Parachains are the latest innovation in the blockchain, and it is one of the best improvements that the crypto industry has seen so far.

A guide to parachain in crypto

Parachains serve as an individual blockchain that runs within the Polkadot ecosystem, which allows parallelized transactions for scalability. These are the latest innovations that we have seen in the past few years when it comes to improving tech services in crypto.

The crypto industry has grown so much in recent years with tech experts looking for ways to further improve the system to provide a better user experience. The blockchain system, for example, has been continuously expanding to cater more users.

Parachains were created to ensure that blockchains will have a better system and address the problem with regards to scalability in the hopes to make a stable crypto ecosystem. These Polkadot parachains are secured with the use of the central chain known as the Relay Chain.

Both of these tap into the benefits of the ecosystem with the general cross-chain composability, which allows any type of asset or data to be moved from one parachain to another. This leads to a much bigger use for parachains as it can also be used to connect to other external networks through the use of cross-network bridges.

Parachain’s best characteristics


Parachains have a lot of benefits starting with its advanced characteristics. This is why a lot of people favour Polkadot’s innovations in the past few years. The extension of the blockchain was seen as a huge win in the development and growth of the crypto industry.

Here are the best characteristics of parachain:

  • Specialisation and flexibility
     

Perhaps the biggest technological advancement of parachain was the model itself. It was made to project the future of the internet and show how it would look like. For starters, the developers of the project saw the internet using a lot of blockchains that offer various services from one another but are connected as a single unit.

All of these chains can be used for different purposes, such as online gaming, finance, food and so on. With no criteria on the parachain design, this just means that it is flexible and can have its own unique design to begin with. The possibilities are endless and there is clearly more in store for the protocol.

  • Scalability
     

Scalability was the reason why the parachain was developed in the first place. The entire model of the parachain was to allow Polkadot to reach major scalability instead of having the need to rely on different solutions. This solution was a much more efficient way to help the blockchain serve its purpose well. 

Innovation on parachain meaning crypto tech has been growing so much in the past few years. Even though there are a lot of doubts on what are Polkadot parachains, it proves that it can pose scalability in the network.

  • Interoperability
     

Interoperability means that the blockchain has the permission to use parachains to have full control over their own chain. These parachains will also benefit from their ability to engage in free trade not just with other parachains but with external networks as well.

This is the main focus of the cross-chain composability that made it possible to send tokens and both off-chain and regular data such as verifiable credentials, smart contracts calls. This allows seamless transactions and less time needed to make transfers and so on.

  • Governance
     

Governance means that parachains can adopt any model to be used. This is also because there are a lot of pre-built modules that can be applied depending on the governance system needed. It is one of the best ways to provide a flexible access to the most sophisticated on-chain governance mechanisms.

It is also seen as a method to reduce the chance of hard forks on their chain. A flexible governance can be a good trait for parachains since hard forks were considered a problem that led to a split in many networks such as with Bitcoin Cash and Bitcoin SV in November 2018.

Parachain’s uses


How do parachains work, exactly? They have a lot more uses than most people think. Just as many other services provided on the internet, parachains crypto cover a wide array of applications such as the following:

  • DeFi
     

Decentralised finance or DeFi, is one of the most expected uses of parachains as it connects the use of reimaging the financial transaction based on blockchain tech. This means that there is a much bigger space allowed for DeFi with the help of parachains. That makes it easier for DeFi transactions to be completed at a much faster rate.

  • Smart contracts
     

Smart contracts are stored on the blockchain that runs on predetermined conditions. These are mostly used to automate the execution of a command to ensure that all participants will be certain of the outcome. These computer protocols benefit well from the parachains as this means that they can extend and execute more commands at a much faster rate than usual.

  • Data storage
     

The first two uses mostly benefit from extra storage and faster use. Data storage is on a much bigger win since parachains allow more usage. This is just the same as how a PC gets rammed up with upgrades on RAM and the graphics card.

  • Niche use
     

With their own runtime logic, parachains are a much more effective help for niche use since it can make it even better when it comes to the actual result. Niche use means engineering bigger results on making bigger focuses on various ideas.

Difference from parathreads


While parachains are the sole focus on helping extend the blockchain on a bigger scale, some projects also fail to secure a parachain slot but still end up running as parathreads. These are smaller parachains that can connect to Polkadot by using a pay as you go model. 

Projects may switch from being a parachain or parathread depending on their needs along with the availability of parachain slots on the Relay Chain. This is done by expanding on more blocks since the connection of parathreads is done on a block by block basis.

Parathreads are just temporary connections, while parachains work as an extension of the actual blockchain. This means that there is always a connection for blockchain reserved for how many parachains on Polkadot are set.

There is a long list of Polkadot parachains that are available for connection at all times. Parathreads, on the other hand, are limited and have select connections depending on the blockchain that the said parachain is connected with.

Why parachains are important in crypto


The parachain is just an extended part of the blockchain that utilises various types of consensus algorithms depending on use. Each of these chains have a lot of blocks that are connected by cryptographic hashes.

Parachains are important because they create smaller and more manageable chains that can be easier to use and maintain than the usual blocks. The crypto industry has already invested a lot in terms of how they can make crypto more relevant to the general public.

The blockchain remains superior in any way compared to other conventional systems. However, the lack of scaling ability has affected it from time to time and it is even seen as Bitcoin’s biggest flaw over the years.

That says a lot about the way parachains have been an important part of the crypto industry. The chain serves as a bigger way for the blockchain to be fully efficient. That’s what parachains crypto are made for.

Types of parachains


There are a lot of parachains that have different uses depending on the blockchain they are connected to. For instance, each parachain serves as a connection and extended reach of the blockchain for specific purposes.

Here are the different types of parachains:

  • Encrypted Consortium Chains


These are private chains that do not leak any information that they hold to the public. However, with an XCMP protocol at work, which is a message-passing protocol, the parachain can send messages to one another and guarantees about the accuracy of the information being sent.

  • High-Frequency Chains
     

These chains are made for faster transactions. High-frequency chains can compute a lot of information in a short span of time with the use of trade-offs and even optimisations. This is one of the most efficient types of parachains that is widely used among many blockchains nowadays.

  • Privacy Chains
     

Privacy chains are secure and encrypt every piece of information they receive through novel cryptography. This makes it the safest type of parachain and is mostly used for large transactions that require extra protection from hackers and such.

  • Smart Contract Chains
     

Smart contracts are more of a computer-like chain that has additional logic in them with the use of codes that allow them to decipher and process certain information that is not usual with other parachains. This makes smart contract chains unique and more desirable to use compared to other types.

The future with parachains


Parachains are clearly the biggest innovation that has been thriving well so far. This is why a lot of people continue to trust that crypto will be a more secure currency in the long run. With parachains now in place, it is safe to say that there is a bright future ahead for the crypto industry.

With parachains in place, this is just a glimpse of many greater things to come. That makes it easy to rely on crypto with more innovations that a lot of people would love to see.
