* The `dsa` message contains a collateral transaction
* This transaction uses a collateral input created in the [Wallet Preparation](#privatesend<!--noref-->-wallet<!--noref-->-preparation) phase
* The collateral is a signed transaction that pays the collateral back to a client address minus a fee of 0.001 DASH
* As of protocol version 70209, the `dsa` message indicates how many inputs will be provided to the pool when Spork 6 is active
_**Step 3 - Queue**_
* A masternode broadcasts `dsq` messages when it starts a new queue. These message are relayed by all peers.
* As of protocol version 70209, when Spork 6 is active the `dsq` message indicates how many inputs must be provided to participate in the pool.
* Once the masternode has received valid `dsa` messages from 3 clients (`nPoolMaxTransactions`), it sends a `dsq` message with the ready bit set ([Dash Core Reference](https://github.com/dashpay/dash/blob/e596762ca22d703a79c6880a9d3edb1c7c972fd3/src/chainparams.cpp#L173))

* As of protocol version 70214, mixing sessions have a variable number of participants defined by the range `nPoolMinParticipants` (3) to `nPoolMaxParticipants` (5). Prior protocol version mixing sessions always contained exactly 3 participants
* Once the masternode has received valid `dsa` messages from the appropriate number of clients (`nSessionMaxParticipants`), it sends a `dsq` message with the ready bit set
* Clients must respond to the Queue ready within 30 seconds or risk forfeiting the collateral they provided in the `dsa` message (Step 1) ([Dash Core Reference](https://github.com/dashpay/dash/blob/e9f7142ed01c0d7b53ef8b5f6f3f6375a68ef422/src/privatesend<!--noref-->.h#L23))
_**Step 4 - Inputs**_
* The collateral transaction can be the same in the `dsi` message as the one in the `dsa` message (Step 1) as long as it has not been spent
* Each client can provide up to 9 (`PRIVATESEND_ENTRY_MAX_SIZE`) inputs (and an equal number of outputs) to be mixed ([Dash Core Reference](https://github.com/dashpay/dash/blob/e596762ca22d703a79c6880a9d3edb1c7c972fd3/src/privatesend<!--noref-->.h#L28))

* This is the only message in the PrivateSend process that contains enough information to link a wallet's PrivateSend inputs with its outputs
* This message is sent directly between a client and the mixing masternode (not relayed across the Dash network) so no other clients see it
