To have a section to start a contest following my ideas on post "Apriori hash of the number of shifts in a list"
https://bitcointalk.org/index.php?topic=152793.0To start a contest you would only have to send to the designated blockchain.info bitcoin address for that matter the number of blocks that you wanted your contest to last.
You would send that number of blocks as satoshis and a new game would start on the next block creation that would last for as many block creations as the satoshis you sent.
For every amount you sent a separate game would be created, with a new contest number, like #1234567.
To see information about that contest you would only have to type: blockchain.info/contests/1234567, for instance.
The page would publish the hash of a very long random number generated by blockchain and kept secret, and list participations, line by line, with the corresponding position number of them.
It would also say the number of the block when the contest would be closed (set by the satoshis sent by the owner of the game).
It would be up to the owner of the bitcoin address of the contest, to say what the winner could claim. The page of the contest would just publish the information, pretty much like a random.org to enable people to run their own contests as they wish relying on the trust that people may give them.
It would make all calculations, list information and publish results, that would be completly verifiable and provably fair.
