Hey, is this thing on? Hello everyone and welcome. Hey Dexter Starboard and C Grover and Mr. Certainly over in the Discord chat and hey everyone over on YouTube. Hey John O. Nice to see you all. Yeah, hey I'm back. I flew all the way to the East Coast and back here and boy are my arms tired. But seriously folks, it's great to be back. Great to have you all here. I'm excited about our new product pick of the week this week. Hey doctor, nice to see you. I'm gonna have a sip of delicious ice water. Mm, boy that's good. Refreshing. So let's do this, shall we? We're back, thanks for letting me get away for a week. It was nice to have a little bit of a vacation and now we're gonna dive into it. So, how does this thing work? If I remember correctly, what I'm gonna do is let you know that if you wanna watch the show from inside the product page, you're gonna get 50% off discount during the live stream. All you have to do is head over here to this QR code or to this URL right here and you will jump on over to the product page. You can watch this show from inside the product page and that's pretty darn cool but you can get that 50% off on this product this week. It's a discount that's only good during the live stream so be sure if you're interested in it to load up, I think you can get a maximum of 10 of them during this special pricing, no reseller prices or no reseller sales just for the people, the people who want this product. But before we go any further, why don't we find out a little bit about the product from Lady Aida. So I'm gonna have Lady Aida take it away. Niyuki, one by four QT. So, how do I explain it? Basically, you wanna add mechanical key to your project. You don't wanna time, you maybe only want four key switches. You want new pixels with them but you don't wanna do all of the like the wiring for it. You want to have it over I squared C and maybe also wanna chain it with more of them, right? You can actually connect multiple of these. So this is a way of very quickly adding four mechanical keys with new pixels to any board. It has a C-style microcontroller on the underside which does the I squared C to new pixel and key switch conversion. I've got my QT Pi here. So it's just something that has an I squared C connection and this is running Arduino but it works also with circuit Python just fine or Python to use with a Raspberry Pi or what have you. And each key has a neopixel underneath and this demo just when you press it, it does a little neopixel color swirl. So that's the demo and you can have multiple keys pressed at a time. They have Kale sockets. So these are socketed so you can use any Cherry MX compatible key. This is I think Cherry black or Kale black, I don't remember. And then of course you put your favorite key caps. Maybe it's a little kitten key cap or maybe it's these translucent ones so you get the glow through. And you basically have a very easy way to add four key caps. Okay, so key switches to your project and then the I squared C comes in. This is the chip that handles all of the key presses and the neopixel stuff. And there's address jumpers here so you can close these which allow you to connect multiple boards to one I squared C port. So you can have up to 16 of these on one I squared C bus. So if you're not enough to make a full 108 key board we're making like a macro pad, right?  You just plug in your favorite mechanical key and you have plenty of mounting hole options. So you've got four mounting holes on the corner. You can also plug into a breadboard if you don't want to use these cables for easy purporting. I just think it's like a fun way to get mechanical keys into your project without any key matrix handling without neopixel handling. It's all done for you. Hey, wrong button. Yes, so the question, the important question that doctor asked in the chat was did Lady Aida grow an extra hand in that video? I think that was PT's hand visible there but I thought the exact same thing. How about that? So I'm gonna go grab one of these myself and then we'll talk about this. Am I really muted? That was weird. Little thingy looked like it was going. All right, let's try that again. The product pick of the week this week is the NeoKey 1x4 QT, I squared C mechanical key switch board. It has four sockets for placing your mechanical key switches and it has four underlit neopixels. So you can plug this into any board that has I squared C and particularly convenient when you have STEMI QT connectors and you can plug in your key switches to the board. So there you can see I've got a set of four key switches on there, a couple of red ones linear, a couple of black ones, a little tougher to push and some different key caps on there. So what I wanna do is jump to the overhead here and we can take a look at this in action. So here you can see I've got a little QT pie and I've plugged in one set of our NeoKey 1x4 to there but since we have address jumpers for I squared C there I can in this case change the I squared C address for a second one and plug that in as well. So I'm gonna go ahead and just plug that in using a little STEMI QT cable and then I'll reset the board there and those should restart and then we'll be able to use all eight of these keys. So here you can see I'm not actually doing anything other than changing NeoPixel colors when I press but you could set these up of course as HID, as general IO, as MIDI, there's a lot of uses for these and in this case I have I think a maximum of maybe it's eight of these that we can plug in or 16 I think lady had said that. So you could get a pretty big array of these you can mount them to something using the little mounting holes on there you can also put these into a Perf board or a breadboard using the header cable or a header pins if you wanna solder those in. Now to show something a little more fleshed out here I've got a little demo board that I've put together and so what I have here are this is the NeoKey 1x4 QT plugged in over I squared C to a feather board and then I also have some of our little rotary breakouts here little rotary trinky breakouts and so what you can see here is I have some key caps that are relegendable which means the little plastic tops pop off and you can print something out and put a label or a sticker under there. So I've set this up to be a little keyboard shortcut board for use inside of Photoshop. So as you can see here I'm gonna go ahead and switch over to Photoshop which some things were acting really slow when I was trying to screen capture it and show it to you so we'll see if that still works. So right now you can see I have a little eyedropper tool picked there and if I press this first button I switch back over to a brush switch to the eyedropper this is the eraser tool and here is a gradient tool so if I go to the brush here I've also set up my little rotary encoder to be a brush size normally in Photoshop you can pick that with a slider but you gotta go click on it or you can use the bracket keys to go bigger and smaller but now I have a little rotary encoder and I can also change the softness and hardness of that brush. So I can go in here and paint a little bit and then let's say I wanna switch to blue I'm gonna hit my eyedropper, grab blue switch over here and start painting in oh did I get blue? Doesn't look like I did. Oh that's weird. What's happening with the eyedropper? Okay eyedropper, oh I'm on an invisible layer how about that? Let's turn that back on, okay. That's better, I was in a funny mode. Okay so here you can see I can paint in blue I can hit my eyedropper, switch over to this pink switch to a different brush maybe change the size of that paint in there a little bit and we can go in a race so I'll switch over to that eraser with this little shortcut and then we can start erasing.  