I've gone into more detail in another post.

In summary: poorly designed website, copy and paste mistakes in the white paper, unable verify the team, cannot verify their claims about contracts and Chinese government support, no evidence of work/productivity (github), controlling too many coins, fake news stories, unconvincing "team" photos and videos (the CEO comes across as a budget actor struggling to read a cue card - you can see the shadow of the cue card), hired a privacy service (associated with numerous scams) to hide the domain registration details, aggressive shills that boot people from Slack & Reddit for asking reasonable questions, pressure tactics (buy more for a master node before it's too late [or we do a runner]), obviously paid shills on twitter and Reddit (hype comments with little substance) etc.

Nothing about it feels right.

I've probably spent far too much time talking about these things.

I strongly suspect that Walton Chain is a scam.

At best, as you say, a very amateurish team and, in my opinion, recklessly hyping and overpromising.

Would a team of experienced individuals, including a form VP of Samsung, be this amatuer?

Either way, I'd be very surprised if a product materialises.

$180,000,000 market cap with no product, no tangible evidence of work and many unsubstantiated claims.

The shills are hyping and talking about a market cap of $1billion this year.

I feel I have a duty to express my concern.

Jin Xiji (chinese name) / Kim Suk-Ki (korean name), the chief scientist for WaltonChain:

Here, he is the Chief Scientist for Silicon Group (who won the Jin Jiang competition), and who sponsors Walton Chain: http://www.xmsilicon.com
Looking around on that site, it looks like they pretty much ARE WaltonChain. Mo Bing and Chen Zhangrong are also directors there: http://www.xmsilicon.com/col.jsp?id=130
On this page, the picture of the office looks to be the same one in the WaltonChain tour video, which further substantiates WaltonChain's link to Silicon Group: http://www.xmsilicon.com/col.jsp?id=104
Or how about Chen Zhangrong, who you're labeling "budget actor"? An article on him when he was (or still is) president of Tianyu International Group, Co. Ltd.: http://news.china-ef.com/471356.html
There are also countless news articles about the Walton team & their partnerships:

Here is one about their cooperation with Septwolves: http://tech.china.com/article/20170824/2017082452565.html

and there's likely much more that I missed over.
Mate, their credentials are definitely legitimate.
