Announcing Solidity Version Collectibles & Community Governance 💎

⚠️ Attention: This post is an April Fools’ Day joke. Please consume it at your own risk. We will not distribute any Solidity NFTs in the foreseeable future. Stay safe. Today, we are excited to announce a little surprise we’ve been working on silently for the last couple of weeks. We heard that you really like crypto-related collectibles and we listened. You will soon be able to own a digital piece of Solidity’s history: We’re tokenizing each Solidity version as... [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! Moving forward the Solidity forum will be the dedicated place to discuss topics and questions related to… The design of the Solidity programming language. The Solidity compiler. Useful Solidity tips and code snippets. Solidity documentation and its translation. Discussions and announcements about... [Read More]

Solidity Developer Survey 2020 Results

Before we dive into the results we want to extend a big thank you to all of the Solidity developers that participated in the very first Solidity Developer Survey, which we conducted at the end of last year! We were overwhelmed by the high quality of the submissions and are happy to extract important insights from your input. In this post, we’ll be summarizing and commenting on the results of the survey. Please note that none of the questions in... [Read More]

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]

Announcing the Winners of the Solidity Underhanded Contest 👨‍💻🏅

After thorough assessment of all submissions, we are happy to share the winners of this year’s Solidity Underhanded Contest! Before we dive into the winning submissions, we’d like to thank all participants for taking part. In total, we received 16 qualifying submissions which you can find in this repo. All 16 submissions are eligible for a “qualified submission” Solidity Underhanded POAP NFT - winners will receive an additional “Winners” POAP NFT. We will be in touch with all participants shortly... [Read More]

Ask the Solidity Team Anything #1 Recap

We hosted our very first Solidity team AMA on Reddit last week! We would like to take the opportunity to summarize the most interesting and most upvoted questions & answers in this post. If you are interested in going through the full AMA thread you can do so here. [Read More]

The Solidity Underhanded Contest is back!

We’re excited to share that the Solidity Underhanded Contest is finally back! Inspired by the Underhanded C Contest and the first Underhanded Solidity Contest, organized in 2017 by Nick Johnson, we decided it is time for a much needed revival. The goal of this contest is to write innocent-looking Solidity code, which pretends to be clear and straightforward, but actually contains malicious behavior or backdoors. By hosting such a contest we aim to: Raise awareness about smart contract security. Uncover... [Read More]

Meet the Solidity team! 🧑‍💻👩‍💻

As you might know, Solidity is an open-source community project mainly developed and maintained by a core team. Today, we would like to introduce some of our team members and share insights into their professional background, which components of Solidity they mostly work on, what they would like to see in Solidity and in the ecosystem in future and more! Since almost all of our work happens on Github you can find each team member’s Github handle next to their... [Read More]

Solidity v0.1.0 turns 5! A walk down memory lane...

With happiness and a tad of nostalgia, we’d like to share that Solidity v0.1.0 turns 5 years old today! (To be fair, v0.1.0 wasn’t an actual release, but it marks the time where the Solidity team started appointing version numbers.) We are puzzled over how fast time flew by. We’d like to use this opportunity to take a look back and walk down the Solidity memory lane together with you. In short: The Solidity language evolved rapidly, the ecosystem went... [Read More]

Wrapping up the Virtual Solidity Summit 2020

Roughly one month ago, we held the first Solidity Summit - a free interactive forum with discussions and talks on Solidity, Yul, language design and tooling. It took place on April 29-30 and was powered by a virtual meeting infrastructure based on open-source, self-hosted Jitsi video chat rooms. The platform was supplied by Interspace.Chat. Before we dive into the recap: Your input and active participation was much appreciated and we want to take this opportunity to say thank you! We... [Read More]

Sourcify: Towards Safer Contract Interaction for Humans

tl;dr: Building sensible blockchain applications for humans is hard. You can enhance the user experience of your dapp today by leveraging the power of open source. Increase awareness and give more transparency on what users are actually doing when interacting with your code on the blockchain, i.e. when signing a transaction, by publishing the source code to this decentralized repository and using metadata files, which translate “random” hex strings into human-readable language. Sourcify is a tool to help you do... [Read More]

Solidity Summit 2020 Goes Interspace

Tl;dr: As already announced on Twitter, we transformed the Solidity Summit, which was initially planned to be an in-person meeting in Berlin, into an online event. Today, we are excited to share that the summit will be powered by Interspace.Chat. Interspace is a virtual meeting infrastructure based on self-hosted Jitsi video chat rooms. Check out the Solidity Summit’s preliminary event agenda here and make sure to register if you want to partipate! [Read More]

Dev Update: Formal Methods

This post was originally published on the Ethereum blog. Today, I am delighted to announce that Yoichi Hirai (@pirapira on github) is joining the Ethereum project as a formal verification engineer. He holds a PhD from the University of Tokyo on the topic of formalizing communicating parallel processes and created formal verification tools for Ethereum in his spare time. In his own words: I’m joining Ethereum as a formal verification engineer. My reasoning: formal verification makes sense as a profession... [Read More]
