What are Parachains? A Comprehensive Guide To Polkadot and Kusama Parachains

The new decade is a time of opportunity, and cryptocurrencies are unlocking an era of decentralized finance in which connectivity and privacy can work together to create unprecedented results. Every day opens up new possibilities for innovation and expansion in the sector, which lays the groundwork for exciting product launches. As a Blockchain Platform, firms can bring powerful updates to the system that are in line with user needs. Parachains were born out of the constant desire to improve the existing.

Learn blockchain technology to be an industry prospect are well aware of its perks as well as its limitations. Among the many lucrative benefits lies the shockingly large number of disadvantages that limit the potential of the cryptocurrency industry. This is a major concern as it raises questions about the usability of blockchain technology.

Parachains were created to solve the scaling issue. They are a support system to the diverse ecosystem of Polkadot and Kusama blockchains. In August 2020, Polkadot was launched as an alternative to the Ethereum network. Popularity was gained by the Proof of-Stake consensus algorithm, which was more efficient than Ethereum’s proof/of-work module. Polkadot’s global expansion was fueled by the inclusion of Parachains. Kusama is Polkadot’s sister chain, and it is devoted to innovation and early-stage deployments. Kusama is a well-known canary network that facilitates testing by supporting the publication of unaudited codes before they are available on the main network.

Let’s explore Parachains more and learn about the blockchain technology module for parachains in Polkadot networks and Kusama.

What’s Polkadot Parachain and

Parachains, which are heterogeneous Blockchains that run parallel with layer 0, also known as the Relay Chain of the Polkadot or Kusama ecosystems, are heterogeneous. Pachains, named after the word “parallel”, are Layer 1 infrastructures that provide a transaction trail to the main chain and help boost Polkadot’s core scalability.

Parachains are unique because they have project-specific data structures that can be used in the Polkadot or Kusama multichain environments. Parachains can be implemented in a variety of ways, including private or public, as well as being linked with tokens, native features, and other critical elements. Parachains can be considered independent systems that integrate seamlessly with the Polkadot ecosystem, allowing for swift cross-chain interaction. Parachains allow for faster and more cost-efficient transactions, in addition to interoperability. Developers can create their projects using customizable tools. They can also use tokens and have exclusive use cases. Parachains’ infrastructure is user-friendly, which has led to a rise in adoption of Polkadot & Kusama.

Parachains, which are independent blockchains that are integrated to the main Relay Chain and protected by it, have their own governance structures and tokens. As long as the parachains remain connected to the main chain, the Polkadot or Kusama ecosystems can support many elements such security, interoperability and governance. Because they can use the existing infrastructure of Polkadot for security purposes, projects are encouraged to infuse Polkadot. They no longer need to have their own validator nos. They can easily share the validator nosdes of the mainchain. The central chain coordinates all aspects of the system and manages them.

Polkadot’s cross-chain functionality allows for quick movement and exchanging of assets and information among parachains. This process opens up new uses and applications for the blockchain channel. Cross-network bridges allow parachains to interact with other networks such as Bitcoin and Ethereum. Developers can use blockchain technology training to be able to easily work across all Polkadot-related chains.

How do Parachains connect to the Mainchain?

Parachains are a part of the central Relay Chain of Polkadot and provide additional support for the core infrastructure. The Relay Chain acts as a link between Parachains and the main chain. It is also responsible for primary features shared by all Parachains, so it is recognized as the focal support for the Polkadot or Kusama networks.

The Relay Chain is not the only important component. Substrate is also an important part of this equation. Substrate is the main blockchain SDK used by developers to create the parachains that make up Polkadot. This solution is also known as Web3 or the groundbreaking tool for web application development systems. Both Polkadot as well as Kusama utilize Substrate’s Web3 feature.

Parachain slots are required for inclusion in the Polkadot or Kusama networks. It is difficult to get a slot as there are very few available and a lot of competition. The permissionless candle auction sells the slots. This ensures that the safety and security of the blockchain channel.

How do Parachains Work?

DApp developers will not need to work within pre-determined budgets for Ethereum. Surprisingly this is not true with Polkadot or Kusama, which allow developers to set their own limits. These networks allow creators to create their own parachains, which they can tailor to their needs. Each parachain can have its own unique characteristics such as block time and mining rewards. Collier nodes manage parachains and keep track of their history. They also support the aggregation or blocks of transaction data for easy addition to Relay Chain.

