Contributing to Solidity 101

The Solidity programming language is an open-source project governed by a core team. We rely on the community’s feedback, input and contributions to make the language as effective, safe and useful as possible. In this post, we will walk you through the various different ways how you can get involved contributing to Solidity! Do not hesitate to contact us in case anything is left unclear after reading the post. [Read More]

An Introduction to Solidity's Fuzz Testing Approach

Security vulnerabilities and bugs detract from software quality. To discover them early, at best before they are released, we have adopted fuzz testing: feeding randomly generated programs to the Solidity compiler and observing the compilation runtime and code generated. Since Q1 2019, the Solidity compiler is fuzz tested via Google’s open-source software fuzz (oss-fuzz) framework. In this post, we briefly describe the work that has been done on this front, and work that is currently in progress. [Read More]

Launching the Solidity Forum 🗃️

In our effort to foster exchange of information, encourage more developers to give feedback about Solidity and join the discussions on language design and future direction of the compiler, we are happy to launch the Solidity forum today!

Launching the Solidity Developer Survey 2020

Today we are launching the Solidity Developer Survey 2020. It is the first time we share a proper language survey and we hope to turn this into an annual tradition moving forward. You might remember the small feedback survey we did this year as part of the Solidity Summit registration in which we asked you for the most liked and dreaded Solidity features. If you’re curious to revisit the results of that click here. [Read More]
