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

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.

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.

Stealth is the new king!

CRYPTONOTE COINS ARE DEAD!!!

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.
