# Mining Machine & Token Reward

NFT Mining page allows you to find four Mining Machines, but outside of promotional events, you need to spend OVO Tokens to unlock them. When performing NFT Mining, users insert NFT content with Mining Power into the Mining Machines to dig out OVO Tokens. NFT Mining in OVO is mainly composed of Mining Machines, Batteries, and NFT content for mining, and their relationship is shown in the following diagram.



_\*Note: The official version should be based on the content announced by OVO._

One important point to note is that the battery of the Mining Machine has a degradation model, so the maximum capacity of the battery decreases each time it is charged (recharged with ST). If the maximum capacity of the battery becomes zero after repeated degradation, the Mining Machine will be locked again, but it can be reset by consuming a specified amount of OVO Tokens.

Additionally, OVO's NFT Mining does not introduce any conditions, such as locking the produced OVO Tokens, and miners can claim Tokens they have earned through mining at any time. The Token rewards that miners can claim are determined by the following formula.
