This project is an implementation of the classic Battleship game as a secret contract, flavored as "Battle Sheep" just because I thought it'd be more fun 🎉

At the moment this is only an implementation of the secret contract part, without a GUI. The secret contract tries to demonstrate solutions to several of the theoretical attacks described in the encryption specs document.

This includes:

• Since in the current version of the testnet we can not verify the message sender, all queries and handles that require authentication check for a user-defined secret, that other users can not forge, and the contract does not expose.
• In order to prevent offline attacks, where one of the players tries all the moves offline to see their effect on the board, which would allow them to scan the entire board and discover all enemy sheep silently, each move requires confirmation from the other player before its effect is processed. This is basically a way of achieving relevant-scope-consensus about the moves on the board, preventing unauthorized disclosure of secrets.
• Some of the storage patterns try to avoid side-channel attacks, although admittedly others don't.
