Electrum server
Python Shell
Branch: master

Electrum-server for the Electrum client

  • Author: Thomas Voegtlin (ThomasV on the bitcointalk forum)
  • Language: Python


  • The server indexes UTXOs by address, in a Patricia tree structure described by Alan Reiner (see the 'ultimate blockchain compression' thread in the Bitcointalk forum)

  • The server requires bitcoind, leveldb and plyvel

  • The server code is open source. Anyone can run a server, removing single points of failure concerns.

  • The server knows which set of Bitcoin addresses belong to the same wallet, which might raise concerns about anonymity. However, it should be possible to write clients capable of using several servers.


  1. To install and run a server, see INSTALL. For greater detail on the installation process, see

  2. To start and stop the server, use the 'electrum-server' script
