From YouTube: Chainsafe: Investigating privacy on Ethereum using ring signature based mixing - Elizabeth Banks

Description

Berlin Ethereum Meetup 2019/01/24

A

Research, so yeah, so when my first site is basically the city soaring signature bass, mixing materials is like a simple concept of privacy, so basically our signature is to normally when you side and potentially it's signed by at 100 Paulo key. So you know that the signature came from this person with a real signature. The signature is created using a group of kids and then will be won by murder of the group actually creates the signature without all the signatures. Conformity can't tell from the.

B

Outside who decided so.

A

B

You decide, the transaction is weighing.

A

Stuff with just your own key you'll, be able to like plausibly deny that you are involved in the transaction. This is part of the way.

A

A

B

There are powers that was a user, would.

A

Submit a public key to the contract as well as the deposit. This is positive things about either, as well as the ring size. Then in the contract, it probably says like 11, because that's when your users, but so.

B

A

That amount of people has.

B

Admitted public.

A

He hadn't faucet to the contracts that were enlisted poll that list public he's from the contrast and created a researcher, so so the initial public that you have submitted it could be. You got the receiver of this induction.

B

A

Corresponding private key so.

B

C

Perhaps talk to the receiver beforehand.

A

There this video this way so all.

B

They talk to the recipe beforehand. It's under public contracts, person either.

A

Then once the husband filled with nutrients or the recipient now has the private key of one of the keys in the ring. They were now create the signature.

B

Sighting and off basically saying.

A

Send me the ether and that was deposited into this contract and that.

A

Or, alternatively, the center we're doing an apology and then they would create the signature that.

B

A

Does it mean that they think we're talking the contract so yeah.

A

So yeah, so the first issue was possibly implemented. Yes, my signature is super large, so you can actually store it. Signature with more than five members on.

A

So you can't perform the verification that we needed to in one spot, but enough ringing the set with different size. That would be actually useful could if there is too small it's easy to sort of box race to see like second box. Is he going so a possible solution? One us or somebody was just being a pre-contract on fair harvest and then eventually.

A

Wasn't God and seems towards the bar, which is cool, but for talks about, must be presented to take. Yes,.

A

256 miles and hopefully not.

A

B

Yeah so create.

A

New solutions need privacy. You can create a signature on chains.

C

You have to solve.

B

It object and then do.

A

The verification.

C

B

This is a variation on of.

A

The original signature so.

B

A

What we features BCI's another image.

B

A

A

B

A

Saying if you're trying to submit a signature to the contract again be.

B

Noisome it what deposit.

A

And like no I can't do it. So yes, so.

B

Some extensions.

A

In us that I was thinking of so I think was just generalized transaction privacy. So right now we do. It makes me think of like ether sort of probably but.

A

B

A suitable, the call T this is.

A

What's happening in the mixer is the ACP that you have like a transaction and then this tender she gets signed us Iranian marketed and your thing said actually could.

B

A

B

A

The contractor out needs a fix easier to audition, because these people help people to set whatever I'll. Also contracted may be able to link the side of the recipient, so I would be like pretty cool I think so. I think I'm. Just really amazing people, because American photographers, since 2000 is a box of this is people to decide. Oh yeah.

A

C

B

Me forgive me for.

C

How superficial is questioning, but as an end user cares about privacy? How would you compare and contrast ring signatures with something like a sea cave snarls, because I know I.

B

See pig snorts.

C

I think, like only 15% of exchange, is actually influenced seek a snark. So what is like the pros and cons to ring at.

A

And just it can fight as useful.

A

C

Which would be.

B

Just an observation Bishop about the transaction, it will become a cop theta and the who is going to pay me for the gods, etc. I definitely is just about the transactions you can have. You know very like just to have a layer layer who will pay for that one. Just by very you can consider me.
