Automatically listen on Tor +-------------------------------- + +Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket +API, to create and destroy 'ephemeral' hidden services programmatically. +Bitcoin Core has been updated to make use of this. + +This means that if Tor is running (and proper authorization is available), +Bitcoin Core automatically creates a hidden service to listen on, without +manual configuration. This will positively affect the number of available +.onion nodes. + +This new feature is enabled by default if Bitcoin Core is listening, and +a connection to Tor can be made. It can be configured with the `-listenonion`, +`-torcontrol` and `-torpassword` settings. To show verbose debugging +information, pass `-debug=tor`. |
