interesting! I’ve thought before about using non-censorship of transactions as a soft validity condition for blocks, but my conclusion has generally been that it would lead to too much network instability if there’s disagreement about what txs have been published…. Continue Reading →

Doesn’t this mean that if a single validator is malicious they could delay the inclusion of any transaction for 40 blocks? (I don’t mean by going offline, I mean by censoring) Or am I not understanding correctly?

Thank you for engaging! > All of this would be impossible without the assumption of an honest majority. It’s not quite an honest majority assumption; proofs of custody protect against the particularly likely class of dishonest rational behavior that is… Continue Reading →

> “Laws of physics” are human constructs, and as such are socio-legally bounded and inherently mutable. Huh? This feels like it’s veering into post-modernist territory. Laws of physics are NOT a social construct; our interpretation is, but the laws are… Continue Reading →

I don’t think this framing of blockchains vs law as some kind of Great Battle To Determine the Future of How Society Does Dispute Resolution is productive (and yes, I am aware that I myself used to promote such framing… Continue Reading →

> He imagines a world in which crypto political and legal processes are necessarily going to go against either his personal preferred political outcomes, or against the public good, and therefore must be minimized. I think that’s putting things too… Continue Reading →

The fact that people subconsciously care more about fitting in with their social group than believing the “truth” is a fact about human nature, not something created by newfangled Silicon Valley tech companies. This is part of why the problem… Continue Reading →

I feel like I mis-explained a few things in our conversation, sorry! > Unlike the previous proposals, no committee is sampled per block This is not correct. For the sake of completeness, here is how the algorithm works, with some details… Continue Reading →

Thank you so much for your help in spreading the word in places that have historically been under-represented in the crypto space! Are there any applications being developed in or for Haiti that you think are close to seeing real usage?… Continue Reading →

(Also posted on the Reddit thread) I think the example is broken. To see why, notice that we are dealing with field elements, not integers. Field elements are integers modulo p. In the Ethereum case, p = 21888242871839275222246405745257275088696311157297823662689037894645226208583. We can make a… Continue Reading →

In this specific case, I trust it because it agrees with the other signals that I was aware of at the time (long-form discussions on Reddit, long-form posts on that github thread, opinions of people I personally know……). Edit: you… Continue Reading →

I think the simplest answer to these questions is, there are some researchers in Stanford that we think have been doing very good work solving problems in cryptography and other fields relevant to the blockhain/cryptocurrency space, and we gave them… Continue Reading →

I replied why I disagree with your anti-immutability position (not the same as disagreeing with anti-immutability in general!) in tweets, but for the benefit of the public I’ll summarize. My summary of “Zamfirian anti-immutabilism” is as follows: it is highly… Continue Reading →

> Therefore I anticipate that we will someday see cryptographic breaks using tricks from complex (or higher dimensional) analysis. In some sense this is what elliptic curve pairings are.

Missed a few that I’m proud of! 13. ethresear.ch has turned into a reputable research venue with significant amounts of activity happening in multiple areas, including Plasma, sharding, Casper, economics, ZK-SNARKs, and many high-quality contributors. 14. Barry Whitehat’s work on using… Continue Reading →
