Of course... that explains everything! *facepalm*

he did he gave an explanation of chandran sigs and agreed it was flawed due to a security problem and how he cant link them because they are unlinkable/traecable

I just explained how it's not fishy. Reread that quote please.

Hondo say something on this so we all know where we are please
People hard money is been stolen if they believe LongAndShort fudster.

Please update on stealthsend hondo.

How is it NOT fishy?

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.

How can you all deny the facts..its not going to happen stealthsend is your only hope and its not going to happen when its meant to and how its meant to if at all
how can you justify ignoring it

This is a fact

 

This user is currently ignored

How is that fishy? The shadow community isn't attacking you and doesnt feel any desire to do so.

And for the record, it's Shadowcash.
