 I'm Marfonso Larrosa, I'm a research engineer at Portable Labs, and at Consoles Lab, what we're working on mainly and what we're focusing on is on IPC, and the idea behind IPC, many of you may be aware already, is to scale horizontally the Filecoin blockchain. So try to run subnets that are able to interpret with the Filecoin Mainnet and interact and anchor their security to them as a way of deploying new applications that can have more scalability and new features. Last year, we were focused on figuring out how we could do this, have an MVP, and this is how it looked like. So we had Lotus, everything was a monolith, and running a subnet, it was as easy as calling a command in Lotus, and it would run the subnet for you, and you could start interacting with it. It was great, because the user experience was great, but it had a lot of problems in terms of once you want to move into production, because if a subnet failed, it was really hard to, like, everything was handled with routines, and then it was a nightmare. So as we were moving into production, this is what the architecture looks like, and what I'm going to show today, actually, I think I demoed it six months ago, right, months ago, but it was with this architecture. Now we're moving into the production architecture, and I'm going to show how it will look like as we move into Mainnet. And the idea is that we have a new piece of software. Instead of having everything in the same Lotus, and like handling everything in the same Lotus, what we have now is that we have the different independent networks and subnets, so this rootnet could be the file called Mainnet, and we could have running, or like the community could run different subnets, and we have this piece of software that is called the IPC agent, which is the one that is going to orchestrate all of the communication with a different blockchain. So instead of having to run a single Lotus that has to know how to interact with every blockchain, which has a limitation because once we start having like other technologies in these subnets, it's really hard to embed every consensus algorithm and every single feature into Lotus. So in this way, we're decoupling what we call replica. So the running of the blockchains from the subnets from the IPC agents, which is our IPC client and the one that we use to use IPC over all of these networks. And so if someone wants to run a subnet in IPC that is communicating with FileCon Mainnet, it wants to communicate with some L2 and it wants to run another L3, this is the architecture or the different processes that it would have to run. So the IPC agent communicating two different nodes or peer implementations in each of these networks. So you see that this allows to more like more decoupled architecture, but before we were all happy and young and it was just interacting with a single process. Now we have a lot of processes. There's a lot of overhead that we need to handle. If you want to look at the code before, it was all Lotus. Everything was in our fork of Lotus that we called Iudico. Now there are a bunch of other repos because we have the APC agent that is this client that I'm going to show that it's used to orchestrate the different instances of subnets with which our applications wants to interact. Then we have the IPC actors because with FVM before everything was in the legacy VM of Lotus. Now we target the FVM. Actually, we are not targeting the FVM. Everything is in Rust, but we're moving into Solidity this contract so that we can also be in user land with FVM. But right now what we're doing is we have a custom bundle in our subnets that include our FVM actors compiled to WESM. If you want to have a look at the actors that run all of the on-chain logic for IPC, you can go to this repo. Finally, we have, of course, Iudico, which is our fork of Lotus that includes a new consensus algorithm and does all of the heavy lifting of the blockchain side of things to run each of these different subnets. It's the peer implementation for each of these subnets. As I was saying, there's a lot more now than before. Before using IPC or CC, now we're trying to improve the UX, but we are working on a lot of documentation, and it would be great if all of you can start testing this and give feedback. DVD is perfect that you did that demo because we really need to do dog food this and figure out the right UX for this tech. With that, I will jump into my demo. As I was saying, our main process for contract with IPC is the IPC agent. What I'm going to do first is run this IPC agent. Now we're running the IPC agent. It's a really slim process that will do all the interaction with the different blockchains. What we need to do now is we have nothing right now. IPC is not there, so we need to run some rootnet and from there deploy a subnet. The first thing that we're going to do is we have this convenient script to run a rootnet. This is a script that runs a single validator rootnet is for testing, and it simulates what would be our interaction with the Falcon mainnet if we wanted to deploy a subnet over Falcon. This may take a while because under the hood, what this is doing is deploying a Docker container, creating a lot of Zemon, and then running a mere validator because we're simulating here actually not the Falcon mainnet, but our SpaceNet testnet that runs the mere consensus. The mere consensus, in the end, is a BFT consensus that goes a bit faster, so our subnets