So that's one use of this is just as a little shortcut keyboard and I'll show you how that works it's actually really straightforward in whatever app you're using in this case Photoshop there will usually be some keyboard shortcuts in this case B goes to the brush I goes to the eyedropper tool E goes to the eraser and so on. So if we look at the code here inside of circuit python let me switch, put on my glasses in this case I'll go over the more standard case in a second but I'll just show you in this case the key things being I'm actually using the debouncer in this case and when I look at what happens during the main loop of the program I have things like if key zero rose which is a pull down so it rises when we press it. When that voltage rises we print to the serial brush just so I know that I did the right thing while I'm debugging and then I'm changing the neopixel color I'm setting all of them to white except for the current one which I'm latching to a color that's unique for that button and then I'm sending this key code this is using our USB HID key code commands to send a key code B and we have I set up for eyedropper E for eraser, G for gradient and so on. Now let's look at the sort of standard example so I'm gonna bring this back unlike some of the typical ways that you'll use buttons plugged into GPIO this is using our seesaw over I squared C so a lot of the heavy lifting is done for you by the seesaw library so here you can see in circuit Python what's going on I import the board for pin definitions I import this Adafruit NeoKey library and from that I'm grabbing the one by four so we have room to add other specific types of boards and I'm importing that object as NeoKey one by four we set up the I squared C bus and then since I'm using two of these boards I'll actually create two different NeoKey objects I just call them NeoKey and NeoKey two and those have the same command which uses the NeoKey one by four and it specifies this is on the I squared C bus and the address so one of them is at address 30 the other is at address 31 because I soldered that jumper under there and then the main loop of this is actually pretty simple let me go ahead and open up a serial port so we can see what's going on I'm gonna unplug the other keyboard so we hopefully grab the correct one okay so what happens now is when I press a key the seesaw library this is the only command you need to know if you wanna check one of these keys it's just NeoKey and the value of it at the address that it is so NeoKey zero, one, two and three or NeoKey two, zero, one, two and three those are the buttons and those values are true when they get pressed otherwise they're false so when I press this first button it says button A was pressed it changes my NeoKey color to red and then when I release it it changes the NeoKey color back to blue and then I have those set up to do a few different colors and names when I press them and then my second row here is just called button A two B two C two D two and you can press these all at the same time if you want it'll register them all it's a little hard to read that but you can see here A two is pressed as is button D and those will just scroll by there you can use this with the debouncer or other more sophisticated methods if you want but just to get you started it's really straightforward to just simply ask using seesaw and this NeoKey library you can just check for the value of a button to see if it's pressed or if it's not pressed let's see for, let me check and see if there's any questions over in Discord here oh yeah you know what let me show the page here which I forgot to show you so here is the page for this board you can see you got some nice pictures there of the backside front side of the board you can see this uses these nice little kale sockets which allow you to just press and remove no soldering required in fact you can use this entire board without any soldering and if you're using something like this cutie pie here since these both have the stem of QT cable you can simply plug them in with one of the different stem of QT wires that we have these are quick compatible wires and they come in a few different lengths so this is ready to go with zero soldering which is terrific you can of course solder we have all those same iSquared C pins broken out here on the board and so depending on your needs you've got a bunch of different options for how to set this up the key switches for this are any Cherry MX compatibles so that's Gateron, kale, Cherry MX we have a bunch of different kale box switches available on the site here too and in the clicky, tactile and a couple of linear types but you may have others that you like and as well we have a bunch of different keycaps so since we've got the Neopixel under there shining through you probably want to try something that's either translucent or windowed or has a silicone kiddie paw like that one there super cute and we sell a few of those as well on the AdFruit Store if I refresh this site right now you should see hey we have 55 of them in stock and they're half priced so $4.98 you can bring one home today or 10 if you want if my math serves me right that'll be $49.80 and let's see the library for using this is on GitHub I don't believe we have this in the bundle yet in the circuit python bundle we're working on there'll be a guide coming out that'll point you at all these things but if you get one now and you want to get started you'll go to GitHub and just search in the Adafruit GitHub for NeoKey and there you can see adafruit underscore circuit python underscore NeoKey that's where the library is and clicking on here you can download the whole thing so you just go to this green code button download zip then you'll have everything you need and what you'll place in your library folder of your circuit python capable microcontroller like the little cutie pie I have here is this Adafruit NeoKey folder that contains the library you need and in the future we may add more more boards to this right now the NeoKey one by four is the only one in there and you've got a folder of the example code so if you go to the examples and try this code here it's really similar to what I did with this basic example other than changing the LED behavior a little bit in the colors and then adding the second set so we can continue to add these on and get a pretty interesting board you can also create some interesting shapes right if you've got some unusual needs for your board you can lay them out in ways other than just sort of a simple grid or something that you could place on a perf board you could also turn these at diagonals you could create a letter Z I don't know why but you can or a V or an A so let's see the comment here over in Discord doctor says I can't afford switches for all my MX compatible things yeah when you get a lot of these going you start to pile up on the switches and the keycaps question can you get the value of the keys as a number so key zero is one key two is two and so on so if you pressed one and four the sum would be nine and you know two keys are down at the same time yes you could code that for sure you could set up some conditionals you could have variables or lists that are adjusted depending on which keys are currently pressed so there's probably a few different ways that you could do that but yeah it knows that multiples are down and you can query that you can also use things like the debouncer library which can go and check those as well without the need for pauses and things to avoid the key repeats or you can use little simple state variables that you flip a state of something when it's pressed so for sure you can do some neat sophisticated stuff so that you can do big corded macros and change the behavior based on modifier keys so you could have one of these act as a shift key or a control key, command, that sort of thing for sure as built to code asks can you string up you can string up 16 neat does Adafruit sell a larger four by three format version it is coming as on the way we have a four by three macro pad in the works if you check the desk of lady Ada videos on YouTube you'll see some progress being made on that over the past few weeks and including some really exciting work on the keypad library that will read matrix keypads and vector keypads using diode matrix layouts really quickly it's native C code that's running in the library even though you're using circuit Python so it's lickety-split I think it pulls the whole thing in three milliseconds, nanoseconds, picoseconds something small I can't remember what but it's fast was the thing and I think that's about it yeah so thank you for coming in and stopping by asking your questions this let me go to the full view of that for a second there this is what you'll get right here with the Neo key one by four QT I squared C mechanical key switch breakout key strip it's not exactly its official name but that's gonna do it so let's put this up on the big board that's our product pick of the week it is the one by four Neo key the product pick of the week is the Neo key one by four QT I squared C mechanical key switch breakout with Neo pixels and socketed key switches so I'll go ahead and place that on my new product pick of the week board of goodness and that's gonna do it so thanks everyone for stopping by and if you have other questions put them in the discord chat put them on over in the YouTube chat and I will see you next time be sure to stop by tomorrow for lots of different live streams on Adafruit including show and tell and ask an engineer and the 3D hangouts in the morning with the Ruiz brothers and I'll be doing my workshop show on Thursday so come on by for that I believe Scott is still off so no Friday deep dive with Scott but that'll be returning pretty soon I think maybe the following week so that's gonna do it for today I'm JP and I will see you next time bye bye


Enzamin is a natural product derived from the bark of the Chinese medicinal plant in Zafrotinensis. It has been shown to have beneficial effects on obesity-related metabolic disorders such as hyperglycemia, hyperlipidemia, and insulin resistance in obese Db, Db mice. Enzamin treatment reduced fasting plasma glucose, total cholesterol, and triglycerides, while maintaining normal body weight and body fat composition. Additionally, it improved insulin sensitivity and glucose tolerance, which suggests that Enzamin may be a promising therapeutic option for treating obesity-related metabolic disorders.

