0	8840	Okay. So if you are watching right here, right now, then that's because you want to know how
8840	13840	Monero's reference implementation GUI wallet works. You love the idea of Monero. You listen
13840	18580	to all the talks. You're like, Diego, I need this. I need this in my life. I need to get
18580	24280	on board with Monero. But just downloading things and using the wallet, it's all scary.
24280	30040	What if my Monero just disappears? What if everything just goes away? So this is the
30040	35620	workshop for you. I'm going to be kind of going through the... I'm going to be going
35620	39200	through the Monero wallet, getting everybody comfortable with it. We're going to send a
39200	44820	transaction. We're going to receive a transaction. We're going to go ahead and prove a transaction.
44820	51100	So, you know, proving that I did in fact send from one place to another place. So, you know,
51100	56040	and we'll talk about when somebody would want to do that, why they would want to do that,
56040	59380	and then we'll go ahead and show you how we would go ahead and do that. And if you have
59380	65400	any questions at any point in time, please, by all means, put them in the... put them in the
65400	71880	chat. I have both a Twitch and a YouTube open. So I will go ahead and be watching both. Just
71880	79400	put it in either. If you need me to slow down or any of these things. Ideally, as we're starting,
79400	87320	I would recommend everyone to go to getmonero.org. There is a place for downloads. And, you know,
87320	92680	as we're getting started here, if you want to follow along, go to getmonero.org slash downloads
92680	98220	or click on the downloads in the navigation and go ahead and download the GUI wallet. Ideally,
98220	103080	you would want to do the thing about where you're checking the hashes, which there is instructions
103080	107880	for to do there as well. But we're not going to have time to go through that at present time.
107880	113020	So you can go ahead and do that later. But you are going to want to check your hashes just to
113020	116900	make sure you have the correct software that has not been hijacked or anything.
117340	122720	So I'm going to go ahead and share my screen, if that's okay with everybody.
123160	131620	Let's go ahead and do that. Just one second. Okay. So here is my lovely Monero wallpaper.
132500	139720	And we have a freshly opened Monero GUI. It's not super freshly open, because when you do first
139720	143000	open this, the first thing that you're going to see... oh, it's not this one. Although, hey,
143000	148140	neat little feature. You can go ahead and switch light mode, dark mode. But basically,
148680	152660	the first thing you're going to do is choose a language, I believe. Although maybe they updated
152660	155770	that and it just takes it from your computer, but I don't think so. So you can go ahead and
156430	162150	choose your language, and you're going to come to this thing. Simple mode, simple mode bootstrap,
162150	169410	advanced mode. What do you choose? What do you do? How does this work? So this isn't really
169410	175970	that scary. Basically, Monero wallets have two ways of connecting to the Monero network.
175970	182330	Either you can download the blockchain onto your device. This is the one that has the least amount
182330	186870	of trust, because now you're just... all the time, you're working with your own blockchain.
187070	189650	You're not going to be working with anybody else's blockchain. You don't need to connect
189650	194450	to any external computers. It's just all you, all the time. So you can do everything locally.
