DISCLAIMER: I am in no way associated with the NKN team. Neither am I a financial advisor, nor is this meant to be financial advice. Whatever follows, just reflects my understanding of the project, and my personal opinion on its future outlook.

This article describes the motivations, goals and workings of NKN.NKN aims to create decentralised internet by creating its own blockchain.

Motivations

Current day internet suffers from some of the below mentioned issues:

Privacy — Ability to protect PII(Personally Identifiable Information such as name, address etc) as well as user behaviour when visiting website.
Network Fragmentation — Idea that internet will be split into small segments and each segment will be disconnected from each other thus threatening the whole idea of world wide web.
Net Neutrality — Internet Service Providers (ISPs) should not block or throttle any data on internet based on location, content, application so on and so forth.
Insufficient Usage Of Network — Wasting your available bandwidth for data transfer.
Selective Propagation — Where only some data is allowed to be transmitted on the network, while the rest is censored.

Introducing NKN

NKN (New Kind of Network) is aimed at tackling all the above mentioned challenges and much more. It uses secure tunneling on top of tcp/ip stack to transmit data without altering the underlying mechanism on internet connectivity.

It is a blockchain in its own right but designed in such a way that it can replace networking stack of any existing blockchain as well. It uses cellular automata to achieve consensus.

Vision Of NKN

NKN tries to exploit the 3rd dimension of internet infrastructure i.e, network. As you can see, as of today we have seen innovations and blockchains based on compute and storage dimension.

Building blocks

Following are the building blocks of the NKN blockchain.

Building blocks

Networks Layer: NKN network layer overlays IP layer of OSI model and creates a secure/insecure tunnel between peers. Based on the rules of cellular automata, a dynamic topology of network is created to transmit data.

Consensus Layer: NKN uses cellular automata driven consensus called Proof Of Relay. This takes into consideration how your node bandwidth is and how connected you are for transmitting data.

Incentive Layer: You will be rewarded tokens as an incentive to be online and for providing connectivity and transmission power.

Application Layer: Contains the Distributed Applications (dApps) from application developer using the networking toolkit released by NKN, making applications very fast and scalable by making use of the networking layer.

Cellular Automata (CA)

CA is used as foundation for NKN. CA is a state machine where nodes have defined local rules which depends on only neighbouring nodes. They change their state only based on that. This will in turn affect the global network topology.

Check out the following video which shows evolution of the cells with predefined rules in conways game of life.

Applying the above principles to blockchain, Cellular Automata Of Network (CAoN) in a blockchain system where blocks are being generated.

Each time a block is received, the node updates its state and sends the block to the neighbours with digital signature. The neighbours will decide whetherto forward the message depending on their states.It can receive block in valid state or in conflicted state.Decision making process happens and it affects the the topology of the entire network without changing the physical layer or the underlying protocol of the network.

Consensus Mechanism

As you might be aware, there are various consensus algorithms being implemented in current day blockchains like PoW (Proof Of Work), PoS (Proof Of Stake), DPoS (Delegated Proof Of Stake), PoA (Proof Of Authority)so on and so forth which are briefly explained this nice article.

NKN, however, uses the ProofOfRelay(PoR) consensus mechanism that encourages participants that encourages participants to contribute to blockchain network by sharing their connectivity and bandwidth to get rewards, enhancing network connectivity and data transmission capacity. PoR is a useful Proof of Work (PoW) and it does not waste computing resources by making participants solve hashing computation.

Comparison to existing solution

Its outside the scope of this article to discuss and compare existing “similar” solutions but I am going to quote NKN team members on this.

People often ask us, what is different about NKN compared to BlockMesh and RightMesh. The latter two are entirely focusing on mobile phones and using Wi-Fi, Bluetooth, and Wi-Fi Direct. NKN intend to change the entire Internet, including fixed and mobile, phones, laptops, edge and core network. NKN is a protocol overlay that is independent of the underlying physical communication media, and transparent to applications.

In addition, BlockMesh and RightMesh are all based on Ethereum, ERC-20 tokens and smart contracts. NKN will have its own blockchain technology that will have fundamentally new Proof of Relay and new consensus algorithms that will be newly developed specifically for tokenizing the network transmission capabilities. Our core developers are going a bit extra nerdy here. And if you are technology details oriented, you are welcome to read up on Cellular Automata and Conway’s Game of Life. 🙂

The second difference also applies to Orchid Protocol, which is an evolved TOR with Ethereum. And NKN believe we have a much broader scope: we want to tokenize networking like what IPFS did to storage. Our target is the 1 trillion dollar communications business, and how we can provide better connectivity to everyone by incentivize the sharing of unused networking resources, expanding and upgrading the sharing network.

Roadmap
