How mining works on XPrivFi
Mining in XPrivFi is not a computational arms race. It is an equal-chance, round-based mechanism where hardware advantage does not matter.
Equal-chance PoW (iPoW)
At the protocol level (Layer-1), XPrivFi uses interactive Proof-of-Work (iPoW) secured by the RandomHash function and CP-Diff v1.0 difficulty targeting. This produces blocks at an average of ~6 minutes.
However, unlike traditional mining, XPrivFi does not make individuals compete with GPUs or ASICs. Hardware size does not influence the chance of winning a round.
HexGrid: the Layer-2 mining game
Mining rewards are distributed through HexGrid, a browser-based game designed to make mining fair and accessible:
- 200–890 participants required per round (hard-coded).
- Every participant chooses a tile on the grid (visual only).
- All users perform equalized browser work — hardware differences do not matter.
- When the round ends, exactly one human is selected to receive the 1 XPF reward.
- The winning block is mined by the backend node using real PoW.
- The browser mining layer does not affect consensus.
Why equal-chance?
Traditional mining rewards the biggest machine. XPrivFi rewards participation — not hardware.
- Phone = Laptop = Supercomputer (same chance)
- No GPU/ASIC arms race
- No advantage from electricity budgets
- No hashpower monopolies
- Rounds grow anonymity sets (200–890)
Fees
Mining is free at launch. If XPF becomes listed on a DEX, an optional Layer-2 participation fee may be introduced. This fee:
- exists only on Layer-2 (HexGrid)
- does NOT affect supply or consensus
- is NOT required for protocol security
The Miner (UI) vs The Node (PoW)
The browser miner provides the user experience. The node provides real chain security.
- The node performs true RandomHash PoW.
- The browser performs only fairness work (not consensus-critical).
- The pool coordinates participants and enforces the 200–890 rule.
- Each round’s winner is determined without machine advantage.