194570	198410	But that's going to take time to download everything. That's going to take time to verify
198410	203670	everything. That's going to take space. And right now, Monero blockchain is like, I don't know,
203670	207430	like 80-ish. Somebody can correct me if I'm wrong. You can look it up. It's pretty easy. But 80-ish
207430	213170	gigabytes. So it's a decent amount of space. It's a small investment. But with how big hard drives
213170	218390	are these days, it's not too awful, I guess. So if that's what you want to do, you're probably
218390	224350	going to want to go with simple mode bootstrap or advanced mode. And advanced mode just kind of
224350	230570	lets you choose all the different things that you want to do. Simple mode bootstrap has fewer
230570	236330	tweaking needed, but it still does put the blockchain onto your computer. Simple mode does
236330	241010	the other way of connecting to the blockchain, which is basically this idea that you don't have
241010	245870	the blockchain on your own computer, so you have to connect to somebody else's computer who is
245870	250510	available to the internet, and you access their blockchain. So when you need to send a transaction
251050	256430	and you need to kind of do the whole ring signature thing, you take stuff from them. You
256430	263070	still have to scan the chain for your transactions, but you don't have to download the whole thing. So
263070	267290	you're basically scanning somebody else's version. You don't have to have it on your own. This is
267710	271490	so that way you don't have to use a bunch of bandwidth to put that all on your thing, and also
271490	277950	so that way you don't have to store it yourself. For most people, unless you really want the
277950	282210	blockchain, you could just go ahead and click simple mode, and it's going to take you and
282210	286290	connect. It's going to find one of those and connect automatically the one that's going to
286290	291830	be the closest to you. So I'm going to go ahead and click simple mode, and it's going to
291830	297570	this thing. It's like, okay, are you sure? Just be aware. Just be aware. This is not the most
297570	302150	private way that you can do it. Remote nodes could compromise some privacy. Let me go ahead
302150	308970	and make this a little bit bigger. Wonderful. So we've made the window bigger, but we haven't
308970	314670	scaled the text at all. I don't know if this is readable on the YouTube. I don't suspect that it
314670	323330	is. Okay. We're just going to go ahead and move forward from here. You can ignore this. I'm going
323330	327730	to go to advanced mode because I already have a local remote node set up that I'm going to connect
327730	332810	to at my own place. But we're just going to pretend that you pressed simple mode and you
332810	337390	pressed yes, I understand these consequences, and then you're going to come to here. Create new
337390	341510	wallet. Create new wallet from hardware, open a wallet file, or restore wallet from keys and
341510	345690	So these are pretty self-explanatory. Create a new wallet is what we're going to go through in
345690	350410	just a second. That is going to let you create a brand new wallet. Hooray! Create a new wallet
350410	353990	from hardware. I'm certain if you've been in the blockchain space for any length of time,
353990	359710	you've probably heard the names Trezor and Ledger. These are hardware wallets that you can get. And
359710	365130	they keep the keys on the hardware device. And in theory, they're supposed to be hard to extract,
365130	370090	if not impossible. And it helps so that way, if you do have a virus on your computer,
370090	374230	if you have any of these things, they really can't steal your Monero because all the keys
374230	379350	are stored on the hardware and you need the hardware to be connected in order to send a
379350	383070	transaction. So if you have access to one of those devices, you have one of those devices,
383070	388690	or you want an extra layer of security, Monero does work with both Trezor and Ledger.
388690	393330	So this is how you would make a new wallet if you were connecting it with the hardware.
393450	398710	Open a wallet from file. So after you make a new wallet, it gets put on your file system. And so
398710	403310	if you have multiple wallets for whatever reason, your wife has a wallet, your husband has a wallet,
403310	407730	your dog has a wallet, and all of you guys have separate bank accounts, so to speak, right? You
407730	412790	can click on this and navigate between wallets, if you have multiple ones on the computer.
413330	417090	Restoring a wallet from keys or mnemonic seed. In just a second, when we create a new wallet,
417090	421590	we're going to see what a seed looks like. It's basically 25 words that we're going to need to
421590	427030	write down. And if your computer dies, if your phone dies, wherever the wallet is stored,
427030	434190	you will be able to get your Monero by clicking on this option and typing those seeds in.
435050	440830	And I will greatly stress the importance of seeds here in just a minute. They're extremely,
440830	445810	extremely important. Is this bugging people that you want it more in the middle? I mean,
445810	449810	yeah, we'll put it more in the middle. I don't know. Maybe some people are annoyed by that.
450810	454070	So we're just going to go ahead. You can go ahead and ignore these ones right here. Change
454070	458890	you back to simple, advanced, whatever. And change language is pretty self-explanatory.
458890	463350	So we're going to go and create a new wallet. Okay. First thing we're going to find out.
463490	469530	So on this virtual machine, I just named it funsies just because this is for funsies.
470270	474790	And there is a wallet location. So this is where your wallet is actually going to be stored. You
474790	480030	can click browse and change where that's going to be. Okay. So you can give your wallet a name.
