<p>As specified in <a id="id12" class="footnote_reference" href="#zip-0207">6</a>, a funding stream is active for a span of blocks that includes the block at its start height, but excludes the block at its end height.</p>
<p>The funding streams are defined for Testnet are identical except that the start height of each stream is the activation height of ${NU4} on Testnet, i.e. xxxxxxx.</p>
<p>Note: on Testnet, the activation height of ${NU4} will be before the first halving. Therefore, the consequence of the above rules for Testnet is that the amount sent to each Zcash Development Fund recipient address will initially (before Testnet block height 1046400) be double the corresponding initial amount on Mainnet. This reduces to the same amount as on Mainnet, from Testnet block heights 1046400 (inclusive) to 2726400 (exclusive).</p>

<p>The funding stream mechanism allows for this option by adding a funding stream corresponding to each direct grantee, with addresses generated by ZF. In this case the total amount of funding streams assigned to direct grantees MUST be subtracted from the funding stream for the remaining <strong>MG slice</strong> (or, if all Major Grants are direct, replace the funding stream for the <strong>MG slice</strong>).</p>
<p>For each network upgrade after ${NU4} requiring modifications to the set of direct grantees, a separate ZIP would be published specifying those modifications.</p>