So, back to my words about Jagdish Babu, who was an important component of, was an important collaborator for Italo project. He wrote a lot of the code, both the Java side as well as he worked on the Solidity side and he, and people are using his code even today.  But back to Jagdish Babu, unfortunately he passed away and I want to recognize and memorialize him in this meeting just to say how lucky we were to have his presence in this, in our collaboration and how much he contributed to this enterprise to Italo. Thank you Jaga, wherever you are. And with that, I now introduce Dr. Franklin Knoll, who is the president of Knoll Historical Consulting and he's going to talk to us about a novel concept probably created by Andrei Lipkin and others, but he will introduce the concept and go on from there. Let's hear him. I'm sorry that it's taken seven minutes for us to get started, but we had to go through these important announcements. Thank you again, doctor. Let's hear from you, maybe a couple of words about what Knoll, Knoll Historical Consulting does and let's take it from there. Thank you. Well, hi everybody and thanks for inviting me to give a presentation. I am, like I said, Knoll, president of Knoll Historical Consulting and our major focus is monetary history, the technology of money. We talk to or consult with mainly the US Treasury, sometimes the Fed and private groups or private companies who are dealing with, let's say banknotes, maybe monetary policy or these days it's all about crypto. So we're all busy in that field. And so that's where I'm basically at now. I have colleagues, one is Andre Lipkin, who will talk about a little bit later and Nick Sharer and you're focusing Nick does heritage management. Say if you want a history of your company written or want to do some marketing based on your history, he's the guy Andre deals with hybrid banknotes and other blockchain issues dealing with money and banknotes. And I'm the historian and this is where it's all started. So I'm not an economist. I am a historian and I approach all these matters from a slightly different perspective than an economist does. And so let's just start talking about hybrid banknotes and I'll turn my camera off and we can focus on the slides. Okay, there we go. So what we're really talking about is the future of payments. And as you know, you are kind of in a transition now between cash and digital means and cash is not going to go anywhere, though many people expect in the crypto world think cash is going to disappear the day after tomorrow. That's probably not going to happen. People have been forecasting or predicting the end of cash since the late 1960s and they'll hear. So it's going to probably be around for another generation. And so what we need to start thinking about is some kind of transitional device, something that will take us from everybody using cash until we all start using digital platforms. Or using our phones or some other digital platform. And what makes the most sense for me and for many others is the hybrid banknotes. So let's just do a quick introduction here. Everybody knows cash. This all looks familiar to everybody. But if you look at it in terms of a monetary technology, it's a very robust technology. It's been around quite some time and still around and it's there for a reason. One thing about cash is it can be used by everyone everywhere all the time. You don't need a phone. You don't need electricity. You don't need anything. You can do a face to face transaction with cash. And over the centuries that we've had cash it's become very familiar and even very comforting to us. We know how to handle cash. We know how to budget with it. We know how to keep it safe, et cetera, et cetera. You don't have to know anything about your phone or private keys or public keys. You just have this piece of paper or polymer and you can do what you want with it. The downside is cash can be expensive. It's expensive to keep safe, to handle, to truck around. So there are downsides to it. Plus it also impedes a lot of what the digital world can bring to us. For example, cash makes remittances kind of slow and kind of expensive. You can't do any smart money with it. You can't build in smart contracts to your money as you could with a blockchain of some sort. So for example, a central bank can't go negative with its interest rates because cash is always there sitting at 0%. But with smart money, you could go negative or you could even do a positive remuneration on your digital money. Let's say you want to implement an economic stimulus of some sort. You could make smart contracts in your digital money. Say if you buy pre-cox, those dollars will go further than dollars spent elsewhere. And also with digital, you could do immediate government payments as everybody wanted during the COVID crisis. So there's upsides and downsides to both these technologies. And one way to bring it all together is to create a hybrid. It combines the advantages of cash and of digital monies. And basically a hybrid bank note is a traditional bank note that has the ability to access an electronic network and transfer value. The value on the note can be transferred via an electronic network when it's on to do it. But if you have a hybrid bank note and you just want to use it in the traditional way, you never have to connect to a network if you don't want to. And other attributes to a hybrid bank note is it's not a card. It's not a debit card. It's not a MONDEX or a whisper cash card.  And there's a specific reason for that. So it's denominated. It's not a debit card. It doesn't have multiple values. It has its value that's printed on its surface. And that's the value that can be transferred. And you cannot transfer a fraction of it. It's the whole amount or nothing. And over time, there's been two basic models of hybrid bank notes that have come about. And I'll talk about these. One is a smart bank note. A smart bank note basically has a chip. And the chip allows it to talk to a network. A crypto bank note does not have QR codes. And you can see that on the slide here, that both these bill have QR codes on how it talks to an electronic network. So that's the basics. OK, if we start going to the history, the idea of hybrid really rose in the 90s, believe it or not. And the first mention I found was in 1996, someone applied for a patent to put a chip in a bank note and to use it for security purposes. It was an anti-counterfeiting measure. And this idea caught on by 2001, the European Central Bank, the Bank of Japan, and others were thinking of putting chips in their high-denomination notes, again, for security purposes. And they were going to use a MewChip, which I think came out of Hitachi. By 2008, Hitachi had created Arthid Powder, which is, I think, 16 macrons across. And again, the central banks were looking at putting these chips into their notes, again, primarily for security purposes. When we get to 2010, here we have a picture of Ignacio Maas, who was working at the Gates Foundation, and he thought that maybe we can use these chips, a smart bank note that can transfer value. And his concern was financial inclusion. He wanted to make a smart bank note that would make cash handling cheaper. For example, you could ship bank notes that had no value and then charge them on site or basically turn the notes off so that they weren't so expensive to keep safe. As I said, this is in 2010. He writes his first paper working from the Gates Foundation, looking, use a smart bank note with a chip in it to expand financial inclusion. And I'll give you the basic layout, which I'll expand upon a bit later, that you would have a bank note and it would have a chip in it and it would also have electronic ink on it. So his idea was that you could have a bank note that's denominated and it could either be activated or deactivated. If it was activated, it had its face value stored in it. You could transfer that value. If it was deactivated, it was just a piece of paper and had no value in it. And you would be able to tell whether it was activated or deactivated by the electronic ink. The note might get grayed out if it had no value or some other method would make it readily apparent to everyone that your note had no value in it. So Ignacio Mas, to develop this idea, pulled in consult Hyperion, which many of you may know is David Birch's company. And Paul Macon and Andrew Whit come from his company, researched this and started to develop the idea of a smart bank note. In fact, they came up with the label smart bank note. And here we have a slide from one of Paul's PowerPoints from way back when 2010, 2011. And they gravitated towards using a card. They figured if you're going to use a chip, you might as well just put it in a card and make it more of a debit type card where you could have multiple values and these values would be shown on the card in electronic ink. Unless you would have an active icon or symbol of some sort. The problem with this was Paul and Andrew recognized this is, one, if you're using these really big chips here, you can hack them. You can start messing with them, change the values in them, things like that. So using a card instead of a traditional bank note would cause a massive pushback from the cash industry and also from everyday users who wanted or were used to having this piece of paper. And over time, this idea of having a note with a chip in it got picked up here and there by different countries, Saudi Arabia and others, but it never came off. Mostly it's a problem of the technology wasn't ready yet. Back in 2010, Paul and Andrew said, the technology to roll out the smart bank note probably won't exist until 2020 or 2025. And sure enough, last year a new company called Noteworthy was started to create a smart bank note based on Bitcoin using the Bitcoin blockchain and they are currently developing a smart bank note that will be backed by Bitcoin. Paul sends is the driving force behind that. So those are smart bank notes. The other thing we have are crypto bank notes. And these arose basically around the same time that Ignacio Maas was thinking about smart bank notes with chips in them. Around 2010, 2011, people picked up the idea of a paper wall for Bitcoin and figured well, we can put a denomination on this and start passing them hand to hand. And when somebody wanted to transfer value, they would use their phone and scan QR codes and transfer the value that was in a specific wallet that was connected to this card or this note and be able to move that value around. On the right side, you see bit bills. These