WEBVTT 00:00.000 --> 00:01.020 Okay. 00:01.640 --> 00:11.800 So if you are watching right here, right now, then that's because you want to know how Monero's reference implementation GUI wallet works. 00:11.800 --> 00:13.560 You love the idea of Monero. 00:13.560 --> 00:14.860 You listen to all the talks. 00:14.860 --> 00:16.500 You're like, Diego, I need this. 00:16.500 --> 00:17.900 I need this in my life. 00:17.900 --> 00:19.860 I need to get on board with Monero. 00:19.920 --> 00:24.280 But just downloading things and using the wallet, it's all scary. 00:24.280 --> 00:26.280 What if my Monero just disappears? 00:26.280 --> 00:28.160 What if everything just goes away? 00:28.300 --> 00:30.860 So this is the workshop for you. 00:30.860 --> 00:38.040 I'm going to be kind of going through the... I'm going to be going through the Monero wallet, getting everybody comfortable with it. 00:38.040 --> 00:39.600 We're going to send a transaction . 00:39.600 --> 00:41.660 We're going to receive a transaction. 00:41.660 --> 00:44.600 We're going to go ahead and prove a transaction. 00:44.600 --> 00:49.940 So , you know, proving that I did in fact send from one place to another place. 00:49.960 --> 00:58.960 So, you know, and we'll talk about when somebody would want to do that, why they would want to do that, and then we'll go ahead and show you how we would go ahead and do that. 00:58.960 --> 01:05.880 And if you have any questions at any point in time, please, by all means, put them in the... put them in the chat. 01:05.880 --> 01:08.740 I have both a Twitch and a YouTube open. 01:08.740 --> 01:11.560 So I will go ahead and be watching both. 01:11.580 --> 01:12.940 Just put it in either. 01:13.040 --> 01:15.420 If you need me to slow down or any of these things. 01:15.540 --> 01:22.880 Ideally, as we're starting, I would recommend everyone to go to getmonero.org. 01:22.880 --> 01:25.480 There is a place for downloads. 01:26.340 --> 01:37.800 And, you know, as we're getting started here, if you want to follow along, go to getmonero.org slash downloads or click on the downloads in the navigation and go ahead and download the GUI wallet. 01:37.800 --> 01:44.880 Ideally, you would want to do the thing about where you're checking the hashes, which there is instructions for to do there as well. 01:44.880 --> 01:47.880 But we're not going to have time to go through that at present time. 01:47.880 --> 01:50.880 So you can go ahead and do that later. 01:50.880 --> 01:56.900 But you are going to want to check your hashes just to make sure you have the correct software that has not been hijacked or anything. 01:57.340 --> 02:02.720 So I'm going to go ahead and share my screen, if that's okay with everybody. 02:03.160 --> 02:04.700 Let's go ahead and do that. 02:04.700 --> 02:05.920 Just one second. 02:06.260 --> 02:07.040 Okay. 02:07.260 --> 02:11.620 So here is my lovely Monero wallpaper. 02:12.500 --> 02:16.940 And we have a freshly opened Monero GUI. 02:17.140 --> 02:22.440 It's not super freshly open, because when you do first open this, the first thing that you're going to see... oh, it's not this one. 02:22.440 --> 02:24.060 Although, hey, neat little feature. 02:24.060 --> 02:26.860 You can go ahead and switch light mode, dark mode. 02:26.920 --> 02:31.680 But basically, the first thing you're going to do is choose a language, I believe. 02:31.680 --> 02:35.060 Although maybe they updated that and it just takes it from your computer, but I don't think so. 02:35.060 --> 02:39.110 So you can go ahead and choose your language, and you're going to come to this thing. 02:39.310 --> 02:43.430 Simple mode, simple mode bootstrap, advanced mode. 02:43.430 --> 02:44.590 What do you choose? 02:44.590 --> 02:45.950 What do you do? 02:46.170 --> 02:47.770 How does this work? 02:48.310 --> 02:50.130 So this isn't really that scary. 02:50.130 --> 02:55.970 Basically, Monero wallets have two ways of connecting to the Monero network. 02:55.970 --> 02:59.670 Either you can download the blockchain onto your device. 02:59.670 --> 03:06.870 This is the one that has the least amount of trust, because now you're just... all the time, you're working with your own blockchain. 03:07.070 --> 03:09.130 You're not going to be working with anybody else's blockchain. 03:09.130 --> 03:11.070 You don't need to connect to any external computers. 03:11.070 --> 03:13.010 It's just all you, all the time. 03:13.010 --> 03:14.450 So you can do everything locally. 03:14.570 --> 03:17.210 But that's going to take time to download everything. 03:17.210 --> 03:19.010 That's going to take time to verify everything. 03:19.010 --> 03:20.590 That's going to take space. 03:21.050 --> 03:24.550 And right now, Monero blockchain is like, I don't know, like 80-ish. 03:24.550 --> 03:25.750 Somebody can correct me if I'm wrong. 03:25.750 --> 03:26.230 You can look it up. 03:26.230 --> 03:26.950 It's pretty easy. 03:26.950 --> 03:28.190 But 80-ish gigabytes. 03:28.390 --> 03:29.990 So it's a decent amount of space. 03:29.990 --> 03:31.850 It's a small investment. 03:31.850 --> 03:35.670 But with how big hard drives are these days, it's not too awful, I guess. 