remme¶

The remme command is the usual way to interact with validators or validator networks.

This command has a multi-level structure. It starts with the base call to remme. Next is a top-level subcommand such as block or state. Each top-level subcommand has additional subcommands that specify the operation to perform, such as list or create. The subcommands have options and arguments that control their behavior. For example:

$ remme state list --format csv

usage: remme [-h] [-v] [-V]
                {batch,block,identity,keygen,peer,status,settings,state,transaction}
                ...

Provides subcommands to configure, manage, and use Sawtooth components.

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose         enable more verbose output
  -V, --version         display version information

subcommands:
  {batch,block,identity,keygen,peer,status,settings,state,transaction}
    batch               Displays information about batches and submit new
                        batches
    block               Displays information on blocks in the current
                        blockchain
    identity            Works with optional roles, policies, and permissions
    keygen              Creates user signing keys
    peer                Displays information about validator peers
    status              Displays information about validator status

remme batch list¶

The remme batch list subcommand queries the specified remme REST API (default: http://localhost:8008) for a list of Batches in the current blockchain. It returns the id of each Batch, the public key of each signer, and the number of transactions in each Batch.

By default, this information is displayed as a white-space delimited table intended for display, but other plain-text formats (CSV, JSON, and YAML) are available and can be piped into a file for further processing.

usage: remme batch list [-h] [--url URL] [-u USERNAME[:PASSWORD]]
                           [-F {csv,json,yaml,default}]

remme batch submit¶

The remme batch submit subcommand sends one or more Batches to the remme REST API to be submitted to the validator. The input is a binary file with a binary-encoded BatchList protobuf, which can contain one or more batches with any number of transactions. The --wait option indicates that results should not be returned until processing is complete, with an optional timeout specified in seconds.

This subcommand requires the URL of the REST API (default: http://localhost:8008), and can specify a username:password combination when the REST API is behind a Basic Auth proxy.

remme identity¶

remme supports an identity system that provides an extensible role- and policy-based system for defining permissions in a way which can be used by other pieces of the architecture. This includes the existing permissioning components for transactor key and validator key; in the future, this feature may also be used by transaction family implementations. The remme identity subcommands can be used to view the current roles and policy set in state, create new roles, and new policies.

Note that only the public keys stored in the setting remme.identity.allowed_keys are allowed to submit identity transactions. Use the sawset commands to change this setting.

    list         Lists the current policies

remme identity policy create¶

The remme identity policy create subcommand creates a new policy that can then be set to a role. The policy should contain at least one “rule” (PERMIT_KEY or DENY_KEY). Note that all policies have an assumed last rule to deny all. This subcommand can also be used to change the policy that is already set to a role without having to also reset the role.

usage: remme identity policy create [-h] [-k KEY] [-o OUTPUT | --url URL]
                                       [--wait WAIT]

subcommands:
  {show}

remme status show¶

The remme status subcommand displays information related to a validator’s current status, including its public network endpoint and its peers.

This subcommand requires the URL of the REST API (default: http://localhost:8008), and can specify a username:password combination when the REST API is behind a Basic Auth proxy.

usage: remme status show [-h] [--url URL] [-u USERNAME[:PASSWORD]]
                            [-F {csv,json,yaml,default}]

Displays information about the status of a validator.

optional arguments:
  -h, --help            show this help message and exit
  --url URL             identify the URL of the validator's REST API (default:
                        http://localhost:8008)
  -u USERNAME[:PASSWORD], --user USERNAME[:PASSWORD]
                        specify the user to authorize request
  -F {csv,json,yaml,default}, --format {csv,json,yaml,default}
                        choose the output format

remme transaction¶

The remme transaction subcommands display information about the transactions in the current blockchain.

usage: remme transaction [-h] {list,show} ...

Provides subcommands to display information about the transactions in the
current blockchain.

optional arguments:
  -h, --help   show this help message and exit

subcommands:
  {list,show}

remme transaction list¶

The remme transaction list subcommand queries the remme REST API (default: http://localhost:8008) for a list of transactions in the current blockchain. It returns the id of each transaction, its family and version, the size of its payload, and the data in the payload itself.

By default, this information is displayed as a white-space delimited table intended for display, but other plain-text formats (CSV, JSON, and YAML) are available and can be piped into a file for further processing.

usage: remme transaction list [-h] [--url URL] [-u USERNAME[:PASSWORD]]
                                 [-F {csv,json,yaml,default}]

Lists all transactions in the current blockchain.

optional arguments:
  -h, --help            show this help message and exit
  --url URL             identify the URL of the validator's REST API (default:
                        http://localhost:8008)
  -u USERNAME[:PASSWORD], --user USERNAME[:PASSWORD]
                        specify the user to authorize request
  -F {csv,json,yaml,default}, --format {csv,json,yaml,default}
                        choose the output format

remme transaction show¶

The remme transaction show subcommand queries the remme REST API for a specific transaction in the current blockchain. It returns complete information for this transaction in either YAML (default) or JSON format. Use the --key option to narrow the returned information to just the value of a single key, either from the transaction or its header.

This subcommand requires the URL of the REST API (default: http://localhost:8008), and can specify a username:password combination when the REST API is behind a Basic Auth proxy.

usage: remme transaction show [-h] [--url URL] [-u USERNAME[:PASSWORD]]
                                 [-k KEY] [-F {yaml,json}]
                                 transaction_id

Displays information for the specified transaction.

positional arguments:
  transaction_id        id (header_signature) of the transaction

optional arguments:
  -h, --help            show this help message and exit
  --url URL             identify the URL of the validator's REST API (default:
                        http://localhost:8008)
  -u USERNAME[:PASSWORD], --user USERNAME[:PASSWORD]
                        specify the user to authorize request
  -k KEY, --key KEY     show a single property from the block or header
  -F {yaml,json}, --format {yaml,json}
                        choose the output format (default: yaml)