are from 2011. I don't know if these were ever actually issued or not. But as you can see, the denominations are from 1 to 20 Bitcoin. So you know what the value of Bitcoin was back then. And these are cards and you would access the wallet that was behind these cards by there would be two QR codes on it. One was a public and one was the private keys. The private key was behind a foil protection on the picture. You can see the circle of the globe on the five Bitcoin bill. You would scratch it off and there'd be the private key and the QR code under there. So you would scan both codes and then you would be able to access the wallet. On the left side is the generation of these kind of Bitcoin paper wallet things. And these were bit notes and these never took off these more complicated. They had special software and you would generate another private key with it. But you would print these at home, the bit note company plan to send sheets of notes to your home and you could print them out on your printer. And again, these never took off. As we move forward in time. On the left is Andre Lipkin. On the right, you see some notes from Bitcoin Suisse. In 2013, Bitcoin Suisse put out its first Bitcoin crypto bank notes. And again, if you look at the image on the right, you'll see a QR code with the public key. In the middle, it says private key, you would remove that piece of paper. And under that would be a numeric code that you would be able to access the key. In 2019, Bitcoin Suisse put out a new series of these notes and they look a lot like regular bank notes. They're denominated Bitcoin, Ethereum and other cryptocurrencies. But they have security features just like traditional bank notes do with optical variant ink, ultraviolet and security. And the whole bet Andre in 2017 put forward the of a crypto bank note. And he used the one who came up with that term. Andre is a former head of the state printing house in Belarus. He was there for 25 years. And he came up with notes that were basically press ready given current technology and also the blockchain ideas behind it and how to interact between a note and the blockchain. And he's very big on using traditional bank notes and traditional bank note security features. Because if you're going to have these notes moving hand to hand, they have to have all the security that bank notes have right now. Because you cannot depend on some kind of electronic interface to make sure that the note you have is real and then it has about a minute. So what are the case reasons that we should have these hybrid bank notes? Well, some of it we've already looked at, you know, these things have been under development for 10 or 11 years now and people are still going at it. So there must be something going on that people think we need these things. And as we saw in 2010, it also smart bank notes started with the idea of financial inclusion of being able to extend digital money to people with spotty internet or no internet or spotty electricity. And one of the things that is still holds today is it's great to have all these cryptocurrencies and all these platforms that run on your phone. But what if you're one of those people who doesn't have internet access? What if you're one of these people who doesn't have reliable electricity? There are many places in the world and including in the United States where internet access is a real problem. And so it's great to have all these cryptocurrencies. But if you have no internet, they're really useless. So you need another platform, cash, which will operate anywhere at any time. And the same thing in a disaster setting. Again, internet and electricity is a problem. You'll need some kind of payment technology that will operate outside those parameters. And there are some CVDCs that are being designed to work under these conditions. As I mentioned before, the cash industry, the cash industry is pretty massive. There are various printing houses, there are companies that handle cash, move cash around, cycle cash. If you decide tomorrow you just want to go to a CVDC and, you know, we're going to just dump cash. This is a massive pushback that will occur from this industry in many places. Popular payment practices. There are people who don't like cash. They don't want to deal with their phone. They don't want to figure out how this thing works. They don't like the idea of a digital currency. They want their cash. And this is a strong point in many places of Europe. The Germans love the cash as do the Swiss, and they want to hold on to it. And as we've seen in the past year or so, there's been an increase in cash usage. A lot of this may be just for store of value purposes and not for use in retail payments. But again, people like to have this physical instrument that they can shove in a drawer or just hold on to and say, I have this value. It's not in the ether. It's not an electronic thing. I have this physical object. Digital money adoption. With a hybrid bank note, you get people who are cash centered to get used to the idea of using digital. And after a while, once they start using these hybrid bank notes and say, oh, I can connect to a network and move this money around. The idea of having digital currency or cryptocurrency doesn't seem all that scary anymore. And it can be a way to make that transition. Central bank policy implementation, like I talked about before. If a central bank wants to break through the zero lower bound, it has to have some way of making cash go negative. And with a hybrid bank note, you can do that. There are various ways that you can engineer a bank note when it connects to a network to go negative or there's various ways to make this smart money work. Enhanced bank note security. Again, back from 1996, the idea was put a chip in a note and you can make it more secure. And this still applies to today. Plus, there are ideas out there that you could make a note that is stolen, basically become worthless. So there are ways basically to turn off the money. So it's another layer of security anonymity. And again, this is a big point. If you are using a hybrid bank note just as a traditional bank note, you're passing it hand from hand and there is no record of the transactions. The problem happens when you connect that note to a network to move value around, then it is no longer purely anonymous. And here you have to deal with what's going on on the back end of the ledger. And of course, there are people studying how to make online transactions basically anonymous or mostly anonymous. Things like using a Zcash model, blind signatures, things like that. Carbon reduction. This applies really to Bitcoin or other cryptos that are using proof of work. Let's say you create a Bitcoin hybrid bank note. You're going to lock away all that Bitcoin to the value of those notes. And so basically Bitcoin can be used offline in a traditional bank note sense. And you're doing all these Bitcoin transactions, but they never have to interact with the blockchain until you do that connection. Until you take your smart bank note and put it up against your phone, then it interacts with the blockchain and you have to do the whole proof of work. So a Bitcoin bank note would lock up a lot of Bitcoin and hopefully stabilize the value a bit more, maybe even raise the value. And at the same time, you're not making all this electricity usage to go on. OK, I'm going to try and speed up a little. So how would these things actually work, say today or tomorrow? Well, let's do an example of a smart bank note. And here I'm using, of course, the US 10. So this note, we'll call this the hybrid 10. The hybrid 10 is going to need some way to show a user that it has a value or it doesn't. Remember, these notes have chips in them and can be active or deactivated. Value or no value. For this 10, if it has value, the symbol of liberty icon here, which is the torch from the Statue of Liberty. If it has value, this will be bright red and raised above the surface of the note. When the value is transferred out of the note, this icon will disappear and you won't be able to feel it or see it. And this allows anybody to see if this note has value or not. Or if you're visually impaired, you'll still be able to tell. So let's say you have this 10 and you want to send the value of this $10 across a network to your relative overseas. So you take your note, you put it against your phone or other apparatus that will read it. It'll transfer the $10 out, zero out this note, make the icon go away, and you transfer the money. Now, what do you do with this note that has no value? Mail, you could turn it into the bank or maybe some kind of retailer and maybe get a deposit on it of some sort. And they would recharge it and recirculate it. Or you could just hold on to it and transfer the money, transfer $10 back onto it by yourself and you have a new $10 bill. If you're going to crypto bank notes, there's two forms that Andre has come up with. One is a crypto note and one is a crypto bill. And I'll point out the differences pretty quickly. Basically a crypto note has both the public and private key on it. If you look at his original design on the left, the QR code is there with the public key and on the lower right hand corner of the hundred note is where the foil cover would be. You would have to remove that foil cover and the private key would be under there. And like I said before, you would take your phone, read both of the QR codes and be able to access the wallet behind this note and transfer that value. The problem with a crypto note is once you remove that foil, this note is basically burned and you can reuse it. And that could be a problem in some instances. With a crypto bill, you only have a public key on the note. So again, in his original design on the 10, if you want to transfer value, you would have to take the note to the issuer. Let's say you want to transfer this 10. You'll take it to a bank, a kiosk, or some other retailer. And they would read the public key and then behind the scenes, the private key could be accessed. And the value would be moved by the issuer from one place to another. And this would work basically as silver certificates and gold certificates worked in the US in the past. And you could reissue this note until it wore out. And this is very basic banknote technology and this could be run on a press tomorrow. And all right, check my time. And so I laid out kind of the idea and the case for hybrid banknotes. You can use miscache, but you can go digital when you want. It should it all cover a lot of bases, solve a lot of problems