Zclassic (ZCL)ZCL
A November 2016 fork of the Zcash code that removed the 20% founders' reward and the slow start, later the Zcash-side parent of Bitcoin Private.
The wiki's angle: Zclassic is the Zcash founders' reward argument turned into a coin. It kept Zcash's cryptography and trusted setup and removed only the money that went to the company, which is the same funding fight that later split Bitcoin Cash.[1][4]
Announcement
The Bitcointalk announcement, opened on 6 November 2016, describes Zclassic as “a fork of Zcash 1.0.1 with minimal changes except for 2 major things”: the 20% founders' reward is removed and the slow start is removed, so blocks start at 12.5 ZCL[1]. It keeps Equihash, a four-year halving, a 21 million supply and Digishield difficulty adjustment[1].
Trusted setup
The announcement says Zclassic “uses the exact same trusted parameters Zcash uses”, explaining that anyone with the destroyed key could mint unlimited coins and that Zcash's ceremony split that key among six people[1]. It says reusing them “is also what Peter Todd suggests”, linking a Reddit thread on the subject[1].
Bitcoin Private
In 2018 Zclassic became one parent of Bitcoin Private, which combined a snapshot of Zclassic with a snapshot of Bitcoin[2]. The Bitcoin Private README calls it “a fork of Zclassic, merging in a snapshotted UTXO set of Bitcoin”[2]. The current Zclassic README, version 2.1.2-beta6, describes it as “Based on Bitcoin's code and derived from Zcash”[3]. Its current market data and node count are unknown in this wiki[3].
