ZEN, a derivative of ZClassic, focuses on "private and reliable transactions, communications, and publishing." They claim to be the "world's first private, distributed, and reliable platform" in those areas.
Secure nodes, distributed globally, provide a resilient network for fully encrypted activity.
The project also retains 8.5% of each block reward for operational costs such as infrastructure, development, and marketing. Similarly, 3.5% is distributed to secure Zencash node operators to incentivize network growth and community involvement.
Zen's private messaging capabilities, integrated with IPFS, allow for communication of any size or type of information across a peer-to-peer hypermedia protocol.