that are kind of creeping up with this transition to a more digital platform. So I see it basically as a transitional device. And eventually sometime in the future 30, 40 years from now, we won't need banknotes of any kind anymore and will have switched over to a purely digital platform. So that is quickly my presentation. And be glad to take any questions you got. I'm looking at the chat now to see what's going on. Nothing much going on in chat except terminology issues. Yeah. So any questions, please come forward, put up your hand. And yeah, actually, there is a way to put up your hand. Yeah, it's the big. Yeah. All right. So basically, anybody can ask questions. Mark, of course, has got his hand up, which is a cue for me to stop talking and Mark to stop talking. Thank you very much. That was really a fascinating discussion. I was actually just thinking about, well, two things. I mean, why sort of one, would it be established as an each one as an NFT to make each one sort of a, you know, serially like a like how banknotes currently now have a serial number. So giving them a unique certificate, even though they're sort of fungible in the value. That was one consideration. And the second one I was curious about was thinking around just having you know, instead of having this sort of scratch off approach, what were the other options that you could actually keep them more in circulation? I was thinking just so you could validate them currently how now they scan a 50 euro bill or $50 bill, whatever. When they want to check it, that it could be sort of with the assumption that it's valid for those that don't have the digital access, but that it could be verified at any time. And maybe there's certain like checkpoints throughout a system that would that would allow it to pass through. So you wouldn't have this sort of disposable approach or sort of a one off or rechargeable, if you will think about that. Thank you very much over. Yeah. First off, I'm not sure because you're I'm more focused on the physical side on the banknotes side. And it's I need to look more into the NFT idea. It looks like both those ideas have been already presented. One, the NFT ideas already been presented as the one with the scratch off, right? I mean, it's basically once you do your transfer in a way, it's gone. The other idea where reuse is needed, you already presented it as a raised red liberty torch idea where you can recharge it. So both of those are already in circulation as ideas according to what I heard. But maybe I'm wrong. No, the two reusables are the smart bank that has a chip or the crypto bill, which just has a public key on it. One of the things I was thinking about is is serial numbers at least primarily in the US. And I think with the euro really don't serve any purpose except on production side. It's serial numbers are used basically to track production and to see what's been shipped out. It's not used as a security item of any sort. And the Fed certainly does not track individual notes. They really don't care about the serial number unless they see it twice. None of their equipment will read the serial number. To a certain extent, serial numbers are a legacy. And some banknotes don't see a reason at all for putting serial numbers on notes anymore other than that people expect them to be there. And they'll say this isn't a real banknote because it doesn't have a number on it, even though that number is almost meaningless to most of the central banks. You know, once in a while you can record them if you're paying or ransom or something like that. But you really don't see it anymore. Well, the serial number has been used in some heist movies as sort of a proof. Like, you know, if you're getting that's why people ask for small bills or whatever when they rob a bank or when they lift things. And when they counterfeit bills, they always go for the smaller denominations. Nobody counterfeits $100 bills. They probably counterfeit 20s, which are the most commonly used bill. So the serial number has sort of served as a plot point for many for many movies.  I mean, there is that. In fact, we are going through a whole exercise on token taxonomy framework where we are defining the characteristics of a token, especially a note. In fact, you can see that even in other fungible instruments like stock certificates, bonds, you know, there is, I mean, let me let me put it this way. The use of bearer bonds is frowned upon by the Fed for the very reason that banknotes are also under attack as being especially higher denomination ones as being a vehicle for crime. Which, of course, is also the tar, the brush that they are touring Bitcoin with for other reasons. Anyway, so it's very interesting this stuff. But let me, I mean, unless somebody else, oh, Adam, Adam Elevator has a question. Hi, one of the primary efficiencies of cash is face value, the ability to instantaneously transact with efficiency. If we're turning these notes into wallets, why not just use a wallet? Specifically, this is the scratch off consumability function that we were talking about introducing variability into the face value of the notes. This eliminates the ability for an instantaneous transaction and would therefore require each note to be checked, whether it's looking at the electronic ink or scanning it and checking online. I'm not sure exactly what you're asking. I'm asking that the very, the consumability or variability of cash would not be a combination of advantages in the future of payments, but rather damage and otherwise advanced piece of financial technology of a cash note. Should we not be separating cash into a face value of certain denominations and having digital wallets separate as digital wallets or physical wallets to supplement crypto hybrid banknotes?  They just introduce confusion. Why not just use one thing for what? Like, you know, cash for cash and crypto wallets for the other reason? Is that what you're saying? Yes, but not reducing the crypto banknotes idea. You know, we can have hybrid crypto banknotes, but of strict denominations and specifically debating the variability of the value of those notes. You described it as a scratch off or consumability. Well, there's two types, right, which Franklin was talking about. One is the scratch off, in which case the note is worthless once you've done it and you have to take it back to the to the issuer. The other is where, you know, the note has got some kind of a raised imprint, but presumably it can only be loaded back with the same face value. Otherwise, the face value and what is inside the note will be different. So I think what you're, I mean, according to what I understand, anyway, Franklin, you can answer the question. Yeah, Ignacio Maas had originally an idea that you could have a variable value on the note. You could charge it with whatever you wanted. And he kind of moved away from that idea after a while because it creates a real problem with how people traditionally use cash as a way to budget. Like I have so many fives, so many tens. There's another problem with any central bank is going to be very worried about the distribution of denominations in an economy. And if you start sending out notes that are basically can be assigned any value. You could send out, say, a skid of notes out to some community or whatever, and they all become hundreds. Somebody gets a hold of them makes them all hundreds. And there are no ones, twos, fives or tens for that economy to function. So one reason why there is a printed denomination and a fixed denomination is that a central bank can have this distribution of different denominations in the economy. So there's two sides to it, the consumer side and the planning side, you need to have these fixed values. And that's why, personally, I moved away from the ideas that consult a period came up with with a variable value or basically it became became a fancy debit card. So those were the reasons I moved to a fixed denomination and I think that works best. But wasn't the problem solved with the ink that changes the face value, like, for example, like 10 maybe printed, maybe printed in this ink. And then when you change it to five, it would show five rather than 10. Again, you run into the problem of the distribution of the denominations. A central bank would not want somebody to have that ability. I get that. But say if you're somebody's issuing a Bitcoin bank note, they may say, you know, that's perfectly fine. Make it whatever value you want, because except you can't spend it. Unless you take it to an exchange anyway. But a private firm would not be as concerned about the distribution of denominations throughout an economy of their specific bank note. But certainly, you know, you could a stable coin could be attached to these or, you know, Bitcoin, Ethereum, whatever you wanted. OK, yeah, I mostly see it as something that will link more or be most useful for a CBDC. But the central bank, they'll want some kind of physical manifestation of their CBDC. And this this idea makes more sense. But let me step back from this a little bit and say, we don't need these. Why? I'll give you several reasons. One, one bank notes are bank notes, let them function the way they are. I mean, so they will remain no matter what CBDC or other digital instrument you come up with. So that will satisfy the cash hungry hordes. OK, that's one. Second, there is, you know, with all this technology, there would be confusion between this between a the face value and what is actually in the note, whether the note is valid or not with the raised you know, so depending on people who are using it, they may say, oh, I don't, you know, I'm confused. I thought this had value when I accepted it, but it turns out to be a dud. So so that way, you know, and also some of the problems that Adam and others brought up. So why not have something else like for example, Tangem has been presented on this on this forum. They talked about the smart cards that can function in a disconnected way. Unfortunately, you cannot check or even see what is in there unless you have electricity of some, I mean, either to read the RFID or anything like that. So that seems to be one of the biggest problems. But is the problem with, let's say, a feature phone, which is, you know, used heavily in Africa for MPSA, for example, and the phones are much more ubiquitous than people seem to suggest, meaning even the, you know, very poor people seem to have feature phones, which need not necessarily have, you know, be connected to the internet or whatever, but it does provide a means of transferring