In-game currency: inflation and security (and limited items)

Using blockchain technology, games can create currencies with non-fungible tokens. What that means is that each gold coin in the world only exists once, and players are unable to generate currency out of thin air.

It is important to note that this is not the same as having a marketplace to exchange game-coins for real currency. It just means that games can implement a system in which each coin dropped by a mob can only be dropped again after it has been spent by the players which returns it to the "bank" of the game.

So imagine a game in which 50% of the available gold is always kept in the server bank, and each time players start to farm (and the bank's balance falls under 50%) the amount of gold mobs drop will gradually start decreasing and NPC prices go up. And as players spend money (putting the balance above 50%) the prices gradually fall and farming rewards start to go up.

This way you can easily create an economy in which there is no inflation, since the amount of gold in the world is always kept steady.

There are some balancing issues with that, of course, like players stopping to play the game while holding large amounts of gold, but that can also be solved easily by taking a % of the player's gold out of his balance each month (especially on deactivated accounts that aren't paying a subscription).

This also increases security: a hacker can't magically increase his balance without taking away balance from other wallets.

Similar approaches can be used for resources: as players farm the world, resources disappear to generate scarcity. Once the resources are used up, they return to world drops and gathering spots. [have to write this article and connect link here]
