Game: research how to do verifiable game architecture

[pkieltyka]

In light of the new game architecture thats based on an event sourced architecture implemented as a redux state machine, each committed player action will be signed by a user and later uploaded to IPFS, where another observer could easily replay and verify game-play. As we iterate on this architecture to move towards further decentralization, there remains some questions:

1. How to handle game logic versions for a game? that is, a game will naturally change over time, but we should be able to replay historical game moves on an older version of a game

2. How to handle trusted game logic source for a version? perhaps just hashing a source tree or docker image of a dist file is sufficient? and we have a verifier run as a docker container? assuming its byte-for-byte the same, and we can reply on a hash. But, can this be forged? is there any good reason for someone to forge it and it not being caught by one of the 3 parties in a game? (PvP via server)

3. Source of truth for game rules? (same as the game version)

4. Other...?
