PoolServerJ

PoolServerJ is a pure java implementation of a Bitcoin mining pool server. It’s functionally very similar to pushpoold. Although there are some differences it is capable of being swapped over with pushpoold without any config changes.

Features

• Work caching – caches work from bitcoind to handle short term spikes in requests
• DoS resilience with QoS support to ensure workers who’ve submitted valid work are serviced with priority
• Capable of pulling work from multiple bitcoin daemons to get around the getwork bottleneck and also to provide some redundancy
• Notify of block change via HTTP to a user configurable URL to support event triggered share processing
• Cached database handling (optional) to reduce round trips.
• Supports Mysql, Postgresql, sqlite3 (JDBC based so others can be added easily – currently only tested on mysql)
• Runs as a Windows service
• Longpolling support
• Integrated block monitoring using all available bitcoin daemon work sources
• Dump shares to Database, log file or stdout
• Safe restart – shares issued to client are dumped to file on shutdown and reloaded on startup so your miners won’t get stale shares if you restart a live server
• Only dependency is a Java 6+ JDK.