480030	486610	I'm going to call this Defcon new. You can name it whatever you want. Now we get to this thing,
486610	494410	the mnemonic seed. And this is the single most important thing that you're going to do when you
494410	503490	make a new wallet. You need to write these words down. You need to get out a pencil and a paper,
503490	512070	10 papers, and write these words down. Okay. If you lose your wallet, meaning your computer dies,
512070	516390	or it explodes, your house catches fire, and you don't get to save anything, you know,
516390	524150	anything could happen. If you lose your computer, if you lose your wallet, but you have these words,
524150	531670	then you have your Monero. If you lose your wallet and you do not have these words,
531670	538590	then you have lost your Monero and nobody can help you get them back. These words are like a
538590	544950	human readable representation of your private key. So if you do not have these words, you don't
544950	552770	have your Monero. And further, if somebody else sees these words, they now have your Monero. Your
552770	558470	wallet has no way to distinguish between whether that person is the actual owner of the wallet or
558470	562950	not. All they know is, okay, they have access to these words, so they can spend the Monero.
562970	566990	If you have these words, you can spend your Monero. So you need to write them down. It's
566990	571510	not recommended to put them digitally, because what happens if your computer gets hacked or
571510	576030	any number of things, right? And it's important that you have more than one of these in a very
576030	580950	safe place, because if you only have one paper copy and it gets burned up, or something happens
580950	587410	to it, or there's a flood, then you have lost your Monero. You must, must write this down.
587410	595450	Do it now. Do it now. And for this particular presentation, I mean, I just pressed brand new,
595450	599970	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.
599970	606370	It's a new set. It's just going to be different every time. So I would not recommend writing
606370	611870	these down. I also would not recommend using the wallet with this seed for anything, because now
611870	617070	this is available to the public. This is available on YouTube, on Twitch. And if anyone's writing
617070	620530	this down, hoping, okay, Diego's going to be sending money to this wallet to prove things,
620530	624610	and I'll just steal it, because I have the seed, ha-ha, you're mistaken. I have other wallets set
624610	631210	up that we're going to do that for. So write this down. Don't send to this one. Don't send to this
631210	638650	one. Wallet restore height. What does this mean? This is basically... so Monero's chain is really,
638650	645110	really big. I told you it's several, several gigabytes large. And if you make a brand new
645110	651130	wallet, right, if you make a brand new wallet, why would you want to scan the whole chain to
651130	654990	see if you have any transactions? Because in theory, if it's a new wallet, you have no previous
654990	659410	transactions. If you're restoring a wallet, then maybe it's important. But for a brand new wallet,
659410	666510	it's not important. So we're telling it, okay, start 2 million blocks up. Don't start at block
666510	673210	zero. Start 2 million blocks up. And the GUI's going to chew something to you relatively close.
673210	678670	So we're going to go ahead and click next here. This is where you're going to put your password.
678790	683650	Okay. If you forget your password, but you have your seed, then you have your Monero. If you
683650	688610	forget your password and you don't have your seed, you don't have your Monero. So the seed is the
688610	693110	most important thing. Write it down. The password is to make sure that anyone who gets access to
693110	698130	your computer that maybe shouldn't have access to your computer can't send your Monero away or
698130	701570	something. Because it doesn't require you to put in your seed every time. And we'll see that in
701570	707690	just a moment. So I'm going to go ahead and click next. You can put no password here. I would not
707690	715710	recommend it. But for these purposes, this is what I'm going to do. I do have a bootstrap node.
715710	720290	So just one second. This should have been already filled in. But it's not. Which is a little
720290	732890	annoying. Just one second. This is where I have put my temporary node. So now you all know where
732890	740070	that is. Fantastic. Uh-oh. No. Connect to a remote. Do it here. Do it here. Okay. Create wallet.
740630	745470	So here's where you would be putting in your password if you had one. I just press okay
745470	749710	because I didn't put a password for this. And you come to this screen. And you see okay. Now we're
749710	754690	scanning. But it's not from the beginning of the blockchain. It's from block 2 million. And bam.
754690	759770	It's done. Super quick. This would have taken a long time. Hours, probably, if it was scanning
759770	764950	from the beginning. But once it scans once, it doesn't have to do it again. So if you do scan
764950	770110	from the beginning, then after it's gone through those hours, the next time you open your wallet,
770110	775470	it won't have to do that process every single time. It's just that once. So we've got several
775470	779950	screens over here. The GUI starts you out on the send screen. And as you can see, we're gonna put
779950	785090	the address that you want to send to, the amount that you want to send, your transaction priority,
785090	788510	which determines the fee that you give the miners. The higher the fee, the more likely you're gonna
788510	794110	get in, unless the blocks aren't super full. In which case, pretty much everybody's gonna get in.
