BitZeny (ZNY) is a decentralized cryptocurrency based on Bitcoin, originally developed by a Japanese engineer. It is designed to be mineable using CPUs equipped in ordinary PCs by adopting the Yescrypt hashing algorithm and the DarkGravityWave3 difficulty controlling mechanism.

|Halving||Every 500,000 blocks|
The development was originally started by a Japanese engineer in November 2014 (reference in Japanese: ). The original developer had been offline since only a month after it was released, but came back online on December 2017. While the original developer had kept silent, voluntary people gathered as a community to work on adapting the wallet and miner programs to newer versions of bitcoin-based source codes, building an online forum, and advertising the coin.
The value has been less than 0.1 USD/ZNY since its release, but it increased to around 0.2 USD/ZNY on December 2017 with the maximum of 0.43 USD/ZNY on December 6th, 2017.
Yescript is a hashing algorithm built with an aim to be GPU-unfriendly by design. The basic idea is to issue many random accesses to the memory so that SIMD processors such as GPUs cannot calculate hashes efficiently. A GPU implementation to calculate Yescript is reported to be 7.3X slower than a CPU implementation (700 hashes/s with AMD Radeon R9 280X vs. 5.1K hashes/s with Core i7 5820K). This GPU-unfriendliness gives BitZeny a unique characteristics; it is one of a few alt-coins that can be mined a reasonable amount by CPUs. It is suitable for the one-CPU-one-vote described by Satoshi Nakamoto in his whitepaper.
