\begin{itemize}
|
|
\item \textit{Risk} is a popular strategy board game.
|
|
\item It is played on a single board, depicting a world map, partitioned into regions.
|
|
\item A player owns a region of the map by stationing troops within the region.
|
|
\item Players fight for regions by gambling some of their troops against the troops in the other player's region.
|
|
\end{itemize}

\begin{frame}{Risk}
|
|
\begin{itemize}
|
|
\item \textit{Risk} has a variant called "fog of war".
|
|
\item In this variant, players can only see the number of troops stationed within regions they neighbour.
|
|
\item This variant is therefore only played online, in a \textbf{trusted setup}.
|
|
\end{itemize}

\begin{frame}{Proposition}
|
|
\begin{itemize}
|
|
\item Play fog-of-war Risk in an untrusted setup.
|
|
\item In the untrusted setup, the same guarantees should be made as the trusted setup, but on a peer-to-peer network.
|
|
\end{itemize}

\begin{frame}{Rationale}
|
|
\begin{itemize}
|
|
\item \textbf{Federation} \begin{itemize}
|
|
\item Federated platforms can have longer lifespans than centralised platforms.
|
|
\item Federated platforms are more resistant to censorship and can help promote anonymity and privacy.
|
|
\item Federated platforms encourage user freedom.
|
|
\end{itemize}
|
|
\item \textbf{Security} \begin{itemize}
|
|
\item Constantly looking for ways to secure against threats specific to federated and decentralised infrastructures.
|
|
\item Security issues can be devastating even to decentralised infrastructures.
|
|
\end{itemize}