03:35.870 --> 03:43.450 So if that's what you want to do, you're probably going to want to go with simple mode bootstrap or advanced mode. 03:43.450 --> 03:46.910 And advanced mode just kind of lets you choose all the different things that you want to do. 03:48.010 --> 03:55.250 Simple mode bootstrap has fewer tweaking needed, but it still does put the blockchain onto your computer. 03:55.430 --> 04:09.170 Simple mode does the other way of connecting to the blockchain, which is basically this idea that you don't have the blockchain on your own computer, so you have to connect to somebody else's computer who is available to the internet, and you access their blockchain. 04:09.170 --> 04:16.290 So when you need to send a transaction and you need to kind of do the whole ring signature thing, you take stuff from them. 04:16.290 --> 04:22.990 You still have to scan the chain for your transactions, but you don't have to download the whole thing. 04:22.990 --> 04:25.270 So you're basically scanning somebody else's version. 04:25.890 --> 04:26.990 You don't have to have it on your own. 04:26.990 --> 04:34.670 This is so that way you don't have to use a bunch of bandwidth to put that all on your thing, and also so that way you don't have to store it yourself. 04:34.910 --> 04:42.650 For most people, unless you really want the blockchain, you could just go ahead and click simple mode, and it's going to take you and connect. 04:42.650 --> 04:47.870 It's going to find one of those and connect automatically the one that's going to be the closest to you. 04:48.170 --> 04:52.530 So I'm going to go ahead and click simple mode, and it's going to this thing. 04:52.530 --> 04:53.890 It's like, okay, are you sure? 04:53.890 --> 04:55.150 Just be aware. 04:55.470 --> 04:56.110 Just be aware. 04:56.110 --> 04:59.130 This is not the most private way that you can do it. 04:59.130 --> 05:01.490 Remote nodes could compromise some privacy. 05:01.650 --> 05:03.590 Let me go ahead and make this a little bit bigger. 05:05.850 --> 05:06.490 Wonderful. 05:06.490 --> 05:10.510 So we've made the window bigger, but we haven't scaled the text at all. 05:10.830 --> 05:13.690 I don't know if this is readable on the YouTube. 05:13.690 --> 05:15.430 I don't suspect that it is. 05:18.450 --> 05:19.210 Okay. 05:19.870 --> 05:22.050 We're just going to go ahead and move forward from here. 05:22.050 --> 05:23.010 You can ignore this. 05:23.010 --> 05:29.210 I'm going to go to advanced mode because I already have a local remote node set up that I'm going to connect to at my own place. 05:29.630 --> 05:36.510 But we're just going to pretend that you pressed simple mode and you pressed yes, I understand these consequences, and then you're going to come to here. 05:36.950 --> 05:37.990 Create new wallet. 05:37.990 --> 05:44.270 Create new wallet from hardware, open a wallet file, or restore wallet from keys and So these are pretty self-explanatory. 05:44.430 --> 05:46.370 Create a new wallet is what we're going to go through in just a second. 05:46.370 --> 05:48.750 That is going to let you create a brand new wallet. 05:48.750 --> 05:49.390 Hooray! 05:49.650 --> 05:51.170 Create a new wallet from hardware. 05:51.170 --> 05:56.730 I'm certain if you've been in the blockchain space for any length of time, you've probably heard the names Trezor and Ledger. 05:56.730 --> 05:59.510 These are hardware wallets that you can get. 05:59.530 --> 06:03.410 And they keep the keys on the hardware device. 06:03.410 --> 06:06.170 And in theory, they're supposed to be hard to extract, if not impossible. 06:06.550 --> 06:19.590 And it helps so that way, if you do have a virus on your computer, if you have any of these things, they really can't steal your Monero because all the keys are stored on the hardware and you need the hardware to be connected in order to send a transaction . 06:19.590 --> 06:27.350 So if you have access to one of those devices, you have one of those devices, or you want an extra layer of security, Monero does work with both Trezor and Ledger. 06:28.250 --> 06:32.650 So this is how you would make a new wallet if you were connecting it with the hardware. 06:32.990 --> 06:34.110 Open a wallet from file. 06:34.110 --> 06:38.250 So after you make a new wallet, it gets put on your file system. 06:38.250 --> 06:47.650 And so if you have multiple wallets for whatever reason, your wife has a wallet, your husband has a wallet, your dog has a wallet, and all of you guys have separate bank accounts, so to speak, right? 06:47.650 --> 06:52.790 You can click on this and navigate between wallets, if you have multiple ones on the computer. 06:53.330 --> 06:55.450 Restoring a wallet from keys or mnemonic seed. 06:55.450 --> 06:58.310 In just a second, when we create a new wallet, we're going to see what a seed looks like. 06:58.310 --> 07:02.550 It's basically 25 words that we're going to need to write down. 07:02.770 --> 07:14.190 And if your computer dies, if your phone dies, wherever the wallet is stored, you will be able to get your Monero by clicking on this option and typing those seeds in. 07:15.050 --> 07:19.370 And I will greatly stress the importance of seeds here in just a minute. 07:19.490 --> 07:22.090 They're extremely, extremely important. 07:22.130 --> 07:25.090 Is this bugging people that you want it more in the middle? 07:25.510 --> 07:27.290 I mean, yeah, we'll put it more in the middle. 