peer to peer money, peer to peer. So so there are other alternatives. And I mean, certainly, yeah, there are alternatives. And I would not argue we should just do hybrid banknotes and, you know, forget everything else. Like this, I see hybrid banknotes as part of the mix as this transition occurs. You'll be, say, you'll be having hybrid banknotes. You're going to have your phone as the transition occurs. There will be places which will only accept cash. We have to know I and a lot of us have to remember there are places in the world that do not want to deal with digital payments. If you go, you know, to the middle of the United States, you're going to run into that. You know, they may not have all that great cell phone access. They're going to want to deal with cash and, you know, not these other things. Is there a demographic divide there? It's a demographic divide. It's a generational divide. I'm trying to think how I would convince my mother to, you know, okay, you know, give up your cash and start using your phone from here on out. She'll look at me like I'm insane. You know, what am I going to do with this? How do you handle it? How what's a QR code? You know, none of this makes any sense to me. Well, while my daughter would say, why do I want to carry any cash around? I have my phone, you know, cash is an old people's thing. You know, I don't deal with that. But since your mother and your daughter exist in the same world, they have the choice to have cash as well as a phone. So problem solved, I guess. And as far as you are concerned, you are somewhere in middle. You carry cash sometimes and you carry the phone other times. Anyway, as far as capital markets go, I was wondering, you know, there's only two more minutes. What, you know, if any, we didn't go into those interesting questions about the money supply, about whether this will make any kind of a trading easier. Or I mean, I'm talking about digital assets, not. Again, I can, you can see one thing about hybrid bank notes, as you pointed out is it's going to take a lot of public education if you roll these things out for people to know, okay, you have to look, say on this 10, you have to look for this icon and make sure you can see it. And it's raised above the surface of the note to say it's, it's a good note. And you have to, you know, educate people and, okay, what can I do with this new note? And, you know, say the Fed would create apps and, you know, here's your new 10. Take it to your phone and see what you can do with your new 10. It's going to be a massive public education thing that would have to be rolled out. And anyway, it's also part of a way to transition people who are used to cash to start thinking about, hey, there's this, we'll call it a CBDC. There's this digital dollar now, and I can do all this stuff with it. And I can move it back and forth with my regular dollar. Again, this hyperbank notes are a transitional device. They're not, they're not going to solve payment problems for the foreseeing future. It's, it'll help the movement from one platform or from one, from a 19th century technology to a 21st century technology. And I guess I'll conclude there, if for us. Yeah, yes, beautiful. Thank you so much, you know, for showing up and talking about this very sort of, it's an edge idea, especially in terms of CBDC. I'm not saying it's an edge idea in terms of, there are no edge ideas in Bitcoin, other places. So that's, that's that. The other, you know, another thing that you talked about where it's going to be a hybrid, I mean, a transition technology, we might be, we might end up with cash and hybrid bank notes for the foreseeable future.  I'm going to close the end the recording, right. And I thank you again. Hopefully you've been at least amused by this whole episode.


These are my five favorite easy plants that love bright sunlight. The bunny ears cactus. As you can see it looks like a bunny so it's an adorable cactus and it'll be very happy with bright light. The blue toxic plant and this one is very cool because as you can see it comes with a white powder on the leaves which protect her from the sunlight. The croton we have lots of bright color with this one. I couldn't miss the spider plant because it's one of the easiest plants that I have and it's so pretty. And the android plant that just looks like a piece of art.


Christian Tagliveni's photography is a remarkable body of work which is going to introduce you to fantastical worlds that are equally familiar and yet oddly surreal, like half-glimpse fragments of Christian's fertile imagination. Today I invite you to discover this amazing collection of portraits that draw the inspiration not only just from the modern day but also the world of Jules Verne with a dash of cubism and Italian Renaissance painting added for good measure. Along the way we're going to meet the cardboard ladies, blast off to the stars with 19th century French steampunk aeronauts, and spend time with some futuristic royalty. How's it, how's it? Thank you ever so much for joining me here today as we look at this fantastic book simply called Christian Tagliveni. Christian started his art photography career photographing very much in the style of Erwin Olaf so Erwin Olaf creates these contrived sets where people are in them and they're telling a story with without words like a single image and they're very elaborate and they're very involved. I'm a big fan of this type of photography and I think Christian has done it very well here but he decided for whatever reason that this wasn't quite working for him and it's this next series that he came up with and I'm going to guess that Dama di Cattone is excuse my awful Italian is ladies of cardboard. I think that's probably not a bad one. Let me know in the comments anyway. I am going to use the new TPE brush of truth here to point out because rather than throwing my hands all over and these photographs for me initially are very reminiscent of like the da da sort of period the Bauhaus you know stuff like that where it is quite cubist and it does indeed say here cubism and what this is is actually a fantastic outfit that is comprised of sheets of cardboard. Christian made this outfit and one of the things that is absolutely gorgeous about these outfit is the way they sort of distort our reality and how we interpret the photograph. The reason they do this is that if you see the waistlines here and here and here quite clearly this lady is not that thin and neither is her and what's happening is it's a little visual trick of the eye. It's a very subtle arrangement that throws our eye off and reaches out to us but not being obvious. We can see this in play here you know there's the nipped waist again and what's happening is the lady is leaning through the cardboard. The cardboard is on a separate plane to her which is a way of being able to create this oddly surreal look to their silhouettes and their figures which is something that comes through Christian's work throughout his career. The next series that Christian worked on is called 1503. Now this obviously we can see it's a bit of a departure. These images are more reminiscent of sort of the Italian Renaissance. They've got more of a painterly quality to them a painterly feel and again we've got these outfits that are made by hand and everything a lot of great attention is going into the whole composition of the photograph. One of the great things about a book like this is that you can see the evolution of a photographer's style when they when you're going through this and Christian comes back to similar feelings similar themes again and again and as we go through the book you're going to see a fantastic growth in his photography and how the images become so much richer and so much more rewarding but with very very little subtle changes and it's good notion to us all and that how trying to improve your photography is not necessarily great leaps but just little polishes. There's that theme again of the the oddly surreal body shapes and we've got this elongated neck here in this lady and I just I loved that it's like a little signifier of Christian's work and it's not brash it's not in your face. This is a great example of this evolution that I was mentioning with his photography. The card ladies at the beginning of the book have now evolved into something that feels a little bit more polished a little bit more refined and this is this is a hallmark I think of confidence that that an artist is starting to find their voice and starting to be able to express themselves with greater intent. These two photographs are a wonderful illustration of the the color palette that Christian uses in his photography where they are really harmonious and lovely and I do like the work say for example of Alex Webb who's quite brash and is quite bold but at the same time I also like this it's different strokes for different you know different strokes for different folks and and sometimes you want loud sometimes you want rock and roll and sometimes you just want classical chamber music. These photographs remind me somewhat of Desiree Dolbyn who is a Dutch photographer who also creates wonderfully sort of haunting images of Renaissance kind of feel periods and if you are interested in looking at her photography which has a lot of similarities to this particular section of Christian's work I will put a link up for you at the end of the video. I'm a huge fan of the turn of the century or should I say the turn of the 19th century photography going into the 20th century that is that that Finde-Sackel period in in France and Steampunk and Jules Verne and and it's no surprise that when I was initially introduced to Christian's photography it was through this voyages extraordinaire and my French also terrible sort of period and and this this is for me probably the most exciting part of his his photography. These photographs have a that Steampunk aesthetic to them they have this luminaire brothers aesthetic this this idea that it's a futuristic world but it's in the past which I've always loved that look. These photographs also put me in mind of someone like Felix Nadar who was a great French portrait photographer and it feels like he could have been here photographing these aeronauts as they were you know preparing to take flight to space. It's great that we're being invited into these worlds that Christian is creating for us that he's is this figment of his imagination that he says come come with me on this voyage as I show to you what it is that's going on with with my mind I love the fact that all these