Hardhat 3 Preview: Overhauled & Rust-Powered

 Hey everyone, thanks for being here. My name is Patricio, I'm the co-founder and CTO of Nomic Foundation, which is a non-profit dedicated to Ethereum developers like you. At Nomic, what we do is building open source infrastructure and tooling for the Ethereum community. And the most well-known of our tools is HardHat. And during this presentation, what we are or I'm going to talk about is HardHat v3 or HardHat 3, the new version of HardHat, which is still in development because it's a whole overhaul of HardHat v3, or HardHat 3, the new version of HardHat, which is still in development, because it's a whole overhaul of HardHat with tons of changes. But first, let's take a look at HardHat 2 for a second, especially its limitations and why we decided to rewrite it. The first one, and main one, is that Ethereum changed a ton during the lifetime of Hard Hat. We started working on it almost seven years ago, about 2018. And back then, Ethereum was a single chain, a way more simple ecosystem. There was mainnet and a few testnets. Those testnets aren't even alive nowadays. And the applications were simpler, those test nets aren't even alive nowadays, and the applications were simpler, right? There wasn't even stable coins back then. Now, applications are larger, and Ethereum turned to be a single chain into an ever-increasing ecosystem of different chains, each of them with a slightly different behavior. Another problem that we have in Hard Hat 2, or Hat, is that we brought everything in JavaScript, including our network simulator, and that had several performance issues. We also focused a ton on the Node.js ecosystem because we envisioned building a platform for others to be able to customize and extend their own setups, but that focus on JavaScript only also meant that you could only write tests in JavaScript or TypeScript. And the final limitation is that when we designed Hard Hat, there was only one chain mainnet. We designed it in a way where for every single hard hat process, there is a single chain, a single network connection, you just import hard hat, you have your network connected there, most of the time it's going to be simulated by us, and all the boilerplate, all of your libraries, all your plugins get configured for you, but it's a single chain. As soon as you want to work with multiple chains, you hit this limitation and you start making workarounds. We created RPCs for switching the hard forks or forking other networks. People use different configurations and things like that. So, HARDCAD 3, we rewrote it from scratch to circumvent these limitations and offer more functionality. And how does it look? Well, it looks a bit like this. It's a bit like hard hat. It's still hard hat, but hard hat from the future or more technical hard hat. But at the end, it's just a hard hat, right? Like, it feels and looks like hard hat. So, as I mentioned, it's a complete revamp of the product. The scope is massive. Hard hat grew during these six, seven years. It has tons and tons of clients and functionality. And I can't cover everything here. I'm only going to focus on this list of things, which are the network simulator that we rewrote in Rust, the Solidity Test support that is added in hard hat 3, our deployment solutions.

Keynote: Nomic Foundation’s vision for Ethereum’s tooling ecosystem

 Leonardo Silva Reviewer:" Elisabeth Buffard ...region in Latin America. So, two years ago, we had DEFCON 6 in Bogota. It was an event that brought thousands of minds to the city to get together and start improving the ways that we did things before DEF CON. So in DEF CON, it was a fantastic gathering in one venue, a big venue that we had in the city there in Bogota. It was a place where we were able to meet in between and start working together. A lot of things started at that moment in the whole region with leaders from every country of the region. And it sparkled, it started something that was starting joining together more community in the different cities of the region and having community events that brought a lot of people inside the different countries. There were a lot of new steps on how to bring blockchain education to the region through different methods all over the place, all over the different countries, starting using new programs to involve developers in the Ethereum ecosystem. And it started growing through alliances with universities and networks of universities. This was something that wasn't happening a lot before the DEF CON, but afterwards it started to pop up in different places all over the region, and it happened more to hackathons and these alliances with universities. And it just came all over the place. So right now, between all the different communities around Ethereum in the region, we have onboarded over 2,000 developers, mainly Web2 developers into the Web3 ecosystem and the Ethereum ecosystem itself to different programs and it's people who before DEF CON they had no idea of what was going on in the industry, but now we have this new sense of consciousness of what are the possibilities and mainly taking the message to the people in the region that it's not an industry only to be a user, but you can be a builder. And it's something that it's been made to attending three main points, that is community, education, and development. Two, community, education, and development. Two, alliances, events, and production. And it is growing and growing. There's more and more alliances happening all over the Latin region, between the communities and universities, all the different communities, and universities, all the different communities, social places, and in general, the actors of the ecosystem, like putting everything together to make things happen. And right now, there has been great improvement in the ways to do and to bring the education to the people through online programs and putting together developers and students from all the region together, developers and non-developers who are starting to build in this program. Have we had some impact? I'm just going to mention a few cases of the students that we have had that, I don't know, 18 months ago they had no idea about the industry, and now there's the case of Neil, who at 17 became a Deaf Connect 2023 scholar, and he was able to travel to Turkey and share his experience as a new developer with developers from all over the world and also after this time Christian and Juan Diego who are here today they after taking this these courses and joining to these processes and giving time to it they have been able to find jobs in the web3 industry and go to... They used to work at a call center before that, and now they are part of the industry, and they were able to travel here to DEF CON. So what needs to go next? We need regional coordination. We need to nurture an environment of trust between community builders and community users, so we can take all these to the next steps after the education and create spaces in common between the different actors of the whole region. So we need to push to encourage frequent blockchain interaction within the different actors of the whole region. So we need to push to encourage frequent blockchain interaction within the different communities and find places where we can share hackathons, opportunities to work open source and bring this to a next level. Before the end, I just want to mention between into this great impact that has been in the region there's have been also very difficult times he was Emerson David Silva he was part of the Ethiopian Colombia leadership and he was assassinated by the war this terrible war we have in Colombia so we lost him this year in March 27 and I asked myself why can't I do Emerson to preserve and honor your legacy he's present every day in my thoughts and the community and the leadership dots we want to make his legacy to go further so we have we need to support Emerson's family so if if you scan this QR code we have, we need to support Emerson's family. So if you scan this QR code, we have a Givet project. So we are trying to get funds to help his family and to keep on helping on the operations on education in Colombia and Arauca. So thank you very much. It's been a pleasure. And thank you very much. It's been a pleasure, and thank you. Thank you. We're going to do one quick question of Q&A. You mentioned you onboarded 2,000 developers to the ecosystem. How did you estimate this number? This number is estimated between data that we have from the different organizational processes that has been taken into the region. So we have more than 15 organizations onboarding new developers. So this number comes from what has been done in the last 18 months. And what do you think are the best next steps for the students that just learned about Ethereum? The next step is the most important thing because we need them to take what they learn to the different educational processes and apply that into hackathons, working in open source, working together, meeting other people. And this is something that we are pushing right now. Thank you very much. Thank you. That concludes the session, everyone, on the ripple effect of DevCon.
