Bitcoin Private (BTCP) is an open-source, peer-to-peer cryptocurrency with the optional ability to keep the sender, receiver, and amount private in a given transaction. This is in contrast to many cryptocurrencies such as Bitcoin, which have a fully transparent transaction history.
Bitcoin Private gives users the option to generate either public or private addresses, redeemable for transactions to either address type. Private addresses work by using use Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge (zk-SNARKs). Evidence of ownership is provided without revealing which units are owned. This means that owners can redeem funds without any traceable history.
Bitcoin Private retained Zclassic's Equihash algorithm. Equihash is a memory-intensive proof of work mechanism, making it ASIC-resistant. This reduces centralization by incentivizing mining with accessible hardware. Bitcoin Gold also borrowed Equihash from Zcash.
Bitcoin Private is a merge fork of Bitcoin and Zclassic. Zclassic is a fork of Zcash, an implementation of the Zerocoin whitepaper. Zclassic was released in November 2016, by Rhett Creighton, a blockchain developer and minor Bitcoin core contributor in the San Francisco Bay Area. Creighton used the same code as Zcash, with a lack of a founders fee required to mine a valid block. This promotes a fair distribution, preventing centralized coin ownership and control. In December 2017, Creighton announced that he would be restarting Zclassic development after months of inactivity. The Zclassic team announced interest in creating a private Bitcoin fork days later. Bitcoin Private's fork snapshot occurred on 28 February 2018, and the mainnet was launched 3 days later.
