Introduction
Following extensive research across numerous platforms, such as the Solidity GitHub repository, the roadmap for Solidity, an in-depth analysis of community dialogues on Twitter, and a detailed examination of active Pull Requests and Issues, this article offers an in-depth look at what the future might hold for Solidity.
The upcoming releases, 0.9.0 and 1.0.0, of this leading smart contract programming language are poised to roll out several eagerly anticipated enhancements.
This article aims to inform readers about the latest developments and improvements in Solidity, which are based on the community’s input and ongoing debates. While the information provided is not conclusive, it sheds light on the potential technological advancements.
1. Revolutionizing require()
with Custom Error Integration
Current Approach (0.8.x):
error UnauthorizedAccess();
if (condition) {
revert(UnauthorizedAccess());
}
Expected in 0.9.0 or 1.0.0:
error UnauthorizedAccess();
...
require(condition, UnauthorizedAccess());
Using require() with custom errors enhances clarity and gas efficiency compared to using string messages or custom Errors with extensive if conditions.
2. Internal Representation (IR) Optimizations: Unleashing Efficiency
The process of Internal Representation (IR) in Solidity plays a pivotal role in converting written Smart Contracts into executable instructions for the Ethereum Virtual Machine (EVM).
It simplifies and standardizes complex code, making converting code into machine language more efficient. The forthcoming improvements in Solidity 0.9.0 aim to make this compilation process faster and more efficient, ultimately reducing costs and enhancing developer productivity.
3. Enhanced Error Handling: Clarifying and Streamlining Code
Future updates are expected to enhance error handling in Solidity, leading to more straightforward error messages and easier debugging.
This enhancement will be especially useful for developers dealing with intricate contracts, saving time and minimizing potential mistakes.
4. Fixed-Point Arithmetic: Precision and Performance
Currently, external libraries like ABDKMath64x64 and DSMath facilitate fixed-point arithmetic in Solidity.
The expected update in version 0.9.0 is set to integrate native fixed-point arithmetic support, rendering external libraries unnecessary and making calculations with fractional numbers more streamlined.
5. EVM Object Format (EOF): Structuring Smart Contract Bytecode
The potential upcoming EOF upgrade in Solidity is poised to introduce structured and version-controlled bytecode for smart contracts.
This advancement promises easier implementation of future updates, maintaining backward compatibility, and enabling more effective analysis at the compilation stage.
While this won’t alter the direct coding experience for smart contract developers, the output from the compiler is expected to be more gas-efficient.
6. Transient Storage: Temporary and Efficient Data Handling
Solidity’s new feature, transient storage, proposes a method for temporarily holding data during the execution of a contract without permanently recording it on the blockchain. This approach is anticipated to be more efficient in terms of gas usage. Learn more about Transient Storage.
It is possible that something resembling this might appear in either Solidity 0.9.0 or Solidity 1.0.0:
uint transient x;
7. Reentrancy Guard Integration
Prior to version 0.8.0, the SafeMath library was a common tool among developers for arithmetic operations to avert overflow and underflow issues. With the release of Solidity 0.8.0, these safety checks were embedded directly into the language.
Similarly, Solidity versions 0.9.0 or 1.0.0 are expected to integrate a native Reentrancy Guard. This feature aims to streamline the process of implementing security protocols to protect against reentrancy attacks.
You may see something like this:
function myReentrantFunction(uint x, uint y) external reentrant returns (uint)
8. Restructuring Inheritance and Storage Layout
In Solidity, inheritance enables the creation of a new contract that adopts properties and functionalities from an existing one. The planned updates aim to refine the linearization of inheritance and the storage layout, thereby enhancing the predictability and organization of contract architectures. This could result in more efficient storage usage and less confusion in scenarios involving multiple inherited contracts.
For instance, a ‘Child’ contract inheriting from ‘ParentA’ and ‘ParentB’ may have an optimized storage layout with contiguous variable storage, reducing storage operation costs.
9. Enhanced Compiler Flags and Configuration Options
Solidity’s development includes expanding the range of compiler flags and configuration settings, providing developers with heightened control over the compilation process. These enhancements could lead to more tailored contract deployments, with refined control over aspects like gas optimization, security checks, and debugging capabilities.
New compiler flags could allow developers to toggle specific optimizations or security checks:
For example, a new compiler flag such as
--enable-loop-optimization
might focus on optimizing loops for gas efficiency, while another like--strict-security-checks
could introduce rigorous security analyses during compilation.
10. Improved Debugging Tools and Error Messages
Enhanced debugging tools with more informative error messages can significantly ease the development process, especially for complex contract structures. Improved error messages can provide a more explicit understanding of issues within the code, while advanced debugging tools can help developers discover and fix problems more efficiently.
11. Support for Advanced Data Types and Structures
Introducing complex data types and structures in Solidity can open up new contract design and functionality possibilities. This could involve support for more complex numerical types, enhanced data structures, or improved ways of handling large data sets within contracts.
Solidity might introduce a new data structure like
TreeMap
, which organizes data in a sorted manner, allowing for efficient retrieval. This could be useful in contracts where data needs to be sorted or ranked, like in a voting system. Another advancement could be the support for more complex numerical types, like fixed-point numbers, enabling precise mathematical operations directly in the contract.
12. Introduction of Generics and Templates
Generics and templates in Solidity allow for more adaptable and reusable code. For instance, a generic function could be created to handle different types of assets (like ERC20 tokens, NFTs, etc.) in a standardized way without needing to rewrite the function for each specific asset type. This will enhance contract design patterns and development efficiency, as a single function could be applied to various scenarios.
contract AssetHandler<T> {
T asset;
function processAsset(T _asset) public {
// Generic processing logic for various asset types
}
}
Future Perspectives: The Road to Solidity 1.0.0
Across various online platforms, including GitHub, Twitter, Ethresearch, and Reddit. There is a lively discussion within the Solidity community about the roadmap beyond version 0.9.0.
A central debate is unfolding:
Is it more prudent to directly transition to the landmark Solidity 1.0.0, marking the language’s full maturity, or should there be a gradual progression through version 0.9.0 first?
The anticipated debut of Solidity 1.0.0, shaped by community feedback and creative ideas, might align with significant Ethereum updates, mirroring the growth and stabilization of the entire ecosystem.
- Evolution of Type System: Elevating Flexibility and Security An upgraded type system is expected, drawing inspiration from functional programming languages like Haskell or Scala. This evolution aims to enhance the safety and flexibility of contract development.
