Abstract: Disclosed are various embodiments directed towards devices, systems, and methods involving the use of cryptocurrency in player tracking and reward systems. A player may deposit cryptocurrency into a player account for the purpose of funding casino play. The player may also withdraw funds from the player account in the form of cryptocurrency. The player may also redeem player loyalty points for cryptocurrency accepted by various merchants. The casino's cryptocurrency may be a wrapped version of a public cryptocurrency and may mimic a public stablecoin. The cryptocurrency held by the casino may be maintained on an enterprise blockchain or in a distributed ledger system in which multiple casinos participate to provide an efficient common private cryptocurrency in any of the participating casinos with a minimal cost per transaction.

Abstract: The description provides processes for the regio and stereospecific synthesis of polyprenylatedquinone derivatives, such as Vitamin K1, K2 and Ubiquinone, exploiting dithioacetals, especially 1,3-dithiane, mediated Umpolung chemistry which works along a new concept “Inhibiting resonance delocalization (IRD)” to overcome isomerization generated due to delocalization of allyliccarbanion on the ?-electron cloud of an allylic systems by the conventional synthesis.
