Hi it’s Keir Finlow-Bates here, and today I
want to start a series of five videos in which I look at a sample blockchain
system that can be used to illustrate a number of the different features and
problems that are faced in the blockchain space. So I’ll start off in
this video by defining the system and it’s a blockchain to allow people to
play games of chess against each other. So I think chess is a very good use case
in terms of providing an example because it has a very clearly defined consensus
system namely the rules of chess – not just how the pieces are allowed to move
or how they’re set up on the board or even how a win or a draw loss is
defined, but in the social scene surrounding chess, namely that there are
time limits on moves and also in the ranking system for chess, which is the
Elo ranking system whereby as you play games of chess against other players in
a league your ranking will actually go up or down depending on whether you win
or lose, and in relation to how strong the opponent you are playing against is.
So there’s this whole system not just of the formal game of chess, but also of the
ecosystem surrounding chess and I think that translates very nicely onto a
blockchain, in that players can be identified by their blockchain addresses,
they can actually (if such a system was to be implemented) they can actually make
challenges against other players on the blockchain which would then be accepted,
and the game itself could be played on the blockchain with the block times
ensuring that moves are made in time or otherwise the game is forfeited.
so that’s a kind of consensus protocol and incentivization system for
chess, and in the next video I’ll look at how by tacking a cryptocurrency or
digital token on to the game you can actually add an extra dimension to the
chess game, namely one of bringing real value to it.
So look out for that video tomorrow. I hope the introduction has
made sense to you, and if you have any more queries or questions or would like
me to expand on the basic system please ask below in the comments,
and I’ll respond as soon as I can. Thanks for watching and see you in the next
video. Bye for now!
