Bitcoin the network is fully transparent, which makes BTC not really fungible - it can and is traced, which creates better/worse BTC. This is why coinbase (small c) BTC is sold at …

Financial privacy is a must-have, not a nice-to-have feature. Financial privacy does not prevent one from being able to pay taxes. But it definitely prevents this type of attacks.

Telegram does not have any meaningful e2e encryption (apart from 1-1 on-demand stuff nobody uses). So yes, everything is visible to Telegram.

You are welcome! ZKSnarks are really mind-bending tech and are a lot of fun!

1) pepesza finds "42424242" 2) Signature = sign("42424242", privk_pepesza) 3) Witness = Circuit("42424242", Signature, pubk_pepesza). `Circuit` program will validate things I've me…

The trick is to sign the secret, not the proof. And than to prove inside the circuit following claims: 1) secret (provided as a hidden input) is correct a solution to the puzzle 2)…

I think we are talking about three different scenarios. You are describing attribution problem. "Solution to the puzzle is no longer a secret, it is a public knowledge. Who was the…

Why would it? Both signatures and snarks are non-interactive. And since you prove any(*) computation with a snark, you can prove that computation that verifies something (signature…

There are multiple ways of pulling this off. Signatures are zk-proof systems, just a very specialized ones. So you do it every time you sign a message. See my other comment on how …

> Does such a mechanism exist? Sign the puzzle solution with your private key. Check signature inside the circuit. This obviously can't be applied to this particular game since it …

Think of Kessler syndrome. One can imagine that blowing (small) N of them would create a cloud of shrapnel posing danger for the whole network. Birds are on really low orbits, so i…

Coming from Erlang to Elixir - I find Elixir docs lacking in both coverage and terseness.

Don't give them any info. Write something along the lines of "transfer of money", always. Use separate channel to communicate "why". Every bit of information you give them will be …

Technically unfeasible considering how much time he had to go through those docs (likely - very little).

> It's interesting how something which was built on the idea of decentralization by design has given way to a clear power structure, where those who have the sway to control the fa…

Monero, Zcash, Grin. Three designs that are based on different cryptography - all three giving user full privacy.

Visa is very expensive. How about that?

Not all cryptocurrencies add public record. Examples: ZCash, Grin.

They are doing beacon chain (a distributed unbiasable verifiable random number generator, constructed using commit-reveal scheme + VDF to fix commit-reveal biasability) to choose s…

Offtopic. DLT is basically a marketing fraud. Both "permissioned" and "permissionless" DLT are packed into one term. Problem is - they are vastly different. Permissioned DLT is not…

Plasma is not for payments. It is a counterpart of Lightning Network, but for code. With LN you can do a lot of extremely cheap payments. With Plasma you can do the same for arbitr…

You can do Proof of Authority instead of Proof of Work to cut down costs. The real reason behind techniques such as PoW instead of just Distributed Byzantine Fault Tolerance algori…

Those will be addressed with Lighting Network [0]. ATM there are ~4 implementations of the concept. None is complete/mature yet. [0] - http://lightning.network/

Because encryption without authentication is prone to MITM attacks. WebTRC does not have auth layer.
