Top 13 BEST Blockchain DNS Software [UPDATED LIST]

Learn all about Blockchain DNS Software along with the most popular Blockchain DNS along with their features in this in-depth guide:

DNS is now prone to distributed denial of service (DDoS) attacks where an attack to centralized Internet servers leads to the breaking down of websites.

For instance, a DDoS attack on a company like Dyn that controls much of the Internet’s infrastructure may lead to the breakdown of most websites.

The security of DNS is also threatened by man-in-the-middle attacks, and DNS cache poisoning, DNS spoofing, and DNS ID hacking, etc., all known as DNS protocol attacks.

Blockchain DNS Tutorial

Blockchain DNS

In a DDoS/DoS attack, the network is unable to respond to normal requests as it is maliciously flooded with a flood of requests to exceed the required load to the server. This is done when a network of computers is wrongly configured or invaded with malware to direct or redirect a lot of traffic to the server.

DNS queries can also be redirected to attackers by the attackers infecting a trusted DHCP server with malware such that the network uses a malicious resolver. This is because most devices will send the DNS requests to the resolver which can be arranged by network providers via DHCP protocol.

This is due to the fact that although traditional DNS servers are distributed all over the world, they are centralized in administration and redundancy as they refer to a central authority, a single point of failure.

For instance, ICANN, which is administered by the US, manages the root zone. DNS relies on unencrypted UDP packets, hence there is no end-to-end data integrity.

Fact Check:

  • 99.9% of all DNS servers, another DNS asset, and DNS providers are non-blockchain. Just about 0.1% is blockchain DNS assets and providers.
  • Blockchain DNS can help to improve the integrity of the information that it does not tamper with the availability of information, confidentiality, authentication of information, and non-repudiation of information to assure that one cannot deny action in a system. These are the most important things in an information system.

Pro-Tips:

  • Blockchain DNS can be used as a separate software or over the browser. The easiest and quickest way to use this DNS is via website browser extensions such as Blockchain DNS for Firefox, Frigate, or NEM Blockchain DNS extensions.
  • Some blockchain DNS services such as the Ethereum Name Service allows resolving of domain names via traditional DNS and blockchain DNS systems. These are more preferable to combine the benefits of both worlds.

What Is Blockchain DNS

A blockchain DNS is a decentralized DNS server that allows registering, managing, and resolving of domain names on the blockchain. Decentralized means that the network is run and related files are stored and shared on a peer-to-peer server system where network participants acting as nodes connect to each other directly without middlemen.

Generally, a domain name server is a public directory stored on a network of computer servers, and which receives inputs from the user using the internet and website for instance via a browser, to convert them into machine-readable formats. The process is known as DNS resolution.

For instance, the DNS service will convert a website address like www.softwaretestinghelp.com into a system of numbers called an IP address, which is readable and interpretable by machines than would the alphabetical letters.

This IP allows the browser the user is using to browse the internet, to find the right server on the Internet so the user will find the information they are looking for.

The website address is associated with the DNS with the corresponding IP. The DNS service associates Internet resources with particular IP addresses, thereby making them usable in different hosts, networks, protocols, Internet, and administration activity.

Centralized Vs Decentralized DNS Servers

How Blockchain Solves Problems in Current DNS Systems?

Traditionally, DNS’s are based on a centralized server i.e. servers controlled by select organizations and groups and people.

Organizations such as the Internet Corporation for Assigned Names approve Top Level Domains (TLDs) names like those with .com extension and accredits domain name registrars such as Godaddy to sell the rights to use domain names. Registrars also operate the TLDs.

The fact that only a few organizations control centralized DNS servers expose internet services to censorship or blockage says by those controlling the server resources or governments, as well by the way of disruption following natural disasters or unseen situations.

Centralized systems are also more vulnerable to cyber-attacks and corruption as the attackers would only need to hijack a few servers or corrupt a few controllers. They are also affected politically by domain theft and seizures.

Centralized DNS systems are not encrypted or have weak encryption, meaning the DNS Server and everyone else on the route i.e. governments, spies, hackers, etc know what website you are requesting to visit, etc.

Over-relying on a single corporation to oversee the DNS root and to assign top-level domains can lead to problems such as the corporations being under pressure from governments and organizations, such that they could be forced to remove some names from the DNS or prohibit the use of certain names.

Also, a government or authority could for instance direct that Internet Service Providers in a certain country stop directing domain traffic to a particular IP address, which constitutes censorship.

A centralized internet server is also prone to hacking. The digital certificate issuer organizations can be hacked leading to the issue of fake digital certificates and to compromise the security of web connections and expose websites and emails to hacking.

Centralization also means lack of service or downtime when one component of the whole is not working as the resources are hierarchical.

