Steem has 231,900,775 coins powered up.

Hive has 165,365,256 coins powered up.

This is a difference of 40%. Potentially our votes are 40% more powerful on Hive simply because of this difference. However, it doesn't take into account the huge accounts like @steemit that are sitting at 100% voting power, not leeching the reward pool (at the moment). However, there are also accounts like haejin who are leeching the reward pool of Steem and not Hive. Unfortunately, I'm not running a node and can't really track these numbers myself.

A test I can run is simply upvoting content on both platforms. On Hive, an 84% upvote with 40k stake creates 0.5 Hive per vote. (67k per 1 Hive) On Steem, an 83% upvote with 26.5k stake creates 0.293 Steem. (75k per 1 Steem). So we see that roughly Hive votes are worth 12% more than Steem votes on a coin by coin basis. This also implies that you get more vests for powering up a Hive coin than you do Steem because there is less competition for them.

Of course these inflation numbers are being estimated by frontends SteemPeak and Peakd, so who knows.

I found a script I created in September 2018 (wow) while I was trying to learn the dsteem API.

It still works.

I've modified this script slightly to see if it also works with Hive.
It does.

Hive

Steem

The point of the script was simply to import some basic information on the given account and retrieve the generic information of the blockchain at large

client.database.getDynamicGlobalProperties()

I find this script somewhat interesting because when I created it things like sps_fund_percent didn't exist. The SPS did not exist when I created this code. Clearly the node API was changed to include variables like this during that hardfork.

Yes, I know you don't care.

Even more interesting is that the number of vests you get per coin is pretty much identical on both platforms. Hive has way less vests than Steem does. It was my understanding vests were less of a dynamic resource than that. I guess I still don't know how it works fully. Perhaps @blocktrades made a one time modification when we forked over. Not sure.

Dolphin (10M VESTS)

It takes 5116 Hive to become a dolphin.
It takes 5113 Steem to becomes a dolphin.

Conclusion

Less coins siphoning money from the reward pool means your stake has more power over inflation. The more accounts that have voting power sitting at 100%, the more your vote is worth. The more content that gets flagged, the more your vote is worth.

The economics of Graphene blockchain technology are complex.

Maybe one day I'll figure it out.
