🦊 Reasons to move into Web 3 Development

💸 High compensation: In the dev community, blockchain is considered to be a highly monetary niche. This is confirmed by statistics: the average salary of a middle developer on blockchain projects is 11% higher than programmers in the market, senor - by almost 15%. And salaries at major cryptocurrency exchanges and blockchain companies are as high as in FAANGs

👨‍💻 Simple requalification: This is where it's important to understand what Web3 is all about. It's not just working with blockchains and smart contracts. In any Web3 application, there is also front-end and back-end where specific languages are not required. It is important to understand the blockchain architecture and how to interact with it, what smart contracts are and their interaction

💻 Frontend in Web 3.0: From a technical side, there is not a big difference between front-end code for Web2 and Web3. The difference is in how Web 2 and Web 3 applications handle data - the handling of data mutation changes. Whereas Web 2 simply sends requests from the user to the backend, Web 3 data mutation needs to send a transaction with a smart contract call to the blockchain

❔How to safely explore the realm of Blockchain

Let's learn the basics of crypto security for those who are just moving into web3:

🗝 The first and foremost rule is never share your seed phrases. Knowing the seed literally allows an attacker to take control of your money.

🔐 Two-factor authentication - an extra layer of protection is certainly a good one to have.

💰 Diversification - the main fault of inexperienced enthusiasts and dreamers is to invest heavily in a certain project. You need to invest in multiple assets to reduce the risks of burnout.

📚 Education - crypto is one of the fastest changing fields atm, to be a guru in blockchain you need to be up to date daily and constantly learning. Check smart contracts, study tokenomics projects, read current news, etc.

🌚 And of course, keep an eye on Top Selection so you don't miss the next portions of useful content from the world of mysterious Web3

🥈 Web 3.0 is an emerging and very dynamic field, but it may also be more challenging for developers because of the novelty and specificity of blockchain technologies

📝 The relatively short history of Web 3 development can involve challenges for developers who are looking to move from Web 2 to Blockchain development, especially in the early stages of the interview round

❔How to prepare for interviews for companies like Binance, Polygon, 1inch, etc.? What questions to expect and how to answer them accurately in order to be selected?

Top Selection team along with top developers and recruiters from partner crypto projects will help you to prepare for the interview and make onboarding with the help of test and mock interviews. Currently we are presenting 3 main types of interview preparation for those who want to get a job in the Web 3 👇

🔹 Technical Interview Assessment

🔹 Technical Mock Interview (Q&A)

🔹 Technical Mock Coding Interview (Q&A + Live Coding)

Half a billion are on the way!

🔝The number of crypto users worldwide has reached 418 million people. This was reported by k33research portal

🇨🇳The largest number of crypto adopters reside in Asia - 262 million people or 63% of the total number of users

👥 Meanwhile, the crypto industry employs more than 187 thousand people, which exceeds the indicators of the largest technology companies Google, Apple and Facebook. The majority of hired employees are from Asia - 65.9K, another part (60.7K) is from North America, and the remaining third of employees are from European countries, South America and Africa.

What does this mean for the crypto industry?

🔸 418 million users is a growing figure that will reach a billion in a few years. This shows that mass adoption of crypto technology is approaching.
🔸 Most of the market is concentrated in Asia. Startups that want to attract users and generate revenue will enter the Asian market.
🔸 This large growth in users creates a need for specialists to deal with it, especially blockchain developers, as serving half a billion users is not an easy mission.

🐂 We see more and more people joining crypto, so the bearish mood is gradually changing into a positive side

🔓 What is a Cryptocurrency Audit and why is it needed?

While cryptocurrencies offer a "new generation of payments" with fast transactions, low fees and increased privacy, its users face a record number of risks and issues

What is a crypto audit?

✒️ A cryptocurrency audit is a review of whether the technical metrics of a cryptocurrency match the company's claims and whether the coin is protected from hacker attacks. The purpose of the audit is to make sure that the cryptocurrency is free of bugs and critical vulnerabilities.

📄 Following the audit, the auditor issues a report that is useful to both the project issuing the cryptocurrency and to users or potential partners. Cryptocurrency developers can fix the vulnerabilities found by the auditor. And if there are none, the report will be a green flag for investors and customers who don't have to worry about the safety of their investments.

Why is an audit necessary?

✅ Firstly, it helps to identify projects aimed at making money fraudulently. Secondly, auditing can also help to identify technically weak coins that do not live up to their promises or have poor security. In both the first and the second case, audits reduce the risks of investing in cryptocurrencies.

Cost of auditing

ℹ️The cost of auditors varies depending on the size and complexity of the task. The owners of a large crypto exchange will have to pay several times more than the founders of a small startup. The point here is not the number of users, but the length of the code to be audited.

💸 On average, an audit can cost from $5,000 to $50,000 - companies do not give exact figures without a preliminary analysis of a specific situation.

🧑‍💻Therefore top Auditors of smart contracts DeFi protocols like Hacken, CertiK and others are actively seeking blockchain specialists from simple testers to expert cybersecurity specialists

Future Trends in the Blockchain 📈

ℹ️ Blockchain developers, unlike their Web 2.0 folks, need to be always on the lookout for new knowledge and keep up to date with the latest market trends because blockchain is one of the fastest growing areas of all possible and new networks and blockchains, as well as related technologies and functionality, are constantly emerging in this market. To stay ahead of the competition or to be prepared for any unexpected questions in the interview, we have prepared a list of upcoming trends in the blockchain industry that may dominate in the near future

🔸SVM
Solana Virtual Machine (SVM) is attracting more and more attention from developers and has chances of widespread adoption. This is due to the experiments and innovations this technology can bring: new sequencers, new rollups, new applications and new liquidity.

🔸Modular vs Monolithic structures
This trend is also related to the adoption of SVM, which will be one way of modular innovation. Modular technologies allow for accelerated experimentation. For example, Solana is now modular at the technical and community level.

🔸Appchains
Blockchains created for specific applications will also attract the attention of users and developers. The main reason for creating appchains is sovereignty and the possibility of forks. This is the reason for the creation of the MakerDAO appchain.
