2. blockchain is a decentralized system. However, e to the limited data that blocks in blockchain can store, the form of blockchain + database (cloud storage, distributed database, etc.) is widely used in blockchain projects
on this premise, there are many databases to choose from, such as lightweight SQLite, which can be used as the basic data storage support of app, MySQL and Oracle which need more data performance support, and various key value databases, such as redis and Memcache, can also be used as cache support in project cache service, Of course, a variety of distributed database systems are also a direction of development.

for blockchain projects, you can also find blockchain companies with better strength in the blockchain instry to discuss further cooperation. Maybe you can find some blockchain projects.