ship with these consensus that is faster and has like you can go at any block time that you want, but we have it configured to go at one second block time, so deploying an actual deploy as my contract should feel faster than how it feels now in Falcon mainnet. Yeah, I should have prepared some joke or something for the wait. In the meantime, let me share the other piece that, oh, okay, cool, so it was what's unexpected. So here you see that we deployed the rootnet and it gives us this script a bunch of information that we need for our IPC agent to be able to interact with our, in this case, we only have a node in the rootnet, but we could have like a single node running like interacting with the Falcon mainnet or whatever other architecture we want. So here it says that we're running in this container, that's not important, but it will be really important is what is our default wallet and what is the token to interact with our peer implementation in the root. And the reason for this is because we have to go to our IPC agent and tell them to what are the credentials to interact with the rootnet. In this case, I'm just going to interact with the rootnet, it's listening in this board and I'm gonna give, I'm gonna give him the, so with this, our IPC agents now know how to interact with the rootnet and we can create a new subnet. When we say this IPC agent creates subnet, actually what we're doing is deploying what we call the subnet actor, which is the smart contract in the rootnet that will govern the operation of the subnet. So, hey, hello, something fit? Okay, BC is probably which I didn't copy pasted this correctly. Okay, so I forgot to reload the coffee. Notify with my next, what was my latest? So sorry. Yeah, so now I'm gonna be able to create, should have done a cheat sheet for this. So yeah, once I get the token, I have to put it in my, in my config and reload the config. So now you see that we created this subnet actor that is gonna govern the new subnet and it says that we have a subnet run, like a new subnet actor where we can run a subnet with ID root t0 1 0 0 2. So now what we're gonna do is actually run a node for that subnet. So join the subnet and run in that subnet. And I mean, we have also this convenient script to show how it works, but in order for you to see the logs and see what is happening under the hood, I'm gonna run the node manually to show you how it works. So here I'm just running a lot of Zemon with the genesis of this new subnet. And what we're going to do now is initialize the validator for the subnet. So we initialize the validator for the subnet, we import our wallet. And you'll see that right now if I try to run the validator, so actually, yeah, I try to run the validator, it's gonna fail. And the reason for this is that because I haven't joined the subnet. So my node will interact with the parent and we'll have to ask permission to this subnet actually that we just deployed to ask for permission to, because like the parent is the one that runs the subnet. So what we need to do is to join the subnet in the parent. To do that, like we have to check, I mean, we have to announce what is our validator address. We take like any of these multi addresses for my validator. And now we're gonna join the subnet. So from the APC agents, we say that we wanna join these new subnets, that we wanna put this amount of file length as collateral. And we wanna be, we want all the validators to find out in this. So we copy there. And once we've joined the subnet, what we're gonna be able is that now the parent will have us registered as a valid validator of the subnet. And you see that when we try to start running in these gates, now we're part of the subnet and we have the rootnet where we're mining. And also we have a new network here, subnet where we could be running any kind of application. What happens if like, again, with the APC agents, we can handle all the life cycle of our subnet. We could deploy another subnet. For instance, we could create here a new another subnet with the parent in the root. And we'll have some other, so the ID was in this case, C01, C02 and I could run my own application on my own nodes for this. But the subnet, and I can also leave the subnet. And if I leave the subnet, what happens is that I take out my stake in the subnet. So here in the bottom right where I'm mining, once I leave the subnet, these validators should crash because I no longer have rights to mine in that subnet. So I leave the subnet, and once these transactions go through and the stake goes down, these validators should crash. And you see like it crashes because I no longer have access rights to mine. So this is just the life cycle of a subnet. Sorry for the delay, I forgot completely about reloading the config. We also have convenience. So I showed you how to run a node for the subnet manually, but we are also working on scripts to run, but that's gonna take a long time. So probably won't do that, but like we can run these subnets in a docker and you specify like the subnet that you wanna, you wanna, the node for the subnet that you wanna deploy and so on, and you're able to have containerized all of these processes that have been running locally. And the idea is that we're trying to figure out like the right UX. So as, I mean, once it's ready, we will really appreciate all the feedback that you can give us to make these, like deploying subnets as soon as possible. Thank you.
