Control de monedas#

El control de monedas permite a los usuarios de la billetera Dash Core especificar qué direcciones y salidas de transacciones no utilizadas (UTXOs) deben usarse como entradas en las transacciones. Esto te permite mantener un saldo específico en ciertas direcciones en tu billetera, mientras que gastas otros libremente. En la billetera Dash Core, haz clic en Configuración > Opciones > Billetera > Habilitar funciones de control de monedas. Ahora, cuando vayas a la pestaña Enviar en tu billetera, aparecerá un nuevo botón con la etiqueta Entradas … Haz click en este botón para seleccionar qué UTXOs se pueden usar como entrada para cualquier transacción que crees. La siguiente ventana aparecerá:

Haz click derecho en las transacción(es) que no deseas gastar, luego selecciona Bloquear sin gastar. Aparecerá un pequeño candado junto a la transacción. Puedes hacer click en el botón Conmutar estado de bloqueo para invertir el estado bloqueado/desbloqueado de todos los UTXOs. Cuando estés listo para continuar, haz click en Aceptar. Ahora puedes crear transacciones de forma segura con los fondos restantes sin afectar los UTXOs bloqueados.

Bloquear UTXOs en la billetera Dash Core#

BIlleteras HD#

Enable HD Wallet Creation#

Dash Core includes an implementation of BIP39/BIP44 compatible hierarchical deterministic (HD) key generation. We will use the Windows GUI wallet in this example, but the commands are similar if using dash-qt or dashd on other operating systems. Enter the following command to configure Dash Core to generate HD wallets by default:

dash-qt.exe -usehd

To make this configuration persist between restarts, add usehd=1 to the dash.conf file.

View HD wallet information#

Open the console from Window > Console or issue the following RPC command from dash-cli to view the mnemonic seed:

dumphdinfo

Dash Core will display the HD seed in both hexadecimal and BIP39 mnemonic formats. It will also display the mnemonic passphrase if one was used when creating the wallet.

Upgrade to HD#

Advertencia

A new backup must be created after upgrading to an HD wallet.

Dash Core includes the ability upgrade a non-hierarchical deterministic (HD) wallet to an HD wallet via the upgradetohd command. The command can be run by either opening the console from Window > Console or issuing the following RPC command from dash-cli:

upgradetohd "" "" <walletpassphrase>

If your wallet is already encrypted you must enter the passphrase as the third parameter to the command. If your wallet is not already encrypted, specifying a wallet passphrase will trigger wallet encryption.

To see full details for the command, run the following from either the console or dash-cli:

help upgradetohd

Restore HD wallet#

To restore an existing HD wallet, or define your own separately generated mnemonic and/or passphrase, create a new blank wallet with following command:

createwallet "enter wallet name" false true "optional wallet password"

Add the HD wallet details to the newly created wallet by running:

upgradetohd "enter mnemonic" "optional mnemonic passphrase" "optional wallet passphrase"

La billetera HD sera restaurada y tu balance aparecerá una vez que la sincronización esta completa.

Note that the wallet passphrase is different to the mnemonic passphrase, which is often also referred to as the «25th word» or «extension word». The wallet passphrase encrypts the wallet file itself, while the mnemonic passphrase is used to specify different derivation branches from the same mnemonic seed.

Multifirma#

Esta sección presenta un ejemplo trabajado para demostrar la funcionalidad multifirma en Dash Core. Si bien las transacciones ya no son visibles en la cadena de bloques de la red de prueba actual y algunos formatos de direcciones o respuestas de RPC pueden diferir ligeramente de la versión que se muestra aquí, el principio y los comandos son los mismos. El ejemplo muestra cómo configurar una dirección multifirma de 2-de-3 y crear una transacción. Las partes de ejemplo involucradas son un comprador, un vendedor y un árbitro. Este ejemplo se basa en:

Paso 1: Crear tres direcciones#

Esto resulta en tres pares de llaves (pública/privada):

seller:    02a862b412ff9e3afd01a2873a02622897f6df92e3fc85597788b898309fec882e / cVQVgBr8sW4FTPYz16BSCo1PcAfDhpJArgMPdLxKZQWcVFwMXRXx

Paso 2: Crear una dirección multifirma#

El comando createmultisig toma como variables el número n de firmas de m claves (suministradas como arreglo json) requeridas. En este ejemplo, se requieren 2 de 3 llaves para firmar la transacción.

Nota: Cualquier persona puede crear la dirección, siempre que se conozcan las llaves públicas y su secuencia (la dirección resultante y redeemScript son idénticos, ver abajo).

Vendedor:

}

Paso 3: el comprador financia la dirección multifirma#

Esto funciona igual que una transacción normal.

Comprador:

buyer@testnet03:~$ ./dash-cli sendtoaddress 2MuEQCZh7VB8pNrT4bj1CFZQh2oK7XZYLQf 777.77
a8b3bf5bcace91a8dbbddbf9b7eb027efb9bd001792f043ecf7b558aaa3cb951

El vendedor/árbitro puede rastrear la transacción por su txid en el explorador de bloques. O desde la consola de la siguiente manera.

