Polkadot Parachain Leads to Cross-Consensus Communication

All tokens such as Ethereum, Solana and Polkadot operate their own chains with the common goal of providing a scalable platform for distributed global apps. I am. Specifically, Polkadot allows you to use parachain, a custom project-specific blockchain that integrates with the Polkadot ecosystem.


The parachain is considered a parallel chain with its own runtime logic. It also benefits from the shared security and cross-chain messaging provided by the Polkadot relaychain.


The Parachain allows for great flexibility and customization, but requires more effort to create and maintain over time.


In the last two years, most crypto startups within the Polkadot ecosystem have wanted to eventually become a full-fledged parachain. But with the advent of integrated apps and DApps like RMRK and Zenlink, the question for startups today is whether they need to be parachained.


The advent of these embedded DApps and protocols indicates that the next phase of Polkadot could be the phase where parachains become an option throughout the ecosystem.


I think the integrated application will lead to best practices for cross-consensus communication formats and create a powerful and prosperous ecosystem that cannot be reproduced on other public chains.

Polkadot defines the difference between smart contracts and parachains as follows:


When implementing a function using a smart contract, the smart contract you create must be deployed in a particular chain and linked to the address in that chain. In contrast, a runtime or module developed on a parachain to implement the feature you want is to create a standalone state machine.


Smart contracts must be updated manually, while parachains will be able to swap out their code completely with root commands or governance pallets automatically, making upgrades easier.


When you build a smart contract, it will eventually be deployed to a target chain within a specific environment. Parachains allow developers to state their own chain`s environment and even allow others to write smart contracts for them.


The integrated applications or DApp model beyond the Polkadot parachain model, consists of the following:


The backend logic of the application is decentralized. users are more likely to interact with the chain than applications. The application is not a parachain, but a pluggable module. This is a palette that can be deployed (but not required) on the parachain.


You can deploy different backend modules for your application to different chains. For example, Zenlink's interchangeable pallets are used in multiple parachains.


Upgradeability-Application upgrades are flexible.


Application tokens are issued by command. Unlike smart contracts like the DeFi project on the EVM chain, integrated applications are not only decentralized and maintain the characteristics of smart contracts, but are also technically flexible.


For example, RMRK and Zenlink are pioneers of this type of application. You can integrate multiple palettes or submit runtimes across different parachains into the new DApp by taking advantage of the optimal performance of the different parachains. Using the integrated application approach, Zenlink provides an open and universal cross-chain DEX protocol to create DEX on Polkadot with one click, and RMRK brings standard cross-chain NFT infrastructure to Polkadot and Kusama ecosystems. Build.


Building the Blockchain Bridge As an established parachain member of the Polkadot crosschain ecosystem, the Phala network provides computing power to other blockchain applications while protecting the data layer. The Phala enables use cases such as privacy-protected DeFi trading positions and trading history, co-computing sensitive DID data, and Lightnode cross-chain bridges.


Today, Fara's Khala Ethereum Bridge offers the ability to trade ERC20PHA to the Khala chain with just one Ethereum trading fee. This marks the beginning of cross-chain compatibility and shows what the future blockchain network will look like. This bridging from Polkadot to Ethereum is achieved using the ChainBridge cross-chain communication protocol.
