\section{Introduction}
|
|
|
|
|
|
Blockchain networks provide decentralized trust and auditability but face fundamental limitations in computational throughput, privacy, and cost. Public execution models expose all transaction data and intermediate states, making them unsuitable for privacy-sensitive applications such as financial risk models, medical data analytics, and proprietary machine learning inference \cite{ethereum-privacy,lux-appchains}.
|
|
|
|
Existing confidential computing solutions either rely on a single trusted execution environment (TEE) vendor \cite{secret-network,oasis-sapphire}, require complex multi-party computation protocols \cite{mpc-overview}, or depend on centralized off-chain workers \cite{iexec,truebit}. These approaches suffer from vendor lock-in, performance bottlenecks, or trust assumptions.
|
|
|
|
We introduce \textbf{Lux TEE Mesh}, a decentralized confidential computing layer that:
|
|
|
|
\begin{itemize}
|
|
\item Supports heterogeneous TEE hardware from multiple vendors (Intel, AMD, NVIDIA)
|
|
\item Provides cryptographic attestation verification on-chain via smart contracts
|
|
\item Scales linearly with worker nodes through gossip-based job distribution
|
|
\item Implements economic security through staking and fraud-proof mechanisms
|
|
\item Enables encrypted container execution with OCI-compatible images
|
|
\item Maintains separation of concerns: L1 handles ordering/fees, TEEs handle computation
|
|
\end{itemize}
|
|
|
|
\subsection{Contributions}
|
|
|
|
Our main contributions are:
|
|
|
|
\begin{enumerate}
|
|
\item \textbf{Unified TEE Attestation Framework}: A vendor-agnostic protocol for verifying attestation quotes from Intel SGX/TDX, AMD SEV-SNP, and NVIDIA GPU TEEs on-chain (Section \ref{sec:attestation})
|
|
|
|
\item \textbf{Encrypted Job Container Format}: An OCI-compatible container specification with hardware-sealed keys and Merkle-rooted execution traces (Section \ref{sec:containers})
|
|
|
|
\item \textbf{Gossip-Based Job Distribution}: A decentralized scheduler using ZAP gossip without global coordinators (Section \ref{sec:scheduler})
|
|
|
|
\item \textbf{Economic Security Model}: Staking, dynamic pricing, and fraud-proof mechanisms ensuring honest worker behavior (Section \ref{sec:economics})
|
|
|
|
\item \textbf{Developer-Friendly API}: Solidity SDK with callback patterns for async confidential computation (Section \ref{sec:dev-experience})
|
|
\end{enumerate}
