Some people are just too damn smart. This is kinda hard to understand even with a nice animation to show how it works...

Really nice video Monero is a really secure coin I like how stealth addresses and ring signatures verify transactions in such a way.

[@tannobates7475]

Monero is the best privacy coin out there. Period.

the bounties offered by the US Gov. and others certainly prove that handily, don't they? LOL fuckers just have to know everyone's business...what are they afraid of anyways? that people might not use greenbacks for their criminal activities any more? doesn't make much sense, does it?

If i got it correctly, it's like throwing big rocks around with your friends. The guy whoose window got smashed knows that one of the five of you threw the rock, but he doesnt know who exactly. All 5 of you except the true sender are completely blind but nobody knows who the one is who isnt blind. So what everyone knows is that one of the other 4 must have been throwing the rock and the true sender just pretends to not know who was it. The miners are just the ones who have heard a windows being smashed. Since your windows can only be smashed once your one time wallet is used after the transaction. Behind the window is just the block chain and chiseled into the window is an encrypted message. A message only the recipient can decrypt making him able to take advantage of it. That way there is no direct link between sender an recipient, like if you had hidden a letter somewhere but nobody exept the intended recipient knows where you left it. In that letter is the sent amount of XMR. I really hope I got it correctly but chances are I didnt, since this is a quite complex but genius system.

will we ever run out of windows? (one time keys)

[@connormcbrayne665]

Would be nice if you did a version of this for people who do understand that inner workings of a computer as I'm still confused how they're able to hide the transaction amount whilst also being able to know how much is being given to another wallet.

Cool stuff! Maybe add a couple links (cards and annotations) within the video. It will help you drive interested traffic.

How many decoys (signers) are there for any given transaction? Thanks.

From today 15, before was 10.

No that's not good, this satisfies no audience: it's too complicated for random persons and not in-depth enough to make CS majors understand it either This should be 10mins long and include why what and how

i haven't used my mind that much since my senior year as a CS major!! and sadly, i still don't fully get this... :-\

@@disco.jellyfish yeah i think you did. what is probably most important is that the "dummy" friends change each time and are selected from a big pool of addresses, making for nearly no discernable patterns...

[@themadcow686]

So it's basically like a Bitcoin tumbler?

[@ZacheryGlass]

Not really. With a Bitcoin tumbler, an attacker could see that you send a transaction, how much you send and when you sent it, they just can see where that money is going. With RingCT, an attacker would see that your output was used in the transaction, but they can't be sure that you actually made a transaction because the output might be a decoy in the ring signature. Their is no way for an attacker to know if you really sent a transaction, or if your output is being used in somebody else's transaction. They don't know if you have the money of if it was already spent.

looks like the first transaction someone makes is always identifiable if the decoys are picked from previous transactions

[@DecentralizedThought]

I don't think the decoy transactions are from the wallets previous transactions. I believe they are outputs randomly selected from the entire block chain.

[@danielokeefe1138]

They decoys are signatures from random past transaction outputs from the blockchain. Not picked from previous transactions of the user

[@user-ui4fn6fj3p]

3 years late to this but what's stopping someone from checking the 11 outputs against every single output in the history of the blockchain and determining which 10 match previous outputs and which one doesn't?

Bitcoin have transparent ledger. Monero have non transparent ledger.
