A detailed article uncovering Execoin's own implementation of Stealth addresses and future plans has been published at:

I like below:
1: currently we are considering and evaluating possible major changes to Execoin to mitigate over-inflation issue.
2: change PoW algo as well to the completely unique one, not being used in any of the coins existing on the market, thus making the upcoming Scrypt-N ASICs obsolete even before their release.
3:Within 1 week or so a fully functional beta version will be available in the mainnet.
4:in the nearest future we are going to port Electrum with Stealth to Android, create paper wallet with stealth addresses, port Carbonwallet to Execoin and much more!
