Diesel pools for all these hive-engine tokens would be super awesome. Part of me hopes that all the projects phase out all those silly token inflation things they call "miners" and give that inflation to liquidity providers instead because they're actually giving utility.

But from what I understand projects will be able to incentivize liquidity by allowing inflation of the token to go to the liquidity providers. Exactly the mechanics of that we dont know ... but seems like a pretty easy concept.
However I'm guessing the most likely pairing will be swap.hive and for that you're having to give your hive to hive-engine and trust them to keep it safe, which I think we're willing to trust them but we just want a bit more details about safety protocols.
