I disagree with respect to Renaissance in particular, but I think others will probably comment on that point adequately. Instead, I’ll address this: > It makes more sense to me, due to a conviction on efficient market hypothesis. I enc

Mod suggestion - make an addition in the title to indicate that this vulnerability is from October. I run a public OSS mirror website and had a moment of panic before I read the details :) Also - this specifically impacts 3.1.3-dev.

Wow, seriously? That’s unfortunate. I have a significant amount of bare metal storage space and computation resources and would be happy to host benchmarks like these.

by dsacco 9y ago
Does anyone here have direct experience with being sued for releasing a benchmark online? I’m interested in seeing how common (and enforceable) it really is.

by dsacco 9y ago
It’s easy to believe that, but if you can’t reasonably quantify it based on anything empirical, why bother? It’s a cognitive blind spot to assume communities you’re a part of have a higher mean intelligence than the general population :)

This is not access to anything. This is a static dataset.

I would quibble with this, because in general things like share price have little impact from security breaches unless it’s something like medical R&D. But instead of taking that argument I’m going to say this: I have been heavily invol

That sounds more like you’ve never been on the receiving end of a bug bounty program :)

I’m sorry, but all of this comment is incorrect. 1. Vulnerabilities in the individual websites of specific companies have typically little to no salable value on a “open market”, black or otherwise. 2. People who manage bug bounty programs

That’s not the point. Step away from the idea of one market maker intermediating a trade between a buyer and a seller who would otherwise miss each other. Conceptually, automated market making improves liquidity by enhancing price discovery

You can implement a distributed application as an application running on a blockchain. This can achieve comparable throughput to a centralized exchange. Tendermint outlined this use case for their Cosmos network.
