Zcash Company, behind the development of Zcash cryptocurrency, revealed the details of the vulnerability that allowed attackers to create an unlimited number of non-existent ZEC coins.

According to a company blog report, March 1, 2018, Zcash cryptographer Ariel Gabizon discovered a vulnerability in the zk-SNARKS protocol, which Zcash uses to hide balances and user data.

Cryptocurrency developers decided not to disclose the details of the problem by including a patch in the update of the Zcash Sapling protocol, which was activated in late October. And only now the project team has publicly disclosed the circumstances of the incident.

The vulnerability was specific to counterfeiting and did not affect user privacy in any way. Prior to its remediation, an attacker could have created fake Zcash without being detected. The counterfeiting vulnerability has been fully remediated in Zcash and no action is required by Zcash users.

Also, developers note that the detection of vulnerability required an advanced level of technical and cryptographic knowledge that few possess.

After the discovery of the vulnerability, Zcash Company took "exceptional measures" to minimize the possibility of its operation, and also notified other cryptocurrency teams using the zk-SNARKS protocol, including Horizen and Komodo, about its existence.

Startup BOLT Labs successfully closed a seed round of financing led by Dekrypt Capital and raised $ 1.5 million to develop privacy-oriented solutions in second-layer protocols like the Lightning Network.

The venture unit of Ripple (Xpring), Zcash Foundation, Lemniscap, Access Ventures, Kilowatt Capital and business angel Branson Bollinger also took part in the round.

Computer Science Ph. D. Ayo Akinele, the founder of BOLT Labs, intends to use the tools to create a fast, private and secure network of payment channels. As planned by Akiniele, the new protocol will be scalable and compatible with any cryptocurrency networks and solutions of the second layer.

For the first time, the BOLT technology was presented in a document published in 2016 by Matthew Green and Ian Myers, the founders of the Electric Coin Company. The main task was to create a scalable solution of the second layer, in which the complete privacy of users is activated by default.

Note, the concept of the future product BOLT Labs for the network ZCash should appear in the summer of 2019.