07:27.290 --> 07:27.730 I don't know. 07:27.730 --> 07:29.810 Maybe some people are annoyed by that. 07:30.810 --> 07:32.410 So we're just going to go ahead. 07:32.410 --> 07:33.910 You can go ahead and ignore these ones right here. 07:33.910 --> 07:36.390 Change you back to simple, advanced, whatever. 07:36.650 --> 07:38.890 And change language is pretty self-explanatory. 07:38.890 --> 07:40.270 So we're going to go and create a new wallet. 07:40.830 --> 07:41.490 Okay. 07:41.770 --> 07:43.350 First thing we're going to find out. 07:43.490 --> 07:49.530 So on this virtual machine, I just named it funsies just because this is for funsies. 07:50.270 --> 07:52.610 And there is a wallet location. 07:52.610 --> 07:54.710 So this is where your wallet is actually going to be stored. 07:54.710 --> 07:57.410 You can click browse and change where that's going to be. 07:57.410 --> 07:57.830 Okay. 07:57.850 --> 08:00.030 So you can give your wallet a name. 08:00.030 --> 08:02.770 I'm going to call this Defcon new. 08:02.770 --> 08:04.230 You can name it whatever you want. 08:04.570 --> 08:08.010 Now we get to this thing, the mnemonic seed. 08:08.330 --> 08:15.570 And this is the single most important thing that you're going to do when you make a new wallet. 08:15.690 --> 08:20.130 You need to write these words down. 08:20.290 --> 08:26.410 You need to get out a pencil and a paper, 10 papers, and write these words down. 08:26.410 --> 08:26.930 Okay. 08:26.930 --> 08:38.470 If you lose your wallet, meaning your computer dies, or it explodes, your house catches fire, and you don't get to save anything, you know, anything could happen. 08:38.470 --> 08:46.950 If you lose your computer, if you lose your wallet, but you have these words, then you have your Monero. 08:47.390 --> 08:56.670 If you lose your wallet and you do not have these words, then you have lost your Monero and nobody can help you get them back. 08:56.670 --> 09:01.470 These words are like a human readable representation of your private key. 09:01.970 --> 09:05.830 So if you do not have these words, you don't have your Monero. 09:05.830 --> 09:12.430 And further, if somebody else sees these words, they now have your Monero. 09:12.430 --> 09:18.770 Your wallet has no way to distinguish between whether that person is the actual owner of the wallet or not. 09:18.770 --> 09:22.950 All they know is, okay, they have access to these words, so they can spend the Monero. 09:22.970 --> 09:25.690 If you have these words, you can spend your Monero. 09:25.690 --> 09:26.850 So you need to write them down. 09:26.850 --> 09:33.250 It's not recommended to put them digitally, because what happens if your computer gets hacked or any number of things, right? 09:33.250 --> 09:44.150 And it's important that you have more than one of these in a very safe place, because if you only have one paper copy and it gets burned up, or something happens to it, or there's a flood, then you have lost your Monero. 09:44.250 --> 09:47.410 You must, must write this down. 09:47.410 --> 09:48.770 Do it now. 09:48.770 --> 09:49.850 Do it now. 09:50.070 --> 09:59.970 And for this particular presentation, I mean, I just pressed brand new, so if I click back to menu and create a new one, you're going to see that it's a new set of seed. 09:59.970 --> 10:00.690 It's a new set. 10:00.690 --> 10:02.630 It's just going to be different every time. 10:03.110 --> 10:07.590 So I would not recommend writing these down. 10:07.590 --> 10:13.510 I also would not recommend using the wallet with this seed for anything, because now this is available to the public. 10:13.510 --> 10:16.210 This is available on YouTube, on Twitch. 10:16.210 --> 10:23.870 And if anyone's writing this down, hoping, okay, Diego's going to be sending money to this wallet to prove things, and I'll just steal it, because I have the seed, ha-ha, you're mistaken. 10:23.870 --> 10:25.890 I have other wallets set up that we're going to do that for. 10:26.030 --> 10:28.010 So write this down. 10:28.090 --> 10:29.890 Don't send to this one. 10:30.370 --> 10:31.890 Don't send to this one. 10:32.810 --> 10:33.770 Wallet restore height. 10:33.770 --> 10:34.850 What does this mean? 10:34.890 --> 10:39.050 This is basically... so Monero's chain is really, really big. 10:39.050 --> 10:41.270 I told you it's several, several gigabytes large. 10:41.570 --> 10:52.430 And if you make a brand new wallet, right, if you make a brand new wallet, why would you want to scan the whole chain to see if you have any transactions? 10:52.430 --> 10:55.650 Because in theory, if it's a new wallet, you have no previous transactions. 10:55.850 --> 10:58.230 If you're restoring a wallet, then maybe it's important. 10:58.230 --> 11:00.470 But for a brand new wallet, it's not important. 11:00.470 --> 11:05.630 So we're telling it, okay, start 2 million blocks up. 11:05.630 --> 11:07.250 Don't start at block zero. 11:07.550 --> 11:09.450 Start 2 million blocks up. 11:09.470 --> 11:13.210 And the GUI's going to chew something to you relatively close. 11:13.210 --> 11:15.530 So we're going to go ahead and click next here. 11:16.610 --> 11:18.670 This is where you're going to put your password. 11:18.790 --> 11:19.030 Okay. 11:19.030 --> 11:23.230 If you forget your password, but you have your seed, then you have your Monero. 11:23.230 --> 11:27.850 If you forget your password and you don't have your seed, you don't have your Monero. 