[00:07.400]Hello, thank you to the Monero Village organizers and the Monero community for inviting us [00:13.300] [00:13.300]to be part of this amazing conference and the opportunity to show you what we are doing at [00:18.600] [00:18.600]LochaMesh. We are going to show you a demo of the LochaMesh, which is a community-driven, [00:25.140] [00:25.140]open-source software and hardware project. It started two years ago with the idea of making [00:30.600] [00:30.780]a decentralized censorship-resistant network for payments and communication without internet. [00:35.400] [00:35.400]For disaster-hit countries and privacy-concerned individuals and groups who would like to keep [00:41.060] [00:41.060]their privacy and their communications and payments as private as possible. [00:46.960] [00:47.480]Well, Mesh Networks has existed for decades now, but we focus our efforts on making one [00:54.480] [00:54.480]that doesn't rely on seed nodes or bootstrap nodes or servers nor intermediaries at all. [01:03.340] [01:03.340]Each LochaMesh node is independent and can keep enough information for it to be able to [01:09.480] [01:10.140]deliver messages through PATH and HOPS to its destination messages and data without internet [01:16.820] [01:16.820]at all. Well, Luis, who is the CTO, will show you a demo of a Monero transaction that is going to [01:26.340] [01:26.340]take place from a completely off-the-grid computer that is only connected to the LochaMesh network [01:31.720] [01:31.720]to a remote Monero node. Luis? [01:37.960] [01:38.980]Good afternoon and welcome everyone. I would like to start by thanking all [01:45.760] [01:47.380]of the Monero community and especially to those who supported us through Monero CCS [01:56.720] [01:56.720]proposals. I'm Luis, the CTO and co-founder of LochaMesh. I would like to show you a demo [02:04.860] [02:04.860]running the Monero graphical user interface and the Monero daemon in the same network, [02:11.460] [02:11.460]in this case in the LochaMesh network. As you can see in the picture, here is the environment. [02:19.200] [02:19.800]On the right side, you can see the server [02:26.980] [02:29.860]with two network interfaces. One is connected to the internet and the other to LochaMesh. [02:39.620] [02:40.820]The Monero daemon is running on this server. The network interface for the LochaMesh [02:48.700] [02:49.800]is this one. And on the left side is my laptop represented as n1 using the launchpad. The [03:03.020] [03:03.020]launchpad is this red bar, as you can see in the webcam, and this red bar is the network interface [03:10.560] [03:10.560]for the LochaMesh using this address. Between them, we have a node whose network address we [03:24.400] [03:24.400]don't know, but we don't care either because it just helps to find the path between my laptop [03:31.360] [03:31.880]and the server. Shut off the other microphone. You have two of them, I think. [03:37.540] [03:38.800]Or is it... it is down, right? I don't know if it's... [03:42.520] [03:43.500]What? [03:44.520] [03:45.100]No, check the other microphone in case it is in the other computer. [03:49.240] [03:49.420]I don't know if it's working or not. [03:51.640] [03:51.680]It's noisy? Noisy? No, it's closer to the microphone in the other computer. [03:59.160] [03:59.160]Okay, okay, continue. Yeah, sorry. [04:01.600] [04:01.600]Sorry. [04:02.260] [04:03.370]Okay. [04:05.440] [04:07.930]What? [04:10.000] [04:13.900]Between the laptop and the Monero, there is a node, so we can start [04:24.730] [04:29.490]with the terminals. On the right window, [04:39.300] [04:40.260]I have an open terminal to the server running the Monero [04:44.000] [04:46.380]server, and I have configured the network interface for the LochaMesh. [04:53.460] [04:54.300]And we can check the interface. The interface is this one. [05:10.340] [05:10.940]And in the left side, I need to check. [05:15.660] [05:20.850]Okay, it's correct. [05:25.590] [05:25.870]Okay. [05:26.830] [05:28.530]Before executing the Monero GUI, or the Monero graphical user interface, we must [05:34.030] [05:34.030]make sure we have the configuration file ready with the server address. [05:40.110] [05:40.450]This is the Monero [05:42.010] [05:43.470]conf file. Okay, this is the address of the Monero server, and this is the port. [05:51.970] [05:52.870]So, we can [05:55.010] [05:57.490]start the GUI. [05:59.970] [06:07.290]Need to check [06:08.470] [06:10.910]the ways the wallet is synchronizing. This can take a while. [06:50.810] [06:55.280]And it's ready. [06:57.180] [06:58.720]So, the next step is Randy, can you send me some Monero, please? [07:07.440] [07:08.060]Sure. So, now that you have your wallet synchronized over the LochaMesh to a remote Monero [07:13.920] [07:13.920]GUI, he can now create an address to get payments without having to have any connection to the [07:24.560] [07:24.560]internet. He's only connected to the LochaMesh through the toolkit device. In this case, he's [07:31.020] [07:31.020]using a Launchpad, which is for development. But you can see one of the revisions of the [07:37.940] [07:37.940]hardware we are doing there also in the webcam. So, he's now going to share with me [07:47.560] [07:48.620]Monero address to get payment. So, what we're... exactly, copy and share. [08:05.490] [08:05.490]What we are going to see now is that I, myself, who are connected to the internet, [08:11.570] [08:11.790]I'm going to broadcast a transaction to the receiving address Luis has shared with me. [08:21.050] [08:22.250]And the Monero daemon, which Luis is running on server, connected to the internet and also to [08:29.990] [08:29.990]LochaMesh, will see the transaction that I'm making on the internet. I'm going to set this to [08:39.510] [08:41.030]a good number so you can see it. Okay. Send. Now, my transaction is being sent over the internet. [08:53.380] [08:53.380]It's done. Enter password. Okay. Sent. Now, what is going to happen is that the Monero d running [09:05.590] [09:05.590]on the daemon that Luis has connected to both the internet and the LochaMesh, which is a peer-to-peer [09:12.090] [09:12.090]mesh network, is going to see this transaction on the Monero mempool. And it knows that this [09:21.870] [09:21.870]transaction belongs to this user who is connected to the Monero d over the LochaMesh only. [09:28.570] [09:28.570]So, now when the transaction has been broadcasted to the internet and the Monero d running on the [09:36.630] [09:36.630]server sees it, it's going to populate this or share this information with the user. [09:45.390] [09:48.650]Transactions. Yeah, it's sent. Let's see. So... [10:06.480] [10:07.000]Well, you can see there. There, you can see in the background of the user interface [10:15.340] [10:15.340]that in the terminal, you can see that the interface is communicating with the Monero d [10:22.380] [10:22.380]over the LochaMesh only. And now it has received the incoming transaction to its wallet. [10:30.190] [10:31.140]And this information, he has received it over the LochaMesh. The LochaMesh is a mesh peer-to-peer [10:37.780] [10:37.780]decentralized mesh network that only needs another node in range. So, it needs to be in range in order [10:49.740] [10:49.740]to be able to be part of the same mesh. And when there are going to exist more mesh [10:56.740] [10:57.580]isolated in cities or distributed in different countries, what we will have is bridges or long [11:06.620] [11:07.500]range distant radio that will connect one mesh with another over the internet as a bridge or [11:14.940] [11:14.940]gateway or also with long range radio. So, we're going to connect cities with each other and we'll [11:22.540] [11:22.540]have this mesh networks not isolated anymore in each city, but interconnected to make a huge [11:29.960] [11:29.960]network of devices that are capable of delivering messages, data, and information like in this case [11:39.880] [11:41.340]all over the world. So, once everything is running inside the mesh and you won't need to go [11:46.800] [11:46.800]to the internet anymore because miners will be inside the LochaMesh, servers will be running [11:53.700] [11:53.700]inside the LochaMesh, and Monero remote nodes will also be there, wallets, everything will run there. [12:01.540] [12:01.540]You won't need to use the internet anymore. What is the advantage of this is that, as you can see, [12:07.200] [12:07.200]you can have a developer launchpad that you can build yourself in your house and you won't need [12:14.640] [12:14.640]to be identified or KYC by anyone in order to be able to use the LochaMesh. So, we are making [12:22.400] [12:23.020]a custom hardware and this is important for us