Let me briefly talk about the #celestia project
1) Celestia is like a super large cloud storage space, specially used to store data of various applications. This space is particularly safe and can store a lot of data, so it won't fill up easily.
Now, there are many friends who want to store things in this space, but they don’t want to build a storage space themselves because it is too troublesome. Therefore, they chose to use Celestia, a large warehouse.
In order to use this warehouse, they need to pay some fees, just like we need to pay to rent cloud disk space. This fee is paid with Celestia tokens.
Also, if someone wants to be an administrator in this big warehouse and help maintain and protect the data, they need to put some tokens there as a deposit. This way, if they do something bad, the tokens will be deducted.
In general, Celestia is a super large and secure data storage space that allows everyone to store and use data conveniently without having to build it from scratch. Its tokens are used to pay usage fees and as deposits.
