\section{Consensus and State Management}


\subsection{Lux Consensus Integration}

Hanzo integrates the Lux consensus engine (Wave family) with sled database backend for high-throughput finality.

\subsubsection{Wave Consensus}

Key parameters:
\begin{itemize}
\item Sample size $k = 20$
\item Quorum size $\alpha = 15$ ($75\%$ threshold)
\item Decision threshold $\beta = 20$ consecutive successes
\item Confidence threshold: 32 blocks for finality
\end{itemize}

\subsubsection{Sled Database}

Lock-free embedded database with:
\begin{itemize}
\item Atomic operations via Compare-And-Swap
\item Zero-copy reads
\item Optimized for SSD workloads
\item Built-in CRDT support for distributed state
\end{itemize}

Performance characteristics:
\begin{itemize}
\item Local throughput: 9M+ blocks/second
\item Write latency: sub-millisecond (SSD)
\item Read latency: microseconds (hot cache)
\item Storage efficiency: $<$1KB per block header
\end{itemize}

\subsection{Scheduler Daemon}

On-node compute scheduling with blockchain integration:

\begin{algorithm}
\caption{Scheduler Daemon Main Loop}
\begin{algorithmic}[1]
\STATE Initialize ResourcePool with node capacity
\LOOP
    \STATE pending $\leftarrow$ FetchPendingDeployments()
    \FORALL{deployment $d$ in pending}
        \IF{ResourcePool.CanAllocate($d$.requirements)}
            \STATE Allocate resources
            \STATE runtime.deploy($d$)
            \STATE RecordToBlockchain($d$.id, timestamp)
        \ELSE
            \STATE Enqueue($d$) for next cycle
        \ENDIF
    \ENDFOR
    \STATE CollectMetrics()
    \IF{block\_number $\mod$ billing\_interval $= 0$}
        \STATE ProcessBilling()
        \STATE MintTokens()
    \ENDIF
    \STATE Sleep(block\_time)
\ENDLOOP
\end{algorithmic}
\end{algorithm}
