<br />
In order to fufill the design criteria of voting pools, change outputs generated from withdrawal transactions must be sent to deterministically-generated addresses.<br />
<br />
==Procedure==<br />
<br />
Any change generated by a withdrawal transaction is sent to an address in the [[Keyset (voting pools)#Series|active change series]]. Addresses in the change series are differentiated from addresses in the deposit series by presenting the pubkeys in the output scripts in reverse standard order.<br />
Example<br />
<br />
Assume voting pool has just started with deposit series 1 being hot, and deposit series 20 being active. Change outputs created from withdrawals taken from deposit series 1 will be sent to change series 20. The standard order of the xpubs in series 20 is: y<sub>20</sub>, z<sub>20</sub>, w<sub>20</sub>.<br />
<br />
The first three change-generating transactions will use the following output scripts:<br />
<br />
<code>OP_2 w<sub>20</sub>(1) z<sub>20</sub>(1), y<sub>20</sub>(1) OP_3 OP_CHECKMULTISIG</code><br />
<br />
<code>OP_2 w<sub>20</sub>(2) z<sub>20</sub>(2), y<sub>20</sub>(2) OP_3 OP_CHECKMULTISIG</code><br />
<br />
<code>OP_2 w<sub>20</sub>(3) z<sub>20</sub>(3), y<sub>20</sub>(3) OP_3 OP_CHECKMULTISIG</code><br />
<br />
Notice again that the servers are presented in reverse standard order, to indicate the script is for a change address, not a deposit address.<br />