photographs that Christian is creating of like figments of his imagination that he is taking the time to construct and present to us and all of these photographs that you've seen they are all made by hand everything in them is made specifically for these photographs the outfits that the ladies are wearing the sets everything leaps forth from his imagination in the next series that Christian puts together you can see he's gone back to that original idea that he had with with Owen Olaf you know these these the bigger sets and more of a more of a set piece sort of feel to them as sort of a chapter from a book or a still from a film but now in the space of what the 10 or so years from the from the very first photographs there's so much more confidence so much more delicate way that he's treating the whole set there's there's more depth to it there's more emotion it's not simply a a pretty picture it's now starting to have a soul it's now starting to have a voice of its own hopefully throughout this whole book you can see what happens when a photographer gets more confident gets more ability to explore the worlds that he sees inside his his mind and and and bringing them to fruition to showing them to us and here's a here's a great example all of the photographs from this particular period they all have this wonderful rich sort of feel to them they have a a lovely color palette going on each is individual and yet they sort of stay together you know they just look so marvellous and i just love it i love the fact that he is now starting to give expression to his his own imagination in a full and vibrant way looking at these photographs there may be something that you will have noticed and if you look carefully at this there's a little clue in there the shape of this young lady's hat helmet whatever you want to call it is rocket shaped and and her outfit is quite clearly in the Renaissance sort of period so that's the kind of the rocket shape that you see there and i'm feeling in this that she or he sort of christian rather is starting to put the world of the jules verne steampunk and the world of the renaissance northern italy artist together he's melding them into something that is uniquely his own vision once again you can see this idea at play so everything in the bottom part of her has fabric has texture has old world but this this magnificent looking headpiece either looks like it's it's burnished wood which it most likely is or it could be plastic but it just looks like there's a mesh of futuristic and retro i don't say retro it's sort of historical in there and it's absolutely lovely and i and something i haven't really touched on but i think it's worth bearing in mind is or mentioning rather is that all of these people all of the people he has photographed are not professional models they are people he has found on the street and he has asked them to photograph and if you do take a lesson from this idea of asking people on the street to be photographed it's that anybody can be a great model for you if you give them the tools to express themselves just as much as a photographer needs to express themselves through their own photography so does the person being photographed and i always find it's exceptionally important that you give the person being photographed something to think about give them a role to play just as much as they're wearing costumes and they're wearing outfits that make them look a certain way they need to feel the certain way and if you ask somebody to think about something think about maybe a loss she's feeling introspective here she's thinking about something maybe christianne has asked to say to think about something that think about the first time that a pet passed away or the first time your heart was broken and channel explore that feeling and that gives your your photographs so much more depth somewhat unusually for a lot of photographers christianne goes into depth at the end of the book about how the the sets and the you know the the constructions of the photographs were were made and i love the fact that you get little insight into it not from the technical point of view you know the cameras and what have you but from the the way this world is constructed and you can see the effort and the the the attention to detail and the dedication that goes into creating these photographs if you do enjoy looking at the likes of christianne then i would hardly suggest that you check out the work of Desiree Dolrin i'll put a link up to her on screen for you now thank you ever so much for being here today and i look forward to seeing you again soon


The presidential candidate of the all-progressives Congress, APC, Bola Ahmed Tinubu, has been urged to turn back on issue-based campaign rather than character, assassination of perceived political opponents, the chief press secretary to the governor of Delta State, Olyssia Ifejika, gave the advice while reacting to a statement credited to Tinubu, where he took a swipe at Senator Ifejikoa, the vice presidential candidate of the PDP. The PDP presidential candidate, a correspondent in Asaba Friday at Pumejera reports that Ifejika said that the choice of who was the best vice presidential candidate in the major political parties and the parties to vote for in the 2023 general elections was left for Nigerians and not for one single individual to malign political opponents. High at the line can be wondered to the extent of three times. Tinubu's swipe cannot diminish it. Tinubu's snot, whatever, cannot diminish for the goers, I think. So we're leaving to ask Tinubu to confine himself in the context he has, it's very important given the baggage, the baggage of this thing he has. We ask so much about him, the drug issues that maybe the life of the people that may not seem reasonable for him, he should continue to do things. But in mind of all, he said that he would go back and he could just have saved his life from all the problems he had to face. It's an example of the final call. It's in that bracket of those places he could say that he is who he should vote for, for those that would be other places that are who he should vote for.


The gap between basic science and clinical research is growing wider, leading to a crisis in the translation of scientific discoveries into treatments and diagnostics. This includes a lack of reproducibility and translatability of preclinical findings to human applications, as well as high attrition rates of drug development. To address these issues, we must consider several factors such as poor hypothesis, irreproducible data, ambiguous preclinical models, statistical errors, organizational structures, lack of incentives in the academic setting, governmental funding mechanisms, the clinical relevance of basic research, insufficient transparency, and lack of data sharing in research. We can also look at new strategies such as open innovation models, entrepreneurship, transparency, and decision-making to better adapt to the changing landscape of innovation.

So today I'm going to tell you how Hyperledger Fabric can move charity to a principle new level of trust. So let me say a few words regarding background of our system. So what is the platform about? So the Karma project is a charity foundation platform based on Hyperledger Fabric. It is developed for fundraising and it brings charity to a new level because of new level of trust. So this is a platform with really big charity funds. This is about building an ecosystem of really trusted funds and like it's a sort of consortia. So key challenges that we are facing with the classic one fundraising systems. So first of all it's lack of transparency. You don't able to get all the information you want and you feel like it will be absolutely clear but you are not getting this information and you start to feel uncomfortable with this that you are not controlling the way of this information and the way of money how they are spending the fraud by some really bad organizations and of course inability to track the way of all this transaction I mean from the very beginning when somebody need help and you are giving money to this person or project or charity foundation and then how they are spending it and the results. In a typical classical system right now you for example able only to give someone help and then see like nice pictures that you are for example somebody got some medicine or some operation and so on. So what benefits this system gives because of blockchain. So first of all it will be able to bring principle new users who not believe in a classic charity funds right now in a classic system and the second important point that we think that this kind of system are able to invite younger generation. It was a problem and it is still a problem right now that people from 20 to 30 years old they don't have how to say a culture of regular charity as an older generations and it's a really big problem right now for charity organizations and they are working on it and the most important thing to know about it that it's not a principle new way and we want to avoid for example classic one systems no. It's a complementary way to improve the way people are getting fundraising and so on. So few words about interaction models and what participants do we have on the platform. So we have philanthropist who donates funds for people who need help for people for projects for charitable foundations. We have these charitable foundations who are organizing fundraising for projects and people who need help. We have bank or bank service providers who guarantee spending of money and who providing us information regarding this spending and we have beneficiaries people who need this help. Potentially for the next releases of the platform we are planning to connect service companies and medical institutions who will be able to provide information regarding the final stage of spending on this platform. So how donation projects look like on the platform. First of all the beneficiary places an application for assistance on the platform that the person need help. Then there's some check from on the side of fund. They review this application and in case that everything is okay they are taking this on board. Then rises fundraising project on the platform and after collection is completed the fund withdraws money and then ordering targeted services or products or what else is required. And after that as I mentioned before service companies and medical institutions provide data on these fund spends and it really improves the process. And after that system of course automatically generate