Officially they not launched any block explorer in neucoin.org or forum
Doesn't matter. The unofficial BE shows what they don't want you to see. That's the reason why there isn't an official one.
You should ask yourself:
Why are there only 100 addresses with more than 3 billion of Neucoins?
Where are all the addresses of the thousands who bought into the public ICO?
The problem is... these are the people behind Neucoin:

I deleted the specifications... but you can see them all here:
http://www.neucoin.org/en/wiki/#teamTogether that are 50 persons. Maybe some of them stepped back, but it doesn't matter if there are 5 more or less. Everybody should have at least one Neucoin-Address, right? If everybody would have just two addresses that would be already 100 addresses, plus two exchanges.
And just 100 addresses holding more than 3 billion of the total supply which is in fact the total supply. The rest is some tipping, some more addresses where the staked coins go to, and some poor guys who really bought into the ICO but hopefully didn't invest much.
Another scenario: The guys above are just names but not really holding Neucoin. Maybe some of them gave BTC because they have enough, and Dan holds their Neucoins. But you can be sure that everybody of the core-team has more than just one address, more than just two or three. It's normal to have multiple addresses. And it's normal that exchanges not just have one address for a coin.
Either way, the Conclusion is: There is no public. Maybe 50-100... They never collected 4000 BTC from the public and if they wouldn't manipulate the market there wouldn't be any volume.
