Bitcoin Private is a Bitcoin fork merged with ZClassic designed to enhance the confidentiality of on-chain transaction metadata.
Bitcoin Private (BTCP) was launched to provide a fork that fixed perceived anonymity weaknesses in Bitcoin's blockchain, a similar motivation that created other privacy-focused projects like Monero and Grin. BTCP is unique in that it fork-merges Bitcoin with Zclassic in an attempt to achieve lower fees, faster transaction throughput, and heightened on-chain confidentiality than Bitcoin. As is common among Bitcoin forks, BTCP also claims to fulfill certain aspects of Satoshi's "vision" for the original Bitcoin codebase.