because... well, this custom hardware that [12:29.400] [12:29.400]you can see there on the revision hardware that we have is the Terpial and it's made out of [12:36.860] [12:36.860]pieces and components that you can buy online today. So, you can make your do-it-yourself version [12:42.080] [12:42.080]of it with all the shell parts too. So, if you do this and you do it in your house and you build it [12:48.440] [12:48.440]yourself, you won't need to identify yourself or share your ID or scan your face with any [12:54.920] [12:54.920]service provider, ISPs, or government in order to be able to communicate and make use of applications [13:02.840] [13:03.920]in this LochaMesh network. So, it is important for us to make the custom hardware [13:10.940] [13:10.940]because that enables us to develop the firmwares from scratch in order to make them [13:19.420] [13:19.420]open source. So, in order to be able to make it public, available for everyone to use, so that you [13:25.600] [13:25.600]can build your own or buy the ones that we are going to sell, instead of using already existing [13:31.680] [13:31.680]equipment for radio communications, which currently most of them, or if not all of them, [13:39.420] [13:39.420]depend on closed source tools for flashing and proprietary firmwares. So, the two devices [13:45.440] [13:45.440]communicate with each other over radio in the ISM unlicensed bands, 915 MHz and 868 MHz. [13:56.840] [13:56.840]The routing protocol that we are building is based on AODV version 2, and we have two IPv6 [14:04.760] [14:04.760]support. So, any application software server, which currently is capable of working with IPv6 [14:11.880] [14:12.440]address in the IP protocol, can run on the LochaMesh without any extra work. So, Luis is going [14:21.220] [14:21.220]to show you, for example, SSH access, web servers, Monero block sync, not only the wallet itself, [14:29.020] [14:29.020]is going to work inside the LochaMesh. Messaging apps, remote nodes, you will be able to access [14:36.500] [14:37.000]your computer over the LochaMesh without having to use the internet. So, you won't expose your [14:42.100] [14:42.100]house IP address. You won't expose your phone IP address, which is connected to your identity. [14:48.580] [14:48.580]You will be able to use the LochaMesh to do all this. So, now, Luis is going to show you how [14:54.260] [14:54.900]you can run a web server in a computer and access this website from another computer [15:01.600] [15:01.600]over the LochaMesh, completely off the grid, without having to use the internet at all. [15:06.740] [15:08.080]Very basic web server. [15:11.900] [15:24.040]And I need to launch the browser. Here is the browser. [15:45.070] [15:50.340]Here is the address of the server and the port. [15:54.900] [15:54.900]Okay, that is it. So, this is an example of how you can run a web server in a computer, [16:09.570] [16:10.690]a server, or a Raspberry Pi in your house, and you can access to that service or that computer [16:17.890] [16:17.890]over SSH, web, HTTP, and you can synchronize your wallet. You can synchronize your [16:27.330] [16:28.150]your full node, even over the LochaMesh, in a peer-to-peer decentralized mesh network that is [16:34.430] [16:34.430]private and information transmitted, the data transmitted, can be encrypted because we are [16:40.890] [16:40.890]using the unlicensed ISM bands, which allows you to encrypt the information that you are sending. [16:49.490] [16:49.490]So, it's also private. That's why it is so important for us that the Monero community [16:55.530] [16:55.530]has decided, an individual has decided, to support us through the CCS support crowdfunding [17:05.950] [17:05.950]method that they have. And we understand that the Monero community is a privacy-focused community, [17:13.470] [17:13.470]and we are also, too. So, we are not only enabling people to use Bitcoin and Monero [17:19.750] [17:19.750]without internet, we are also letting people continue being in contact with their loved ones [17:26.670] [17:26.670]during disaster-hit countries, for example, or censorship, internet shutdown, and blockades, [17:35.630] [17:35.630]or infrastructure failures. So, this is more a project, a community-driven project, [17:43.690] [17:43.690]which is open source. And we invite you all in the community of makers, hackers, and