📄 CLI Reference

The cli subcommand provides a human-friendly command-line interface to the node JSON-RPC API.

Usage

See all the available options by running the help command using docker, binary or cargo.

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node --help

{% endtab %}

{% tab title="Binary" %}

witnet node --help

{% endtab %}

{% tab title="Cargo" %}

cargo run -- node --help

{% endtab %} {% endtabs %}

To get more information about any specific command, simply add --help at the end. For instance, this will show the available options for the blockchain command:

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node blockchain --help

{% endtab %}

{% tab title="Binary" %}

witnet node blockchain --help

{% endtab %}

{% tab title="Cargo" %}

cargo run -- node blockchain --help

{% endtab %} {% endtabs %}

The JSON-RPC server address is obtained from the configuration-file.md. The path of this file can be set using the -c or --config flag. This flag must appear before node.

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node -c witnet.toml node blockchain

{% endtab %}

{% tab title="Binary" %}

witnet -c witnet.toml node blockchain

{% endtab %}

{% tab title="Cargo" %}

cargo run -- -c witnet.toml node blockchain

{% endtab %} {% endtabs %}

You can use the -n flag to easily overwrite the node address. This flag must appear after the command name.

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node -c witnet.toml node blockchain -n "127.0.0.1:1234"

{% endtab %}

{% tab title="Binary" %}

witnet -c witnet.toml node blockchain -n "127.0.0.1:1234"

{% endtab %}

{% tab title="Cargo" %}

cargo run -- -c witnet.toml node blockchain -n "127.0.0.1:1234"

{% endtab %} {% endtabs %}

If there is any error, the process will return a non-zero exit code.

{% tabs %} {% tab title="Docker" %}

    docker exec witnet_node witnet node node blockchain
    Error: Connection refused (os error 111)

{% endtab %}

{% tab title="Binary" %}

    witnet node blockchain
    Error: Connection refused (os error 111)

{% endtab %}

{% tab title="Cargo" %}

    cargo run -- node blockchain
    Error: Connection refused (os error 111)

{% endtab %} {% endtabs %}

The executable implements the usual logging API, which can be enabled using RUST_LOG=witnet=debug:

{% tabs %} {% tab title="Docker" %}

Among other information, this shows counters for proposed and accepted blocks and participations in resolving data requests ("commitments"):

Block mining stats

• Proposed blocks
• Blocks included in the block chain

Data Request mining stats:

• Times with eligibility to mine a data request
• Proposed commits
• Accepted commits
• Slashed commits

Example output:

Block mining stats:
- Proposed blocks: 81
- Blocks included in the block chain: 1
Data Request mining stats:
- Times with eligibility to mine a data request: 2
- Proposed commits: 0
- Accepted commits: 0
- Slashed commits: 0

!!! tip Note that it is perfectly normal for a node to show 0 "blocks included" or "accepted commits" for the first days of it being up. Please be patient, new identities in the system are subject to a slow start for critical security reasons.

output

Display a transaction output, as referred by it's "output pointer", that is, <transaction_id>:<output_index>.

{% endtab %} {% endtabs %}

peers

List inbound and outbound connections currently established by the node. Outbound connections are those initiated on our side, and inbound connections are those that were initiated by peer nodes. A node that does not announce a public address (IP and port) will normally have no inbound connections, as there is no way for other nodes to discover a valid network route to it.

priority

Display priority and time-to-block estimations for different priority tiers according to the current state of the network. The priority is measured in nanowits per weight unit, so you can calculate a fee by multiplying the priority by the weight of the transaction.

raw

The raw command allows sending raw JSON-RPC requests from the command line. It can be used in an interactive way (don't forget the -i flag when using Docker): each line of user input will be sent to the JSON-RPC server without any modifications:

{% tabs %} {% tab title="Docker" %}

$ docker exec -i witnet_node witnet node raw

{% endtab %}

{% tab title="Binary" %}

$ witnet -c witnet.toml node raw

{% endtab %}

{% tab title="Cargo" %}

$ cargo run -- -c witnet.toml node raw

{% endtab %} {% endtabs %}

Each block represents a method call: the first line is a request, the second line is a response.

hi
{"jsonrpc": "2.0","error": {"code":-32700,"message": "Parse error"},"id":null}

{"jsonrpc": "2.0","method": "blockChain", "id": 1}
{"jsonrpc": "2.0","result": [[242037,"3f8c9ed0fa721e39de9483f61f290f76a541757a828e54a8d951101b1940c59a"]],"id":1}