reports and so let's move to demo how it looks right now. It will be easier to show it on video and I'll provide some of my comments. So this is the marketplace of the projects. I'll be putting it on stop maybe a little bit. So at the top of this we can see the most urgent projects for which we need help urgently. We have some different directions of projects. So we have help for children, for adults, for older person, for animals and some information regarding farms. So returning back to a project so we are going on the first one to help this dog for example its test. We have information regarding this project. We have information regarding people who already helped and so on. So this is a help page. I am taking amount. Now it's available in rubbles or in dollars. We are providing amount of money that we want to put we providing our email and we are specifying is it a one time help or we want to do it on a basis. So right now we have payment service provided cloud payments. So this is a test transaction. So we already have integration with them but this is a test card and after that we are generating a call for the API and we can generate positive or negative transaction as we want. In future of course for sure it will be a real one transaction. So we are providing a number of card, all the necessary data and then email and after that paying. And as I mentioned before here we are specifying do we want to make it successful or unsuccessful transaction. I am taking successful transaction and after that I would like to show you how it looks in blockchain explorer that it's real. Right now we have still the same amount. So we will go to explorer but first of all I would like to show your email that I got from the fund. Yeah this is a new one so this is the completion of this transaction successfully from the perspective of bank service provider. So returning back to have explorer so we can see this last blocks last transactions and last events and we already can see our transaction for this money transfer here. So let's go in transactions. Yeah this is karma co-animated transaction and let's go inside. Yeah so here we can see the amount of money and all this information. Yeah and after that we will return to a user page on the marketplace page and then we can see that amount have changed. So this is the main functionality that I want you to show. Of course it's bigger. There is some information regarding funds that are different types of fundraising. I mean you are able to support not only concrete project but you are able to support fund if you want some charity organizations because it's every time it's an issue to support this fund. So what are the main things I would like to mention finally. So first of all charity platform based on a blockchain can significantly increase the amount of money we are able to collect for charity organizations. First of all karma second sorry karma project demonstrates the novel approach when we implement permissions blockchain for a public charity platform. The third thing that was really important because we make a really great research and we got a feedback from quite a lot of charity foundations. So this platform meets high standards of accessibility. So it's not only about people who need help but for people who is helping as well. Because we all different and we have all how to say all of us have really different level of capabilities for using platform and it was really really important for us to support all people to use this platform. And the last but not least it's really crucial for us to provide correct message about blockchain to a wider community. I mean you are not able just to say it's blockchain just believers we are paying a lot of attention for this and we are planning to leave some kind of educational section on the platform. To provide like you know nice videos explaining why blockchain is important and why. Blockchain can help with this process. And the last thing that I would like to mention. So we are inviting all people who is interested in this to contribute with us because we have our project on hyper ledger labs and all of you more than welcome. Please join us we will be happy to see you in our team and to make it more international. Yeah so thank you and I will be happy to answer your questions. No questions then thank you once again for your attention. See you. Oh sorry sorry. Yeah for sure. So the idea here is to build and trusted ecosystem and to connect some how to say great validators on the network. So first of all it will be operator of the platform and which can grant you know the the normal work of this platform with all these transactions and the flutter and so on. And secondly we are going to invite as I mentioned charity really trusted charity organizations to be validators as well. I mean two or three at the beginning but after that maybe we will have more of them on the platform and they will guarantee this correct working transactions.


Hey everybody, Brett here with Summit Auto. I just want to say huge shout out to Mark and the used car department at Summit Automotive for getting me my dream car right behind me 2013 GT500 and of course Summit Automotive for helping make this happen and a special shout out to Woodside credit if you haven't checked them out for your classic car and Collector car needs for financing Woodside credit throughout of California. They're legit talked to my guy Chase that helped me out and they will get you a an amazing term and an amazing rate and Be able to fulfill your dreams like the car behind me right here. So let's go check it out. This is a 2013 Ford Shelby Mustang GT 500 it has the 5.8 Supercharged V8 engine 662 horsepower They only made this engine in two years 2013 was the first year and 2014 was the last year This is also was the last year of the GT 500 until they came out with the new body style one Recently, but this was the last year of this body style GT 500 this color is deep impact blue and What really sold me on this particular car is you'll notice that it does not have stripes and I kind of like that Stripes are a big chore if you own a car like this whether you're waxing it or just maintaining it Those stripes can get messed up. They're hard to Replace they're expensive to replace you have to find somebody who can actually replace them and It's just I kind of prefer that it doesn't have them. However, this one does have side stripes on it I think somebody put these on Aftermarket because the original window sticker says that this car came with no center stripes or side stripes So I'm pretty sure somebody put those on aftermarket. I like them on the side They're not as big of a hassle as the ones that go around the bumpers and down the center of the vehicle but 5.8 liter supercharged V8 engine This one has the SVT performance package So you get the 19 inch wheels in the front and the 20 inch wheels in the back Deep impact blue. What's cool about this car without the stripes is that it was one of 41 Deep impact blue GT 500s for 13 without stripes. So I really like that aspect of it gives it a very nice rare vibe to the car and Just wanted to check out in the trunk because I got the build sheet as well as the original window sticker Or the build numbers I should say the production numbers. Here's the original window sticker You can see that SVT performance package the tape stripe delete over this top stripe delete This one has the electronics package with the navigation, which I really wanted has the shaker pro system Which I really wanted and it has the Shelby car cover, which I really wanted as well. There's the car cover There's the shaker pro and you get the subwoofer the shaker 1000 So here's the total production build numbers you can find these online I'll try and link them in the description below To pictures of these but it tells you For your color whether it's a coupe whether it's a convertible how many were built with each Particular option. So I got all the ones of my car highlighted. So with the normal regular seats You can see this was one of 48 cars out of 530 in deep impact blue with the regular seats It was also one of 41 deep impact blues without stripes And then it was one of 369 with the navigation system and the performance package 450 had them and then the SVT I'm sorry That's the same number performance package And then down here the shaker 1000 with the subwoofer is 293 were made and then the full vehicle cover 307 in deep and impact blue had the Car cover so really like those sheets. So one of 38 Or one of 48 with the regular non-recaro seats in black and one of 41 without stripes Gives it just a little bit of its own Club, I guess you could say Car sounds amazing. It's a two owner. It's always been owned in Wisconsin and really really clean. I Couldn't find any dents on it. The previous owner loved to wax it There was just wax all over. It's still on the plastic. I got to get it off yet None of the wheels are scuffed The interior you get the regular Bucket seats. I think they're more comfortable than the macaros you get the embossed cover on the backrest you get the suede inserts Power driver seat, which you also do not get with the recaro seats has the factory floor mats Auto headlamps launch control the dampeners and the different steering feels power windows locks and mirrors and Really really a sweet ride Everything works. There's nothing wrong with the car the steering wheel is like new. I mean look at that And I plan on keeping it like this. I don't I don't really want to do anything to it You get cruise controls Audio controls, but I really don't want to do anything Special to this car as far as aftermarket parts or anything and it only has 7,564 miles and while I absolutely love driving this car I don't think I'm gonna put a ton of miles on it really just want to keep them low I feel these cars are really gonna go up in value in the next Five to ten years. We'll see if that happens. I think it's gonna happen, but who knows I'm not right about everything has the Sync radio Actually, it's not the sync radio, but this is my favorite radio in the Ford products because you can Store music onto it so I can put CDs in there burn them to the Hard drive and then just not have CDs in the car, which is really nice Yes, I still use CDs. I'm born 82 so Took me 40 years to get my dream car, but I got it and once again thanks to summit mark Lake City all those guys. They're huge help to our business and Especially these sports cars and thank you so much for helping me find my dream car and Special shout out to Bobby if he's watching the video.
