Ethereum Updates Its Solidity Programming Language For More Versatility Ethereum, the second most popular cryptocurrency in the market, updated its Solidity programming language to give it more versatility while reducing the chances of errors. Ethereum’s creator Vitalik Buterin said that by changing certain syntax rules, Solidity can become more opinionated and thus less prone to programmer mistakes.

Ethereum’s creator Vitalik Buterin said that by changing certain syntax rules, Solidity can become more opinionated and thus less prone to programmer mistakes.
The new version was released with the aim of improving the performance and simplifying the user experience. It corrects bugs, adds functionality, and increases security by including more checks in the development process. Now it is much easier to identify bugs during dynamic deployment. Additionally, there are minor changes that improve the overall performance of smart contracts written on the official Solidity blog. Ethereum Updates Its Solidity Programming Language For More Versatility.
The main development for this change is to allow the usage of Solidity with different IDEs, such as Qt Creator or VIM. The integration follows with a process where the added Solidity will create an IDE friendly environment which provides users the ability to operate development tools such as compilers, documentation, and even autocompleted support now. Those interested can access the official blog to know more about the particular installation according to the IDE used.
Microsoft’s Visual Studio Code is now one of the most widely used programming IDEs to date with one million active community members. Although Microsoft’s IDE doesn’t support Solidity syntax autocompletion today, LSP support is expected to be added shortly. These notes were taken from an interview with the product manager, who stated: “[Visual Studio Code] will add support for additional languages and extensions in future releases based on developer demand, so we are looking forward to seeing how well this one performs in practice before making a decision either way.
Language level improvements Ethereum Updates Its Solidity Programming Language For More Versatility
In addition to the improvements made to Solidity’s development tools in terms of using them with other programming environments, the core developers have also improved solidity’s internal abi.encodeCall method. This optimization allows for faster data verification, as opposed to encoding it via abi.encodeWithSelector which was used previously.
This can be considered a small improvement to the process of translating code into executable pieces on Ethereum’s virtual machine by which computations are performed, called the Ethereum Virtual Machine or EVM. Computational costs are always something to consider when writing smart contracts in Solidity. The EVM produces computations and executes them up until such a point that input data or previously-computed output from the blockchain is no longer necessary. Logic within smart contracts are executed serially, meaning once line 1 runs, all necessary steps must be complete before line 2 can run. If that same piece of code is used frequently (e.g. gasTokenTransaction() ), every single time it will generate more computational work than it needs as EVM doesn’t realize that line 1 was already ran successfully.
Ethereum, as a Blockchain Platform for developing decentralized applications Ethereum Updates Its Solidity Programming Language For More Versatility
Blockchains offer multiple platforms for developers to work on and come up with new smart, blockchain-based projects. Ethereum is one of those platforms. When smart contracts can be used to disseminate data over a given blockchain through various nodes, not only does this allow easy access to the data itself but also it allows users to interact with the data much more easily than they would otherwise!
The Ethereum Blockchain is a potential distributed infrastructure that facilitates you to complete projects using smart contracts.
Steps to develop an Ethereum Smart Contract Ethereum-updates-its-solidity-programming-language-for-more-versatility.
In order to connect to Ethereum, MetaMask would need to be installed. To install it go to the link MetaMask and click “Add To Chrome”. Once this is completed, you may now experience what it feels like to actually create an identity within the Ethereum Blockchain. You can now proceed by clicking on the MetaMask icon in the top right of your browser tab (if you’re using Google Chrome). This will open up the DApp where you can create an account which will take a couple of steps.
Select any one test network
You might also find the following test networks in your MetaMask wallet:
- Robsten Test Network
- Kovan Test Network
- Rinkeby Test Network
- Goerli Test Network
Add some dummy Ethers to your wallet
If you want to try out MetaMask, there is a sampler feature that allows you to play with dummies using the Robsten test network. Make sure your MetaMask configured as a Robsten test network. You will see 0 ETH under your account and we’re providing 5 ethers for testing purposes via the deposit and get some more button generated by MetaMask itself.
Use editor remix to write the smart contract in Solidity
We will use Remix Browser IDE to write our Solidity code. The remix is the best option for writing smart contracts as it comes with a handful of features and offers a comprehensive development experience.
It is usually used for writing smaller-sized contracts. Remix’s features include:
- Warnings like gas cost, unsafe code, checks for overlapping variable names, whether functions can be constant or not
- Syntax and error highlighting
- Functions with injected Web3 objects
- Static analysis
- Integrated debugger
- Integrated testing and deployment environment
- Deploy directly to Mist or MetaMask
Create a .sol extension file
Open Remix Browser and click on the plus icon on the top left side, next to the browser to create a .sol extension file.
A sample smart contract code to create ECR20 tokens
ERC20.sol is a standard template for ERC20 tokensERC20.sol is a standard template for ERC20 tokens
Select a version of the compiler from Remix to compile the solidity Ethereum smart contract code.
Deploy your contract
Deploy the smart contract at the Ethereum test network by pressing the deploy button at the Remix window’s right-hand side.
Wait until the transaction is complete.
After the transaction commits successfully, the address of the smart contract would be visible at the right-hand side of the remix
At first, all the ERC20 tokens will be stored in the wallet of a user who is deploying the smart contract.
To check the tokens in your wallet, go to the metamask window, click add tokens, enter the smart contract address and click ok. You would be able to see the number of tokens there.
