%------------------------------------------------ \begin{frame}{Bitcoin Mining Rewards} Two sources of income for Bitcoin Miners, a Block Reward and a User fee \newline \begin{center} Constant Miner Reward \begin{formal} ``The steady addition of a constant amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended.'' \begin{list}{$-$} \item{Satoshi Nakamoto} \end{list} \end{formal} \end{center} %Current reward is 6.5 Bitcoin \begin{center} Variable User Fees \begin{formal} %The incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction. Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free. ``The incentive can also be funded with transaction fees\ldots Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees'' \begin{list}{$-$} \item{Satoshi Nakomoto} \end{list} \end{formal} \end{center} %Currently ranges from 1\% to 2\% of reward, but has spiked to 25\% \end{frame}
