CR Mining System

2 min readPage 2 of 4 in Proof of Play

Proof of Play rewards are powered by the CR Mining System.

Clash Rush doesn't mint CR whenever a player completes an activity. A fixed emission schedule decides how much CR is minted over time, and players compete through Proof of Play to mine a share of it.

How Mining Works

During the first emission era, covering the first two years, a fixed amount of CR is released into the Proof of Play reward pool every minute:

150 CR / minute

That rate doesn't change with the number of players, matches played or XP earned. Whether 100 players take part or 1,000,000, the emission stays the same, so as Clash Rush grows, mining becomes more competitive rather than more inflationary.

Players don't mine CR directly. They play, earn XP, level up and unlock Mystery Boxes, which give them a chance to mine a share of the available CR.

More players don't create more CR. They compete for the same emissions.

How Rewards Are Distributed

Mystery Boxes are how the Mining System distributes CR to players.

A Mystery Box doesn't guarantee CR. Each box holds a randomized selection of assets and rewards, and the chance of finding CR depends on the box's tier: higher tiers have a greater probability of containing CR. Players can improve their chances of higher-tier boxes through Mining Badges.

Mystery Boxes and Mining Badges are explained in detail on the following pages.

Halving

CR becomes progressively harder to mine. Every two years, the Proof of Play emission rate is cut in half.

The Mining System itself doesn't change: players keep earning XP, unlocking Mystery Boxes and competing for CR. There is simply less new CR available to mine.

Each halving reduces the new CR available through Proof of Play, making the remaining emissions increasingly scarce.

The Mining Loop

XP drives progression. Mystery Boxes provide mining opportunities. Mining Badges improve those opportunities. The emission schedule decides how much CR is available.

More participation never creates more CR. It creates more competition for the CR being emitted.
