The existing difficulties include, amongst other things, issues around
the deduction of third-party charges from winnings and the lack of availability of
payment methods in some territories. However, chief among the issues that
blockchain technology can potentially address are the issues of fairness and
transparency. In a traditional online gambling environment, players have no way of checking the fairness of any draw or result. They have to rely solely on trust and whatever checks and audits are in place under the regulatory regime applicable to the operator. Similarly, players typically cannot verify for themselves that winnings in a lottery are distributed honestly.
