LP-217 & Cert profile modes; pipeline throughput model is parameterized by the chosen cert mode \\

\subsection{Wire format unchanged}
|
|
|
|
This LP introduces no new wire types. The block frame is the LP-186
|
|
block-VM frame; the cert is the LP-182 QuasarCert struct; the
|
|
round-digest is LP-077. Schema IDs are unaffected.
|
|
|
|
The pipeline-depth knob is a runtime config setting:
|
|
|
|
\begin{verbatim}
|
|
quasar:
|
|
pipeline_depth: 3
|
|
# default 3; minimum 1 (round-blocking);
|
|
# maximum bounded by leader-rotation-independence
|
|
\end{verbatim}
|
|
|
|
\section{Activation Marker}
|
|
|
|
\begin{verbatim}
|
|
activates: 2025-12-25T16:20:00-08:00
|
|
activates-unix: 1766708400
|
|
\end{verbatim}
|
|
|
|
Pipelined Quasar is the default at activation. Round-blocking
|
|
(\texttt{pipeline\_depth: 1}) remains a valid config for chains that
|
|
explicitly disable pipelining -- typically PQ-heavy chains where the
|
|
cert dominates the wall-clock and pipelining gains are negligible.
|
|
|
|
\section{Future Work}
|
|
|
|
\begin{itemize}[leftmargin=2em,nosep]
|
|
\item \textbf{LP-208} -- DAG mempool: leaderless tx-bundle production.
|
|
Composes with this LP -- DAG mempool replaces the Select stage's
|
|
mempool with a Narwhal-style DAG \cite{narwhal2022}.
|
|
\item \textbf{LP-209} -- Mysticeti ordering \cite{mysticeti2024}:
|
|
total-ordering of the DAG. Composes with this LP -- Mysticeti's
|
|
ordered output replaces the Select stage's tx-ordering substep.
|
|
\item \textbf{LP-210} -- Block-STM speculation across the pipeline:
|
|
pre-execute txs in the Select stage of block $N{+}2$ while $N$ is
|
|
being signed; commit on Sign of $N{+}2$.
|
|
\item \textbf{LP-211} -- Cross-shard atomic commit: the LP-205
|
|
pipeline at one shard interlocks with peer-shard pipelines via 2PC
|
|
over the cert layer.
|
|
\end{itemize}
|
|
|
|
\section{Backwards Compatibility}
|
|
|
|
None. The activation marker is at the genesis of the new final Lux
|
|
network. The pre-Quasar Edition Lux network is round-blocking by
|
|
construction and is a separate network out of scope.
