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.

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.

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

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

• API
  • High availability
  • Idempotent
  • High concurrency
  • Preventing injection attacks
  • ~0 downtime
  • Microservices
  • No ORM
• DB
  • High concurrency
  • Transaction
  • JSON support
  • Split tables automatically by datetime or mod or both
• Asset
  • Validate Account and Transaction by customized hash
  • Single and bulk transactions transfer
  • Send warning messages to telegram group