11:27.850 --> 11:29.330 So the seed is the most important thing. 11:29.330 --> 11:30.170 Write it down. 11:30.170 --> 11:38.350 The password is to make sure that anyone who gets access to your computer that maybe shouldn't have access to your computer can't send your Monero away or something. 11:38.350 --> 11:40.770 Because it doesn't require you to put in your seed every time. 11:40.810 --> 11:42.470 And we'll see that in just a moment. 11:42.650 --> 11:45.610 So I'm going to go ahead and click next. 11:45.610 --> 11:47.270 You can put no password here. 11:47.270 --> 11:48.350 I would not recommend it. 11:48.350 --> 11:50.610 But for these purposes, this is what I'm going to do. 11:52.550 --> 11:55.710 I do have a bootstrap node. 11:55.710 --> 11:56.850 So just one second. 11:56.850 --> 11:58.050 This should have been already filled in. 11:58.050 --> 11:59.490 But it's not. 11:59.590 --> 12:01.070 Which is a little annoying. 12:01.930 --> 12:03.450 Just one second. 12:04.610 --> 12:12.090 This is where I have put my temporary node. 12:12.090 --> 12:13.810 So now you all know where that is. 12:13.830 --> 12:14.650 Fantastic. 12:14.670 --> 12:15.330 Uh-oh. 12:15.330 --> 12:15.610 No. 12:15.610 --> 12:16.430 Connect to a remote. 12:16.510 --> 12:17.930 Do it here. 12:18.010 --> 12:18.630 Do it here. 12:18.630 --> 12:19.110 Okay. 12:19.110 --> 12:20.070 Create wallet. 12:20.630 --> 12:23.990 So here's where you would be putting in your password if you had one. 12:24.670 --> 12:27.170 I just press okay because I didn't put a password for this. 12:27.170 --> 12:28.430 And you come to this screen. 12:28.430 --> 12:29.290 And you see okay. 12:29.290 --> 12:30.210 Now we're scanning. 12:30.210 --> 12:32.050 But it's not from the beginning of the blockchain. 12:32.050 --> 12:34.210 It's from block 2 million. 12:34.210 --> 12:34.690 And bam. 12:34.690 --> 12:35.110 It's done. 12:35.110 --> 12:35.910 Super quick. 12:35.910 --> 12:38.010 This would have taken a long time. 12:38.010 --> 12:40.830 Hours, probably, if it was scanning from the beginning. 12:40.930 --> 12:43.410 But once it scans once, it doesn't have to do it again. 12:43.430 --> 12:52.770 So if you do scan from the beginning, then after it's gone through those hours, the next time you open your wallet, it won't have to do that process every single time. 12:52.770 --> 12:53.870 It's just that once. 12:54.170 --> 12:56.350 So we've got several screens over here. 12:56.350 --> 12:58.330 The GUI starts you out on the send screen. 12:58.570 --> 13:07.010 And as you can see, we're gonna put the address that you want to send to, the amount that you want to send, your transaction priority, which determines the fee that you give the miners. 13:07.010 --> 13:11.230 The higher the fee, the more likely you're gonna get in, unless the blocks aren't super full. 13:11.330 --> 13:14.110 In which case, pretty much everybody's gonna get in. 13:14.110 --> 13:17.590 So if we click on this, you can see slow, normal, fast, fastest. 13:17.590 --> 13:20.510 These are how much fee you can put. 13:21.110 --> 13:23.590 Monero also has this cool thing where you can add a description. 13:25.070 --> 13:26.710 Just for your personal thing. 13:26.710 --> 13:30.990 So when you send a transaction, you're like, oh, I sent this to my cousin for this reason. 13:30.990 --> 13:32.530 And so you just know what everything's for. 13:32.890 --> 13:34.230 We also have an address book. 13:34.230 --> 13:40.390 So if you use, you know, if you're paying an employee and you do it consistently every month, you can save their address here. 13:40.390 --> 13:42.210 So you don't have to ask them for it every time. 13:42.250 --> 13:43.290 Why would we want to do that? 13:43.290 --> 13:46.470 Well, if you've never seen a Monero address before, let's go to the receive screen. 13:48.310 --> 13:51.310 And this address is very, very long. 13:51.310 --> 13:52.970 You can't see it here because it's truncated. 13:52.970 --> 13:57.330 So actually, let's go ahead and open up a notepad. 13:58.150 --> 13:58.850 Boom. 13:58.850 --> 14:00.770 This is what it looks like. 14:01.050 --> 14:01.270 Okay. 14:01.270 --> 14:02.770 This is a Monero address. 14:02.770 --> 14:03.850 It's very long. 14:03.850 --> 14:05.590 It's very, very, very long. 14:05.650 --> 14:09.370 So you can't call your grandma and be like, okay, grandma, here it is. 14:09.370 --> 14:15.250 It's four, five, lowercase p, lowercase h, lowercase p, uppercase L. 14:15.250 --> 14:18.210 You can see how that's going to be prone to errors and stuff. 14:18.210 --> 14:20.590 So you really got to copy and paste it in every time. 14:20.610 --> 14:21.930 You got to ask for it. 14:21.930 --> 14:26.950 So the addresses, saved addresses on your address book is going to help with that. 14:27.550 --> 14:29.010 You also have a QR code. 14:29.010 --> 14:30.390 This is the same thing as this. 14:30.390 --> 14:34.370 So if you scan this QR code, we do have mobile wallets available. 14:34.690 --> 14:38.550 Cake wallet for iOS and Android and Monero for Android as well. 14:38.550 --> 14:40.610 You can go ahead and scan that. 14:41.610 --> 14:43.750 And send to it rather quickly. 14:44.010 --> 14:46.370 Transactions is going to be a list of transactions. 