Kritik A\u00e7\u0131k Nas\u0131l Ortaya \u00c7\u0131kt\u0131?<\/h2>\n

Sorun, Zcash’in gizlilik altyap\u0131s\u0131n\u0131n merkezinde yer alan Orchard isimli korumal\u0131 i\u015flem havuzunda tespit edildi.<\/p>\n

Orchard, kullan\u0131c\u0131lar\u0131n i\u015flemlerini s\u0131f\u0131r bilgi ispatlar\u0131 (zero-knowledge proofs) ile gizli \u015fekilde ger\u00e7ekle\u015ftirmesine imkan tan\u0131yor ve a\u011f\u0131n en \u00f6nemli bile\u015fenlerinden biri olarak g\u00f6r\u00fcl\u00fcyor.<\/p>\n

Ekip \u0130ki A\u015famal\u0131 Acil Plan Uygulad\u0131<\/h2>\n

Zcash Open Development Lab (ZODL) kurucusu Josh Swihart, ya\u015fanan s\u00fcrecin detaylar\u0131n\u0131 kamuoyuyla payla\u015ft\u0131.<\/p>\n

Swihart’a g\u00f6re ekip iki a\u015famal\u0131 bir acil m\u00fcdahale plan\u0131 uygulad\u0131.<\/p>\n

\u0130lk a\u015famada soft fork devreye al\u0131narak Orchard i\u015flemleri ge\u00e7ici olarak durduruldu. B\u00f6ylece a\u00e7\u0131\u011f\u0131n k\u00f6t\u00fc niyetli ki\u015filer taraf\u0131ndan kullan\u0131lmas\u0131n\u0131n \u00f6n\u00fcne ge\u00e7ilmesi hedeflendi.<\/p>\n

Bu s\u00fcre\u00e7te a\u00e7\u0131\u011f\u0131n t\u00fcm detaylar\u0131 kamuoyuna a\u00e7\u0131klanmad\u0131. Ama\u00e7, g\u00fcvenlik sorunu tamamen giderilmeden potansiyel sald\u0131rganlara bilgi verilmesini engellemekti.<\/p>\n

\u0130kinci a\u015famada ise 3 Haziran’da NU6.2 isimli hard fork g\u00fcncellemesi aktif edildi.<\/p>\n

Bu g\u00fcncelleme ile a\u00e7\u0131\u011f\u0131n kayna\u011f\u0131 ortadan kald\u0131r\u0131ld\u0131 ve Orchard i\u015flemleri yeniden kullan\u0131labilir hale getirildi.<\/p>\n

Madenciler ve Borsalar S\u00fcrece Dahil Oldu<\/h2>\n

Swihart, yaln\u0131zca geli\u015ftirici ekibin de\u011fil, a\u011f\u0131n \u00f6nemli payda\u015flar\u0131n\u0131n da s\u00fcre\u00e7te aktif rol ald\u0131\u011f\u0131n\u0131 belirtti. \u00d6zellikle ViaBTC ve Foundry madencilik havuzlar\u0131n\u0131n koordinasyon s\u00fcrecinde \u00f6nemli destek verdi\u011fi ifade edildi.<\/p>\n

Ayr\u0131ca baz\u0131 borsalar ve madencilik havuzlar\u0131, g\u00fcncellemenin g\u00fcvenli\u011fini do\u011frulamak i\u00e7in kod inceleme talebinde bulundu.<\/p>\n

ZODL ekibi bu taleplere do\u011frudan yan\u0131t vererek g\u00fcncelleme s\u00fcrecinin \u015feffaf ilerlemesini sa\u011flad\u0131.<\/p>\n

Arthur Hayes Pozisyonunu Kapatt\u0131<\/h2>\n

BitMEX kurucu orta\u011f\u0131 Arthur Hayes, g\u00fcvenlik a\u00e7\u0131\u011f\u0131n\u0131n duyurulmas\u0131n\u0131n ard\u0131ndan elindeki t\u00fcm ZEC pozisyonlar\u0131n\u0131 satt\u0131\u011f\u0131n\u0131 a\u00e7\u0131klad\u0131.<\/p>\n

\u00d6zellikle projenin en \u00f6nemli sat\u0131\u015f noktas\u0131 olan gizlilik teknolojisinin b\u00f6yle bir a\u00e7\u0131kla g\u00fcndeme gelmesi, piyasadaki endi\u015feleri art\u0131rd\u0131.<\/p>\n

ZEC Toparlanabilecek mi?<\/h2>\n

Ya\u015fanan sert sat\u0131\u015flara ra\u011fmen piyasa \u015fu an yeni bir denge aray\u0131\u015f\u0131nda.<\/p>\n

Fiyat 303 dolarl\u0131k dip seviyeden \u00f6nemli \u00f6l\u00e7\u00fcde toparlanm\u0131\u015f olsa da yat\u0131r\u0131mc\u0131 g\u00fcveninin tamamen geri d\u00f6nd\u00fc\u011f\u00fcn\u00fc s\u00f6ylemek i\u00e7in erken g\u00f6r\u00fcn\u00fcyor.<\/p>\n

Bununla birlikte ekip ya\u015fanan krizi f\u0131rsata \u00e7evirmeye \u00e7al\u0131\u015f\u0131yor.<\/p>\n

Josh Swihart, s\u00fcrecin ard\u0131ndan yapt\u0131klar\u0131 de\u011ferlendirmede yaln\u0131zca sorunu \u00e7\u00f6zmediklerini, ayn\u0131 zamanda a\u011f\u0131n acil durum prosed\u00fcrlerini test ettiklerini, ekosistem payda\u015flar\u0131yla ili\u015fkileri g\u00fc\u00e7lendirdiklerini ve topluluk olarak daha dayan\u0131kl\u0131 hale geldiklerini ifade etti.<\/p>\n
