      User value:
    • Prune Blocks prune
      Reduce storage requirements by enabling pruning (deleting) of old blocks. This allows the pruneblockchain RPC to be called to delete specific blocks and enables automatic pruning of old blocks if a target size in MiB is provided. This mode is incompatible with txindex and coinstatsindex. WARNING: Reverting this setting requires re-downloading the entire blockchain. (0 = disable pruning blocks, 1 = allow manual pruning via RPC, greater or equal 550 = automatically prune blocks to stay under target size in MiB)
      Default: 0
      User value:

      User value:
    • Reindex reindex
      If enabled, wipe chain state and block index, and rebuild them from blk*.dat files on disk. Also wipe and rebuild other optional indexes that are active. If an assumeutxo snapshot was loaded, its chainstate will be wiped as well. The snapshot can then be reloaded via RPC. Setting this to auto automatically reindexes the block database if it is corrupted
      Options: 0, 1, auto
      Default: 0
      User value:
    • Reindex Chainstate reindex-chainstate
      If enabled, wipe chain state, and rebuild it from blk*.dat files on disk. If an assumeutxo snapshot was loaded, its chainstate will be wiped as well. The snapshot can then be reloaded via RPC
      Default: 0
      User value:
    • Settings File settings
      Specify path to dynamic settings data file. Can be disabled with nosettings. File is written at runtime and not meant to be edited by users (use bitcoin.conf instead for custom settings). Relative paths will be prefixed by datadir location
      Default: settings.json
      User value:
    • Shutdown Notification shutdownnotify
      Execute command immediately before beginning shutdown. The need for shutdown may be urgent, so be careful not to delay it long (if the command doesn't require interaction with the server, consider having it fork into the background)
      User value:
    • Software Expiry softwareexpiry
      Knots exclusive
      Stop working after this POSIX timestamp. (0 = disable)
      Default: 1857151480
      User value:
    • Startup Notification startupnotify
      Execute command on startup
      User value:
