Despite all this smart contract stuff, few of these "ICO coins" give the holders any authority over anything. It's not like 51% of the coin holders can fire management.
Ethereum now has half the market cap of Bitcoin, despite the total failure of the DAO, the one big application of the smart contract technology. See "Use Cases Of Ethereum In Different Sectors 2016".[1] It's been six months; what's actually working?
* Branche.io - payday loans. Got as far as the initial token offering 6 months ago. Then, nothing. Did they take the money and run?
* Iconomi.net - "digital asset management platform" - site says "Coming in 2017".
* Augur.net - prediction/gambling platform. Not yet operating for real, but there's a play-money beta.
* RexMLS.com - distributed real estate listing service. Was supposed to have test listings live in April 2017. Didn't happen.
* truststamp.net - distributed identity system to detect fake social accounts. "Connect your Social Networks. The more accounts you connect, the higher your potential Trust Score! Your account information is not stored and your privacy is protected." Not working yet. If it did work, spammers could defeat it by creating interlinked fake accounts on Twitter, Facebook, etc., which some already do.
* chainy.info - store misc. info such as URL shortening bindings on the Etherium blockchain. This seems to work, but isn't used much. If it caught on like tinyurl, the Ethereum blockchain would choke on the traffic.
* uport.me - "self sovereign identity". Still at "sign up for alpha".
* dynamisapp.com - supplementary unemployment insurance that checks LinkedIn to see if you're employed. Not working. Last blog update January 2016.
* ico.inchain.io - insurance against cyber hacks. Site not responding.
* ujomusic.com - some kind of music platform. Not working yet.
* peertracks.com - distributed music royalty system. Not working yet.
* singulardtv.com - distributed video payment system. 5000 Twitter followers! Not working yet.
* beyond-the-void.net - game with Ethereum contracts for in-game currency. Beta version downloadable. At least it's running.
* firstblood.io - e-sports where you can put up money on your play. Alpha available, no beta yet.
* etherplay.io - "Play games and win tokens" - "Coming Soon".
* akasha.world - distributed social network. There's a downloadable alpha.
* vdice.io - online gambling. Like Satoshi Dice, but for Etherium. "Coming soon".
* slock.it - the guys with the DAO and the IoT door lock. That didn't end well.
* electricchain.org - buy and sell solar power over the Ethereum block chain. Lots of PR. May actually be working on a tiny scale.
* lo3energy.com - another energy trading system. Lots of PR, no operating installations.
So that's what people are actually doing with Ethereum. Not all that much. Even the online gambling startups aren't fully operational.
