the security vulnerability with ZeroCoin found. Other Privacy Coins are also at risk. The developers initially want to spend but have no resources to fix the Problem. Do you prefer to work on your project for the future Sigma.

The Zcoin-Team discovered the so-called Exploit, so a security flaw in the Zerocoin Protocol. This allows a potential attacker to fake the Zero-Knowledge-Proofs (ZKP).
crypto-Token, use the Veil Protocol, the attacks it is vulnerable to at the time of the deactivation of zero coins. Currently, no date has been set for the shutdown.
At 9. April was made the XZC-Team on a number of irregularities in the Mining attentive and gave 100 out of Nothing-made Token. Immediately contact all of the Mining Pools, crypto exchanges, and other projects that use the Protocol to disable ZeroCoin. At the same time a study of the problem took place. Until the 19th century. April, you found the cause of the problem. Only at 24. April, however, the team of developers released a emergency Update.
the investigation could determine the Team that are not weak, the result of a coding error, but a cryptographic error in one of the ZKP. This vulnerability was evident since the introduction of the ZeroCoin Protocol.
The Problem with ZeroCoin
The ZeroCoin Protocol allows it to destroy a Token, without having the transaction history to prove. This works by creating a Zero-Knowledge-Proof. In this case, the Protocol is veiled, however, which Coins disappeared. In order to prevent, that users use the same ZKP to claim a new Token again, everyone gets ZeroCoin is a unique serial number.
However, the error allows an attacker to take advantage of individual Coins repeatedly. The attacker can now convert the currency to your liking. In addition, the Token can compromise the privacy of subsequent transactions. This Problem can be solved only by a new Privacy Protocol.
The company has spent the most part of the past year in order to replace ZeroCoin by Sigma. This is a precursor to the data protection Protocol of the next Generation of Lelantus, which will expand its functionality and data protection features during the Mining and output process.
It is not known what will happen with other crypto-currencies that use the ZeroCoin Protocol. However, they are still vulnerable to the attack, which is why Zcoin has the features of the above-mentioned cryptographic error not yet disclosed. This could potentially lead to malicious attacks on XZC and other projects that use the Protocol.
