1st: NEO Smart IoT
By: hal0x2328, phetter
We saw two primary benefits to smart contracts when we first learned about them — the first is being able to accept micropayments with low or no fees, and second, being able to programmatically define when and how events should take place in the real world in a deterministic and verifiable way. Neo Smart IoT incorporates both of these ideas, drawing on our experience with inexpensive IoT devices like the NodeMCU to make it easy to simply accept a payment to do a “thing”, with no middleman taking a cut of the profits.
2nd: imusify
By: DavidWalters123, geek96, Nikolaj-K, metachris
imusify is a free, blockchain based, incentified and decentralized platform for music related digital content such as audio, video, apps, images, and blogging where anyone can join, contribute and get paid $IMU.
3rd: Chain Line
By: notatestuser
The project aims to solve problems of availability and price inconsistencies of products through creation of a global, trustless, peer-to-peer network of couriers coordinating with a smart contract.
4th: BlockAuth
By: revett
BlockAuth allows users to login (authenticate) to apps and websites by invoking a NEO smart contract from a NEO address tied to the user’s account. It aims to be the Blockchain OpenID.
5th: Phantasma
By: Relfos
Phantasma is a platform where the users control their own content, instead of relying in third parties servers. The platform support any kind of transactions between users, eg: email, chat, files, money transfers. NEO was used for this project due to its fast transactions and C# support, combined with IPFS (a distributed file system) to store the actual messages, encrypted with the keys from the NEO wallets.
6th: NeoTrade
By: birmas
Inspired by Etherdelta, NeoTrade is a NEO based smart contract that allows users to deposit NEO, GAS or any other NEP-5 asset directly to the smart contract and trade amongst themselves.
7th: Turing Complete Smart Contract
By: Nikolaj-K
This was the second programming language (a year after the lambda calculus, 1935) that was shown to be what is today called computationally universal and that’s a feature now found in most popular languages. The idea is to upload code routines to the intetnal storage in a way that they can be executed from within. The demonstrated concept enables, for the chosen modules of the smart contract, a re-programming even after a contract has been deployed to the blockchain.
8th: KRYPTON
By: MediaServe
KRYPTON is a decentralized version of Skype, where your wallet is your identity. With KRYPTON you can register your identity (public address) on any available provider and communicate with other identities. Communication includes voice calling, direct messaging and directly sending money. Just like Skype you can also make outbound voice calls (PSTN) if you have some credit. The difference here is that you can use any provider and the credit will stay in your wallet, under your control. This makes switching provider easier than ever.
9th: Switcheo
By: RavenXce, henrychua, jackyeu
Switcheo is a decentralised exchange built on NEO’s blockchain. It supports trading of NEP-5 tokens and NEO system assets like GAS & NEO. It aims to be a truly decentralised exchange while still providing for a superb user experience.
10th: TripShares
By: xtolya
This dApp is made for people which are confident in their travel plans. Drivers can make a higher deposit to be sure a trip will happen, passengers can search for higher deposit trips. So everyone will be happy in any case. With the smart contract as broker you don’t need a reliable middleman to hold deposit and solve disputes.
Honourable mentions
Smart Promise
By: SergeyAnkarenko, marlyonya
Smart Promise is an electronic journal of smart promises developed through Blockchain. User of such an environment receives a reward for each of his fulfilled promises. The concept of the idea contains the possibility to get a strong motivation to action that user pointed in promise.
Sunny dApp
By: JorritvandenBerg
The contract I created unlocks funds to a user on basis of input of an oracle. This can serve as an example for many use-cases in which a pay out depends on such input.
