Add protocol to supply ZN Coin mining.

I hope there will be a corresponding coin, such as ZN coin, to incentivize nodes involved in building sites or participating in caching. Additionally, a distributed DNS server can be set up, allowing site owners to spend ZN coin to purchase domain names through the protocol.
In my opinion, ZeroNet is the true Web3.

The issue names no files, tests, or entry points. Start by clarifying the proposed ZN Coin incentives, mining protocol, and distributed DNS requirements with maintainers; the work is not ready to implement until its scope and acceptance criteria are agreed.