Comprador:

seller@testnet03:~$ ./dash-cli getrawtransaction a8b3bf5bcace91a8dbbddbf9b7eb027efb9bd001792f043ecf7b558aaa3cb951 1

Paso 4: Gastar la multifirma#

Ahora suponemos que el trato está completo, el comprador obtuvo los productos y todos están contentos. Ahora el vendedor quiere obtener sus Dash. Como se utilizó una multifirma de 2-de-3, la transacción debe estar firmada por 2 partes (vendedor + comprador o árbitro). El vendedor crea una transacción (reutilizaremos su dirección pública de arriba).

Ten en cuenta que el hexágono de salida se hace más largo, pero el indicador completo es «falso» ya que la transacción necesita otra firma. Entonces, ahora el comprador o el árbitro pueden completar la firma de la transacción, utilizando el resultado de arriba y sus llaves privada. Supongamos que el comprador está completando la firma.

Daemon#

Dash can be run as a background process (or daemon) on Linux systems. This is particularly useful if you are running Dash as a server instead of as a GUI node. This guide assumes you have installed Dash Core for Linux as described in the Guía de instalación de Linux.

  1. Create a user and group to run the daemon:

    sudo useradd -m dash -s /bin/bash

  2. Create a data directory for Dash in the new user’s home directory:

    sudo -u dash mkdir -p /home/dash/.dashcore

  3. Create a configuration file in the new Dash data directory:

    sudo -u dash nano /home/dash/.dashcore/dash.conf

  4. Paste the following basic configuration to your dash.conf file, replacing the password with a long and random password:

    listen=1
server=1
daemon=1

  5. Register the dashd daemon as a system service by creating the following file:

    sudo nano /etc/systemd/system/dashd.service

  6. Paste the following daemon configuration into the file:

    [Unit]
Description=Dash Core Daemon
After=syslog.target network-online.target

[Service]
Type=forking
User=dash
Group=dash
OOMScoreAdjust=-1000
ExecStart=/usr/local/bin/dashd -pid=/home/dash/.dashcore/dashd.pid
TimeoutStartSec=10m
ExecStop=/usr/local/bin/dash-cli stop
TimeoutStopSec=120
Restart=on-failure
RestartSec=120
StartLimitInterval=300
StartLimitBurst=3

[Install]
WantedBy=multi-user.target

  7. Register and start the daemon with systemd:

    sudo systemctl daemon-reload
sudo systemctl enable dashd
sudo systemctl start dashd

Dash is now installed as a system daemon. View the status as follows:

systemctl status dashd

View logs as follows:

sudo journalctl -u dashd

Tor#

Tor is free and open-source software for enabling anonymous communication. The name derived from the acronym for the original software project name «The Onion Router». Tor directs Internet traffic through a free, worldwide, volunteer overlay network consisting of more than seven thousand relays to conceal a user’s location and usage from anyone conducting network surveillance or traffic analysis.

Dash Core GUI#

Dash Core traffic can be directed to pass through Tor by specifying a running Tor service as a proxy. First install Tor by visiting https://www.torproject.org/download/ and downloading the appropriate Tor Browser bundle for your system. Set up the Tor browser by following the documentation on Installation and Running Tor Browser for the First Time.

Once Tor Browser is running, you have two options to configure Dash Core to use Tor for network traffic.

  1. Using the GUI: Start Dash Core and go to Settings > Options > Network and enable the Connect through SOCKS5 proxy setting. Specify 127.0.0.1 for the Proxy IP and 9150 for the Port. Click OK and restart Dash Core.

  2. Using dash.conf: Ensure Dash Core is not running and edit your dash.conf settings file. Add the line proxy=127.0.0.1:9150, save the file and start Dash Core.

You are now connected through the Tor network. You will need to remember to start the Tor Browser each time before you start Dash Core or you will not be able to sync.

Tor onion service#

Tor onion services allows other users to connect to your Dash node using an onion address, providing further anonymity by concealing your IP address. Follow these steps to set up an onion service under Ubuntu Linux:

  1. Install tor:

    sudo apt install tor

  2. Add the following line to the torrc file:

    sudo bash -c "echo -e 'ControlPort 9051\nCookieAuthentication 1\nCookieAuthFileGroupReadable 1' >> /etc/tor/torrc"

  3. Restart Tor:

    sudo systemctl restart tor

  4. Determine the group Tor is running under (usually the last entry in your groups file):

    tail /etc/group

    The group is usually debian-tor under Debian-based Linux distributions.

  5. Add the user running Dash to the Tor group:

    sudo usermod -aG debian-tor dash

  6. Add the following two lines to dash.conf:

    proxy=127.0.0.1:9050
torcontrol=127.0.0.1:9051

  7. Restart Dash and monitor debug.log for onion informatoin:

    grep -i onion ~/.dashcore/debug.log

    You should see a line similar to the following:

    2020-06-29 03:43:57 tor: Got service ID knup3fvr6fyvypu7, advertising service knup3fvr6fyvypu7.onion:19999

Your onion service is now available at the shown address.

