Information Centric Self-organizing Data Network; Interview with Mark Nezvisky, CMO of NDN LINK.

Data Network

NDN LINK’s information centric self-organizing data network is connecting businesses with blockchain powered data retrieval, centralized data, resources wasting management and content distribution.  The CMO of NDN LINK , Mark Nezvisky shares more details with us in an exlusive interview with TechBullion.

Please tell us more about yourself? 

My name is Mark Nezvisky, I’m the CMO of NDN Link. I met with the founder of NDN Link earlier this year and was impressed by the idea behind this great piece of technology. 

I instantly wanted to become a part of this revolutionary journey. My mission at NDN Link is to explain to people what NDN Link is in simple terms, so that anyone who’s interested in it may see the benefit.

What does NDN LINK do as a business and what is NDN Dataset Synchronization (NDN Sync)?

NDN Link is a combination of a Named Data Networking Protocol and Blockchain. Named Data Networking allows us to fetch information on the Internet by NAME instead of the IP address like it is done now. 

This introduces us to a brand new experience for data transmission, storage and communication.

NDN Link is a public chain under an infrastructure which is similar to Ethereum. It is a distributed communication network driven by blockchain technology. It is a new generation of an Internet communication infrastructure and provides data transmission services anywhere in the world as well as safe and effective network transmission services for Dapps.

The NDN Link ecosystem  carries various ecological applications to provide data transmission services for developers and users.

NDN Synch is a multi-parties data communication protocol of NDN, which is different from the point-to-point communication protocol such as TCP/IP. NDN uses the NDN Sync communication protocol to support multi-parties communication, that is, multicast. 

Could you give us an overview of the Named Data Networking market and some use cases?

For example, with NDN Link you could have a live streaming service broadcasting videos to millions of users in 4k quality without interruptions. Or a financial institution could store assets of their Clients on their services along with sensitive information without the fear of hacks of the server. The first one is possible because in NDN Link there are no central server dependencies, in other words, the broadcasted video is cached on the routers and devices of the network for future reuse by other viewers. This is possible because the data is not tied to the IP address of the server but only to name. So when a viewer wants to watch that live stream content, that content will be fetched by name instead of IP. And the more users are joining the more content will be cached on the devices and routers within their proximity for future retrieval. The second scenario is possible because in the NDN Link network we are focused on data safety as much as we are focused on server or device safety. In the current IP design everyone is focused on how to protect the data by protecting the server or the device they are accessing the data from, but at NDN link we are also concerned about what would happen with the data in case the server or the device gets compromised. And because of our concern and multiple hacks on the Internet we are addressing this issue through cryptographic signature for every data packet that is uploaded unto the Internet. This way even if the server is hacked the data can only be accessed by the party that holds the keys.

What are the major features and services that make NDN LINK unique?

We are fetching data on the Internet by name instead of the IP address this gives the possibility to shift the network from a server-centric paradigm to a data-centric one.

We apply cryptography to each data packet created on the Internet which secures the data traveling across the network and not only focusing on the safety of the endpoints and channels of communication.

We store data on routers and devices of the network and not only on central servers. This gives the network more scalability and speed because the data is always nearby no matter where you are; it doesn’t have to be fetched across the globe.

Tell us more about your data retrieval services, how does it work?

A consumer expresses an interest (interest packet) in a particular piece of data(data packet). By default, in the NDN design that data has a unique name on the network. NDN Link checks if that data is stored near the consumer (their router or device nearby on the network) if not then it checks the Pending Interest Table to see where that data packet resides. After identifying the destination of the packet it uses the best forwarding strategy to retrieve it and bring it to the consumer. Multiple versions of the same data may be stored on various devices for ease of retrieval, only the party that expressed the interest and has the necessary cryptographic keys may be able to retrieve that data. When the data is retrieved it will travel back by the same path the request(interest packet) came through, thus decreasing the load on the network. After the Interest of the consumer was satisfied the record from the Pending Interest table is cleared. Similar interests are aggregated in order not to clog up the Pending Interest Table. Another possible scenario is if the data packet is not on the routers and there is no record in the Pending Interest Table, in that case NDN Link goes to the Forwarding Information Base and again uses the best forwarding strategy to decide on which server the data resides in order to bring it to the consumer. After the data was delivered it will be cached on the routers of the data network for the simplicity of future retrieval.

How does NDN LINK enable content distribution?

NDN Link has two types of parties on the network: the Content Producer and the Consumer. The content producer creates content and the NDN Link network applies a cryptographic signature on it with various information about the content; for example, its name, version, freshness, cryptographic key, etc. Whenever there’s an Interest from the consumer that matches the name and other information of the content then NDN Link delivers the the corresponding data packet(content) to the (consumer). 

The records of these transactions are stored in the Pending Interest Table that we’ve mentioned before and after the delivery of the content it’s cached on the network for future reuse.

Tell us about your legal and data security measures at NDN LINK?

From a legal standpoint we abide by all the international laws and regulations that protect the parties of online communications. For example, we don’t own or store any data of our content producers or consumers, all the data belongs to the person that has the keys to it. We don’t resell data or involve any third-parties in the communication process between our content producers and consumers. The fact that the data belongs to the end consumer or content producer is also inline with the GDPR regulations.

All of our data security measures are built around protecting the data with the help of cryptographic signatures that I’ve described before as well as with the help of blockchain technology that we utilize together with the NDN Protocol.
