Nimiq Mining-Pool Server

This mining pool server combines resources of multiple clients mining on the Nimiq blockchain. Clients are independent network nodes and generate or validate blocks themselves to support decentralization. Details about the mining pool protocol can be found here. A mining pool client is implemented in Nimiq Core.

Operating a public mining-pool in the mainnet makes you responsible for other people's money. Test your pool setup in the testnet first!

Architecture

The pool server consists of three parts which communicate through a common MySQL-compatible database (schema see sql/create.sql)

  • The pool server interacts with clients and verifies their shares. There can be multiple pool server instances.
  • The pool service computes client rewards using a PPLNS reward system.
  • The pool payout processes automatic payouts above a certain user balance and payout requests.

While the server(s) and the service are designed to run continuously, the pool payout has to be executed whenever a payout is desired.

Run

Run node index.js --config=[CONFIG_FILE]. See [server|service|payout].sample.conf for sample configuration files and clarifications.
