 Hey, happy Halloween everybody and Welcome to DevCon 2018 Prague edition Is everybody good? Y'all get some little little you get some breakfast get some little sandwiches with the crust cut off Like mom used to do We are really excited that you're here This is super insane. This stage is very large And We have a really fun morning plan for you, and I'm your host. My name is Jonathan Mann, and I'm a songwriter and I write a song a day and one of the things I do in that Capacity as the song a day guy as I'm sometimes called as I make Songs for conferences Like this one very often these songs that I do these conferences are In industries that I kind of don't really know anything about or frankly no offense to them, but like care about like you know speech language pathology and home health care and Carpet salesman and things of this nature But that's not the case today, and I'm really excited to tell you about that and why that is But first I'm gonna introduce myself a little bit. Like I said, my name is Jonathan Mann I'm a songwriter. My favorite food is pizza Yeah pizza. Let's hear it for pizza My favorite color is purple as is evidenced by this song that I wrote one time called All my shirts are purple My parents are both psychologists, which is maybe not surprising but um This is them exactly four years ago on Halloween four years ago. They were Freud My dad was Freud and my mom had a little sign on her that said slip Come on My parents they're done, but I love them This is my family I live with my family and my wife my two kids in Jersey City writes out of New York a little bit of history about me in The mid-2000s I was writing and performing a rock opera based on the Super Mario brothers around Los Angeles Indeed, thank you and a little while after that I was making early YouTube videos as Gameju and Gameju went around and sang songs about video games and interviewed people about video games and gameju's two biggest achievements Were Waiting 36 hours in line to be the first person to get a wee on the west coast Yeah, I did that Rather he did that And I tracked him down some might say stocked Which I think is a little strong But I tracked down Shigeru Miyamoto Creator of Mario and Donkey Kong and Zelda and every game that you love you guys know who Shigeru Miyamoto is I Wrote him a song. I tracked him down some might say stocked and I sang it to him in a hallway and He was very gracious. So that was my biggest achievement as as gameju by far Thank you. So in late 2008 almost exactly 10 years ago, you know, I just looked it up today Is actually the 10th anniversary today of the Bitcoin white paper October 31st. How how auspicious is that? So Right around that time. I was living This is around that time. I was living in Berkeley, California And I was unemployed. It was the height of the financial crash I was sort of done with gameju once you sing to Miyamoto. It's like where else are you gonna go, frankly? and so I was looking for a new project and I Decided that starting in January. I was gonna write a song a day 31 songs 31 days January post in the YouTube that was gonna be my next project So I did that I did 31 days and it was going pretty well. So I decided to try for a year and all of 2009 came and went and I decided to just keep going and Going and going and that is how I stand before you now having written 3591 songs in as many days Thank you Very much. I'm in the Guinness Book of World Records. This is true They made a new category for me called most consecutive days writing a song She didn't exist before I did it and as long as I keep going and no one's no one Yeah, as long as I keep going I think I'm gonna hold it for a while because someone would have had to start younger what? Yeah, longest chain exactly longest chain unbroken chain. It's exactly right One of the animating theories behind song a day is called 70 2010 This applies to any creative endeavor including the things that you all do in this room, which is 70% of everything you make is gonna be mediocre 20% is gonna be bad shitty throw it out and 10% is gonna be great So the more songs I write the more songs end up in that 10% category That's my theory anyway About a year ago I was at a conference in the backwoods of Canada northern Ontario. It was very cold. I was singing in front of a lake and One of the tracks of this conference was cryptocurrency. You all remember what was happening this time last year Things were going a little little crazy little nuts. My impression of the whole situation was You know gave me the heebie-jeebies the finance bros frankly and the you know lambos and the Speculation so I was like eh, whatever Out of the woods came walking this ethereum magician He was not called that at the time, but that's what he was and he took me under his wing and this is a true story he showed me crypto punks and Blew my mind I got really excited by this thing that someone had built on the blockchain That was fun and interesting and unique and weird and I loved it This ethereum magician gave me $40 in ether and said go play with this and I spent many long hours on telegram with him saying things like okay, like what so what's gas and What am I being asked to accept slash reject here and did it work? Did that go through? I'm really confused by all these things that are popping up on my screen and Yelling at me in Meta mask. Sorry Meta mask But that was my experience but I I bought my first crypto punk his name is Lucky Dan and I fell completely down the rabbit hole. I became obsessed with the idea of digital scarcity. I Became obsessed with the idea of like what gives things value I have my I've been working for the last year on my own NFT project based on crypto punks Where I'm tokenizing every single song from song a day and releasing them as a one-of-one collectible I started a podcast. Yes a podcast big surprise called digitally rare about digital scarcity and Two weeks ago I was at the NFT summit in San Francisco where I met Aya Miyaguchi who you hear from in just a minute and She invited me to come here and Make a song for you all and so that's That's what I've done Thank you don't clap yet. You haven't heard the song. All right, okay So this is the song. This is the official DevCon 2018 Prague edition theme song This is the chorus. We're gonna learn the chorus. We're all gonna sing it together I'll sing it first to teach you and then you guys are all gonna sing it with me And then and then I'm gonna bring Aya up on stage and she's gonna talk and Vitalik's gonna talk There's gonna be a bunch of talks and then I'll be back at the end of this morning session to recap everything that we just heard In the talks along with this chorus. So the chorus goes like this B Ydl Casper's coming east 2.0 new ways to govern those radical markets are calling to you don't I see oh When there's work to do you gotta be you I So that's it. That's the chorus Thank you Thank you. So now Let's just sing it a couple times. Let's just get it into our brains. Let's let's get that in there I didn't put the BU IDL part the where apart where I repeat that because it's just spelling it out Which I figured you guys can handle so Let's work on it. So here we go what the B is like a lead-in. So it goes B IDL that makes sense. All right, one two three B L Casper's coming east 2.0 new ways to govern Not yet. Not yet.

Thank you But you guys will get it just one more thing before I leave the stage This is the sponsored portion of the song So the name of a sponsor tier and you're gonna alternate.