{"jsonrpc": "2.0","method": "someInvalidMethod", "id": 2}
{"jsonrpc": "2.0","error": {"code":-32601,"message": "Method not found"},"id":2}

bye
{"jsonrpc": "2.0","error": {"code":-32700,"message": "Parse error"},"id":null}

Alternatively, the input can be read from a file using pipes, as is usual in Unix-like environments. For instance, the bitcoin_price.json data request example from the witnet-rust reposity can be easily deployed into the network using the raw command like this:

{% tabs %} {% tab title="Docker" %}

cat examples/bitcoin_price.json | docker exec -i witnet_node witnet node raw
    {"jsonrpc": "2.0","result": "06e19d996a6776d6cd1ca215f6acd0975d71e64a9dacc06fcfdd7b2538cdbf6d","id": "1"}

{% endtab %}

{% tab title="Binary" %}

cat examples/bitcoin_price.json | witnet node raw
    {"jsonrpc": "2.0","result": "06e19d996a6776d6cd1ca215f6acd0975d71e64a9dacc06fcfdd7b2538cdbf6d","id": "1"}

{% endtab %}

{% tab title="Cargo" %}

cat examples/bitcoin_price.json | cargo run -- node raw
    {"jsonrpc": "2.0","result": "06e19d996a6776d6cd1ca215f6acd0975d71e64a9dacc06fcfdd7b2538cdbf6d","id": "1"}

{% endtab %} {% endtabs %}

reputation

Displays the reputation score associated with a given Witnet address and its elegibility to mine a block.

• --address=address: address for which to get reputation score. If omitted, defaults to the node's own address.

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node reputation
    docker exec witnet_node witnet node reputation --address=twit1p2my760gmg4gwsnhunwnx3epvj9c4whnsnn8j4

{% endtab %}

{% tab title="Binary" %}

witnet node reputation
    witnet node reputation --address=twit1p2my760gmg4gwsnhunwnx3epvj9c4whnsnn8j4

{% endtab %}

{% tab title="Cargo" %}

cargo run -- node reputation
    cargo run -- node reputation --address=twit1p2my760gmg4gwsnhunwnx3epvj9c4whnsnn8j4

{% endtab %} {% endtabs %}

Example output:

[A] twit1p2my760gmg4gwsnhunwnx3epvj9c4whnsnn8j4 -> Reputation: 1, Eligibility: 28.571429%

The parameter [A] notifies that the node is active.

Adding the flag --all lists all the nodes active and their elegibility. It also lists the nodes with reputation grater than 0 but not active, if any.

!!! tip Note that it is perfectly normal for a node to show 0 reputation for the first days of it being up. Please be patient, new identities in the system are subject to a slow start for critical security reasons.

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node reputation --all

{% endtab %}

{% tab title="Binary" %}

witnet node reputation --all

{% endtab %}

{% tab title="Cargo" %}

cargo run -- node reputation --all

{% endtab %} {% endtabs %}

Example output:

Total Reputation: {
    [A] twit1hgert0dwtfmfcnv34epvjyhwamny20vkx09zjc -> Reputation: 2, Eligibility: 42.857143%
    [A] twit1p2my760gmg4gwsnhunwnx3epvj9c4whnsnn8j4 -> Reputation: 1, Eligibility: 28.571429%
    [A] twit18gqex3jg4pazz5am2588fc89qyvg350gs603j2 -> Reputation: 1, Eligibility: 28.571429%

}

send

Create and broadcast a value transfer transaction. That is, send some amount of wit tokens from the node's own balance into a different Witnet address.

• --address=address: recipient address.
• --value=amount: amount in nanoWits.
• --fee=fee: miner fee in nanoWits.
• --time-lock=timestamp: optional time lock for the created output: the receiver will not be able to spend the output until the timestamp is reached. 0 means no time-lock.

On success, returns the transaction hash:

{% tabs %} {% tab title="Docker" %}

utxos

Get the unspent transaction outputs of the node. This shows how many UTXOs are available for your node to spend or collateralize.

{% tabs %} {% tab title="Docker" %}

docker exec witnet_node witnet node utxos

{% endtab %}

{% tab title="Binary" %}

witnet node utxos

{% endtab %}

{% tab title="Cargo" %}

cargo run -- node utxos

{% endtab %} {% endtabs %}

The output includes information about:

• Total number of utxos
• Total number of utxos bigger than collateral minimum
• Total number of utxos older than collateral coinage

The flag --long can be added to the command to get a detailed list of the UTXOs and whether each of them is spendable or collateralizable at this time.
