On February 23, the Ethereum programming language Solidity launched the 0.8.19 version of Solidity compiler. The latest version includes a series of improvements and the introduction of user-defined value type definition operators to prevent dead code in bytecode at runtime@ Problems with internal library functions and free functions called through modules reported by sifislag have been fixed in this version. The team recommends that users who use Solidity version lower than 0.8.0 upgrade.
Solidity compiler released version 0.8.19, introducing user-defined value type definition operator
Interpretation of the news:
Solidity, the programming language behind Ethereum blockchain, has recently launched version 0.8.19 of its compiler, bringing several improvements and a new feature for preventing dead code in bytecode at runtime. The release notes highlight the introduction of user-defined value type definition operators as the primary addition in this version.
Value type definition refers to the ability to set up user-defined types that encapsulate a piece of data and its associated operations. In the previous version, Solidity only supported library functions, built-in types, and structs as value types. However, the new version enables developers to define value types using operators analogous to those used for creating contract types.
One of the significant benefits of user-defined value types is their ability to prevent dead code in bytecode. Dead code refers to code that is not executed during the runtime of a contract but is included in the bytecode. This code can lead to unnecessary gas usage, an increase in the size of the contract, and potential security issues.
By defining value types explicitly, developers can avoid defining unnecessary code, thus reducing the potential for dead code. Moreover, the new feature saves developers the hassle of creating structs for every piece of data that they want to store, simplifying the process of writing smart contracts in Solidity.
Another crucial improvement in Solidity version 0.8.19 is the fix for problems with internal library functions and free functions called through modules, which were reportedly reported by sifislag. This means that the latest version is more stable and secure than previous iterations.
The Solidity team recommends that users who are currently using a version lower than 0.8.0 upgrade to the latest version to enjoy the new features and improve their smart contract development experience.
In conclusion, Solidity’s 0.8.19 version is a significant milestone in the development of the blockchain programming language. With user-defined value types and fixes for internal library problems, the new version promises to deliver more secure and stable smart contract development.
Overall, the improved compiler and introduction of user-defined value types through definition operators will make Solidity more convenient to use, reduce dead code expressions, and minimize the chances of errors occurring within the smart contract. This update is sure to be welcomed by many Solidity users.

It means changing the name of a token to a token. coin In traditional trading platforms, the process of users exchanging tokens through buying and selling is called “buy out” behavior, and this phenomenon is already very common. For example, in order to make the purchasing process more convenient for users, exchanges will use a method called “sell out” or “pull order”. This approach can also reduce risks and increase profits for users. However, due to the large amount of false information and opacity in the current market, investors are often deceived by scammers. So, for these scams, they are of no value In fact, this problem can also be solved through the creation of tokens.
