Additional question to upper one - is it possible to void, modify results, unsettle bets manually? Jurisdiction rules (Regulation organizations) will be applicable (which one?) to bookie or you will be some type of outlaw?
Node operators ("Witnesses" on the Peerplays blockchain) on the Peerplays blockchain will be able to manually report results (although we expect 99.9% of results to be handled automatically by the Oracle system). However, no single Witness will have the power to decide results/voids/bet settlements - it will require a majority (50%+1) of Witnesses to agree on results and bet settlements before they become accepted as "fact" by Bookie.
At launch, there will be no "resettlement" of bets. But a feature for Bookie is scheduled for release later in 2018 that will allow bettors to flag results they think are wrong and, if a certain number of users flag a particular result, Witnesses will be obliged to resettle the market manually to ensure correct resolution. More details on this later in the year.
