PrivateSend e InstantSend


This documentation describes how to use Dash Core to send Dash with enhanced privacy.


PrivateSend, released as DarkSend in 0.9-RC4 of the DarkCoin client and rebranded to PrivateSend in May 2016, is a trustless method of running a sequence of transactions (known as «mixing») such that an external observer is unable to determine the source of funding when a PrivateSend transaction is created. This gives your Dash the same privacy properties as cash withdrawn from an ATM, for example. The mixing and denomination process is seamless, automatic, and requires no intervention on the part of the user. The current implementation of PrivateSend in the Dash Core wallet allows any amount of Dash to be mixed for later use in PrivateSend transactions. PrivateSend is also available in the Dash Electrum wallet.

Knowledge of the exact number of rounds of PrivateSend mixing used in any given PrivateSend transaction has a quantifiable effect on the confidence an adversary may have when attempting to guess the source of a PrivateSend transaction. For this reason, the recommended (and default) number of rounds of PrivateSend mixing is set to four, and some inputs may be mixed by additional rounds to further improve privacy.

  1. Open your Dash Core wallet, go to Settings and select Options. Go to the PrivateSend tab.

  2. Next to PrivateSend rounds to use, enter a value between 1-16. Each round of PrivateSend performs one denominated fund mixing transaction. Higher numbers of rounds increase your overall level of privacy while decreasing the chance of detection via node collusion. 16 is the highest number of rounds currently available.

    NOTA: para evitar el abuso del sistema, un promedio de una de cada diez rondas de mezcla de masternode conlleva a una comisión de .0001 DASH.

  3. Enter a Target PrivateSend balance. This value provides a lower boundary on the final amount of funds to be mixed. Depending on how the client splits your wallet balance, you may end up with denominated inputs whose sum total is slightly greater than the target amount.

  4. Haz click en OK para salvar los ajustes.

  5. PrivateSend está deshabilitado de forma predeterminada cuando abres la billetera. Solo se iniciará después de establecer el número de rondas y el número de Dash para mezclar, en la configuración haz click en Iniciar mezcla en la pestaña Información general de tu billetera.

Iniciar mezcla

El proceso de PrivateSend se inicia haciendo click en el botón Iniciar mezcla en la pestaña Información general de la billetera Dash Core. La mezcla es posible una vez que se han cumplido las siguientes condiciones:

  • The wallet contains sufficient non-mixed funds to create the minimum required denominated values
  • El usuario no ha deshabilitado PrivateSend en el cuadro de diálogo Opciones
  • The target value for mixed Funds in the Options dialog is greater than zero

Si tu billetera está encriptada (muy recomendado), se te pedirá que ingreses su contraseña de la billetera. Activa la casilla Solo para mezclar mediante PrivateSend para desbloquear la billetera solo para mezclar.

Esto desbloqueará tu billetera y comenzará el proceso de mezcla de PrivateSend. La billetera permanecerá desbloqueada hasta que se complete la mezcla de PrivateSend, en cuyo punto se bloqueará automáticamente.

PrivateSend comenzará a crear transacciones y tu saldo de PrivateSend aumentará gradualmente. Este proceso puede tomar algo de tiempo, así que se paciente. Puedes supervisar el proceso con más detalle, como se describe en la siguiente sección.

Any of the following actions will interrupt the mixing process. Because the transactions are atomic (they either take place completely, or do not take place at all), it is possible to safely interrupt PrivateSend mixing at any time.

  • Hacer click en el botón Detener mezcla en la pestaña Descripción general
  • Cerrar el cliente antes de que se complete la mezcla de PrivateSend
  • Envío de fondos de PrivateSend desde la billetera antes de completar las rondas de PrivateSend
  • Deshabilitar PrivateSend antes de que se complete el proceso

Monitorear la mezcla

If you want to monitor PrivateSend in more detail, you need to enable some advanced features of the wallet. Go to Settings, select Options and go to the Wallet tab. Check the Enable advanced PrivateSend interface checkbox. This will allow you to monitor progress and see which individual operations PrivateSend is carrying out in the background.


Monitorear el proceso de PrivateSend

Since PrivateSend mixing creates a lot of new address keys to send and receive the mixed denominations, you may receive a warning when the number of remaining keys runs low. This is nothing to be worried about, since the wallet will simply create more keys as necessary. However, these keys will not exist in any previous backups of your wallet. For this reason, it is important to backup your wallet again after mixing is complete.

También puedes monitorear el progreso de PrivateSend al ver las transacciones creadas por el proceso de mezcla en la pestaña Transacciones.


