All You Need To Know About Web 3.0 And Blockchain
Learn about the new trends.
Introduction
New technologies make the rounds in the tech world now and then. Given the nature of developers, learning about these new trends is critical, especially if you belong to a group of developers or you are looking to transfer to something new and more challenging.
At the moment, Web3 and Blockchain are all the rage, and this article will give you prior knowledge on these topics.
This write-up will let you understand very well the meaning of important terms, facts about web.3 and ways you can transition from wherever you are to blockchain development.
After reading this article, You will have sufficient information to decide whether to enter the blockchain development industry or not, whether to use blockchain in your upcoming project or not.
What are blockchain, smart contracts, and the web3?
Blockchain
A blockchain is a data structure used to create a decentralized ledger. A blockchain consists of blocks that are chained serially. A block contains:
A timestamp indicating when the block was created
Block reward
A set of transactions
Block number
A hash of the previous block
Every block contains a hash of the previous block, thus making a chain of blocks linked with each other. Every node in the network holds a copy of the blockchain.
Blockchain is still hot and the industry has a crazy amount of demand for developers right now. Next to awesome salaries, it's also an immensely interesting field to work in.
If you want to be a part of this and advance in your career to become a Web 3.0 developer, a structured approach can leverage your learning a lot.
Here are videos that teach everything you need to know about blockchain
Smart Contracts
Smart contracts are a great option for automating complicated business processes and transactions since they are transparent, secure, and impervious to tampering. They are created in code and kept on a decentralized blockchain network, which makes sure that everyone has access to the same data and that the rules of the contract are automatically enforced without the involvement of a middleman or outside party. Finance, real estate, and supply chain management are just a few of the sectors using smart contracts to improve efficiency, cut costs, and streamline procedures.
Smart contracts can nearly do everything, from fungible and non-fungible tokens to the backend of your next decentralized app. They are, however, different from the code you usually write. They will make up a good portion of your future work, so better understand them well.
Web 3.0
The next generation of the internet, referred to as Web 3.0 or the decentralized web, is based on decentralized technologies including blockchain, peer-to-peer networks, and distributed storage. It intends to develop a more open, transparent, and user-centric internet that is owned and regulated by the users themselves rather than a small number of centralized companies. With Web 3.0, users should have more control over their data and online identities and new applications and services that are more secure, private, and resistant to censorship.
Blockchain, decentralized applications (dApps), smart contracts, decentralized finance (DeFi), and other technologies and ideas are all included under the umbrella name "Web 3.0."
Web 3.0 was originally termed the Semantic Web by Tim Berners-Lee, and was portrayed to be an autonomous, intelligent, and open internet.
Learn Solidity
Solidity can be learned. There are numerous blockchains available, each with its distinct method of constructing smart contracts.
Solidity, on the other hand, is the language of the Ethereum Virtual Machine (VM), which is embedded in many other blockchains. It will not only benefit you on Ethereum. It will also assist you in creating smart contracts on other chains.
Solidity developers have by far the most job opportunities. Many companies are building or planning to develop on Ethereum. It may be a long time before another blockchain reaches the degree of adoption that Ethereum has.
Despite a few issues (the chain is now overloaded), the community is actively working on shifting the consensus to Proof-of-Stake. All scalabilitySolidity can be learned. There are numerous blockchains available, each with its distinct method of constructing smart contracts.

What you must understand in particular is how gas works and how each line of code you write in Solidity influences the price of execution of your smart contract. There is no getting around that. Unfortunately, some businesses aggressively optimize for gas use.

Is Blockchain The New Oil Money?
If by oil money you mean blockchain development is profitable, then the answer is yes! Blockchain developers, for example, were expected to earn between $150 000 and $175 000 on CNBC. According to a popular LinkedIn job posting, a senior blockchain developer might earn up to $1 million per year.
While money is a key motivator for almost all developers to branch out into new areas, usefulness and enthusiasm for work must also be considered.
Can I Become a Blockchain Developer?
Do you want to know if you can become a blockchain developer? Yes, why not? You only need to learn the tools and principles to be successful. If you are wondering whether it is worthwhile to venture into Web3, examine the following facts: The Internet, like all other technologies is changing. We witnessed the power and utility of Web 2.0 from Web 1.0. Web2 will not always be the sole option to create online applications. This is especially true for FinTechs. At the time of writing, the entire Web3 sector is booming, if you're in any tech group, chances are you've come across the word or a developer in it. Blockchain has the potential to be the web Future.
What Are The Programming Languages?
Solidity: Solidity was designed to be similar to JavaScript to make the transition easier for JS developers. Solidity is the most in-demand expertise in the Web3 arena, and it is utilized for Ethereum client dApps and smart contracts.
Python: Because of its popularity and ease of use, Python has gained widespread acceptance in Web3. The pyethereum project, as well as the web3.py project are examples.
JavaScript: As the most popular web language, JavaScript offers modules that are specifically designed for Web3. Etheruem.js, Three.js, Ethers.js, Web3.js, and other examples are available.
Rust is a C/C++-inspired language that is used to create Solana client dApps and smart contracts. Rust was used to create the Parity client.
.NET: The.NET framework is not forgotten. Using Nethereum, you can simply connect the Ethereum blockchain into your.NET apps.
C++: C++ is primarily qualified. You can never go wrong with the language for protocol development.
Golang: The powerful Go language has also demonstrated skill in the web3 sector. The Geth client, for example, was developed in Go.
Where is the money at?
Many organizations are looking for blockchain talent, and Google has lately moved into the area, so you can cash in on your skills. You can earn money in this block by doing one of the following:
Hackathons.

Conclusion
You have now seen and comprehended everything necessary to begin working with blockchain technology. If you have the time and motivation to learn a new set of tools and technologies that are likely to shape the Internet of the future, you should do this. Even more, businesses will enter as a matter of survival as more declare their entry into Web 3 For developers, this means more money and business opportunities.
Still interested?
Don't be discouraged if it takes some time, especially if you don't have a lot of industry expertise. Some organizations may aim to recruit more experienced employees.
I am rooting for you!
