Zcash discloses a flaw, first discovered in-house last March and fixed in October, that may have allowed “infinite” counterfeiting
http://bitsonline.com/ ... via @wpeaster @whalepanda : People should stick to their field of expertise. US based centralized altcoin with optional privacy what 97% of the people don't use and that has been consistently losing value in the last 2 years with potentially compromised key ceremony. http://twitter.com/... Jessy Irwin / @jessysaurusrex : This is an exceptional example of using internal resources to find serious bugs and coordinating vulnerability disclosure, aka #vulnlifegoals. Great work, @zcashco, @zooko et al: Zcash Counterfeiting Vulnerability Successfully Remediated http://z.cash/... Tony Arcieri / @bascule : Challenge to all zero-knowledge cryptocurrencies: always be able to prove the total size of the money supply in zero knowledge http://twitter.com/... Rocco / @obstropolos : “This vulnerability is so subtle that it evaded years of analysis by expert cryptographers focused on zero-knowledge proving systems and zk-SNARKs.” Wild. Kudos to @zcashco @zooko and all involved for the control and removal of this vulnerability. http://z.cash/... Peter Todd / @peterktodd : (fixed) Zcash counterfeiting vulnerability: http://z.cash/... “This vulnerability is so subtle that it evaded years of analysis by expert cryptographers focused on zero-knowledge proving systems” Reality is bleeding edge crypto is risky; second inflation bug they've had. Robert Hackett / @rhhackett : Big: Zcash discloses vulnerability that could have allowed “infinite counterfeit” cryptocurrency. Some projects appear still to be vulnerable. http://fortune.com/...
