Satoshi Nakamoto Ocak 2009’da blokzincir teknolojisi ile beraber kriptopara kavramını ortaya atmış ve ilk kriptopara uygulaması olan Bitcoin’i yayınlamıştır [1]. Uzun yıllar boyunca Bitcoin açık anahtarlı adresleri kullandığı için anonimliği tamamıyla sağladığı düşünülmüştür. Ancak bu adresler herkese açık bir kayıt defterinde tutulduğundan dolayı Bitcoin anonim değildir. Herhangi bir Bitcoin adresinden yola çıkılarak o adresin tüm işlem geçmişini tespit etmek mümkündür. Bu nedenle zamanla anonim kriptoparlar yayınlanmıştır. Anonim kriptoparaların teoride matematiksel olarak tamamıyla anonim olduğunı belirtilir, ancak çeşitli sebeplerden dolayı teoride anonimliği yeteri kadar sağlayamazlar. Bu makalede Zcash, Dash ve Monero anonim kriptoparalarının gerçekten de pratikte iddia edildikleri kadar anonim olup olmadığını tespit etmek amacıyla korelasyon tabanlı mahremiyet analizleri yapılmıştır. Bu makaleyle beraber ilk defa Dash ve Monero anonim kriptoparaları için korelasyon tabanlı mahremiyet analizi çalışması yapılmıştır, Zcash için daha önce yapılan bir çalışma bulunmaktadır [2]. Zcash’in korumalı işlemleri %84.4 ve Dash’in ÖzelGönderim ile alakalı işlemleri %49.304 oranında ilişkilendirilebilmiştir. Monero işlemlerinin adres ve miktarları tamamen gizli olduğu için korelasyon tabanlı mahremiyet analizi gerçekleştirilememiştir.
