\subsection{Payment of Funding Streams} \label{fundingstreams}
|
||||
|
||||
The \fundingStreams are paid by \transparent outputs in the \coinbaseTransaction, to
|
||||
one of a pre-defined set of \transparent addresses, depending on the \blockHeight.
|
||||
|
||||
The $i$th \fundingStream is defined by three constants:
|
||||
|
||||
\begin{formulae}
|
||||
\item $\FundingStreamFraction{i} \typecolon \Rat$
|
||||
\item $\FundingStreamStartHeight{i} \typecolon \Nat$
|
||||
\item $\FundingStreamEndHeight{i} \typecolon \Nat$.
|
||||
\end{formulae}
|
||||
|
||||
Define $\HeightForHalving(\HalvingNum)$ so that $\HeightForHalving(\HalvingNum) = \BlockHeight$
|
||||
where $\BlockHeight$ is the least \blockHeight such that $\Halving(\BlockHeight) = \HalvingNum$.
|
||||
|
||||
Define:
|
||||
|
||||
\begin{formulae}
|
||||
\item $\FundingStreamAddressChangeInterval := \PostBlossomHalvingInterval / 48$
|
||||
\item $\FundingStreamAddressPeriod(\BlockHeight) :=
|
||||
\floor{\hfrac{\BlockHeight - (\HeightForHalving(1) - \PostBlossomHalvingInterval)}{\FundingStreamAddressChangeInterval}}$
|
||||
\item $\FundingStreamAddressIndex{i}(\BlockHeight) :=$
|
||||
\vspace{-0.5ex}
|
||||
\item \tab $1 + \FundingStreamAddressPeriod(\BlockHeight) - \FundingStreamAddressPeriod(\FundingStreamStartHeight{i})$.
|
||||
\end{formulae}
|
||||
|
||||
The number of \transparent addresses per \fundingStream is therefore:
|
||||
|
||||
\begin{formulae}
|
||||
\item $\FundingStreamNumAddresses{i} := \FundingStreamAddressIndex{i}(\FundingStreamEndHeight{i})$.
|
||||
\end{formulae}
|
||||
|
||||
Let $\FundingStreamAddressList{i}_j$ be the $j$th address for the $i$th \fundingStream.
|
||||
Each address representation in $\FundingStreamAddressList{i}_{\oneto{\FundingStreamNumAddresses{i}}}$
|
||||
denotes a \transparent P2SH multisig address.
|
||||
|
||||
Let $\RedeemScriptHash_i(\BlockHeight)$ be the standard redeem script hash, as defined in
|
||||
\cite{Bitcoin-Multisig}, for the P2SH multisig address with Base58Check form
|
||||
given by $\FundingStreamAddressList{i}_{\,\FundingStreamAddressIndex{i}(\BlockHeight)}$.
|
||||
|
||||
Recall from \crossref{subsidies} the definition of $\FundingStreamValue{i}$.
|
||||
|
||||
\consensusrule{
|
||||
In each \coinbaseTransaction for \blockHeight $\BlockHeight$, for every
|
||||
$i \in \range{1}{\MaxFundingStreams}$ such that $\FundingStreamValue{i}(\BlockHeight) \neq 0$,
|
||||
the \transaction{} \MUST include at least one output that pays exactly
|
||||
$\FundingStreamValue{i}(\BlockHeight)$ \zatoshi with a standard P2SH script
|
||||
of the form \ScriptOP{HASH160} \;$\RedeemScriptHash_i(\BlockHeight)$\; \ScriptOP{EQUAL}
|
||||
as its $\scriptPubKey$.
|
||||
}
|
||||
|
||||
\begin{pnotes}
|
||||
\item The \fundingStream addresses are not treated specially in any other way, and
|
||||
there can be other outputs to them, in \coinbaseTransactions or otherwise.
|
||||
In particular, it is valid for a \coinbaseTransaction to have
|
||||
other outputs, possibly to the same address, that do not meet the criterion
|
||||
in the above consensus rule, as long as at least one output meets it.
