Forums, messengers, voting, gaming, and more.

Last week, 65+ community developers have been applying final touches to their nOS dApps. We had the privilege to talk to every developer, provide feedback, award pre-sale tiers. And now, it’s time to present our Top 15 nOS Community dApps in this Medium post.

We’re very impressed by our developer community and by what they have achieved in this short amount of time. We’re also proud to say they helped nOS in the following achievement:

4 months ago nOS was announced at the NEO Amsterdam event. Now, nOS is the world’s first platform with 65+ dApps running on its public testnet before releasing a whitepaper and before holding its ICO.

Interested in development? All dApps are open source, so there are more than enough starting points for anyone to start building their own!

Presenting the Top 15 nOSNet Community dApps (in no particular order):

From NEO News Today:

Initially, Asif contributed to the nOS community by reporting a number of issues on its GitHub page pertaining to the nOS Client, and received “great and quick [responses] from this nOS team.” Furthermore, he said the “nOS client is [a] wonderful solution which makes life easier for developers,” which he believes will help nOS to become a “great blockchain service in [the] future.”

Bet Manager

nos://bet-manager.neo
Source code: https://github.com/MarcoBz/Frontend-Bet_Manager

Bet Manager is a decentralized betting application. Users can create groups and hold betting sessions for any topic. The winner is selected by majority vote during the “Validation Period”, which takes place after the betting period. The result that reached the majority amount of validations during the Validation period is the winning result.

Bet Manager has an in-depth explanation of its features and the betting process in its GitHub repository.

Notes by developer (marcobz#4117 on Discord):

A Group with all possible participants at future bets needs to be created in the dApp inserting the name of the group and the NEO address of all of them.
When a bet is proposed, it has to be created in the dApp inserting its text, at least two possible results, the amount of tokens that has to be bet, the blocks length of all the periods in the bet’s lifetime (they are described later) and it has to be checked or not if a player can add a new result.
Each person in the group can participate to the bet choosing one of the possible results and sending to the smartcontract the previously amount of tokens.
When the bet event ends, the result can be validated by all the participants in the group and if one result reaches 50 % + 1 of group participants, it is the winning result and winners can withdraw all the amount previously bet.