14:46.410 --> 14:49.350 Because this is a brand new wallet, we don't have anything here yet. 14:49.350 --> 14:51.890 And I'll show you one of the other wallets that I've made here pretty quick. 14:54.590 --> 14:56.210 Advanced for the most part. 14:56.210 --> 14:57.550 We're not going to cover those. 14:57.550 --> 14:58.650 It's outside of the scope. 14:58.650 --> 15:00.110 I've only got about 15 minutes left. 15:00.110 --> 15:01.670 And we still need to do some things. 15:02.090 --> 15:03.490 But you can mine from this. 15:03.490 --> 15:06.050 The only one we are going to touch on is this prove and check. 15:06.050 --> 15:07.610 This is how we're going to prove a transaction. 15:07.610 --> 15:09.130 And we're going to get to that in just a minute. 15:09.390 --> 15:11.690 Settings is where you adjust some things in the wallet. 15:11.690 --> 15:14.110 And you can go ahead and click around those and see for yourself. 15:14.910 --> 15:15.590 Accounts. 15:15.590 --> 15:17.650 We're not going to go ahead and worry about accounts for now. 15:17.650 --> 15:24.590 But there's just this idea that you can generate multiple subaddresses, which are addresses that link back to this one address. 15:24.590 --> 15:28.230 So, you can make multiple subaddresses that all go down to this one thing. 15:28.230 --> 15:31.330 And you don't have to have new seeds or make new wallets or anything like that. 15:31.330 --> 15:34.110 You can also do this from the receive screen. 15:34.110 --> 15:35.270 Create new address. 15:35.290 --> 15:35.970 What is this? 15:35.970 --> 15:38.070 This is subaddress 1. 15:38.930 --> 15:41.210 And Monero addresses start with 4. 15:41.210 --> 15:42.590 Subaddresses start with 8. 15:42.590 --> 15:47.690 And you see that the QR code changes every time to match the thing. 15:47.690 --> 15:47.930 Okay. 15:47.930 --> 15:49.570 So, this is the new wallet. 15:50.090 --> 15:55.110 We're gonna go ahead and push this aside because we know the seed for this wallet. 15:55.110 --> 15:56.350 The seed is for everybody. 15:56.370 --> 15:58.210 So, we're gonna go ahead and push this aside. 15:58.410 --> 16:03.590 And I'm going to grab some other wallets and bring them onto the screen. 16:05.730 --> 16:09.270 And here, we have Defcon send and Defcon receive. 16:09.270 --> 16:11.030 Let's go ahead and put this this way. 16:11.990 --> 16:14.810 Both of these, you don't know the seed for them. 16:14.810 --> 16:16.110 That's the point. 16:16.110 --> 16:17.870 But they do have some Monero on them. 16:17.870 --> 16:19.450 This one has three Monero on it. 16:19.450 --> 16:21.210 This one has one Monero. 16:21.390 --> 16:23.510 And we're gonna go through a couple of the flows. 16:23.510 --> 16:26.890 Before I move on, let's see if there's any questions. 16:26.970 --> 16:28.230 Blah, blah, blah. 16:29.370 --> 16:31.130 What about JavaScript? 16:31.130 --> 16:32.170 What about JavaScript? 16:32.170 --> 16:33.110 I don't understand. 16:35.490 --> 16:35.930 Okay. 16:35.930 --> 16:36.710 I think we're good. 16:37.410 --> 16:38.230 All righty. 16:38.590 --> 16:46.430 So, as we can probably tell by the names of the wallet, Defcon send is going to be sending to Defcon receive. 16:46.750 --> 16:48.910 So, how we're gonna do that, it's as simple as this. 16:48.930 --> 16:51.010 On the wallet that you want to receive from. 16:51.010 --> 16:54.870 So, if you are the recipient of money, you're going to go to receive. 16:54.870 --> 16:56.370 You're going to copy this. 16:56.370 --> 16:59.050 If you press this icon, it copies the address to clipboard. 16:59.270 --> 17:04.030 Or you can give them this QR code, which you can save as an image or also copy that to clipboard. 17:04.270 --> 17:09.010 And on the wallet that's send, if you're the sender, you're gonna go ahead and paste this in here. 17:09.030 --> 17:13.190 Now, you want to double check the address. 17:13.190 --> 17:22.470 Because there are there is malware out there that will replace the address in your clipboard with their own. 17:22.690 --> 17:24.170 And you want to double check that. 17:24.170 --> 17:26.930 You want to make sure that this address didn't get replaced. 17:26.930 --> 17:28.630 You don't have to do the whole thing. 17:29.510 --> 17:34.390 So, in this case, we see 47BXR3PB. 17:34.530 --> 17:43.090 And if we look here at the recipient address, we indeed see 47BXR3PBMKWI. 17:43.190 --> 17:47.270 And this truncates it, but it also has some at the end. 17:47.510 --> 17:51.170 You know, the last four are LQCW. 17:51.170 --> 17:58.230 If you want to be 100% sure that you're the correct address, you verify the entire thing. 17:58.510 --> 18:03.710 Most people, like, if you just do the first four and the last four, that's probably too little. 18:04.090 --> 18:07.590 Because it may be easy for somebody to generate something that looks similar. 18:09.150 --> 18:12.030 Verifying any of them is better than nothing. 18:12.230 --> 18:22.590 But, you know, verifying the first maybe 10, 16, the last 10, 16, it's the more you verify, the harder it is for somebody to kind of cheat you and make it so that way you don't know what's going on. 18:22.590 --> 18:24.590 So we've went ahead and put this in here. 18:24.650 --> 18:28.990 We can go ahead and add this to our address if we want to. 18:29.150 --> 18:31.170 I'm not going to go and do that, but you can go ahead and do that. 18:31.170 --> 18:33.710 If you click this, it'll take you to the address book. 18:34.010 --> 18:34.390 You know what? 18:34.390 --> 18:35.230 I am going to go ahead and do that. 18:35.230 --> 18:36.270 I'm going to add an address. 