Their marketing is amazingly awful. Nice tech, but they really need to fire (or hire) someone for marketing. Right now it looks like they just try to go with press releases and hope crypto sites pick up the news ... but since the coin isn't on the hype train to begin with, not many even bother to mention it.

I also don't get why they don't alter their release pattern so rating sites list them higher. Lior had a blog post about this and it is kind of ridiculous, where rating sites look at github (which Jelurida doesn't even use) and updates (even if meaningless) to convey dev activity ... so ardor is lower ranked than coins that basically have no dev teams at all. Yet Jelurida sticks with delayed updates and releases  code all at once because they are afraid others will steal it early. Of course this results in less hype and lower ratings, even if they release a ton more stuff than some higher rated coins. The simple way to look at it is -- Jelurida needs to play the hype/marketing game like everyone else, yet so far they haven't.

As for the android node stuff, that could be interesting if they ever go with an IOT partner. It'd be amusing if my refrigerator or other oddball devices could stake coins.

Well there aren't so many new childchains in the history of ardor yet, and I do not see a reason why the number of childchains may skyrocket in the future. In the best case, I would guess that a maximum of 1 - 2 childchains a year might come to the platform. Also with pruning and snapshot I do not see a future where the ARDOR Blockchain might grow faster, than cheap storage becomes available.
I hope the devs can deliver the snapchat function in the first half of 2020 to the mainnet. And hopefully they will do some marketing after that  

My apologies, autocorrect on my smartphone...... It is not snapchat, it is snapshot 
The 1-2 per year is based on the the history of ARDOR. In the beginning I would have also thought that the number of childchains may be higher, but it seems, that companies are not (yet) interested in ARDOR and that the previous marketing of Jelurida is not enough.

Ardor will be added to the new Hanbitco exchange, ARDR token trading will begin on November 21, and now the announcement itself from the exchange

Jelurida reported that Ardor blockchain in Java is now able to work as a full-fledged node on Android OS

From where I sit... it will not have any effect as ARDOR staking reward  is very small compared to say SNR. Only wide use of  BaaS offered by Ardor platform will surge it .

a video was released about the future of blockchain, as well as what is multi-chain architecture and an overview of the Ardor platform https://www.youtube.com/watch?v=RexdCIBEuGg&feature=youtu.be

Tech question: Can I run two Ardor (NRS) instances (on the same tcp ports) on one server, if that server has two real IPs ?

Of course I know, that I can distinguish both instances in `nxt.peerServerHost' and `nxt.MyAddress' directives in nxt.conf configuration file.

But it will not work for OpenAPI instance, as `nxt.ApiServerHost' directive should be (with the value) 0.0.0.0 (otherwise Ardor Explorer cannot recognize this peer as OpenAPI one).

Thnx for any hint.

Great. Anyway - some changes by the ARDR/NXT reward algorithm ? I see on the blockchain, that some reward transactions are still running, but I didn't received any reward transaction for almost 24hrs, and normally I get several reward transactions per a day. Sure, it can be a statistical coincidence, but I think it's unlikely. Does somebody knows any details ?