794110	800510	So if we click on this, you can see slow, normal, fast, fastest. These are how much fee you can put.
801110	803590	Monero also has this cool thing where you can add a description.
805070	809130	Just for your personal thing. So when you send a transaction, you're like, oh, I sent this to
809130	814230	my cousin for this reason. And so you just know what everything's for. We also have an address book.
814230	819210	So if you use, you know, if you're paying an employee and you do it consistently every month,
819210	822730	you can save their address here. So you don't have to ask them for it every time. Why would we want
822730	826470	to do that? Well, if you've never seen a Monero address before, let's go to the receive screen.
828310	833490	And this address is very, very long. You can't see it here because it's truncated. So actually,
833490	842250	let's go ahead and open up a notepad. Boom. This is what it looks like. Okay. This is a
842250	848290	Monero address. It's very long. It's very, very, very long. So you can't call your grandma and be
848290	854850	like, okay, grandma, here it is. It's four, five, lowercase p, lowercase h, lowercase p,
854850	858810	uppercase L. You can see how that's going to be prone to errors and stuff. So you really got to
858810	865190	copy and paste it in every time. You got to ask for it. So the addresses, saved addresses on your
865190	870490	address book is going to help with that. You also have a QR code. This is the same thing as this. So
870490	876510	if you scan this QR code, we do have mobile wallets available. Cake wallet for iOS and Android and
876510	883750	Monero for Android as well. You can go ahead and scan that. And send to it rather quickly.
884010	887610	Transactions is going to be a list of transactions. Because this is a brand new wallet,
887610	891070	we don't have anything here yet. And I'll show you one of the other wallets that I've made here
891070	898250	pretty quick. Advanced for the most part. We're not going to cover those. It's outside of the
898250	903090	scope. I've only got about 15 minutes left. And we still need to do some things. But you can mine
903090	906510	from this. The only one we are going to touch on is this prove and check. This is how we're
906510	909950	going to prove a transaction. And we're going to get to that in just a minute. Settings is where
909950	913550	you adjust some things in the wallet. And you can go ahead and click around those and see for
913550	917910	yourself. Accounts. We're not going to go ahead and worry about accounts for now. But there's
917910	922750	just this idea that you can generate multiple subaddresses, which are addresses that link back
922750	928230	to this one address. So, you can make multiple subaddresses that all go down to this one thing.
928230	931850	And you don't have to have new seeds or make new wallets or anything like that. You can also do
931850	939950	this from the receive screen. Create new address. What is this? This is subaddress 1. And Monero
939950	945450	addresses start with 4. Subaddresses start with 8. And you see that the QR code changes every time
946110	952470	to match the thing. Okay. So, this is the new wallet. We're gonna go ahead and push this aside
953070	957030	because we know the seed for this wallet. The seed is for everybody. So, we're gonna go ahead
957030	963590	and push this aside. And I'm going to grab some other wallets and bring them onto the screen.
965730	971030	And here, we have Defcon send and Defcon receive. Let's go ahead and put this this way.
971990	977670	Both of these, you don't know the seed for them. That's the point. But they do have some Monero on
977670	982830	them. This one has three Monero on it. This one has one Monero. And we're gonna go through a
982830	988230	couple of the flows. Before I move on, let's see if there's any questions. Blah, blah, blah.
989370	993110	What about JavaScript? What about JavaScript? I don't understand.
995490	1003430	Okay. I think we're good. All righty. So, as we can probably tell by the names of the wallet,
1003430	1008150	Defcon send is going to be sending to Defcon receive. So, how we're gonna do that, it's as
1008150	1012710	simple as this. On the wallet that you want to receive from. So, if you are the recipient of
1012710	1017390	money, you're going to go to receive. You're going to copy this. If you press this icon,
1017390	1022150	it copies the address to clipboard. Or you can give them this QR code, which you can save as an
1022150	1027110	image or also copy that to clipboard. And on the wallet that's send, if you're the sender,
1027110	1033450	you're gonna go ahead and paste this in here. Now, you want to double check the address. Because
1033450	1041710	there are there is malware out there that will replace the address in your clipboard with their
1041710	1046930	own. And you want to double check that. You want to make sure that this address didn't get replaced.