18:36.510 --> 18:38.110 And this is Diego. 18:39.290 --> 18:40.510 He's so cool. 18:41.570 --> 18:41.790 All right. 18:41.790 --> 18:43.590 So that's what this is added as. 18:43.590 --> 18:49.270 So now from the address book, I can actually click on this and it will autofill on the address here. 18:49.270 --> 18:50.470 It will autofill that. 18:50.650 --> 18:54.910 So I'm going to go ahead and send Def Con receive one Monero. 18:56.250 --> 19:03.670 For the most part, we're just going to like automatic on transaction priority is going to be okay for 99% of the time. 19:03.670 --> 19:06.050 I don't recommend touching this unless you know what you're doing. 19:06.150 --> 19:09.810 Advanced options, we don't really need any of this, so let's not worry about it. 19:09.910 --> 19:12.150 So now it's creating the transaction. 19:12.150 --> 19:15.610 It's building the ring signature, getting the cryptography ready, all this stuff. 19:15.610 --> 19:17.550 It's like, okay, this is where you're sending it to. 19:17.550 --> 19:18.530 This is the amount. 19:18.530 --> 19:19.370 This is the fee. 19:19.370 --> 19:20.630 Here's the ring size. 19:21.170 --> 19:22.150 Here's the description. 19:22.150 --> 19:23.250 Does all this sound good? 19:23.830 --> 19:24.390 Yes. 19:24.550 --> 19:25.070 Okay. 19:25.570 --> 19:30.670 It's going to prompt you to put in your password, which if we had one, I'd put it, but we don't, so I'm just going to press okay. 19:30.790 --> 19:31.370 All right. 19:31.850 --> 19:36.110 Monero sent successfully, is what this says, because I think it's a little too small and blurry for everybody to see. 19:36.270 --> 19:37.530 Monero sent successfully. 19:38.030 --> 19:42.030 And then it's got this huge long string of alphanumeric string. 19:42.070 --> 19:45.170 This is your transaction ID, and we're going to come back to this when we prove transactions. 19:45.170 --> 19:51.910 You can go to a Monero block explorer and put this in there, and we can see when it comes out. 19:52.590 --> 19:53.290 Okay. 19:53.370 --> 20:05.150 So I just sent one Monero, and if we go to transactions, we can see... you've seen here on the transaction screen, you can see that I have put some Monero onto this wallet for these purposes. 20:05.150 --> 20:06.710 These are the past transactions. 20:08.150 --> 20:14.370 I sent one XMR 28 seconds ago to this address. 20:14.370 --> 20:15.610 And boom! 20:15.690 --> 20:19.450 Oh, wait, no, this is the one that we have already that was already on here. 20:19.590 --> 20:22.330 If we click on transactions, you'll see... ha-ha! 20:22.710 --> 20:23.690 We do have one. 20:23.690 --> 20:26.770 This was the one that was already on here, but this was 46 seconds ago. 20:26.770 --> 20:31.050 The reason it's not showing up here is because it needs to be included in a block first. 20:31.050 --> 20:37.170 If you don't understand how a blockchain works, transactions need to be included in blocks, which then need to be mined and da-da-da-da-da. 20:37.630 --> 20:41.450 There's a lot of great resources out there that talk about how a blockchain works from the ground up. 20:41.450 --> 20:43.630 I would recommend giving it a look. 20:44.210 --> 20:53.550 But although that isn't super important right now, Monero's block time is two minutes, which means that the average amount of time it takes to find one block is two minutes. 20:53.810 --> 20:57.550 So this will be about two minutes, but it may be more, it may be less. 20:57.550 --> 21:01.950 It depends on the luck of the miners before this is going to start showing up here. 21:03.210 --> 21:05.970 So that is the send and receive flow. 21:05.970 --> 21:07.490 It's really not difficult. 21:07.490 --> 21:11.810 If you want to be the sender, you just got to know the address, know how much you're going to send to them. 21:11.810 --> 21:18.050 You can send all of your Monero there if you want and set a fee, which automatic is going to be okay most of the time. 21:18.050 --> 21:30.530 If you're the receiver, you're going to either copy the address and give it to them, double check that it wasn't replaced, or they can scan this QR code, which you can save as an image and send to them or whatever the case may be. 21:30.530 --> 21:37.110 In all cases, you're going to want to check to make sure that the alphanumeric string was not changed and the QR code was not changed. 21:37.230 --> 21:40.270 You just want to make sure that it's actually going to go where you want it to go. 21:40.270 --> 21:44.870 Because if you accidentally send to the wrong address, you have no way of getting that money back. 21:44.870 --> 21:46.250 There's nobody to call. 21:46.290 --> 21:48.210 There's no customer service. 21:48.250 --> 21:49.550 There's nobody who can get it for you. 21:49.550 --> 21:52.610 It's all cryptographically enforced and nobody can save you. 21:54.070 --> 21:56.550 So we're going to go ahead and prove a transaction really fast. 21:56.550 --> 21:58.170 And I hope this goes well. 21:58.170 --> 21:59.330 I hope this goes okay. 21:59.330 --> 22:08.290 This is the reason why I put a previous transaction of one because I don't want to wait for this one to come into a block before we start proving. 