Polkadot opened an era
In this round of cryptocurrency bull market, the hot spot besides DeFi is Polkadot. Although the Polkadot Parachain Slot auction on Polkadot's mainnet has not yet started, there are already a lot of projects developed in the Polkadot ecology. Only the Web3 Foundation grant supports more than 200 projects (distributed in more than 50 Countries), the Polkadot ecology is getting more and more prosperous.
The reason why Polkadot has received widespread attention from the market is mainly because compared with other blockchain projects, Polkadot has opened an era. Before Polkadot appeared, there was no interaction between various blockchain networks. Information islands, the so-called "stand-alone era", with Polkadot, each block chain can interact with each other, and the world of block chains has also begun to move towards the "Internet era" of 10,000-chain interconnection, just as the Internet is revolutionary.
Polkadot is positioned differently from other public chains. Compared with other public chain projects, Polkadot is a lower-level infrastructure. In Gavin Wood’s view, the future blockchain world will be multi-chain coexistence. The main function of the card is to connect these different blockchain networks together, and these connected blockchain networks can interact with each other.
In order to realize this great vision, Polkadot has introduced the basic structure of "relay chain-parachain". After the parallel link is connected to the Polkadot relay chain network, it will not only interact with each other You can interact with each other and share Polkadot’s consensus security, so you can spend more time focusing on your own business.
Polkadot parachains are divided into isomorphic parachains and heterogeneous parachains. Since Polkadot is developed using the Substrate framework, the parachains developed using Substrate can be called isomorphic parachains. After all, the underlying structure is the same. As the name implies, the parachains are different. The underlying structure of the parachain is different from Polkadot. For example, Bitcoin, Ethereum, EOS, TRON, etc. can all be used as Polkadot's parachains to connect to Polkadot. The underlying structure of these blockchain networks is obviously different from Polkadot. They are different, so they are called heterogeneous parachains, and heterogeneous parachains need to pass through a bridge to access the Polkadot network.
For a blockchain project, the same development framework Substrate as the bottom layer of Polkadot can be used for development, so that it can be directly connected to the Polkadot network without passing through a bridge.
Substrate framework lowers the threshold of blockchain development
As we all know, Polkadot has revolutionized the Substrate development framework for blockchain developers around the world. The framework modularizes the basic underlying design of the blockchain, allowing developers to call with one click, saving the original complicated workload. .
Before the advent of Substrate, it was very troublesome to develop a custom blockchain. It needed to consider factors such as security, upgradeability, expansion, and cross-chain, and required a lot of coding and testing. Developers need to have a sufficient in-depth understanding of the technical issues on the p2p network, consensus protocol and other chains.
In the process of developing Polkadot, Gavin Wood found that many blockchain networks did the same things, such as consensus security, scalability, etc., so he felt that these repetitive things could be encapsulated and abstracted as "Development framework" means "making wheels", and those who use this "framework" for development can focus more on their own business logic without having to spend a lot of energy repeating "making wheels".
Therefore, Gavin Wood abstracted the existing achievements of Polkadot and Ethereum and named Substrate as the basic framework for blockchain development. Substrate is the first "wheel" of the blockchain world.
The Substrate development framework is composed of many ready-made functional modules, such as Staking, Consensus, and contract modules. When using this framework for development, blockchain developers can freely combine and customize these modules according to their business needs. , There is no need to reinvent the wheel, thereby reducing the development threshold of block projects and greatly improving the development efficiency of block chain projects. If Ethereum enables one-click issuance of coins, then Polkadot also enables one-click chain issuance with the Substrate development framework.
Subscript further reduces the barriers to blockchain development
Although the Substrate framework lowers the barriers to the development of blockchain networks, Substrate's native smart contracts use a Rust-based ink! language. The language has a relatively large learning difficulty curve, and many traditional web developers are not familiar with the this language. Therefore, the high barriers for Polkadot blockchain development make it difficult for a large group of traditional web developers to enter, which is not conducive to The long-term development of Polkadot ecology.
There will be a market if there is demand. In order to help traditional web developers and Java engineers to participate in the construction of the Polkadot ecosystem without barriers, TrustBase independently developed the lightweight WASM smart contract language Subscript to meet the needs of traditional developers to break through industry barriers and promote the realization of Web3.0
TrustBase brings together the advantages of Polkadot, and at the same time provides developers with a low-threshold Subscript language and various development "kits", which will continue to attract other developers to join the Polkadot ecosystem. The Polkadot ecology is of great significance to the blockchain world, and TrustBase is expected to lower the barriers for developers to enter the Polkadot ecology.
