Commands  [DigitalBits Core]

digitalbits-core can be controlled via the following commands.

Command line options

  • –? or –help: Print the available command line options and then exit…
  • –c Send an HTTP command to an already running local instance of digitalbits-core and then exit. For example:

$ digitalbits-core -c info

  • –conf FILE: Specify a config file to use. You can use ‘-’ and provide the config file via STDIN. default ‘digitalbits-core.cfg’
  • –convertid ID: Will output the passed ID in all known forms and then exit. Useful for determining the public key that corresponds to a given private key. For example:


  • –dumpxdr FILE: Dumps the given XDR file and then exits.
  • –loadxdr FILE: Load an XDR bucket file, for testing.
  • –forcescp: This command is used to start a network from scratch or when a network has lost quorum because of failed nodes or otherwise. It sets a flag in the database. The next time digitalbits-core is run, digitalbits-core will start emitting SCP messages based on its last known ledger. Without this flag digitalbits-core waits to hear a ledger close from the network before starting SCP.
    forcescp doesn’t change the requirements for quorum so although this node will emit SCP messages SCP won’t complete until there are also a quorum of other nodes also emitting SCP messages on this same ledger.
  • –fuzz FILE: Run a single fuzz input and exit.
  • –genfuzz FILE: Generate a random fuzzer input file.
  • –genseed: Generate and print a random public/private key and then exit.
  • –inferquorum: Print a potential quorum set inferred from history.
  • –checkquorum: Check quorum intersection from history to ensure there is closure over all the validators in the network.
  • –graphquorum: Print a quorum set graph from history.
  • –offlineinfo: Returns an output similar to --c info for an offline instance
  • –ll LEVEL: Set the log level. It is redundant with --c ll but we need this form if you want to change the log level during test runs.
  • –metric METRIC: Report metric METRIC on exit. Used for gathering a metric cumulatively during a test run.
  • –newdb: Clears the local database and resets it to the genesis ledger. If you connect to the network after that it will catch up from scratch.
  • –newhist ARCH: Initialize the named history archive ARCH. ARCH should be one of the history archives you have specified in the digitalbits-core.cfg. This will write a .well-known/digitalbits-history.json file in the archive root.
  • –printtxn FILE: Pretty-print a binary file containing a TransactionEnvelope. If FILE is “-”, the transaction is read from standard input.
  • –signtxn FILE: Add a digital signature to a transaction envelope stored in binary format in FILE, and send the result to standard output (which should be redirected to a file or piped through a tool such as base64). The private signing key is read from standard input, unless FILE is “-” in which case the transaction envelope is read from standard input and the signing key is read from /dev/tty. In either event, if the signing key appears to be coming from a terminal, digitalbits-core disables echo. Note that if you do not have a STELLAR_NETWORK_ID environment variable, then before this argument you must specify the --netid option.
  • –base64: When preceding --printtxn or --signtxn, alters the behavior of the option to work on base64-encoded XDR rather than raw XDR.
  • –sec2pub: Reads a secret key on standard input and outputs the corresponding public key. Both keys are in DigitalBits’s standard base-32 ASCII format.
  • –netid STRING: The --signtxn option requires a particular network to sign for. For example, the production DigitalBits network is "Live DigitalBits Network ; March 2018" while the test network is “Test DigitalBits Network ; December 2017”.
  • –test: Run all the unit tests. For further info on possible options for test. For example this will run just the “Herder” tests and stop after the first failure: digitalbits-core --test -a [Herder]
  • –version: Print version info and then exit.

HTTP Commands

By default digitalbits-core listens for connections from localhost on port 11626. You can send commands to digitalbits-core via a web browser, curl, or using the --c command line option (see above). Most commands return their results in JSON format.

  • help Prints a list of currently supported commands.

  • catchup /catchup?ledger=NNN[&mode=MODE]
    Triggers the instance to catch up to ledger NNN from history; Mode is either ‘minimal’ (the default, if omitted) or ‘complete’.

  • checkdb Triggers the instance to perform a background check of the database’s state.

