# Introduction

**Error** is an underground mining simulation game where players build their own digital mining rigs, upgrade workers, and extract valuable resources - all powered by BNB onchain.

Unlike traditional idle games where you simply hold a token, in **Error** you *earn* $ERROR by actively mining, upgrading, and managing your operation. Every block rewards those contributing to the network’s total mining power - just like real miners competing for block rewards.

Your setup, tools, and upgrades determine your share of emissions - and as competition increases, only the strongest rigs will thrive.
