Zclassic is a cryptocurrency with the optional ability to keep the sender, receiver, and amount private in a given transaction. Forked from Zcash, Zclassic uses the same source code, but has no founder's reward or pre-mine.[1]


Zclassic's added privacy comes from its ability to generate of a shielded address (z-address) – an alternative to the standard transparent address (t-address). Both address types are redeemable for transactions to either address type. Z-addresses use Zero-Knowledge Succinct Non-Interactive Argument of Knowledges (zk-SNARKs) to keep transactions private. These proofs provide evidence of ownership without revealing which units are owned.[2]


Zclassic started as a fork of Zcash on November 5, 2016, eight days after Zcash's own release. At launch, the only differences between them was that Zclassic waived the 20% miners fee for its founders, and supply was not artificially limited at its creation (i.e. no "slow start" for blocks). Zclassic kept the same defining parameters of Zcash, such as the use of the ASIC-resistant equihash timestamping scheme, and a total supply of 21 million units.[3] Zclassic has been developed in parallel with Zcash up to release 1.0.10-1.[4]

Zclassic Forks[edit]


ZenCash is a fork of Zclassic that occurred on block 110,000 on May 23, 2017.[5]

Bitcoin Private[edit]

Bitcoin Private (BTCP) is a fork of Bitcoin and Zclassic that occurred on Bitcoin block 511346 and Zclassic block 272991.[6][7] The main difference between Bitcoin Private and other Bitcoin forks is its use of zk-SNARKs for added privacy. Bitcoin Private retained Zclassic's Equihash algorithm,[7] which was also borrowed from Zcash in the case of Bitcoin Gold.[8][9]
