No,  Sling's market is a blockchain, not a messaging system.  

Shadowcoin's messaging system uses an ECC key for encryption (secp256k1) with a known trap door and is  labelled "unsafe" on this site  http://safecurves.cr.yp.to  

Sling also uses secp256k1 for messaging but that will change soon.  I am think of changing it to use Curve383187.

The crypto signing aspects of secp256k1 does not have a trapdoor so all these transaction blockchains are still "safe".  

Ik denk dat het maar beter is als jij gewoon zelf jouw bek houd, je hebt 0 bewijs voor jouw komplot theorieen. En btw, als jij een punt wilt maken dan lijkt mij het beter als jij dat met jouw echte account doet. Met de naam fakeSDC dev maak je niet zo'n goede indruk Overigens heeft SDC nog geen succesvolle peer to peer markt kunnen opzetten.

They have not released the new Shadowcoin wallet code yet, but find nothing wrong with porting their code. Since they are using the MIT license, it is perfectly legal/okay/acceptable to use their code in any way.  Most alt-coins are > 80% bitcoin code with pieces of other alts.  I think this is great for the evolution of crypto software.

Unlike Sling, Shadowcoin has not released a working decentralized market yet.  Maybe they copied the Sling code to implement their marketplace.

New ShadowCore Client Now Available For Public Testing


Our development team has been hard at work integrating new features into ShadowCore that will better support our upcoming ShadowMarket. In order to best support a P2P marketplace environment the ShadowCore client has been updated to prepare the network to switch from using Proof of Stake to Proof of Stake v2. PoS v2’s revised coin weight calculation encourages greater network stability by not factoring in “coin age”. Therefore saving up coin age is no longer possible so nodes will need to be online more in order to get their stake reward. It'll involve a move from scrypt to SHA256 which will mean staking requires less processing power (especially helpful for mobile users wishing to stake their coins). The new system is also designed to solve security issues which made PoS v1 coins open to certain theoretical attacks. For more information see Blackcoin's Proof-of-Stake Protocol v2 white paper.                 
         
The upgrade took a great deal of work from the developers (you can view full details of the 230 changed files with 12,219 additions and 8,455 deletions here. There’s a summary of the changes in the release notes.

ShadowGo Progress Update


We’re currently putting the finishing touches to an upgraded version of our Android wallet. This will give mobile users the full anonymizing functionality of ShadowSend v2. The beta version will be posted in the next few days for a short round of community testing before the full release. Stay tuned for further details.


ShadowMarket Progress Update


Good progress is being made on the Shadow Marketplace. Our developers expect to pick up speed now that all the necessary updates have been made to ShadowCore and a date has been scheduled for the PoS v2 hard fork. We will be working on upgrading ShadowChat for secure messaging, which will be the backbone of the whole market place, using BIP32 addresses for category trees. After that we will be working on anonymous mutltisig transactions. We are aiming to have a beta version ready for public testing and feedback within Q2. ShadowMarket will be the primary focus of our developers and the next feature to be added to the ShadowCore client.


Thank you all for your continued support and enthusiasm,

Hey all

The testing is going well.
There have been a few cosmetic issues that have been spotted.
We are working on these
