\section{Introduction} For a transaction in the FUCoin system we have to make sure, that either all operational participants commit the transaction or none of them. Each participant has one of two votes for the possible transaction: YES or NO. For the transaction to happen all participants have to vote YES, so a decision cannot be reversed. The init participant acts as the coordinator and sends a 'vote request' to all other participants. After a participant receives this request, it responds with either YES or NO. In case of NO the decision is already 'Abort'. If all participants vote YES, the coordinator decides 'Commit' and sends a commit message to all participants. Otherwise it sends an abort message to all participants that voted YES. \bigskip \\ \\ \\ \\ \includegraphics[width=1.0\textwidth]{pictures/TimelineCorrectTransfer.pdf}
