Know Parachain as an intermediate chain that is connected to the relay chain layer-0 of Polkadot. This relay chain sits located at the center, while the Parachains run in parallel with the relay chain. It is the Parachain that will be managed by the collator. Collators function as a full node in the Parachain. They are responsible for the preservation of all the necessary information about the Parachain. They also generate new block candidates and transmit the information to Relay Chain validators for verification and integration into the common state Polkadot.
Parachains could possess their own economies and tokens. They could also possess their own rules regarding implementation, for instance, they could define whether collator nodes need to put their DOTs into the relay chain. Additionally, they could determine the incentive for the collator nodes. The collator nodes receive a reward by the inflation of the native Parachain token. There are however different ways to reward.
There’s so much excitement about Parachains due to the fact that, in their design, they have the Polkadot’s cross-chain composability and interoperability. This means that they are able to send and receive any kind of asset or data with other Parachains. Thus, Parachains can be used to support an array of innovative applications and uses. Additionally, they benefit and share their security and scalability, and administration of Polkadot. Let’s look at the major advantages of Parachains.
What are the advantages of Parachains?
Flexibility
In the design of Parachains Polkadot offers the most flexibility. The only requirement set by Polkadot is that the Parachain must demonstrate to Polkadot Validators that each block follows the protocol agreed upon. This means that the Parachain has to adhere to the agreement that the relay chain has reached. Due to this flexibility, it is possible for a Parachain could be designed as a chain that has its own unique design. It is able to be operated in both private and public networks and can even have its own token and governance system. It could also be used as a platform that allows other developers to develop applications that are built on it.
Scalability
Interoperability, which is the capacity to work with different blockchains one of the most important factors that determine the capacity of any blockchain. Although other blockchains must rely on layer-2 interoperability solutions Parachains Parachain is able to achieve interoperability at the layer1 level itself. So, Parachains are an efficient and decentralized way to increase the speed and scalability of blockchains because their transactions are able to be spread and processed in parallel across an entire ecosystem of layer-1 blockchains.
Interoperability
One of the major benefits of Parachains is that Parachain can be that it automatically gains Polkadot’s cross-chain composability. This means that a Parachain as an intermediate blockchain will provide total control and control over blockchain communities as well as enable them to engage in free trade with other Parachains as well as external networks. By leveraging Polkadot Interoperability Parachains are able to exchange tokens and not only tokens but also all kinds of information, such as authentic credentials, off-chain information from oracles, and smart contracts. So, a parachain cannot operate in silos and can be reopened for new options.
Governance
As we mentioned previously, Parachains are free to adopt any governance system. They can also incorporate a variety of built-in modules for the implementation of various governance systems on-chain. The ability to access sophisticated on-chain governance tools minimizes the chance of hard forks in the Parachain. In addition, on-chain governance gives Parachain communities accountable transparency. Parachain communities with accountability and transparency.
What exactly is Parachain consensus?
As we have discussed, Parachain can have a large amount of flexibility in its structure as well as its model, governance, and token. However, in terms of its consensus mechanisms, Parachain should adhere to its own Polkadot Relay Chain. It isn’t allowed to allow Parachains to use different consensus algorithms. It is a reason why that a Parachain can’t perform a block’s finality outside the trust level that Polkadot gives, however they decide who and how can write the blocks. But the sovereign chains that connect with each other via the Relay Chain via a Parachain may be able to establish their own agreement.
What else can Parachains be employed to do?
The idea behind the Polkadot network that incorporates Parachains being layer one blockchains is about expanding the possible applications of Parachain by enabling connectivity, flexibility in design, and scaling. A few of the businesses and industries which have expressed an interest in running projects using Parachains include:
- Digital Wallets
- Decentralized Finance (DeFi)
- Smart Contracts
- Gaming
- Credentials
- Identity Verification
- Internet of Things
- Oracles (Price Feeds)
How can I run a Parachain using Polkadot?
Anyone who is interested in creating an application based on Parachains first needs to run a Parachain with Polkadot. The first need is to lease one of the slots for the Relay Chain. Slots to lease are available via the Parachain auction of slots, in which interested parties must make bids on the slots using the native Polkadot token DOT. The lease out Parachain slot in Polkadot is offered to the relevant team for a minimum period of six months, and up to a maximum of two years.
In order to take part in the Parachain slots auction, bidders have to secure the DOT amount they purchased to the length of their lease. After the lease has ended, the whole amount of DOT is unlocked. But during the lease the DOT amount remains in the account of the bidder, it is not able to be utilized for staking, transfer, or any other purposes.
There are many ways that interested parties can finance their bids. They can either self-fund or apply for crowd loans, in which holders of DOT contribute to be rewarded with a prize.
What are the costs and fees of operating the Parachain?
- To operate the Parachain on Polkadot It is essential to rent a slot what is the cost? In the ideal scenario, it is free as the entire number of DOT locks to the Parachain slot is released at the expiration of the lease. This also means that the Parachain is able to access all the computing power it requires, without incurring extra costs or “gas” expenses. But since the DOT remains in a locked state throughout the lease term and can’t be used for anything and therefore the cost of operating the Parachain is best described as an opportunity cost.
- A further cost that is associated with renting out slots involves the expense of remuneration for participants in the instances in which the money for slot leasing has been sourced through crowd loans.
- Collier nodes running on an individual Parachain can incur costs that is not too significant.