1046930	1055390	You don't have to do the whole thing. So, in this case, we see 47BXR3PB. And if we look here
1055390	1065570	at the recipient address, we indeed see 47BXR3PBMKWI. And this truncates it, but it also
1065570	1075650	has some at the end. You know, the last four are LQCW. If you want to be 100% sure that you're
1075650	1081430	the correct address, you verify the entire thing. Most people, like, if you just do the first four
1081430	1086070	and the last four, that's probably too little. Because it may be easy for somebody to generate
1086070	1092730	something that looks similar. Verifying any of them is better than nothing. But, you know,
1092730	1098930	verifying the first maybe 10, 16, the last 10, 16, it's the more you verify, the harder it is
1098930	1102590	for somebody to kind of cheat you and make it so that way you don't know what's going on.
1102590	1106890	So we've went ahead and put this in here. We can go ahead and add this to our address
1107710	1111450	if we want to. I'm not going to go and do that, but you can go ahead and do that. If you click
1111450	1115230	this, it'll take you to the address book. You know what? I am going to go ahead and do that.
1115230	1122750	I'm going to add an address. And this is Diego. He's so cool. All right. So that's what this is
1122750	1127610	added as. So now from the address book, I can actually click on this and it will autofill
1127610	1132850	on the address here. It will autofill that. So I'm going to go ahead and send Def Con receive
1133770	1140890	one Monero. For the most part, we're just going to like automatic on transaction priority is going
1140890	1146050	to be okay for 99% of the time. I don't recommend touching this unless you know what you're doing.
1146150	1149810	Advanced options, we don't really need any of this, so let's not worry about it.
1149910	1153690	So now it's creating the transaction. It's building the ring signature,
1153690	1157350	getting the cryptography ready, all this stuff. It's like, okay, this is where you're sending it
1157350	1162370	to. This is the amount. This is the fee. Here's the ring size. Here's the description. Does all
1162370	1168110	this sound good? Yes. Okay. It's going to prompt you to put in your password, which if we had one,
1168110	1173110	I'd put it, but we don't, so I'm just going to press okay. All right. Monero sent successfully,
1173110	1176110	is what this says, because I think it's a little too small and blurry for everybody to see.
1176270	1182030	Monero sent successfully. And then it's got this huge long string of alphanumeric string.
1182070	1185170	This is your transaction ID, and we're going to come back to this when we prove transactions.
1185170	1191910	You can go to a Monero block explorer and put this in there, and we can see when it comes out.
1192590	1200150	Okay. So I just sent one Monero, and if we go to transactions, we can see... you've seen here
1200150	1204250	on the transaction screen, you can see that I have put some Monero onto this wallet for
1204250	1214370	these purposes. These are the past transactions. I sent one XMR 28 seconds ago to this address.
1214370	1219450	And boom! Oh, wait, no, this is the one that we have already that was already on here.
