Why Should We Learn Solidity? Master Solidity Deploying the Era of Decentralization
Smart contracts are an indispensable part of blockchain. With a true sense of contracts running on a decentralized network, Solidity takes a very large share of smart contract writing and learning. Solidity is a mandatory subject for getting started with blockchain. Meanwhile, Solidity as the main programming language on Ethereum and most other major blockchain languages. Solidity developers will be able to play in many ecologies and markets. Mastering Solidity will bring developers a bigger stage and more opportunities.
According to relevant data, JavaScript and Solidity ranked first among the most commonly used programming languages (both 27%) among the most commonly used programming languages in 2021. While in the survey of respondents’ favorite programming languages, Solidity ranked second (19.4%), after Python.
Inseparable from the developers’ love for Solidity is the high salary it brings. As of May 2022, the median annual salary of Solidity developers exceeds £80,000, with both junior and senior developers seeing annual salary increases of 6% — 13%.
From the survey data, we can draw a clear conclusion: learning Solidity is a trend that will also bring advantages to career development.
After choosing Solidity, what is the next step in choosing a network that is suitable for Solidity novice developers to deploy and practice smart contracts?
As the EVM smart contract platform on Polkadot, Moonbeam enables developers to deploy existing Solidity smart contracts and Dapp front-ends on Moonbeam with minimal code adjustments. In addition, Moonbeam benefits from the shared security of the Polkadot relay-chain and the connectivity with other Polkadot-related chains, creating a secure and stable development environment and interoperable cross-chain functions for developers.
At present, more than 160 Web3 projects have been built and deployed on Moonbeam. Moonbeam has become an emerging dawn guiding the development of blockchain! Therefore, mastering and practicing Solidity skills on Moonbeam, not only being able to enjoy the huge users and markets brought by cross-chain multi-ecosystem, but also absorbing excellent project information and the latest technological progress from multiple perspectives. It is an important weapon for developers to achieve in-depth development of Web3.
In order to enable more enthusiasm to have a deeper understanding of the development and exploration of Moonbeam, OneBlock and Moonbeam have successfully held two sessions of “Moonbeam Advanced Solidity Development” course. It has attracted the attention of more than 5,000 developers, more than 100 students have mastered Solidity cross-chain skills through systematic course training, graduated as outstanding students, actively participated in various hackathon competitions, and put their projects on the market for testing.
Now, the first session of “Moonbeam Advanced — Easy Start Cross-Chain Solidity” is poised to kick off on October 18, 2022. This course includes 6 professional video lessons, 6 assignments, 5 course assistants provide Q&A and technical guidance to guide students into the practice of Solidity. We will award the title of “Outstanding Graduate” to those who have completed their study courses and assignments conscientiously. If you’re interested in this course, please slide directly to the second half of the article for registration.

In addition to the learning of recorded lessons, we have designed the homework covering important knowledge points and practical cases. There are 5 teaching assistants to answer students’ questions, follow up on the learning progress of students, and help students quickly apply what they have learned and quickly master the development process of cross-chain Solidity.
All in all, the course ranges from XCM principle design analysis to cross-chain deployment techniques using a variety of precompiled skills, making it easy to advance Solidity development and further reach the decentralized world.
Internal test participants sharing
A total of 10 developers were recruited for the private beta experience in this course, and OneBlock surveyed the developers who participated in the private beta. In the feedback received, most of the participants expressed their desire to learn more about the Moonbeam platform and Solidity development through the course, and to be able to try to build a top-of-the-line DApp through their own efforts. Out of curiosity about the Moonbeam and interest in Ethereum development, they have a desire to learn deeply, hoping to continuously improve their technical level to adapt to the development of Web3.
The following are some of the insights of the developers participating in the internal test and the teaching assistants in this issue:
@Yiwei Shi
At present, he is mainly engaged in the development of smart contracts and Polkadot Parachain.
Before that, although I had some experience with smart contracts and often used some template contracts on Ethereum, I never realized the limitations of these template contracts themselves, such as the complexity of some interfaces that need to be operated.
The Moonbeam Advanced section abstracts these interfaces, which greatly simplifies the entire business process and, more importantly, opens up some ideas for me. We can use the idea of being closer to the actual business scenario to re-encapsulate the original contract interface. In addition, this advanced course also made an in-depth introduction to some technical fields, such as the principle of random numbers and the basic knowledge of cross-chain and so on. They helped me to understand blockchain technology more deeply, and also made me think more broadly and professionally when building applications.
About how to learn: It is recommended that you have a basic understanding of Solidity and smart contracts, and it is best to write a few contracts before the class, such as ERC-20 contracts and blockchain games. In addition, the class keeps up with the rhythm of the teacher as much as possible, and some course content can be read repeatedly to strengthen understanding.
@Yifu Zhang
He currently works for a blockchain company that does privacy services. The main work is the development of smart contracts and the development of ts/js servers.
Moonbeam Advanced Course recommends everyone to try it. The threshold for advanced courses is not very high, as long as there is a foundation of Solidity smart contracts. In the advanced class, you can learn more skills in the Moonbeam ecosystem and more advanced Polkadot development knowledge. Although the advanced class will be slightly more difficult than the beginner course, everyone will definitely gain a lot by keeping up.
@Yalun Peng
Moonbeam is the most compatible parachain of Ethereum in the Polkadot ecology, and it is also one of the Polkadot head projects. Learning Moonbeam can make it easy for you to have both Ethereum and Polkadot ecosystems!
The advanced course is still the same high quality as the introductory course, the depth and breadth are both well. Henry’s teaching is still so good. But relatively speaking, the difficulty of advanced will be much higher, requiring a lot of reading of docs and various external materials.
Come on! Everybody! Web3 is waiting for you!
@Ping Wang
Zhejiang University of Science and Technology graduate students in blockchain direction.
Yunphant Chain in-service (Alliance Chain Baas development); Yun Miracle (DAPP development contract development, product design); He won Polygon best student project; third prize of Zhejiang University Chain Square Cup (7/40).
In the advanced course, you will learn more about cross-chain related knowledge and the underlying blockchain foundation. Moonbeam course is also very attentive. If you want to learn, please seize the time.
@Ao Wang
Substrate Evangelist / Blockchain development enthusiasts
Henry introduced xTokens Pallet and pre-compile in detail, and through the advanced course I also learned about the newest technology in Polkadot, the Cross Consensus Message Format (XCM) protocol. Although the XCM message implementation is still in its early stages, we were able to learn the two most common use cases in the Moonbeam course: asset transfer and remote transfer. We hope that interested developers will learn the latest Polkadot & Moonbeam technologies.
