From the SDC thread

Before addressing the criticisms raised in this thread, I would like to express my sincere appreciation for these criticisms. Although some believe the manner in which they have been introduced may not be optimal to promote civil discourse, they are valuable criticisms nevertheless, and help to strengthen crypto-currencies in general. It is far better to address weaknesses in crypto systems during implementation than it is to address attacks after deployment.

Chandran signatures [1] make use of a common reference string. The common reference string generator (CRSGen) is a necessity for a model that does not require a random oracle, as described in [1]. CRSGen produces a string that is used as an input to a key generation function. The key generation function produces the user's public-private key pair. This key pair has specific properties in that it is a member of a particular mathematical group. In principle, key generation can be replaced by a cryptographic one-way function if the random oracle assumption is introduced.

Admittedly a more difficult issue to address is one of "unlinkability/untraceability", which boils down to the potential for a double spend. In short, Chandran signatures require the generation of a secret random parameter, g, that serves as an input to a "commitment" to a specific key in the key ring. This commitment basically identifies the public key from which the money is spent. The problem is that any number of g can be produced, creating the potential for any number of commitments to the specific public key.

In reality, this same issue exists with CryptoNote ring signatures except that the CryptoNote system incorporates a key image, I, into signing and verification, such that I can only ever be used once. A similar approach can be taken with Chandran signatures. As presented in [1], a key image I can be incorporated into Step 3 of signing and appended to the final signature. In addition to other parameters, Step 3 commits to the public keys of a subset of the ring. Just as with CryptoNote ring signatures, such a modification would commit to the key image and prevent its use for double-spends.

Think about it. No normal person would spend this much time doing this, unless they are getting paid. Even a person with no life would have gotten tired of posting at this point.....yet LongballsandShortdick is still here repeating the same things over and over again.

Keep screaming BUY everyone!!!! Theres no fresh BTC that will touch this,, and the only people who can move markets are gone, thats why You all are so positive yet the price keeps sinking... IF you all actually did have BTC FUNDS then you would be pumping this to save the coin.. But you cant cause real players are out counting their money and laughing at you bagholders

Dear Community,

I would like everyone apart from the Shadow community to stop trolling, fudding or attacking XST or other coins. If your opinions are true or not does not matter in this regard. Crypto as a whole one gets hurt by fud, and it has no use at all but to drive the price down and scare off new investors. Please be the wise guy and don't get involved with childish discussions that lead nowhere at all.

Opinions are just that, opinions and every free person in this world has the right to their own. Whether he is involved in another project, coin or organisation does not matter as these opinions are his own.

Your writing style is an exact replica of longandshort's. If you're going to pretend to be two people, try varying your styles so it's less obvious.

The only people with money to pump your coin back up have left you all holding the bags... Yet you think theyr is still a fighting chance...... So sad