1219590	1224550	If we click on transactions, you'll see... ha-ha! We do have one. This was the one that was already
1224550	1229230	on here, but this was 46 seconds ago. The reason it's not showing up here is because it needs to
1229230	1233590	be included in a block first. If you don't understand how a blockchain works, transactions
1233590	1238230	need to be included in blocks, which then need to be mined and da-da-da-da-da. There's a lot of
1238230	1241730	great resources out there that talk about how a blockchain works from the ground up. I would
1241730	1247150	recommend giving it a look. But although that isn't super important right now, Monero's block
1247150	1252730	time is two minutes, which means that the average amount of time it takes to find one block is two
1252730	1258150	minutes. So this will be about two minutes, but it may be more, it may be less. It depends on the
1258150	1265450	luck of the miners before this is going to start showing up here. So that is the send and receive
1265450	1270370	flow. It's really not difficult. If you want to be the sender, you just got to know the address,
1270370	1273830	know how much you're going to send to them. You can send all of your Monero there if you want
1273830	1279270	and set a fee, which automatic is going to be okay most of the time. If you're the receiver,
1279270	1284290	you're going to either copy the address and give it to them, double check that it wasn't replaced,
1285050	1289610	or they can scan this QR code, which you can save as an image and send to them or whatever
1289610	1293990	the case may be. In all cases, you're going to want to check to make sure that the alphanumeric
1293990	1298590	string was not changed and the QR code was not changed. You just want to make sure that it's
1298590	1301790	actually going to go where you want it to go. Because if you accidentally send to the wrong
1301790	1307330	address, you have no way of getting that money back. There's nobody to call. There's no customer
1307330	1311690	service. There's nobody who can get it for you. It's all cryptographically enforced and nobody
1311690	1317310	can save you. So we're going to go ahead and prove a transaction really fast. And I hope this goes
1317310	1323670	well. I hope this goes okay. This is the reason why I put a previous transaction of one because
1323670	1328890	I don't want to wait for this one to come into a block before we start proving. So this one was
1328890	1336990	sent three hours ago. And we're going to prove that this DEFCON send did in fact send to this
1336990	1341750	DEFCON receive. So if you imagine that DEFCON receive is a merchant and DEFCON send, they
1341750	1346590	purchased something in Monero from that merchant and the merchant says, oh, well, I didn't receive
1346590	1352970	this Monero. I didn't get it. You can prove that you did. So let's go ahead and go to advanced
1352970	1361190	and proof check. And here advanced proof check as well. So we need the transaction ID. So actually,
1361190	1367190	let's go back to transactions. This was the one that I sent prior. And if we click on this,
1367190	1370850	we see that there's details that drop down. Here's the transaction ID. You just find what's
1370850	1375970	labeled transaction ID. And we just left click on it and it automatically copies it to clipboard.
1375970	1381790	Great. So we're going to go to advanced proof check and paste in this transaction ID.
1382470	1387830	Let's just double check that it's correct. A89BB64 blah, blah, blah, blah, blah. Yeah.
1387830	1394490	It's all good. The address. We have to know what address we sent to. Once again, if you go to
1394490	1401750	transactions, it has in the data about the transaction at the bottom, it has the address
1401750	1410510	to send to. It's this one right here. So we're going to go ahead and copy this and put it
1411950	1416330	in this proof check. Now, you can put an optional message here. And this is just
1416930	1421630	an extra kind of fail safe. But the other person has to put this exact same message,
1421630	1424550	otherwise it's not going to check correctly. So we're going to go ahead and put
1425450	1428350	Defcon as the message here. Now, we're going to click generate.
1429910	1435330	Now, once we click generate, it gives me this payment proof. This thing that starts with out
1435330	1441270	proof V1 something, something. So we're going to copy this, double tap to copy the clipboard. And
1441270	1447110	we would send this to the recipient. We would send this to them and say, this is the proof.
1447110	1451990	This is the proof. Okay. Now, I'm the merchant. I want to say, okay, Diego says he sent it to me.
1452450	1456230	For some reason, I'm not seeing it or I don't know. Okay. Let's go ahead and check this out.
1456230	1461710	We're going to scroll down to the second part, check a transaction. The first thing we're going
1461710	1465270	to do, we're going to paste in the signature. The out proof something, something, something that it
1465270	1470990	gave to me. Okay. The transaction ID. I'm just going to copy it from here. But the transaction
1470990	1475710	ID is a public thing. It's known to everybody. So sharing this or you can get it from the block
1475710	1479850	explorer or whatever, it's not a big deal. I'm going to put that here as well. The address,
1479850	1484650	I know what my address is. It's the address that I told them to send to me on. Oh, by the way,
1484650	1488630	the other one has popped up now. So we have one, not two. And the message. If we put an
1488630	1492590	optional message, once again, it has to be the exact same thing. So I have to put Defcon
1492590	1499990	or whatever it is that they put. And we're going to click check. And it says, okay, this address,
1499990	1505230	if it's too small for you guys to read, it says this address received one Monero with 107
1505910	1512830	confirmations. This says you did indeed receive one Monero and there is 107 blocks on top of it.
1512830	1516050	So you can look 107 blocks back and that's where you're going to find it.