Parachain Characteristics

Enhanced Interoperability

Parachains, tools that facilitate interoperability and are dedicated to the future development of blockchain technology, were created to help. This feature allows multiple layer 1 infrastructures to collaborate regardless of their specializations, objectives, or internal structures. Polkadot only supports one criteria for creating a parachain, so each block follows the agreed protocol.

Cross-chain Interactions

The ecosystem’s parachains Kusama, Polkadot can access and view data from all points of the network. They can also interact with each other and external channels. Parachains can exchange tokens and data easily due to cross-chain compatibility. This allows for the transfer of smart contract and off-chain data from Oracles.


Industry participants have always debated the issue of low scaleability. Scalability is the ability of a network to execute transactions within a specified time period. It is determined by block size and frequency. Parachains allow parallel processing of transactions within a decentralized module. Each parachain processes and distributes transactions side-by-side, increasing throughput.

Governance System

Users can guarantee accountability, transparency, democracy, and accountability within the ecosystem by having a strong governance structure. Polkadot parachains, unlike Kusama are free to choose any governance structure. This decreases the likelihood of hard forks. Parachains that do not want to create their own governance models can use the one already created by Polkadot. Trusted blockchain technology courses teach the importance of community participation in governance systems. This creates a sense that the user is responsible for their company.

What is Polkadot, Kusama Parachain and Slot Auctions?

Parachains must connect to the Relay Chain in order to be able to access Polkadot’s ecosystem. It is not difficult to choose the best projects. It is difficult to know who to connect with and when. Parachain slot auctions simplify the process of Blockchain Development on Polkadot.

Kusama, Parachain’s canary network manages parachain auctions before parachains can connect with the Relay Chain. These auctions allow for testing and optimization of projects. Parachains who are able to find a spot on Kusama, and work quickly, will likely be able to join Polkadot. Auctions are designed to give slots to projects who are interested in working on Polkadot and Kusama. You can have up to 100 parachains running simultaneously on the portal.

In an effort to improve the efficiency of auctions Polkadot switched to a revamped version of the candle auction format. It is open to everyone and anyone can participate. A project must create, build, optimize, and test a Parachain via Substrate in order to be eligible to participate in the auction. Polkadot certification programs provide detailed knowledge about parachain interoperability and auctions.

The project develops a strategy after construction and then joins the parachain to bid for the slots. Open bidding modules allow projects to see other bids and re-bid. The auction’s closing moment can be determined by the verifiable random functions or VRF. The auction pact is won by the highest number of DOT or KSM tokens accepting getting locked. When the lease ends, the tokens will be unlocked.

What is Parathreads?

Parathreads have a similar developmental structure to parachains, but are dissimilar on the economic clutch. They are connected to the Polkadot ecosystem through a pay-as you-go system, and each block is auctioned. Parathread is a great feature for projects who want to work on a temporary basis with Polkadot, but not permanently. Parathread is also useful for projects who fail to secure a full auction slot. Parachains are slower in terms of block time. They have the same level of interoperability and security as parachains. Depending on their needs and availability of slots, users can switch between parathread and parachain.

Polkadot’s Precedence in Market

In the past year, Polkadot saw a substantial rise in popularity and market share. This surge continued in the first quarter 2022, making Polkadot the most powerful player in crypto. 13 parachains won a slot in an auction at 127.8M DOT, which is 11% of total supply.

It has also scheduled 28 additional parachain slots until February 2023, indicating its widespread expansion within the sector. At the first parachain slot auction, both the token price and number of users reached new highs. The Polkadot ecosystem has seen the most developer activity. The company now plans to implement the Cross-Consensus Message Format, parthreads and performance upgrades. Polkadot certifications are a way for investors to learn more about the Polkadot Blockchain Platform’s working module.

Final Thoughts

Parachain, a project-centric Blockchain network, aims to improve the efficiency of Polkadot. Parachains will allow Polkadot to assist users working within its cluster by improving security, scalability and interoperability. The parachain auction is a key part of Polkadot’s training program. It allows projects to connect to the main chains by easily grabbing a slot. Many projects are having difficulty getting a Polkadot parachain slot. The future looks bright for Polakdot’s growth and development.
