\section{Threat Model}
|
|
|
|
|
|
\begin{definition}[Adversary Capabilities]
|
|
The adversary can:
|
|
\begin{itemize}[leftmargin=2em]
|
|
\item Observe all messages on all chains (public blockchains).
|
|
\item Submit arbitrary messages to any chain's receive function.
|
|
\item Corrupt up to $t-1$ of $n$ MPC attestation nodes.
|
|
\item Cause network partitions between chains (delay messages arbitrarily).
|
|
\item Revert transactions on source chains (before finality).
|
|
\end{itemize}
|
|
\end{definition}
|
|
|
|
\begin{definition}[Security Goal]
|
|
No adversary can cause the release of assets on a destination chain without a corresponding, finalized, unconsumed deposit on the source chain.
|
|
\end{definition}
