Citigroup<\/strong> taraf\u0131ndan yay\u0131mlanan yeni rapor, kuantum<\/a> hesaplama teknolojilerindeki h\u0131zlanman\u0131n kripto<\/strong> piyasas\u0131 i\u00e7in beklenenden daha erken bir g\u00fcvenlik tehdidi olu\u015fturabilece\u011fini ortaya koydu.

Raporda dikkat \u00e7eken nokta yaln\u0131zca teorik sald\u0131r\u0131 ihtimali de\u011fil. Citi analistleri, teknoloji taraf\u0131ndaki ilerlemenin art\u0131k yat\u0131r\u0131mc\u0131lar\u0131n g\u00f6z ard\u0131 edemeyece\u011fi bir h\u0131zda ilerledi\u011fini d\u00fc\u015f\u00fcn\u00fcyor.<\/p>\n

Bitcoin \u0130\u00e7in En Kritik Risk: A\u00e7\u0131k Anahtarlar<\/h2>\n

Citi analisti Alex Saunders taraf\u0131ndan haz\u0131rlanan rapora g\u00f6re kuantum bilgisayarlar gelecekte Bitcoin ve Ethereum gibi a\u011flarda kullan\u0131lan ECDSA tabanl\u0131 a\u00e7\u0131k anahtarl\u0131 \u015fifreleme sistemlerini hedef alabilir.<\/p>\n

Teorik senaryoda yeterince g\u00fc\u00e7l\u00fc bir kuantum bilgisayar, a\u00e7\u0131k anahtarlardan \u00f6zel anahtar t\u00fcretebilir. Bu da sald\u0131rganlar\u0131n sahte i\u015flemler \u00fcretmesine, c\u00fczdan eri\u015fimi sa\u011flamas\u0131na ve varl\u0131k \u00e7almas\u0131na imkan verebilir.<\/p>\n

Bankan\u0131n tahminine g\u00f6re \u015fu anda 6,5 ila 6,9 milyon BTC kuantum riski alt\u0131nda bulunuyor. Bunun nedeni, ilgili c\u00fczdanlar\u0131n a\u00e7\u0131k anahtarlar\u0131n\u0131n zincir \u00fczerinde daha \u00f6nce g\u00f6r\u00fcn\u00fcr hale gelmi\u015f olmas\u0131.<\/p>\n

Bu miktar dola\u015f\u0131mdaki Bitcoin arz\u0131n\u0131n yakla\u015f\u0131k \u00fc\u00e7te birine kar\u015f\u0131l\u0131k geliyor. G\u00fcncel fiyatlarla hesapland\u0131\u011f\u0131nda risk alt\u0131ndaki varl\u0131klar\u0131n de\u011feri yakla\u015f\u0131k 450 milyar dolar seviyesine ula\u015f\u0131yor.<\/p>\n

Raporda Satoshi Nakamoto\u2019ya ait oldu\u011fu d\u00fc\u015f\u00fcn\u00fclen eski P2PK c\u00fczdanlar\u0131n\u0131n da potansiyel risk grubunda yer ald\u0131\u011f\u0131 belirtildi.<\/p>\n

Citi: Bitcoin Daha Yava\u015f Tepki Verebilir<\/h2>\n

Rapora g\u00f6re Bitcoin\u2019in en zay\u0131f noktalar\u0131ndan biri teknik de\u011fil, y\u00f6neti\u015fim yap\u0131s\u0131.<\/p>\n

Citi analistleri, Bitcoin a\u011f\u0131ndaki protokol g\u00fcncellemelerinin yava\u015f ilerledi\u011fini ve bunun kuantum tehditlerine kar\u015f\u0131 h\u0131zl\u0131 adaptasyonu zorla\u015ft\u0131rabilece\u011fini d\u00fc\u015f\u00fcn\u00fcyor. Ethereum gibi proof-of-stake a\u011flar\u0131n\u0131n ise daha esnek y\u00fckseltme mekanizmas\u0131na sahip olmas\u0131 nedeniyle daha h\u0131zl\u0131 reaksiyon verebilece\u011fi belirtiliyor.<\/p>\n

Ancak rapor Ethereum taraf\u0131nda da risk olmad\u0131\u011f\u0131 anlam\u0131na gelmiyor. Citi, geli\u015fmi\u015f kuantum sistemlerinin do\u011frulay\u0131c\u0131 anahtarlar\u0131n\u0131 hedef alabilece\u011fi ve a\u011f operasyonlar\u0131n\u0131 bozabilece\u011fi konusunda da uyar\u0131yor.<\/p>\n

\u201c\u015eimdi Topla, Sonra \u00c7\u00f6z\u201d Riski B\u00fcy\u00fcyor<\/h2>\n

Raporda dikkat \u00e7ekilen bir di\u011fer senaryo ise \u201charvest now, decrypt later\u201d modeli oldu.<\/p>\n

Bu yakla\u015f\u0131mda sald\u0131rganlar, bug\u00fcn \u015fifrelenmi\u015f verileri topluyor ve kuantum teknolojisi yeterince geli\u015fti\u011finde bu verileri \u00e7\u00f6zmeyi hedefliyor. Citi\u2019ye g\u00f6re kuantum bilgisayarlar\u0131n mevcut h\u0131zlanma trendi, bu riskin daha yak\u0131ndan takip edilmesini gerektiriyor.<\/p>\n

Bankaya g\u00f6re b\u00fcy\u00fck \u00f6l\u00e7ekli kuantum sald\u0131r\u0131lar\u0131 h\u00e2l\u00e2 orta vadeli bir tehdit olarak g\u00f6r\u00fcl\u00fcyor. Ancak teknoloji taraf\u0131ndaki ilerleme, beklenen zaman \u00e7izelgesini giderek \u00f6ne \u00e7ekiyor.<\/p>\n

Kripto Sekt\u00f6r\u00fc \u00c7\u00f6z\u00fcm Ar\u0131yor<\/h2>\n

Citi, risklere ra\u011fmen kripto sekt\u00f6r\u00fcn\u00fcn tamamen savunmas\u0131z olmad\u0131\u011f\u0131n\u0131 d\u00fc\u015f\u00fcn\u00fcyor.<\/p>\n

Raporda kuantum sonras\u0131 kriptografi \u00e7\u00f6z\u00fcmleri, yeni protokol tasar\u0131mlar\u0131 ve Bitcoin i\u00e7in \u00f6nerilen BIP-360 ile BIP-361 y\u00fckseltmeleri yak\u0131ndan izlenmesi gereken geli\u015fmeler aras\u0131nda g\u00f6sterildi.<\/p>\n

\u015eimdilik tehdit do\u011frudan fiyatlanan bir risk de\u011fil. Ancak Wall Street taraf\u0131nda kuantum hesaplama art\u0131k yaln\u0131zca teorik bir teknoloji ba\u015fl\u0131\u011f\u0131 olarak g\u00f6r\u00fclm\u00fcyor.<\/p>\n
