 Awesome. Hi, everybody. Can everybody hear me? Great. So, first of all, how many people here are familiar with Hyperledger Beisu? Some, most everybody? Great. How many people have used Hyperledger Beisu? Awesome. So, we have a pretty Beisu familiar crowd, and that's fantastic. So, today I'm just going to give a brief overview of what's going on in Beisu and some things that we're excited about. So, if you don't know what Beisu is, Beisu is an enterprise grade, Ethereum execution client designed to work on both mainnet and in permissioned Ethereum settings. So, I have a picture of Janus, if you know who that is, the ancient Roman god, looking back on the new year and the old year, and sort of Beisu looks at both mainnet and permissioned Ethereum. So, many people are sort of under the misconception that, you know, Hyperledger is only about, you know, permissioned blockchain and it has nothing to do with Ethereum. But it turns out there's a long history of Ethereum and Hyperledger working together and having a lot in common. So, do people remember Burrow? Some people, yeah. So, Burrow is sort of the first explicit Ethereum project in Hyperledger. But Hyperledger and Ethereum have worked together and been involved together for quite some time at this point. So, more about what I said about the execution client. So, with the merge, Ethereum is transitioning to a modular blockchain design with consensus clients and execution clients. So, if you're familiar with blockchain architecture, you know that you have, you know, a consensus component of your blockchain and a smart contract execution component of your blockchain. And Ethereum is separating these two out into a modular protocols. Are people familiar with this in general? Awesome. So, you know, maybe you've seen some of the consensus clients and of course the execution clients, Beisu is one of them. So, one thing to note is if we look at the popularity of these clients, right? So, you can see the consensus clients, you know, Prism and Lighthouse are popular. But for the execution clients, Geth has almost an 80% market share. So, we see Beisu has, you know, about a 7% share on mainnet right now, which is great, but we would like that to be larger. And the problem with this is the client diversity website points out is that if there's a bad bug in Geth, it could bring down the whole mainnet. And due to the slashing mechanism, when the network came back up, when the bug was fixed, there would be lots and lots and lots of youth slashed, which would just be a disaster for the network. So, the Ethereum Foundation to sort of address this problem of client diversity started a grant program for clients and Beisu was chosen as one of the clients. And most grants, you know, you all are probably familiar with how grants work. You know, people give you money to do something. And most grants in this space were pretty straightforward because single companies or organizations were responsible for client development. These projects in general may be open source, where the code base is open source, but they're not true open development where anyone can join, anyone can contribute, and anyone can attain a leadership role like Hyperledger or Linux Foundation projects. So, the Beisu execution client incentive program is written for a true open development project. We had to spend a lot of work on this, but the summary is that anyone who shows a sustained pattern over time of important contributions to Beisu features that benefit mainnet can get rewarded with grant money. So, you know, if you want to contribute to Beisu in the long run, you can participate in this program, and we have everything online and you can read all the details and exactly what this takes. So, you know, rather than hear all of this in more detail for me, you know, we thought we would have Tim Baiko, who manages the core devs group at Ethereum, tell you about this. Unfortunately, he couldn't make it today because, well, if you all are familiar, the merge is happening very soon and Ethereum is all hands on deck for that. So, no one is traveling. But Tim very nicely agreed to tell us some of his thoughts on Beisu. So, we'll go ahead and hear from him. Hi, everyone. My name is Tim Baiko. I coordinate the all core devs call, which is, which are the calls where all the client teams working on the Ethereum protocol get together to discuss and implement changes to the protocol. And I wanted to take a few minutes today to talk about Beisu, the merge and this client incentive program. Unfortunately, I couldn't make it in person. As you're all probably aware, the merge is happening this week, so I couldn't travel during this week. But yeah, hopefully take a few minutes to walk through Beisu its own ecosystem and how we've kind of structured the incentive program to support it. I actually, before working on coordination across all the clients, was working on the Beisu team, once was a Beisu maintainer. And I think Beisu helped kind of make Ethereum accessible to a large number of users who maybe weren't as in touch with the Ethereum mainnet through its large enterprise program. And at the same time did this without compromising on supporting the Ethereum network. So from the very start, Beisu was kind of designed to be an enterprise grade clients that would support mainnet and that would keep kind of pushing and innovating there. And it's been really great to see what, you know, what the client has done over the years. Starting from being only owned by consensus and kind of a very bare bones client that could sync mainnet and archive mode and offer some enterprise features to now being kind of a thriving project within the hyperledger ecosystem to have helped led some of the most important and impactful changes to Ethereum such as EIP 1559 and having also like a set of maintainers that spans multiple organizations. So, you know, I think Beisu is really a great example that you can have people with very different backgrounds coming in contributing to the same code base and making this kind of a better product all while kind of staying aligned with the general vision of openness that Ethereum believes in. And, you know, to take a minute to talk about the incentive program, basically the Ethereum foundation has wanted to kind of provide an incentive package so that teams and individuals working on these clients feel like they can share upside in Ethereum if they keep maintaining this and keeping the network running. So, I think this was first in 2020 there was an incentive kind put together for the teams working on the beacon chain and in 2021 we decided to extend this to all of the client teams so including Beisu and the other teams working on the current proof of work or execution layer chain. And for every team it was quite straightforward because there's only a single organization that kind of owns the client so we could simply put all the grants to them and kind of run with that. But with Beisu it took a bit more work but I think I'm pretty happy with the structure we've arrived at where today, you know, we have a structure with Beisu's incentive program where there are many organizations who will receive the funds from Consensus, the Hyperledger and others and there's a path for people to come and be kind of contributors to Beisu then become maintainers and eventually also receive rewards as part of this program. So that's really something that's important to me and why I think it was worth spending the past six to nine months tweaking the program to make it work right for Beisu and I'm quite happy with what we've got. So, the program is live, it's running all the validators have been set up we have kind of the smart contracts set up to split the funds across the different ecosystem participants and yeah, to me this is really a very cool example of what we can do by, you know, having these innovative programs on Ethereum and kind of adapting them to communities and open source projects that work in a very open way across multiple organizations. So yeah, thank you again for the opportunity to speak here. I'm sorry I couldn't do it in person directly but I hope to see you all at DEF CON in just a couple weeks. Cheers. All right, thank you very much and you know, the most important thing about a conference is not necessarily the talks it's meeting people and knowing people so when you have a question you know who to talk to so for that reason I'd like to introduce some of the Ethereum maintainers I'm sorry, the Beisu maintainers so if you all could stand up please if you're there so wave to everybody so I think we have Diego, Dano, Francisco and Matt so if you're interested in Beisu please come find these folks they are wonderful and they will answer all your questions so thank you very much
