Hive-Engine is the most used Hive sidechain supporting smart contracts and tokens. Also it's already integrated and used by Splinterlands and most players are already familiar with it.
Why a DIESEL POOL?
Using Hive-Engine based "Diesel Pool" has several interesting benefits. Hive blockchain doesn't require fees for transactions. Also diesel pools allow for Reward Pools to those who help provide Liquidity into the Liquidity Pools. (we explain the benefit of this below). Diesel Pools have been used to swap hundreds of millions of dollars of tokens and are accessible to all our Hive based users. We believe we can also integrate user interfaces into our websites to make adding to these pools and swapping easier.