22:08.290 --> 22:10.570 So this one was sent three hours ago. 22:11.090 --> 22:17.730 And we're going to prove that this DEFCON send did in fact send to this DEFCON receive. 22:17.730 --> 22:28.190 So if you imagine that DEFCON receive is a merchant and DEFCON send, they purchased something in Monero from that merchant and the merchant says, oh, well, I didn't receive this Monero. 22:28.410 --> 22:29.950 I didn't get it. 22:29.950 --> 22:31.430 You can prove that you did. 22:31.430 --> 22:34.670 So let's go ahead and go to advanced and proof check. 22:35.130 --> 22:37.950 And here advanced proof check as well. 22:37.970 --> 22:40.510 So we need the transaction ID. 22:40.610 --> 22:42.810 So actually, let's go back to transactions. 22:42.810 --> 22:45.110 This was the one that I sent prior. 22:45.150 --> 22:49.130 And if we click on this, we see that there's details that drop down. 22:49.130 --> 22:50.190 Here's the transaction ID. 22:50.190 --> 22:52.210 You just find what's labeled transaction ID. 22:52.510 --> 22:55.970 And we just left click on it and it automatically copies it to clipboard. 22:55.970 --> 22:56.670 Great. 22:56.670 --> 23:01.790 So we're going to go to advanced proof check and paste in this transaction ID. 23:02.470 --> 23:04.370 Let's just double check that it's correct. 23:05.950 --> 23:07.490 A89BB64 blah, blah, blah, blah, blah. 23:07.490 --> 23:07.830 Yeah. 23:07.830 --> 23:08.650 It's all good. 23:10.610 --> 23:11.590 The address. 23:11.590 --> 23:13.570 We have to know what address we sent to. 23:13.570 --> 23:22.690 Once again, if you go to transactions, it has in the data about the transaction at the bottom, it has the address to send to. 23:24.910 --> 23:26.190 It's this one right here. 23:27.370 --> 23:33.330 So we're going to go ahead and copy this and put it in this proof check. 23:33.730 --> 23:35.590 Now, you can put an optional message here. 23:35.590 --> 23:38.970 And this is just an extra kind of fail safe. 23:39.090 --> 23:43.130 But the other person has to put this exact same message, otherwise it's not going to check correctly. 23:43.130 --> 23:46.990 So we're going to go ahead and put Defcon as the message here. 23:46.990 --> 23:48.350 Now, we're going to click generate. 23:49.910 --> 23:53.730 Now, once we click generate, it gives me this payment proof. 23:54.050 --> 23:57.290 This thing that starts with out proof V1 something, something. 23:57.890 --> 24:01.190 So we're going to copy this, double tap to copy the clipboard. 24:01.190 --> 24:04.410 And we would send this to the recipient. 24:04.410 --> 24:07.110 We would send this to them and say, this is the proof. 24:07.110 --> 24:08.150 This is the proof. 24:08.290 --> 24:08.510 Okay. 24:08.510 --> 24:09.630 Now, I'm the merchant. 24:09.630 --> 24:11.990 I want to say, okay, Diego says he sent it to me. 24:12.450 --> 24:14.570 For some reason, I'm not seeing it or I don't know. 24:14.570 --> 24:14.890 Okay. 24:14.890 --> 24:16.230 Let's go ahead and check this out. 24:16.230 --> 24:18.710 We're going to scroll down to the second part, check a transaction. 24:20.850 --> 24:23.510 The first thing we're going to do, we're going to paste in the signature. 24:23.630 --> 24:26.010 The out proof something, something, something that it gave to me. 24:26.550 --> 24:26.890 Okay. 24:26.930 --> 24:28.370 The transaction ID. 24:28.790 --> 24:30.130 I'm just going to copy it from here. 24:30.130 --> 24:32.470 But the transaction ID is a public thing. 24:32.470 --> 24:33.790 It's known to everybody. 24:33.790 --> 24:37.450 So sharing this or you can get it from the block explorer or whatever, it's not a big deal. 24:37.470 --> 24:38.930 I'm going to put that here as well. 24:39.090 --> 24:41.190 The address, I know what my address is. 24:41.190 --> 24:43.590 It's the address that I told them to send to me on. 24:43.890 --> 24:45.770 Oh, by the way, the other one has popped up now. 24:45.770 --> 24:46.910 So we have one, not two. 24:47.350 --> 24:48.170 And the message. 24:48.170 --> 24:51.550 If we put an optional message, once again, it has to be the exact same thing. 24:51.550 --> 24:54.550 So I have to put Defcon or whatever it is that they put. 24:54.550 --> 24:55.890 And we're going to click check. 24:57.050 --> 25:06.450 And it says, okay, this address, if it's too small for you guys to read, it says this address received one Monero with 107 confirmations. 25:06.470 --> 25:12.830 This says you did indeed receive one Monero and there is 107 blocks on top of it. 25:12.830 --> 25:16.050 So you can look 107 blocks back and that's where you're going to find it. 25:16.170 --> 25:21.470 If any of these things is incorrect, so if we put an incorrect here and we click check, it's a bad signature. 25:21.470 --> 25:22.210 That's what it's going to say. 25:22.210 --> 25:24.550 It's going to say, nope, this isn't real, this isn't correct. 25:24.550 --> 25:30.630 So if the signature is not right or the address is not right or the transaction ID is not right, all of that stuff is going to be incorrect. 