To solve the above problems – which may not be always a problem since harmful content for instance adult content reaching kids – may be successfully blocked for the better good, and decentralized DNS was invented.

In a blockchain DNS, the DNS is based on blockchain technology, which is based on a decentralized peer to peer network or peer-to-peer sharing of Internet resources.

As the DNS files and resources are first encrypted by cryptography and then shared and distributed across the entire blockchain network, they are harder to hack, modify, delete, or corrupt, or be interrupted by way of censorship by governments or by way of a natural disaster affecting a localized region.

That is if the network is really distributed say beyond the geographies where those limitations are occurring. Blockchain DNS also features blockchain website domain extensions that include .bit, .bazar, .coin among others. The lookup tables are shared across a distributed peer-to-peer network on the blockchain.

Workings Of A Blockchain DNS

  • In a blockchain DNS, the blockchain is used as secure storage and data or info management system. For instance, as information is encrypted and stored in blocks immutably, with timestamps, it is easier to audit and harder to tamper with and delete.
  • The distributed network of the server serving as blockchain domain name server resources are connected on a peer to peer basis via nodes. The nodes are equal in power with no authority over the other. All owners are required to contribute or delegate their votes to specific nodes to decide on matters and changes relating to the blockchain DNS.
  • As no single or a few organizations operate the centralized DNS servers, it is hard for powerful stakeholders and governments who always apply considerable pressure to influence the guidelines related to the use of DNS – to influence their use and the regulations.
  • Further, registrations contain unique encrypted hashes instead of individual names and addresses and thus it is hard to do an unfair takedown of a site.
  • Blockchain offers new flexibility and many opportunities. It does not result in many cost problems that arise with a centralized DNS system. Blockchain can also reduce costs as it eliminates wrangles, increases efficiencies, eliminates ambiguities that result in high costs, as well as introduces more flexibility of registries. For instance, complex interactions with domain registrars and oversees of the process such as ICANN introduces unnecessary costs. This can help to introduce more variable pricing and auction models.
  • Small operators can also launch Top Level Domain systems. For instance, for a given niche or purpose.
  • The blockchain-based DNS over HTTPS or DoH resolves DNS requests via an encrypted HTTPS protocol, that improves the privacy and security of communications. The HTTPS protocol is decrypted only at the DNS server where the DNS request is being processed to respond to the searches or requests by an Internet user and is sent back to the user in an encrypted version.

Owners of domain names store cryptographic signatures on a public blockchain. It means a device, app or other services using the internet will check a corresponding entry to find the correct signature. Thus there is no need to contact a central organization to get a digital certificate.

Blockchain Domains

These are websites based on the blockchain. Unlike traditional website domains, these are not popular, have non-ordinary extensions like .eth, are based on complex smart contracts to form a human-readable web address, and a user will need to install special extensions and plugins on their normal website browser to access these types of websites.

Domain owners will register a domain on a blockchain. These owners, just like with crypto coins, will get private keys (crypto wallets) to the domain and can control the domain fully. Users can launch their websites without contacting or getting permission from ICANN.

Just like crypto coins, the web domain assets belong to the domain owner and not a central authority. The domains cannot be censored. Users can choose whichever extensions they want or need.

These domains can make payments on the Internet native in addition to being secure and seamless – the users can send payments to domain names directly instead of using alphanumeric addresses or a long numeric account number.

Providers of blockchain domains include Alibaba, Aloaha blockchain DNS, Handshake, and Luxe, Ethereum, NEM, etc.

Qualities Of A Blockchain DNS/How Blockchain Would Help DNS

#1) Availability means no service disruptions on the hosted websites. Peer-to-peer network hosting of websites ensures availability on a 24-hour basis.

#2) Integrity ensures no corruption of data on the DNS. Blockchain achieves consensus using consensus protocol and this ensures integrity, meaning there is no need for DNSSEC’s famous key renewal. Blockchain ensures cryptography encryption, so data cannot easily be hacked and corrupted or modified.

#3) Confidentiality ensures the protection of the privacy of the users by implementing a variety of solutions and methods. Just as in DNS over HTTPS (DoH) protocol works to ensure confidentiality, requests to the blockchain can be encapsulated in an HTTPS (DoH) protocol.

DoH resolvers can also be deployed on blockchain for the purposes of decentralization.

DNS on the blockchain ensures that all the DNS data – DNS zone files or domain name configurations – as well as all the players (domain registries, registrars, etc), are registered on a distributed blockchain network to facilitate better management of the DNS in a more secure manner.

Types Of Blockchain DNS

Blockchain DNS can be used as a browser extension or stand-alone software. As a browser extension, all you need to use the DNS is open a browser and search on the extension page for the particular extension and install it. Then you will be able to tweak a few settings relating to the use of the software.
