## What it is
ViaBTC Exchange Server is a high-performance cryptocurrency exchange trading backend written in C, capable of processing up to 10,000 trades per second. It consists of a matchengine, market data services, HTTP and websocket access servers, and an alert center, using MySQL, Redis, and Kafka as supporting infrastructure.

## Use cases
- run a cryptocurrency exchange backend
- match orders at high throughput
- push real-time market and user data over websocket
- generate k-line candlestick market data
- store and query trade and balance history
- build a self-hosted digital asset trading platform

## When to choose
- you need a battle-tested, high-speed order matching engine
- you are building a crypto exchange and want full control of the backend
- you need real-time websocket push for market and user data
- you can operate the required MySQL, Redis, and Kafka infrastructure

## When to avoid
- you need a turnkey exchange with frontend and admin UI included
- you cannot maintain C code or complex multi-service deployments
- you target platforms other than Ubuntu 14.04/16.04 without testing
- you need frequent updates or active community support
