We do not plan any coins.
We plain a private payment mechanism for the servers that will utilize blockchain for valid reasons - we call it Community Vouchers. But they are not coins, they are service credits that cannot be created out of nothing (as coins) and cannot be sold - they can only be used to pay for the servers.

Whitepaper on that design will be published in early 2026.