25:30.690 --> 25:45.510 It's only when everything matches 100%, which because everything is cryptographically generated, there is zero chance that if you put in everything correctly, the transaction ID, the address and the message that it will say bad. 25:45.650 --> 25:47.890 It's only if there's a big flaw in the software. 25:48.030 --> 25:52.090 Because all of the cryptography checks out, it's mathematically enforced, there's no way for somebody to... 25:53.710 --> 25:59.250 there's no way for a merchant to cheat you out and say, no, I didn't receive it. 25:59.430 --> 26:08.110 When you're watching them put in the ID, the address, the message and the signature and you verify that everything is correct, there's no way that this will be incorrect. 26:08.110 --> 26:10.870 So the address received one Monero. 26:10.870 --> 26:11.510 Great. 26:11.510 --> 26:12.250 Awesome. 26:12.630 --> 26:17.150 So that's how to prove and check a transaction. 26:18.090 --> 26:19.850 Not all wallets. 26:19.850 --> 26:23.350 So most mobile wallets and stuff come with this capability. 26:24.430 --> 26:31.730 So if you do need to prove or check a transaction, then, you know, where the ecosystem is still developing and blah, blah, blah. 26:31.730 --> 26:33.070 But there is a way to do it. 26:33.070 --> 26:34.610 There is a way to do it. 26:34.610 --> 26:36.370 And that's what I just showed you right here. 26:36.370 --> 26:39.250 That's the basics of the Monero wallet. 26:39.290 --> 26:40.790 As we're closing in, I got four minutes. 26:40.790 --> 26:43.710 That's the basics of Monero wallet and how it works. 26:45.470 --> 26:52.690 The last thing I'm gonna talk with you about is that this one Monero that I received, it's not yet spendable. 26:52.690 --> 26:56.190 You can see it says confirmations, 6 out of 10. 26:56.310 --> 27:01.650 The Monero protocol kind of has it so you have to wait 10 blocks before you can spend it again. 27:01.650 --> 27:07.930 And that's just a safety precaution to make sure that every organization doesn't ruin your transaction. 27:07.930 --> 27:10.210 And if that's a little technical, then I apologize. 27:10.210 --> 27:12.610 I don't have time to get into that at the moment. 27:12.610 --> 27:15.690 So are there any questions from anywhere? 27:17.090 --> 27:19.010 Can you please make the wallet a little bigger? 27:19.010 --> 27:19.310 Thanks. 27:19.310 --> 27:20.150 I'm sorry. 27:20.150 --> 27:21.830 I wish I could. 27:21.830 --> 27:26.810 But as you can see, when I make it bigger, the white space gets bigger. 27:27.430 --> 27:32.750 And the rest of the stuff doesn't. 27:32.750 --> 27:36.950 It's because the DPI of my monitor is too high, unfortunately. 27:38.950 --> 27:41.550 I don't know if there is a way to increase the size. 27:41.550 --> 27:42.770 Let's check it out. 27:42.950 --> 27:43.910 Settings. 27:44.590 --> 27:45.550 Interface. 27:47.010 --> 27:49.990 There's no way to change the size in there. 27:49.990 --> 27:52.270 You'd have to change it in the window settings or something. 27:52.650 --> 27:59.370 No, there's currently no way for us to make the interface bigger. 27:59.370 --> 28:01.610 That's something that should probably be there. 28:01.610 --> 28:02.530 We can talk. 28:02.530 --> 28:07.270 Maybe I'm just an idiot and it really is there and I just don't know. 28:07.590 --> 28:07.970 Yeah. 28:07.970 --> 28:10.950 So I do apologize for everybody. 28:11.610 --> 28:16.010 I do apologize, everybody, that the wallet transactions are so small. 28:16.010 --> 28:20.190 I hope you're able to squint and get a little bit of an idea. 28:20.310 --> 28:23.070 At the very least, where the general things are supposed to go. 28:23.070 --> 28:27.770 It's pretty self-explanatory where all the things are very neatly labeled. 28:28.510 --> 28:31.650 So hopefully this was marginally useful. 28:31.650 --> 28:38.070 If you get nothing else from this talk because everything is too small, write down your seed. 28:38.450 --> 28:40.010 Write down your seed. 28:40.090 --> 28:41.590 Remember that thing at the beginning? 28:41.590 --> 28:43.050 Those 25 words? 28:43.050 --> 28:43.910 Write them down. 28:43.910 --> 28:44.970 Write down your seed. 28:44.970 --> 28:45.610 Write it down. 28:45.610 --> 28:48.110 If you have your seed, you have your Monero. 28:48.110 --> 28:51.790 If you don't have your seed, you don't have your Monero. 28:51.790 --> 28:53.030 Write it down. 28:53.850 --> 28:55.730 And that's basically it for me, guys. 28:55.890 --> 28:57.490 Hope it was useful. 28:57.550 --> 28:59.030 Glad you all came. 29:00.970 --> 29:13.210 This will be available... you know, I'll probably record myself doing this a second time where you can actually see things if they're not too small. 29:13.650 --> 29:19.450 And we'll try to make that available on the Monero community YouTube channel that you're watching this on. 29:19.450 --> 29:23.250 So if you are still confused because you couldn't see anything, then be watching out for that. 29:23.250 --> 29:26.490 Hopefully within a week or so we can get that done and get that uploaded. 29:28.770 --> 29:31.010 That's it for me, ladies and gentlemen. 29:31.010 --> 29:35.450 We've got a meme competition coming up here fairly soon. 29:35.450 --> 29:39.150 I'm going to stop sharing my screen so you can see my lovely face. 29:39.210 --> 29:41.750 Hey, this is the guy that's been talking to you this whole time. 29:41.810 --> 29:42.870 Diego Sauzar. 29:43.110 --> 29:43.470 Rebrar.
