There are some companies that facilitate this, like EquityZen and Forge Global. It seems to be a legal gray area, since the options are legally non-transferable, so creatively structured contracts are used in an attempt to work around that.

You can make the case that using other payment systems sub-optimal from a security perspective, but malware? Would you also consider Uber, Lyft, and Amazon malware since they accept other payment systems?

I agree with your other points, but it it seems like the intent of that clause it to require Google to disclose the nature of user data being collected, not the user data itself. In particular, (a) distinguishes between user data that Googl

I think credit card transactions are even worse -- most transactions (besides authorizations) are also communicated via daily batch files, and there are several middlemen involved, with potential delays at each step. Hence "refunds usu

There are projects like Miximus, which is an Eth tumbler with no operator. Participants deposit funds into a smart contract, then when they want to withdraw later, they use zero-knowledge proofs to show that they know one of the private key

Informally, I mean reducible from time-bounded Turing machines. Given a Turing machine TM and a time bound T, a (binary or arithmetic) circuit can be constructed to simulate TM for T steps. Or in other words, a circuit can be constructed to

I don't think there's much that can be done, except trying to identify any circuitry shared among branches and moving it out. Like if we have "if (cond) { hash(x) } else { hash(y) }", we can move the hash circuit outside

In theory we could compute the full table of values of a function like less(x: F, y: F) -> {0, 1}, interpolate a bivariate polynomial containing all those values, and build a circuit to evaluate that polynomial. Its degree would be aroun

There isn't branching in the traditional sense, but we can work around it. Instead of doing result = if condition { a } else { b } in circuit programming, we normally do result = condition * a + (1 - condition) * b

Most programming languages support unlimited nesting (of parentheses, code blocks, etc.), so wouldn't they require at least a pushdown automaton?

Hm, you're making sense otherwise but I just don't see where I assumed P(Global Epidemic starts in Wuhan) = 1 -- could you elaborate on that?

by dlubarov 7y ago
Yes, I assumed that if the virus is not from the WIV, then all areas of China (weighted by population) would be equiprobable candidates for the outbreak location. Of course this is an imperfect model, but I think it's a reasonable one.

I threw out 1% as a seemingly reasonable prior probability that the outbreak came from the WIV, given an implicit assumption that the virus originated in China. Obviously I didn't put much thought into the exact number, but 1% seems wi

I don't quite follow your point. My model assumed implicit knowledge that the virus originated somewhere in China, but not in Wuhan. Maybe I should have made that more explicit. We could change the model to not have any implicit assump
