Dear Miners,
we would like to announce the end of Zcash mining introductory period. It mainly means that the pool will start collecting a fee, effective from August 8. Just like with Bitcoin, the fee will be set to 2 percent of total mining income (including network fees). Thank you all for helping us with the infrastructure testing and ironing out some last bugs.