1516170	1520430	If any of these things is incorrect, so if we put an incorrect here and we click check,
1520430	1523690	it's a bad signature. That's what it's going to say. It's going to say, nope, this isn't real,
1523690	1527350	this isn't correct. So if the signature is not right or the address is not right or the
1527350	1531710	transaction ID is not right, all of that stuff is going to be incorrect. It's only when everything
1531710	1538170	matches 100%, which because everything is cryptographically generated, there is zero
1538170	1542490	chance that if you put in everything correctly, the transaction ID, the address and the message
1542490	1548930	that it will say bad. It's only if there's a big flaw in the software. Because all of the
1548930	1552090	cryptography checks out, it's mathematically enforced, there's no way for somebody to...
1553710	1560070	there's no way for a merchant to cheat you out and say, no, I didn't receive it. When you're
1560070	1563850	watching them put in the ID, the address, the message and the signature and you verify that
1563850	1570230	everything is correct, there's no way that this will be incorrect. So the address received one
1570230	1579930	Monero. Great. Awesome. So that's how to prove and check a transaction. Not all wallets. So
1579930	1586510	most mobile wallets and stuff come with this capability. So if you do need to prove or check
1586630	1592010	a transaction, then, you know, where the ecosystem is still developing and blah, blah, blah. But
1592010	1596370	there is a way to do it. There is a way to do it. And that's what I just showed you right here.
1596370	1601370	That's the basics of the Monero wallet. As we're closing in, I got four minutes. That's the basics
1601370	1609970	of Monero wallet and how it works. The last thing I'm gonna talk with you about is that this one
1609970	1616190	Monero that I received, it's not yet spendable. You can see it says confirmations, 6 out of 10.
1616310	1621650	The Monero protocol kind of has it so you have to wait 10 blocks before you can spend it again.
1621650	1626130	And that's just a safety precaution to make sure that every organization doesn't ruin
1626870	1630510	your transaction. And if that's a little technical, then I apologize. I don't have
1630510	1635690	time to get into that at the moment. So are there any questions from anywhere?
1637090	1642390	Can you please make the wallet a little bigger? Thanks. I'm sorry. I wish I could. But as you can
1642390	1653190	see, when I make it bigger, the white space gets bigger. And the rest of the stuff doesn't. It's
1653190	1660310	because the DPI of my monitor is too high, unfortunately. I don't know if there is a way
1660310	1668870	to increase the size. Let's check it out. Settings. Interface. There's no way to change the
1668870	1675430	size in there. You'd have to change it in the window settings or something. No, there's currently
1675430	1681610	no way for us to make the interface bigger. That's something that should probably be there.
1681610	1687270	We can talk. Maybe I'm just an idiot and it really is there and I just don't know.
1687590	1693790	Yeah. So I do apologize for everybody. I do apologize, everybody, that the wallet
1694310	1700690	transactions are so small. I hope you're able to squint and get a little bit of an idea. At the
1700690	1705890	very least, where the general things are supposed to go. It's pretty self-explanatory where all the
1705890	1712690	things are very neatly labeled. So hopefully this was marginally useful. If you get nothing else
1712690	1720010	from this talk because everything is too small, write down your seed. Write down your seed.
1720090	1724970	Remember that thing at the beginning? Those 25 words? Write them down. Write down your seed.
1724970	1729910	Write it down. If you have your seed, you have your Monero. If you don't have your seed,
1729910	1735730	you don't have your Monero. Write it down. And that's basically it for me, guys.
1735890	1746030	Hope it was useful. Glad you all came. This will be available... you know, I'll probably record
1747410	1753210	myself doing this a second time where you can actually see things if they're not too small.
1753650	1758750	And we'll try to make that available on the Monero community YouTube channel that you're watching this
1758750	1762930	on. So if you are still confused because you couldn't see anything, then be watching out for
1762930	1766490	that. Hopefully within a week or so we can get that done and get that uploaded.
1768770	1775450	That's it for me, ladies and gentlemen. We've got a meme competition coming up here fairly soon.
1775450	1780390	I'm going to stop sharing my screen so you can see my lovely face. Hey, this is the guy that's
1780390	1783470	been talking to you this whole time. Diego Sauzar. Rebrar.
