Blockchain technologies are gradually making their way into various (still relatively few) business areas, including logistics, insurance, finance, etc.
There is another interesting direction - these are blockchain games https://kevurugames.com/blockchain-game-development/ which began to develop actively in 2021. They are based on blockchain technologies, using elements of cryptography. Cryptocurrency in such games is the main in-game tool.
Basic blockchain infrastructure
With the basis of your project, you need to decide on the shore, when the question of creating a game arose. The main thing here is long-term planning. Preferably - immediately for 2-3 years, because we are talking about creating a real project that will need to be developed and expanded. If after a while you decide to change the platform, then very big problems will arise. This is not at all the same as switching from one bank to another for ordinary business (and even here there are difficulties).
In addition to the blockchain platform, before working on a game project, you need to decide on the wallet that will be used. The main thing you need to know is that everyone has a couple of tens of millions of users and a convenient UX / UI. You can work with almost all blockchains.
After the blockchain and wallet options are selected, they need to be linked into a single system. In addition to the already named elements, it should include core gameplay and a server part that will ensure the operation of the entire project.
We are talking about the possibility of buying cryptocurrencies inside the game for fiat, that is, currencies familiar to everyone like the euro or the dollar, without leaving the game. There are not so few projects, they can be divided into those that have access to the US market and those that do not have such access.
