Asset Management Service (AMS)

AMS is an alternative service to Blockchain's Transaction/Account balance service, but it's centralized database(MySQL8).

We used to use blockchain as the storage and management of user assets.Now we have 4 millions+ registered users, there are some problems to suit our future needs.

DB
- MySQL8 JSON for JSON data.
API
- Sanic for asynchronous api services.
- encode databases[aiomysql] for asynchronous MySQL support.
Reverse Proxy and load balancer
- Traefik with Docker for automatically and dynamically proxy and load balancer.

Why not blockchain?

Expensive

With more users, the monthly expenses are getting higher and higher.

Our blockchain base consumes a lot of disk and memory resources, it's a high monthly cost bill from AMS.

This is the main reason.

Slow

Broadcast a transaction to blockchain is very slow. Our users need to wait minutes to confirm their asset transfer is done.

Why not PostgreSQL or MongoDB?

Expensive, compared with AWS MySQL by our boss and OPs :|
