Whether you’ve been aboard the hype train for many years or have absolutely no idea what it is, you can’t deny that Blockchain remains one of the hottest topics in the tech industry. Besides the obvious attraction of Bitcoin and other cryptocurrencies, blockchain technology has huge potential in other spheres of life, such as healthcare, insurance, real estate, surveys and voting, copyright payments, logistics, and much more.
In recent years, more and more people have been trying to enter the blockchain development market, but the requirements are quite difficult to meet. Each developer must be familiar with a specific set of tools and constantly improve their skills in order to secure a profitable job and stay in the crypto game for a long time.
Here is the list of essential programs, languages, and frameworks that hold the keys to blockchain proficiency.
Note: this list is based on the most popular blockchain platform, Ethereum, however, most of these tools will work with other platforms, like Hyperledger Fabric or R3 Corda.
Solidity is a programming language designed specifically for the Ethereum Virtual Machine (EVM) with the main focus of creating smart contracts. However, it’s far from being a one-trick pony.
Besides smart contracts, Solidity can be used for all kinds of computing tasks thanks to its Turing completeness and support of many popular functions and structures. The large community is constantly working on adding new features to make Solidity even more versatile and potent.
Rust is another language on the rise that thrives in the blockchain environment. It’s built with speed and performance in mind, ditching garbage collector and reference counting altogether, making it one of the fastest and most efficient languages around (yes, even faster than C++). It can be used for both functional and system programming, and it’s a great tool for implementing smart contracts, helping you expand your business
Rust is often called the most-loved programming language in the world, with people praising its intuitive compiler, advanced toolkit, and extensive documentation. The only downsides of using Rust are somewhat strip-down libraries and wordy scripts.
When it comes to creating smart contracts, it’s hard to beat the incredible functionality of Truffle. It’s a development framework that utilizes the EVM and offers a variety of customizable options for quick and easy contract management such as:
- Deployment script support;
- Interactive console with access to all contracts;
- Artifact management (contracts + network);
- Dedicated script runner.
Truffle is equally effective for Ethereum, Quorum, Hyperledger, RSK, and virtually every other blockchain, so its popularity should come to no one’s surprise.
The testing process, powered by popular libraries like Chai, is a breeze, and so is the contract integration courtesy of the OpenZeppelin plugin. Plugins, in general, play a huge role in Hardhat’s success, allowing developers to freely experiment with their builds.
Remix is an integrated development environment that’s accessible from a web browser or a desktop app. It covers the whole process of smart contract creation from writing to deployment, and it can also be used as an Ethereum sandbox of sorts for educational purposes.
As you know, you can’t mess with a blockchain once you add new data to it. Ganache gives developers the opportunity to simulate their decentralized applications (dApps) before rolling them out to Ethereum. It’s basically a local blockchain with all of the features of the original Ethereum platform plus several unique testing tools for more development control, like log output, mining configuration, and built-in block explorer.
The main advantages of Ganache are no transaction fees and instant contract implementations. Saving time and money is what business is all about, and with the help of your own personal blockchain, you’ll have plenty of both to polish your apps to perfection, and help your business grow
Ganache is a part of Truffle Suite, along with the aforementioned Truffle framework and Drizzle (a collection of front-end libraries).
Every blockchain platform has an alternative testing environment where developers can dummy run their smart contracts without the fear of losing money. Testnets let you earn and spend cryptocurrency, although it has zero value but is useful for testing purposes as part of your development lifecycle.
The best Ethereum testnets in 2022 are:
When you start earning crypto coins, you need a place to store them. MetaMask is a browser-based digital wallet that serves this purpose quite well, but it doesn’t stop there. Besides keeping the keys to your Ethers and ERC20 safe, MetaMask opens the door to the entire Ethereum blockchain, allowing you to interact with dApps and testnets via Firefox or Chrome.
It’s one of the most popular wallets in the crypto world, with more than 20 million users, competing for the top spot with the likes of Coinbase, Ledger, and Trezor.
Trezor has been around for as long as Bitcoin itself, and in 2022, it still gets the job done. Trezor supports over a thousand currencies and has an unmatched security setup. The PIN code is unique to each login and stored within the wallet itself. If the code is guessed incorrectly, you have to wait twice as long before you can try again. There’s also a special phrase to enter after you’re done with the PIN, so good luck breaking someone’s Trezor account.
Also known as Go Ethereum, Geth allows developers to run an Ethereum node in Golang, which is a statically-typed open-source programming language. With the help of Geth, you can not only join an Ethereum network but also execute smart contracts, mine crypto coins, and transfer them to other accounts.
Geth is easily accessible and actively supported by the community, making it one of the most useful blockchain tools for both beginners and crypto veterans.
So, there you have it, 11 great tools that every blockchain developer should know. Master these and you are guaranteed to get noticed and become a valuable part of the blockchain industry.
