Yea it's the same as a hash collision, maybe they managed to type some other message that hashes to the same thing but it's very unlikely. You can also use multiple different types of ZK proofs for the same data, same as using mul

ZK STARKS can be done without a trusted setup, they are slightly different from ZK SNARKS. I believe it's possible to do a trusted setup with many hundreds or thousands of anonymous people too, someone would need to get every single co

ZKPs have only become cheap and easy enough to do in the last few years, so of course Goldman Sachs doesn't use them yet. They'll be using them in a decade, for now look at startups. https://github.com/zk-passport&

The ID would need to have some government digital signature for the ZK circuit to work. The proof would be "this digital ID that has this valid government signature shows XYZ". The verifier would need the government public key and

The hash check is binary, you can only check if a password is correct or not. The ZK proof can prove anything, like that the password has enough special symbols and numbers that it's secure. There's no way to check that someone&#x

50% of Australia lives in Brisbane, Melbourne and Sydney. Having a nuclear power plant for each would make sense. Melbourne would make the most sense first as it gets a lot less sun than the others.

I went through the same thing last few years. Ended up joining a venture capital firm as a technical researcher and love it. I focus on crypto most of the time, and sometimes robotics, AI or developer tooling. I mostly talk to startups abou

Coinbase + USDC are essentialy this now. They've started working with many merchants both in the real world and online to add USDC pay and transactions are less than a cent with Coinbase charging no additional fees.

Only needs to be done once though. I tip and buy things all the time with my crypto wallet now, and it's less than a cent per transaction. Just waiting on more sites and stores to support it. Credit cards were also a PITA when they fir

There's a few new proof of human systems out there. For each of these you have a private key and the service attests that "the holder of this key is a human". Then when you sign up to a service you can create a ZK proof that

I don't understand how they lost their startup though? Doesn't the accelerator only take a small percent?

Foreign students pay 2-3x as much as Australians do to study in Australia. Allowing rich Chinese children to study abroad contributes a lot to Australia's economy and those high fees subsidise everyone else which allows keeping local t

> I'm not talking about any services that allow password reset through SMS alone - that's beyond idiotic, obviously. Twitter allows this, it's been a security flaw for years they've never fixed, and it's possible

There's a service called 3Num where you can get a number controlled by a private key. No one else has access to your number/account. Only supports SMS messages currently though, it's not a full phone service.

I work in crypto and see Sim swaps happen all the time, mostly for Twitter account takeovers of famous people where they then post phishing links and steal their followers coins. T-Mobile is easily the biggest offender for this, most people

Cockatrice has been around for a while without getting a C&D. They separate the game client from the card images to get around it. Could do similar.

by TimJRobinson 3y ago
The reason L2s can scale that high is every machine doesn't have to process every transaction. Each L2 is its own chain that uses its own sequencer/s. The blocks from this chain are then compressed into a single blob of data with

It is amazing how prescient the book "The Sovereign Individual" is despite being written in 1997. I recently re-read it and it's spot on with what's been happening lately. Highly recommend if you want to better understan

A real layer 2 would look more like something built on Ethereum (can see all its L2s at https://l2beat.com ). Essentially it's a separate network that every few minutes takes every transaction and compresses it into a data b

I think this is a large part of why many Americans in particular don't understand crypto. They already have access to the world's best financial system and all the protections of the state when using it. Living in Australia and tr

It's a database optimization. Whenever you send funds that entire UTXO is destroyed and redistributed to new ones. Because of this you can easily calculate the current state of Bitcoin by only looking at the current UTXO set, and ignor
