Configuration for the Theta Blockchain Node

The theta blockchain node can be launched with parameter --config=path/to/config/folder as shown in the command below.

theta start --config=../privatenet/node

If the --config parameter is not specified, the theta node uses ~/.theta as the default config folder. The theta node also uses the config directory to store other important data. For example, it stores its encrypted key under the key folder, and the blockchain data under the db folder.

The configuration for the theta node is defined by file config.yaml under path/to/config/folder. Below are the options

  statePruningEnabled: true # true by default, when set to true the node will perform state pruning which can effectively reduce the disk space consumption
  statePruningInterval: 16 # the purning interval (in terms of blocks) which control the frequency the pruning procedure is activated
  statePruningRetainedBlocks: 2048 # the number of blocks prior to the latest finalized block whose corresponding state tree need to be retained
  address: # the binding address of the RPC service, by default
  port: 50001 # the p2p port that the Theta node listens on, 50001 by default
  seeds:,, # the IP addresses of the seed nodes
  enabled: true # false by default, when set to true the RPC API is enabled
  port: 16888 # the PRC API port, 16888 by default
  maxConnections: 100 # max number of simultaneous RPC connections, 200 by default
  levels: "*:info" # level of logs to be printed, "*:debug" by default
