Why does Polkadot need to change? What is Polkadot used for?

Why does Polkadot need to change? Why does Polkadot need to change? Why does Polkadot need to create a “parallel chain”? It has two core components: the relay chain and the relay chain. The second is the bridge (RelayChain).

Over the past period, Polkadot has been dedicated to providing interoperability and privacy features to blockchain networks, and plans to add some new components and application use cases to promote the development of the ecosystem, including KusamaNetwork supported by Substrate and Web3 Foundation’s development team at Parity Technologies. However, these changes are not completely decided by the community, so we believe that this is not a breakthrough in core technology that Polkadot can achieve. Why does Polkadot need to do something? Because Polkadot, as a scalable and decentralized smart contract platform, is designed to solve problems faced by blockchains, such as data availability and demand for block space. However, due to the inability of different blockchains to communicate, Polkadot does not allow users to schedule or change their own state through individual validator nodes, but requires multiple validators and multiple independent running applications to manage their transactions. In addition, in order to be compatible with Ethereum, Polkadot has established a tool suite specifically for building and deploying decentralized applications – Substrate-SDK. Without this framework, no new smart contract language will be created, and no new functional modules will be generated.

So when you want to use Substrate, you must first update your software version, and then start rewriting your code library and migrate it to the mainnet before the next upgrade. This allows developers to easily launch new projects without complex network settings. This change not only leads to performance degradation, but also affects other aspects, such as improving security levels and stability. The main innovation of Polkadot is to shard the blockchain into smaller parts, so that these different types of data can be utilized while sharing security.

Unless you choose to switch between all parallel chains to another parallel thread, you can never access their public APIs or services. You can access the parallel thread by executing any command on it and obtaining the required approval, without additional infrastructure.

If you want to see information about the new developments of Polkadot, please follow the following article: How to participate in Polkadot v0.8.1. One of the biggest innovations of Polkadot is the integration of cross-consensus. PolkaWorld hopes to help everyone understand more about what Polkadot is and its main improvements.

1. The Polkadot protocol aims to simplify cross-client interaction and interoperability.

2. Smart contract architecture based on Substrate.

What is Polkadot used for? Let’s first take a look at what DOT is. It is a blockchain technology solution that can connect blockchain with other systems to create interoperability and allows anyone to use the smart contract functionality of the network.

Simply put, Polkadot is a new form of application brought to developers and users around the world by a secure and decentralized technology composed of relay chains and parallel threads. By deploying and maintaining on the mainnet, each project can become an independent network, and they all have their own economic interests and governance mechanisms. But if you want to participate in the ecosystem, you need a public ledger or public blockchain as the underlying layer.

And this is exactly the relay chains and parallel threads built on the Substrate framework. They can provide power and security for the operation of the entire system. These side chains are called “relay bridges”, which are communication channels between cross-chain protocols and blockchains used for multi-party computation.

To achieve this goal, Polkadot proposes a new structure. This design aims to address the functional deficiencies that the Ethereum virtual machine (EVM) cannot achieve – even if its performance is unstable, it can be made more user-friendly and scalable through techniques such as sharding. This architecture ensures that all different types of applications can seamlessly switch between the same set of blockchains; therefore, since they have different consensus algorithms, it is not necessary to rebuild multiple blockchains, and it is difficult to start blockchains on a separate chain, but from another perspective, Polkadot supports a variety of blockchains. So, why join ecosystems like Kusama and Polkadot? Because each of these ecosystems is a unique blockchain, they must be compatible at the same time.

For example, the second parallel chain AcalaNetwork on Polkadot has obtained funding from the Web3 Foundation (https://web3.foundation/). With the development of Polkadot, it is gradually replacing Ethereum and entering a more decentralized platform, allowing more companies to deploy applications on Polkadot.

Currently, Polkadot is still in a very early stage. Although there have been many news recently that Polkadot will launch the mainnet soon, Polkadot founder GavinWood tweeted that he expects to release the first parallel chain this year.