  • checkpoint Triggers the instance to write an immediate history checkpoint. And uploads it to the archive.

  • connect /connect?peer=NAME&port=NNN
    Triggers the instance to connect to peer NAME at port NNN.

  • dropcursor
    deletes the tracking cursor with identified by id. See setcursor for more information.

  • info Returns information about the server in JSON format (sync state, connected peers, etc).

  • ll
    Adjust the log level for partition P (or all if no partition is specified). Level is one of FATAL, ERROR, WARNING, INFO, DEBUG, VERBOSE, TRACE

  • maintenance /maintenance?[queue=true]
    Performs maintenance tasks on the instance.

    • queue performs deletion of queue data. See setcursor for more information.
  • metrics Returns a snapshot of the metrics registry (for monitoring and debugging purpose).

  • peers Returns the list of known peers in JSON format.

  • quorum /quorum?[node=NODE_ID][&compact=true]
    returns information about the quorum for node NODE_ID (this node by default). NODE_ID is either a full key (GABCD...), an alias ($name) or an abbreviated ID (@GABCD). If compact is set, only returns a summary version.

  • setcursor /setcursor?id=ID&cursor=N
    sets or creates a cursor identified by ID with value N. ID is an uppercase AlphaNum, N is an uint32 that represents the last ledger sequence number that the instance ID processed. Cursors are used by dependent services to tell digitalbits-core which data can be safely deleted by the instance. The data is historical data stored in the SQL tables such as txhistory or ledgerheaders. When all consumers processed the data for ledger sequence N the data can be safely removed by the instance. The actual deletion is performed by invoking the maintenance endpoint or on startup. See also dropcursor.

  • getcursor /getcursor?[id=ID]
    gets the cursor identified by ID. If ID is not defined then all cursors will be returned.

  • scp `/scp?[limit=n] Returns a JSON object with the internal state of the SCP engine for the last n (default 2) ledgers.

  • tx /tx?blob=Base64
    submit a transaction to the network. blob is a base64 encoded XDR serialized ‘TransactionEnvelope’, and it returns a JSON object with the following properties status:

    • “PENDING” - transaction is being considered by consensus
    • “DUPLICATE” - transaction is already PENDING
    • “ERROR” - transaction rejected by transaction engine error: set when status is “ERROR”. Base64 encoded, XDR serialized ‘TransactionResult’
  • upgrades

    • /upgrades?mode=get
      retrieves the currently configured upgrade settings
    • /upgrades?mode=clear
      clears any upgrade settings
    • /upgrades?mode=set&upgradetime=DATETIME&[basefee=NUM]&[basereserve=NUM]&[maxtxsize=NUM]&[protocolversion=NUM]
      upgradetime is a required date (UTC) in the form 1970-01-01T00:00:00Z.
      • fee (uint32) This is what you would prefer the base fee to be. It is in stroops
      • basereserve (uint32) This is what you would prefer the base reserve to be. It is in stroops.
      • maxtxsize (uint32) This defines the maximum number of transactions to include in a ledger. When too many transactions are pending, surge pricing is applied. The instance picks the top maxtxsize transactions locally to be considered in the next ledger. Where transactions are ordered by transaction fee(lower fee transactions are held for later).
      • protocolversion (uint32) defines the protocol version to upgrade to. When specified it must match the protocol version supported by the node

The following HTTP commands are exposed on test instances

  • generateload /generateload[?accounts=N&txs=M&txrate=(R|auto)]
    Artificially generate load for testing; must be used with ARTIFICIALLY_GENERATE_LOAD_FOR_TESTING set to true.

  • manualclose If MANUAL_CLOSE is set to true in the .cfg file. This will cause the current ledger to close.

  • testacc /testacc?name=N
    Returns basic information about the account identified by name. Note that N is a string used as seed, but “root” can be used as well to specify the root account used for the test instance.

  • testtx /testtx?from=F&to=T&amount=N&[create=true]
    Injects a payment transaction (or a create transaction if “create” is specified) from the account F to the account T, sending N XDB to the account. Note that F and T are seed strings but can also be specified as “root” as a shorthand for the root account for the test instance.
