What will arise of the Steem-Just partnership?

I think it should be called the "Just-Steemit partnership" ; -)

It's hard to guess how these pieces all fit together. It certainly seems like the Steemit wallet is going to be updated to support tron transactions, possibly including: staking, account creation and transfers. It also seems likely that there's some mechanism in development to support tron tipping and to distribute tron in addition to Steem for post rewards. I'm assuming that's just for authors, but could - conceivably - also pay curation rewards, too. As I recall, that's already all in github. No idea where those tron rewards will come from, though. Some sort of Tron smart contract, I guess?

The power down is even trickier. Steem Air-drops to Tron token holders? (once you have Tron in the wallet, it may be possible to do that...) Funding the upcoming Tron rewards? Creating a TRC20 token that's pegged to Steem? Collateral for some sort of JUST-based asset? Or they could just be moving it out of sight so they can continue to fund operations without triggering a panic every time they power down? No idea, but I am optimistic that it will be used in a productive way. I can understand why they didn't want to leave it sitting idle on the chain when it was only earning like 3% APR from blockchain inflation. With powered up funds, if you're not voting or delegating to someone who is voting, then the asset is sort-of wasted.

Like you, I was expecting to hear more about the Just-Steemit partnership before now. A whole lot of JUST hype came and went already. Since @steemitblog hasn't posted in almost 2 weeks, I wonder if they're in some sort of "quiet period"... It would be strange to announce a partnership before a quiet period, though.

In short, it's a whole lot of "I don't know" and a good bit of "eager to see what's coming".