Transacciones creadas por PrivateSend en la pestaña Transacciones

La siguiente tabla describe las transacciones relacionadas con PrivateSend que se muestran en la columna de la pestaña Transacciones:

Tipo de transacción de PrivateSend Descripción de transacción
PrivateSend hace entradas colaterales (Mezclando) Los fondos de la billetera se transfirieron a insumos de garantía que se usarán para realizar pagos de garantías. Esto se hace para minimizar la trazabilidad de las garantías.
PrivateSend crea denomiaciones (Mezclando) Los fondos de la billetera se dividen en denominaciones de PrivateSend (Paso 1 aquí)
PrivatSend Denomina (Mezclando) Una transacción fue enviada a un masternode para participar en una sesión de mezcla (Paso 3 aquí)
PrivateSend pago de garantías (Mezclando) Se reclamó la garantía de la sesión de mezcla. Esta comisión se cobra en ~ 10% de las sesiones de mezcla para evitar los ataques de spam.
PrivateSend (Gasto) Se usaron fondos mixtos para enviar un pago a alguien. Nota: A diferencia de los 4 tipos de transacciones anteriores, esta no es una transacción de proceso de mezcla.

You can also use the coin control feature to view which addresses hold mixed denominations ready to be used for PrivateSend transactions. Go to the Send tab of your wallet and click Inputs to view the possible input addresses for your transactions. You can see how each address holds given denominations of mixed Dash, and how many rounds of mixing have been completed. This is to ensure that an efficient combination of addresses can be used as inputs in PrivateSend transactions without too much change, since amount in a PrivateSend transaction must be rounded up to completely spend all inputs. The current minimum balance for an input used in a PrivateSend transaction is 0.00100010 DASH.

Pago con PrivateSend

You can only use PrivateSend for payments once you have mixed enough Dash to make up the amount you are trying to send. Because the mixing process takes time, it must be done in advance before you create the send transaction. A PrivateSend transaction is effectively the same as any other transaction on the blockchain, but it draws only from input addresses where the denomination has previously been mixed to ensure privacy of funds. Because several input addresses are usually required to make up the amount you are trying to send, a PrivateSend transaction will usually take up more space (in kilobytes) on the blockchain, and therefore will be charged a slightly higher fee.

To send a payment using PrivateSend, go to the PrivateSend tab of the Dash Core wallet. The balance displayed is your PrivateSend balance instead of the total balance as shown on the Send tab. You can then enter the Pay To address, Label, Amount and click PrivateSend. Your payment will be rounded up to completely spend the lowest possible denomination of mixed balance available (currently to the nearest 0.001 DASH). You will be prompted to enter your password and receive a detailed breakdown of the fee structure for PrivateSend before sending.

Like all Dash transactions, PrivateSend transactions are composed of a number of inputs and one or more outputs. PrivateSend transactions do not use change addresses, so any remaining Dash will be spent on the transaction fee.

Due to the probabilistic nature of the PrivateSend mixing process, increasing the number of inputs in a transaction may marginally reduce privacy. For this reason, using PrivateSend is not recommended for users requiring a high level of privacy. While it is not possible to link a PrivateSend transaction to a single source address with absolute certainty, using more inputs may make a transaction more vulnerable to different potential linking attacks.

You can reduce the number of inputs in a PrivateSend transaction by defining the transaction amount in such a way that it consumes your available input denominations more efficiently, or by mixing more Dash to ensure enough appropriately denominated inputs are available. Use the Coin Control function in the PrivateSend tab to view and select or deselect mixed UTXOs currently available for use as transaction inputs.



This documentation describes how to use InstantSend to instantly send funds to any other Dash user around the world. Since the release of InstantSend based on Long Living Masternode Quorums (LLMQ-IS) in Dash 0.14, the Dash network itself will attempt to generate an InstantSend lock for almost every transaction processed by the network, according to these rules. Unlike the prior implementation of InstantSend, which required a higher fee, LLMQ-IS locks transactions without any action taken by the user. For this reason, only the recipient needs to monitor the network for the transaction lock in order to be able to receive funds and process transactions with immediate settlement.

Dash InstantSend is supported by many wallets and vendors, including (but not limited to) the following:

  • Billetera Dash Core
  • Cartera Dash para Android
  • Cartera Dash para iOS
  • Mi billetera de Dash
  • Kraken
  • Bitrefill
  • y muchos más…

InstantSend Transactions

Since Dash 0.14, all user-facing interface options to create an InstantSend transaction have been removed, because all transactions are effectively InstantSend transactions. As before, the recipient is responsible for monitoring the network for the InstantSend lock and implementing user-facing logic and interfaces to continue with transaction processing after payment has been recieved. See the InstantSend Integration documentation for more information on how to monitor for InstandSend locks.
