Blockchain has experienced a recent “boom” among developers and companies aiming to improve visibility, ensure security, and expedite processes.It is obvious that adoption of blockchain technology will transform business operations and government operations, but doing so will take time and effort.
A recent study found that blockchain developers are now on high demand in the market. Around 1,05,000 blockchain engineers were thought to have worked in the industry overall in 2018.Globally, there are 18 Million Software Developers and this represent a fairly modest (small) percentage.
Despite this, the survey demonstrates that job growth in the industry is still increasing and this number will keep rising as governments and companies rank Blockchain technology in their top 5 priorities.
Who is Blockchain Developer
Blockchain developers are the IT experts who specialise in blockchain technology and are in charge of carrying out specific duties like creating smart contracts and designing the Blockchain protocols.A blockchain developer creates decentralised applications (dApps) based on blockchain technology in addition to being knowledgeable with the architecture and protocols of the technology.There are basically two types of Blockchain Developers –
(i) Core Blockchain Developers
(ii) Non-Core Blockchain Developers
Core Blockchain Developers
Developers who create the consensus and Blockchain protocols,, keeps track of the network architecture And Implement numerous blockchain functionalities & features. C++,Go and Rust are the programming languages used by Core Blockchain Developers .
Non-Core Blockchain Developers (Application based blockchain developers)
They basically works on the existing network of Blockhain technology .Some major roles of this type of developers are –
(i) creates APIs (Application Programming Interface) for integrating blockchain
(ii) Develop the backend and frontend for decentralised applications.
(iii) Create and implement smart contracts, etc.
Because it incorporates ideas from both computer science and other fields like banking and economics, blockchain technology may appear intimidating. But developing a blockchain is similar to mastering any other skill. Understanding the principles of blockchain technology should make it simpler for you to picture how more sophisticated notions fit into the picture.
SKILLS required for Blockchain Development
Web Development :
A key skill set for a blockchain developer is web development. Most blockchain developers who start their careers in the field are hired to do the fundamental designing of decentralised applications. This means that you must be familiar with the fundamentals of front-end and back-end programming, including tasks like designing interactive graphical user interfaces for Dapps, managing APIs, processing requests, etc.
Data Structures And Algorithm :
To succeed as a blockchain developer, one needs to have a thorough understanding and practical understanding of data structures. To suit their unique network requirements, blockchain developers are continually experimenting with and modifying pre-existing data structures like merkle trees, petrecia trees, etc. Blockchain creates a safe and immutable system by combining a wide variety of data formats with cutting-edge cryptography. Without any understanding of data structures, a knowledge of blockchain can only be characterised as incomplete.
Smart Contracts Development :
Since the introduction of Ethereum, smart contracts have gained tremendous popularity. Since business logic can now be put on the blockchain easily, every blockchain now strives to integrate smart contract capabilities into its system. As a result, developers wishing to work in the blockchain industry should undoubtedly learn about developing smart contracts.
One of the essential technical skills for becoming a blockchain developer is cryptography. To establish the groundwork for blockchain development, you must become familiar with a variety of cryptographic techniques, including digital signatures, hash functions, the RSA algorithm, and many others.
Tools required for Blockchain Development
Truffle is a programming environment that uses the Ethereum Virtual Machine as its foundation.
Truffle offers a variety of features, including:
(i) Truffle assists in managing the artefacts of any smart contracts used in your dApps through its “Smart Contract Management” service. You can concentrate on other stages of the development process while Truffle handles this. Additionally, this indicates that Truffle enables library linking, tailored deployments, and trickier Ethereum dApps.
(ii) Contract testing is supported by Truffle, which is even another beneficial feature. As a result, you can create automated tests for each of your contracts using your developer expertise in the twenty-first century. The primary advantage of this is that you can accelerate the creation of your smart contracts.
(iii)Deployment and migration scripts are scriptable with Truffle, allowing you to take into account the reality that your dApps will evolve over time. This indicates that you can continue to support your smart contracts for a very long time.
(iv) Truffle manages your artefacts for you, allowing you to concentrate on other activities while Truffle takes care of your network.
(v) Truffle has an interactive console that gives you access to all of the Truffle commands and contracts you’ve created.
With the aid of the tool Ganache, we may create a personal, regional Ethereum blockchain. The blockchain may be used in every step of the development process, which makes it a very helpful tool. Ganache enables us to deploy, create, and test all of our dApps in a secure and deterministic environment as we set up our local blockchain.
There are two versions of Ganache: Ganache UI and ganache-CLI, which is a CLI. Additionally, both of these Ganache versions are accessible on Linux, Mac, and Windows.
Gas fees must be paid in order to upload contracts to a real chain like the Ethereum mainnet. The costs may be incredibly large and unpredictable, which might be a concern. As a result, uploading contracts that are still not functioning properly might get very expensive.
Additionally, processing transactions on the real chains takes time, which is something we want to minimise while creating dApps. Therefore, we can resolve this by using Ganache to spin up a local blockchain where we can immediately implement smart contracts. As a result, Ganache can help us save time and money, which is quite helpful when starting a business.
The MetaMask software cryptocurrency wallet is used to interact with the Ethereum network.. Users can utilise a browser extension or mobile app to access their Ethereum wallet, which can then be used to connect with decentralised applications. ConsenSys Software is the creator of MetaMask.
MetaMask allows users to create and manage their own identities when a Dapp needs to carry out a transaction and write to the blockchain (via private keys, local client wallets, and hardware wallets like TrezorTM) . As a result, the user receives a secure interface to review the transaction before approving or rejecting it. When you browse to websites that are known to have engaged in phishing or that have names that seem suspiciously similar to well-known phishing targets, MetaMask can assist warn you.
HISTORY OF METAMASK
ConsenSys developed MetaMask in 2016. Before 2019, MetaMask was only accessible as a desktop browser extension for Firefox and Google Chrome. Given MetaMask’s popularity among bitcoin users and the fact that it hasn’t had an official mobile app for a while, incidents of malicious software misrepresenting MetaMask have made it difficult for Google to control its Chrome Web Store and Google Play platforms. In one case, Google Play accidentally removed the official beta version of MetaMask before reversing the action on January 1, 2020, a week later. MetaMask started releasing mobile app versions in 2019 for closed beta testing, then in September 2020 they made their initial public release for iOS and Android.
A built-in DEX aggregation service called MetaMask Swaps was implemented to the desktop extension in October 2020. In March 2021, the item became accessible via mobile devices.
