NKN – Gitcoin GR11 Hackathon Winner Showcase #2


In this mini series, we will feature several dApps that won the recent NKN – Gitcoin GR11 hackathon. Some of these tools might be quite useful for your daily work and life, so please do give them a try. In addition, we will also try to introduce the developers behind these winning dApps about their experience developing web 3.0 decentralized applications.


Right after we opened our series with Riddle last week, we are happy to present you another fascinating dApp nRide developed by Martin Arrivets. It is an open, free and decentralized Uber-like ridesharing Service fully powered by our NKN network. 

Unlike other ride-hailing service applications, nRide implements a p2p protocol over NKN’s unique network to connect riders and drivers directly.  This ensures there is no big company in the middle charging a hefty  platform fee. 

See nRide’s demo Video here:

Now, let’s have a virtual chat with nRide’s developer Martin Arrivets to explore a little bit more about his thoughts developing this dApp.

A chat with Martin, nRide’s developer

1) Hi Martin, happy to e-meet you. Can you first introduce yourself?

Hi, nice to meet you. I am a software developer with a focus on blockchain and distributed systems. For the past few years, I have been contributing open-source software for what is referred to as web 3.0.. In particular I created Babble, a lightweight and efficient consensus algorithm intended for mobile devices. One of the main difficulties in creating truly p2p mobile applications is the networking layer; how do you establish direct communication between mobile devices without relying on centralized servers? Given all the hurdles of traditional networks, I strongly believe that NKN’s incentivized overlay network is the right solution to this problem, and I plan on using it in my projects. 

2) Congratulations on winning the NKN GR11 hackathon bounty! Can you explain a bit about nRide, what it does, and what are its unique benefits?

nRide aims to be an Uber-like service where drivers and passengers interact directly with one-another without relying on a central third party. The main advantage of such a system is that it would eliminate the platform fee that drivers usually pay to providers like Uber or Lyft, which is around 20% on each fare. NKN plays a crucial role in making this possible as it provides the networking layer that enables passengers and drivers to discover each other and communicate directly through encrypted tunnels without relying on centralized infrastructure. Additionally nRide users have a possibility to invest in the very platform that supports the app by acquiring NKN tokens or running NKN nodes. This is an improvement over the current status-quo where everything is controlled and owned by centralised companies.

3) I heard developing decentralized apps (dApp) is quite hard, compared to the traditional client/server model in Web 2.0. Can you talk a bit about the challenges you met while developing nRide, and how you overcame them?

I actually think developing dApps is somewhat easier than traditional Web 2.0 apps because you don’t have to write and maintain two codebases, one for the client side and one for the server side. Web 2.0 already has services like Firebase that save developers from having to write their own server code. I think blockchains like NKN play a similar role, with the benefit that they are decentralized and participative by nature. With nRide I basically needed a mechanism for users to discover one-another and exchange messages directly. NKN offers a perfect solution with a pub-sub mechanism, 1-to-many and 1-to-1 messaging.

4) Is there anything in the NKN SDK and documentation that needs improvement to make it more friendly to developers like you?

For nRide I used the NKN Flutter SDK which was amazing. I found it very easy and straightforward to use. It was actually much more challenging to figure out how to use Google’s SDKs for Maps, location, etc, which the app also relies on. 

5) What are your future plans for nRide and dApp development in general? 

At this stage nRide is just a very crude proof of concept, so I would love to improve on it until it can be tested in the open. It would be amazing to get other people interested in the project, like developers, designers, writers, and users of course. I am very enthusiastic that we are getting very close to seeing real Web3 apps out there, and I think this will be the next big wave of investments in blockchain.
