Call me a Syscoin advocate, but wasn't Syscoin's Blockmarket the world's first decentralized marketplace?
Or is Bitbay currently open for public use?
Don't forget Nxt Marketplace (aka Digital Goods Store) in the Nxt core and the Freemarket add-on.
http://wiki.nxtcrypto.org/wiki/Marketplacehttp://nxtfreemarket.com/Each of these projects (BitBay, Syscoin, Nxt, and other blockchain based market places) should know about each other. Competition is good and hopefully will result in a better over-all user experience in the long run.
I agree, to be honest, im so busy its hard to look into all the other coins projects. But i wish them well and hope they all succeed. I dont see it as competition at all. Personally, if someone else takes double deposit escrow and makes it used worldwide because they got inspired then i would consider that a huge success.
As for Nxt markets, i know you have to jump through a few hoops to get everything set up. Also, they dont have multisignature nor do they have unbreakable double deposit contracts. So they would still need a good platform that doesnt rely on arbitration. Hopefully soon, i wont be so overworked and can look at what everyone else is working on.
