\item $\CanopyActivationHeight$ is different between \Mainnet and \Testnet.
\item On \Testnet, the \activationHeight of \Canopy will be before the first halving.
Therefore, the consequence of the above rules for \Testnet is that the amount sent to
each recipient \fundingStream address will initially (before \Testnet \blockHeight $1046400$)
be double the corresponding initial amount on \Mainnet. This reduces to the same amount
as on \Mainnet, from \Testnet \blockHeights $1046400$ (inclusive) to $2726400$ (exclusive).
\item The \blockHeights of \halvings are different between \Testnet and \Mainnet, as a
result of different \activationHeights for the \Blossom \networkUpgrade (which
changed the \blockTargetSpacing). The end height of these funding streams
corresponds to the second \halving on each network.
\item On \Testnet, the \activationHeight of \Canopy is 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
\blockHeight $1116000$) be double the number of currency units as the corresponding
initial amount on \Mainnet. This reduces to the same number of currency units as on
\Mainnet, from \Testnet \blockHeights $1116000$ (inclusive) to $2796000$ (exclusive).