everyone who [17:53.550] [17:53.550]likes the privacy and the freedom of using your money to join us on our GitHub, which is [18:04.670] [18:04.670]github.com. And we invite you to join us in the Lucha por la Locha Libre, which is the fight for [18:16.610] [18:16.610]the freedom of money. So, in this demo, we wanted to show you what we are working on. As I said, [18:24.970] [18:24.970]you can build the do-it-yourself version of the devices yourself, but we also are going to sell [18:32.170] [18:32.970]the 2PL devices, which is a battery-based mobile hotspot that is going to give you access over [18:41.990] [18:41.990]Wi-Fi. It is a hotspot which has a Wi-Fi AP access point that you can access with up to four [18:50.850] [18:51.450]mobile phones. And you can also connect it to a server, like in this example, through a USB cable. [18:58.670] [18:58.670]So, in a range, if you have enough density and there are enough devices around you, you will be [19:06.770] [19:06.770]able to chat and make payments and sync your full node over the Lucha Mesh. What we are also working [19:15.330] [19:15.330]on is on the radio model itself. So, the radio model that is going to be welded in the 2PL devices [19:24.910] [19:24.910]is going to be available in other formats. So, you can use a Raspberry Pi hat, for example, [19:31.550] [19:31.550]and add it to a Raspberry Pi. So, it is going to be able to communicate over the Lucha Mesh with [19:38.310] [19:38.310]others in order to offer services, for example, a web server or a wallet sync or an Electron server [19:45.110] [19:45.110]or a remote Monero D that others can use. And you will be able to get paid for that. So, [19:52.190] [19:52.190]you will be able to get paid using Monero, using RPC Pay, the RPC Pay feature or Bitcoin or the [20:00.950] [20:00.950]Lightning Network, and you're going to get payments for the services you are providing to others [20:07.650] [20:07.650]inside the Lucha Mesh as a way to incentivize you for running these services inside the Lucha Mesh. [20:14.350] [20:14.350]So, you will be able to build the devices yourself. You will be able to buy the radio models that [20:21.530] [20:21.530]we're going to build, or you can buy the more consumer-ready for newbies device, which is the [20:27.710] [20:27.710]Turpill device. And so, you can have all your family, relatives, and friends have a Turpill [20:33.970] [20:33.970]device that they can carry around with them in order for them to be able to chat with you or [20:39.550] [20:39.550]use the services you are providing to them from your house on your Lucha Mesh-enabled computer. [20:45.910] [20:46.690]So, this is what we wanted to show you, and this is what we've been working [20:53.390] [20:53.390]on for the past two years. And thanks to other communities like the Monero community itself, [21:00.550] [21:00.550]we've been able to do this mostly on donations and grants that we have received. But we also have a [21:09.230] [21:09.230]company, which is the hardware company, that we want to make devices in order to sell them for [21:18.290] [21:18.290]the common users that are not going to build them, but they are going to buy them in order to be [21:23.070] [21:23.550]a node inside the Mesh and be able to provide relay messages for others and maybe get [21:30.230] [21:30.910]payments for providing that service too. So, if you are interested in supporting us, [21:38.750] [21:38.750]you can make a donation or you can join us on GitHub and help us test the devices, [21:45.670] [21:45.670]the DevKit devices that we expect to have pretty soon. Or you can pre-order [21:51.930] [21:52.430]the tour device that we expect to have ready for shipment early 2021. Thank you. [22:03.010] [22:03.850]Thank you, everyone. Luis? Thank you very much, everyone. [22:09.070] [22:11.930]Okay. Thank you. Hope you enjoy the rest of the DevCon. Hope you enjoyed all this weekend, [22:18.670] [22:18.670]which has been very interesting and exciting. And hope to see you again. If you have any questions, [22:24.810] [22:24.810]you can reach out to us at locha.io, L-O-C-H-A dot I-O. And you can find us on Twitter and also [22:34.950] [22:34.950]on GitHub, as said previously. On Twitter, we are locha underscore I-O. Thank you, everyone. [22:42.890] [22:42.890]Thank you for attending. Thank you. [22:46.150]