Múltiples billeteras#

Since version 18.0.0, Dash Core has included the ability work with multiple wallets from the File menu in addition to the previously available options.

Advertencia

Wallet-related RPCs require using the -rpcwallet option when more than one wallet file is loaded. This is to ensure the RPC command is executed using the correct wallet. See the Core developer documentation for additional information.

Open a wallet#

To open a wallet, click File -> Open Wallet and then click the name of wallet file.

../../../../_images/wallet-open.png

Open wallet#

Select the active wallet#

When multiple wallets are open, a wallet selection dropbox is shown to the left of the Dash logo on the tab bar. Click the dropdown box and select a wallet to set it as the active wallet.

../../../../_images/wallet-select-dropdown.png

Wallet selection dropdown box#

Close a wallet#

To close a wallet, set it as the active wallet using the wallet selection dropdown box. Next, click File -> Close Wallet and then click Yes on the Close wallet confirmation screen.

../../../../_images/wallet-close-confirmation.png

Close wallet confirmation#

Nota

If the only open wallet is closed, wallet-related items on the tab bar will be disabled.

Alternative methods#

It is also possible to select between different Dash wallets when starting Dash Core by specifying the wallet argument, or even run multiple instances of Dash Core simultaneously by specifying separate data directories using the datadir argument.

Para empezar, instala la billetera Dash Core para tu sistema de acuerdo a la instrucciones de instalación. Cuando llegues al paso Ejecutando Dash Core por primera vez, puedes decidir si desea mantener archivos `` wallet.dat`` separados en la ubicación predeterminada (más sencillo si no necesita ejecutar las carteras simultáneamente), o especificar directorios de datos completamente separados como, por ejemplo, `` C: Dash1`` (más simple si desea ejecutar las carteras simultáneamente).

Archivos wallet.dat separados#

Para este escenario, crearemos dos atajos en el escritorio, cada uno usando un archivo de billetera diferente. Navega al archivo binario usado para iniciar Dash Core (tipicamente localizado en C:\Program Files\DashCore\dash-qt.exe o similar) y crea dos atajos en el escritorio. Entonces abre la ventana Propiedades para cada uno de estos atajos.

../../../../_images/shortcuts.png

Creando atajos de escritorio usando Windows 10#

Modificar la propiedad Objetivo de cada acceso directo para puntar a diferentes archivos de billeteras especificando la el argumento wallet cuando inicia la billetera. Si no especificas un argumento wallet, wallet.dat se usara por defecto. El archivo billetera especificado sera creado sino existe. Los siguientes ejemplos muestran dos billeteras nombradas workwallet.dat y homewallet.dat:

  • Billetera Objetivo 1: "C:\Program Files\DashCore\dash-qt.exe" -wallet=workwallet.dat

  • Billetera Objetivo 2: "C:\Program Files\DashCore\dash-qt.exe" -wallet=homewallet.dat

../../../../_images/walletfiles.png

Especificando archivos de billeteras separadas#

Puedes usar ahora los dos iconos para abrir rápida y fácilmente diferentes billeteras desde tu escritorio. Ten en cuenta que no puedes abrir ambas billeteras simultáneamente. Para hacer esto, necesitas dos directorios de datos separados, como se describe abajo.

Directorios de datos separados#

Inicia la Dash Core y deja que sincronice con la red, luego cierra la Dash Core de nuevo. Ahora puedes crear dos directorios por ejemplo C:\Dash1 y C:\Dash2 y copia los directorios blocks y chainstate dentro del directorio de datos sincronizado a los nuevos directorios. Cada uno estos servirá como un directorio de datos separado, permitiendo que ejecutes dos instancias de la Dash Core simultáneamente. Crea dos (o mas) atajos en tu escritorio como se describe abajo, entonces especifica el argumento datadir como se muestra abajo:

  • Datadir Objetivo 1: "C:\Program Files\DashCore\dash-qt.exe" -datadir=C:\Dash1 -listen=0

  • Datadir Objetivos 2: "C:\Program Files\DashCore\dash-qt.exe" -datadir=C:\Dash2 -listen=0

../../../../_images/datadirs.png

Especificar directorios de datos separados#

Puedes ahora usar dos iconos para abrir rápida y fácilmente diferentes billeteras simultáneamente desde su escritorio. Ambas billeteras mantienen copias enteras y separadas de la cadena de bloques, la cual puede usar mucho espacio en disco. Para uso mas eficiente del espacio en disco, considere usar un SPV o una billetera «liviana» como Dash Electrum para mantener separadas múltiples billeteras sin mantener una copia completa de la cadena de bloques.

Dos instancias de Dash Core ejecutándose simultáneamente#

KeePass#

Advertencia

KeePass support was removed in Dash Core 18.0.0. Details can still be found in previous versions of this documentation.
