Superchain Explainer - Karl Floersch | Superhack Summit

foreign [Music] talking about super chain 101 so without further Ado please welcome Carl here with me to uh tell you all about soup chains hey Carlos hello how's it going it's going great we'll uh we'll let you get started welcome alrighty wow I apologize for the semi-salse advertising because this is definitely not a 101 this is more like a uh significantly more um very very in-depth if you want a real one oh uh the Devcon talk is probably the way to go but you know what we are all about getting into the weeds also notably notably some of you might have seen some of this presentation before um because it is on the um but I think it'll be a good refresh there's way too much information here um so it's it's a good one but yes this has to be a boring presentation because it's very in the weeds let's go let's do this time's up okay so super chain to the rescue Ramen why are we building the speaker chain well it's to scale because blockchains are so insufficient for the decentralized weapon we want to create why is that well because of congestion oh my God so blockchains don't scale right like we are often paying 15 and you know 13 for a transaction it's insane my transaction was just an electric Electronic Arts trying to tweak now not tweet I'm trying to act um and it paid 13 for that transaction no way no way no way so we need scalable infrastructure that is decentralized can still support the insane amount of traffic interput that we you know require and so this isn't new right like this has been a problem from day one first response to the Bitcoin white paper we very very much need the system but the system that you proposed does not seem to scale sorry Satoshi um we have to make progress on top of it so anyway this has been plaguing the industry since 2008 it's now 2023 goodness gracious let's do this so okay before we like you know and and cried let's imagine a future because we are very close to that future we are incredibly close what if things were different it wasn't just crypto wasn't just about you know me and clients and you know it was also and everyone was using it for literally everything all like you know from social media to games to Etc and the whole world was running on decentralized well you know what would that be like right we can literally abstract away the back end software stick we don't have to worry about what provider we're using because we're using a decentralized network of providers that are all competing on the same internet standards it's like standards for the entire internet's back end and additionally usually had we would so much more composability people can actually work together application developers can work together the boundaries start to dissolve between one application or the other and we don't need to worry as much we can think more about the applications that we're building and not so much just about the infrastructure I mean let alone all of the amazing open source software that we would then be using and this is how we clearly you know the the internet from a Walled Garden you know difficult to hack on and contribute to your ecosystem to a vibrant vibrant world and so obviously of course in reality these pictures were going the other direction stopped using sunblock that's our sponsor um okay anyway no we should we have to oh my gosh I literally need to do these slides into Twitter you can build in this world right like you should be able to build the application Logic for Twitter that is horizontally scalable as a smart contract in a hackathon weekend that's where we need to be okay so the decentralized win obviously still can be realized we've been working on it for years started out building out east 2.0 like we were trying to Shard ethereum directly then we realized that we needed to build it out in Layer Two which we you know formed plasma group to scale ethereum and that way and then we realized that not only is there a scalability problem but for optimism we realize there's a public goods funding problem AKA there's no way to build open source software and get get rewarded for it so that's that's kind of the transition from plasma group to optimism so anyway but it's not just been us it's not just been us building out this Tech it has been a massive web 3 ecosystem full of developers and tons of incredible contributions talking about Roll-Ups the role of centric ethereum road map and it has allowed us to over time to find the instruction layers that allow us to scale this software together right in order to really unlock the internet stack we needed to define the stack of software that all works together the transport layer you know Etc that all works together to serve the internet we're doing this same thing this time for the decentralized web for the base essentially the stateful decentralized web first you know web one was kind of stateless so all of these different contributions they've led us to L2 they've let you know shout out to Barry Lynnette um we are starting to see the architecture clear and clearer and so that's really what this talk is about it's trying to give you the intuitions around what are the different layers of this stack and how do they all fit together and how all of that comes together to tactical congestion with the super chain let's super hack pal one two three okay okay so what is the super chain curse the basics right scaling to score the internet why is that well because a chain you need to be able to sync the chain download all the transactions replicate it on your local machine that is a critical property of chain software but if we were to just increase the size of a chain arbitrarily well what happens the blacks get bigger and bigger until my computer explodes and forms the black hole because there's too much information in one place we need to horizontally scale it's a fundamental law of nature um but it's not multi-chain right the super chain is not quite um you know the Loyalty chain future because multi-chains are insufficient they each different chain has its own different responsible own different validator sets so each one has security so as you bridge from chain a to chain B to chain C that is actually a different asset that you fundamentally created versus bridging from chain a
