All time high guys!!

every time there's a "doubter's dip" I pee a little!

[EmilioMann]

looks like a motherfucker is holding the price below 13k.
when it is at 12900, a small dump happens

[Propulsion]

Can someone explain Chandran Signature's to me please? Bonus points if it's technical.

1. EmilioMann - Bobsurplus is still way into this coin, unlike what your post earlier said.
2. BTCwriter - Quit the whole posting in BTCD and SuperNET thread telling them that they are spamming this thread.  Unless you have facts you are not helping the situation.

I hold this coin and will continue to do so but at the same time both of you make me cringe with your constant cheerleading, circle jerking, reposting, and more.

To sum it up EmilioMann and BTCwriter are the two girls and this thread is becoming their cup.

Here is more than you can handle from the paper at UCLA http://www.cs.ucla.edu/~sahai/work/web/2007%20Publications/ICALP_Chandran2007.pdf

The only one who could talk about chandran signatures is Hondo, since is studying for months and have never been implemented before in cryptocoins.
I talked to him today by pm, and he was very excited and said that this will revolutionize cryptonote especially after the security problems that emerged in the coins that use ring signatures (monero, boolberry)
In whitepaper brief he says something about chandran signatures https://dl.dropboxusercontent.com/u/9200425/xst/Stealthsend_Whitepaper_brief0914.pdf
Sorry for my English

A new arrival in the arena of anonymous crypto-currences, StealthCoin (XST), promises to add ring signatures to the Bitcoin codebase with StealthSend, which is still in development. According to the StealthSend whitepaper (https://www.dropbox.com/s/do4urdefwoungjz/Stealthsend-Whitepaper-Brief-201409.pdf?dl=0), StealthSend transactions using ring signatures of 100 keys will only require about one third the space of similar CryptoNote transactions, but give the same level of privacy protection. This savings is achieved through the use of the use of so-called “Chandran Signatures”, and innovations related to the selection of the keys used for the ring signatures. In StealthSend, key selection is based on four numbers: two random numbers (called “nonces”), one number that reduces the difficulty of selecting the keys by specifying a subset of all possible keys, and one number to specify the size of the ring. Thus, the nonce key selection specifies any set of randomly selected keys using only 32 bytes of storage.Applied to CryptoNotes, the nonce key selection proposed for StealthSend would lead to a space savings of about 30% for future transactions.

fuck you mother fucker.
I never spoke to you and also not given you confidence to speak that way to me.
From this moment you will be ignored otário filho duma puta
Back to your scam seu viado zéruela trouxa deve ter crescido sendo comido pela vizinhança toda sua boneca

Get ready for 20k soon!

Alright so the name "Chandran Signatures" is from the person who proposed it; Nishanth Chandran?

And really it is actually Sublinear Signatures that are being proposed to be added which seems to be a variation of the ring-signatures used by cryptonote currencies. (Hypothesizing here, correct me if I'm wrong)

Now it also appears that the only difference between sublinear ring signatures and non-sublinear ring signatures is the lack of bloat from the former.

If I'm correct with the above, I would assume that this implementation of ring signatures would still be vulnerable to the same exploit used in regular cryptonote currencies. (if BCX has actually found an exploit)

Anyway, interesting stuff. Thanks for the links. I'll keep an eye on this.

YAWN
Something something about confidence to speak that way to you, yes, you sound like a retard and I am tired of your shit.
Please ignore me and continue on speaking in a language other than English, because you fucking suck at it.
Back to my scam?  So you basically called Stealthcoin a scam?

Hondo seems to be creating something new, don't just implementing chandran signatures in source code of the regular cryptonotes

Now it also appears that the only difference between sublinear ring signatures and non-sublinear ring signatures is the lack of bloat from the former.

A dev (I think he's a Monero guy) said that Chandran Signatures are actually larger and slower. So I asked him about it given the StealthSend white paper says they're smaller and gave examples of how they would be smaller.  He explained that yes, with the examples given in the white paper, they would be smaller than CN, but when you have a lot less sigs in the mix, it would actually end up being larger than the CN sigs. He also showed me a Monero transaction that was very small, < 1k in size.

He also said that Chandran Signatures have the same issue as the CN ones that were outlined in a whitepaper about flaws in Monero.

this guy who you spoke didn't know what is chandran signatures until a few days ago.
monero is a copy&paste of bytecoin
