Is there any project updates especially on its development? I guess the community would love to hear any information and good news coming from the team that could inspire them to further support this project.
I can summarize what you can see in the public sphere after approx one year of time since their ICO start.
1) They have a mobile app "Datum Id" with "500+" users on Android as the android page shows
https://play.google.com/store/apps/details?id=org.datum.id2) They have a API which who knows how many people are using, could be none, could be some, but unlikely to be many due to the network size and number of data items stored in their network increases so slowly per day
3) They have a test network and a mainnet launched Sept 3rd
https://blog.datum.org/datum-mainnet-launch-announcement-15529c1599e54) They have a very low number of nodes in their network as you can see on their network explorer
https://explorer.mainnet.datum.org/5) They have a coin which is less than one pixel in US dollars from zero on coinmarketcaps graph as compared to its height of 238 pixels, if you like to count in pixels on the screen
6) Their coin is ranked at 786 on coinmarketcap now
That's the current status as you can see publicly. You can make your own inferences from the facts as given.
From a results driven point of view, the results of whatever they are doing seem poor.
