Hey miners!

In the previous article, we understood how mining works. Now, it’s time to take a look at the maintenance, a system which should be implemented in the next 20 days.

First, keep in mind that those mechanisms are still under development (meaning that final numbers/concepts may slightly change).

Second, the global maintenance aspect was introduced in order to:

  • Make the game more exciting! Instead of simply placing your NFTs and just wait (passive mining), you will now have to regularly inspect your equipment and verify that everything is fine (active mining).
  • Offer bigger rewards to the active miners! The more active you will be, the more you will earn!
  • Better simulate real mining activities. In reality, when you use equipment, it wears out, gets damaged and sometimes even breaks.
  • Strengthen the tokenomics of the game. This new mechanic will introduce new incentives to spend the different tokens while stimulating the apparition of new use cases.
  • Limit the use of scripts, bots or other cheating tools. The introduction of those new concepts will make it very hard for cheaters to mine (thus favorizing honest miners)

Concretely, what will be added?

First, the mining process will be developed:

  • When setting up a new mine (i.e. choosing your land, the constructions and the actives), the first 2 mining rounds will be less profitable. You will earn 50% then 75% of what you should normally earn. Why? To simulate real life logistic, preparation and initial set-up.
  • It will now take 20 minutes to start a new mine or stop a running one. Why? To simulate operation traveling from your base (called HQ) to your land. This feature will also be later used on the metaverse map.

In summary: starting and stopping operations will now cost you time and will also negatively affect your yield. We then strongly advise you to carefully evaluate your options and design the best mining strategies prior making any decisions.

Second, all your assets (actives, constructions, lands) will now be affected by mining:

  • Each asset will have its own durability.
  • While mining, every asset will have a chance to get damaged (called partial break). This probability will depend on the rarity of the asset with rarest assets having the lowest chances of getting damaged (Common 9% ; Ultimate 7%).
  • Partial break on a particular asset will decrease its durability. Each time that a break will occur, the NFT will lose between 8–12% of its durability. Also, the more damages your asset cumulates, the less it should be affected by the following breaks.
  • Although, the productivity of an asset is dependant on its durability with lower durability meaning lower yield. For instance, an NFT with a durability at 50% will mine twice less than the same NFT having its durability at 100%.

In summary: while mining, each NFT will have a probability to partially break meaning, suffering from a production decrease (RESM and NFTM reduced). Those changes will make it essential for you to regularly inspect your setup and take care of your assets!

Third, to take care of your assets, you will need to repair them:

  • The rarer the item, the more expensive the repairs will be.
  • You will have the choice between 2 types of repairs : In your base or On site
  • In your base: You will need to stop all the operations in order to get all your assets returned to your HQ. Each 1% of repair will take 10sec (with a max. amount of time capped at 16min30sec). This type or repair will only cost you time (first to stop the operations, second, to repair your NFTs and third to properly restart your operations ; don’t forget the first part of this article about starting your mine).
  • On site: No need to stop the operations! But this type of repairs will take some planification and will cost you some resources.
  • You will need first to set up a given amount of resources that you want to send on site knowing that, each type of asset will be repairable using a unique token. Actium for Actives, Constructium for Constructions and Minium for Lands.
  • Second, sending those resources will cost you Fusium (to hold and transport the resources on site). Simply put, the amount of fusium required = 1% of the total amount of resources sent. E.g. If you send 10000 resources, it will cost you 100 Fusium.
  • On site, for each NFT, the repair costs will mostly depend on the amount of damage accumulated along with the rarity of the card. Other unique parameters will also be included in this equation such as the size (for the Lands and Constructions) or energy (for Actives).

In summary: Before starting a mine, think in advance how you will repair your equipment. In your base? You will need to stop the operations and you will lose time… On site? No time wasted but it will cost you some resources and you will need first to planify and send the right amount of resources that you might need.

Finally, a last rule will be introduced to disadvantage the biggest players :

  • Above 4 cards placed on a land, each additional card will increase by 12.5% the global probability of partial break (probability spread among all the NFTs on the land). In brief : the bigger your setup, the higher are the probabilities to see partial breaks. This rule was introduced to prevent big players from accumulating too many resources.

And… that’s it! But don’t forget that this system is still under development. Also, rest assured that, at NBM, we constantly do our best to develop a game that will be fair, realistic and fun to play! We hope to see you in the next article where we will tackle the Level up system.
