Mee georganiseerd en ondersteund door SETUP (http://setup.nl/) en Openbare Bibliotheek Utrecht (http://www.bibliotheekutrecht.nl/)!



Update last minute: use this Google Maps link (https://www.google.com/maps/place/Centrale+Bibliotheek+%2F+Muziekafdeling/@52.0915277,5.1169669,17z/data=!3m1!4b1!4m5!3m4!1s0x47c66f44d08a1b8d:0x616c592d2a9e75b1!8m2!3d52.0915244!4d5.1191556?hl=en) or look for Openbare Bibliotheek Muziekafdeling, Google Maps is confused by the address :-S



For our second meetup this year we move from Amsterdam to the historic center of Utrecht, thanks to the people of SETUP (http://setup.nl/) and the Utrecht Public Library (http://www.bibliotheekutrecht.nl/). Walk-in from 19h on, start at 19h30 sharp.



Unlike last time, there will not be food at the meetup. If you want to grab a bite together with fellow devs in Utrecht center before the meetup, post your time and place in the comments, and other people can join you by comment-replying.



There's no bar in the library, but we can bring our own stuff. So if your company wants to sponsor the meetup, let us know if you bring drinks with you (cans of beer or soda, bricks of fruit juice: anything that is handy to take with you and easily clean up afterwards). We will gladly mention your company and link to the job openings page!



Talks



A safari on the Ethereum blockchain (semi-introductory talk, Pascal Van Hecke (http://vanhecke.info))

An attempt to explain the basic ideas Ethereum in five minutes (come watch it fail ;-) and illustrate the basic ideas by going over some already deployed distributed apps on the public blockchain.



The State of the DApps (Joris Bontje (https://nl.linkedin.com/in/jorisbontje), Ethercasts (https://twitter.com/ethercasts))



For more than a year Joris has been hosting and curating a list of all the Ethereum DApps known to mankind (except some obvious scams / ponzi schemes) on http://dapps.ethercasts.com/ . In his talk he'll reflect on the kind of DApps that are being developed by the community. What trends can we see? What are the favorite languages, frameworks and licenses? And of course answer the important question: does a "Tinder for Horses" already exist?



Question and Answer session (30')



Have questions you want to see answered in the session? Post them as comment below. We'll try to answer as many as we can in half an hour, but we will prioritize those questions that are more suitable for a live session, rather than just answerable by a link to a tutorial or a documentation page!



Show and Tell



Like last time, we'll also have a number of mini-talks: 5-minute demos, or even just pitches for a project you’re working on, or planning to work on. No slides required.



Already confirmed:



• Plutus (https://plutus.it/): attempting to fit Bitcoin, Ethereum and regular fiat currency in one dao (Gerbrand van Dieijen (http://www.meetup.com/Amsterdam-Ethereum-Meetup/members/12217553))

• ...



Want to present too? Message Pascal and Joris by using the Organizers Contact button in the left navigation bar (or at the top in the mobile web app).



NOTE: this is a developer meetup, discussing Ethereum development topics. We will not be discussing broader or less technical subjects such as the impact on society, currency trading, or the relationship with Bitcoin. We warmly refer to our Bitcoin friends, some of whom have covered Ethereum-related subjects before: BTC Wednesday (http://www.meetup.com/BitcoinWednesday/), BTC Amsterdam (http://www.meetup.com/Bitcoin-Amsterdam/), BTC Embassy (http://www.meetup.com/Bitcoin-Embassy-Amsterdam/). There are also several new Blockchain-branded groups (http://www.meetup.com/find/?allMeetups=false&keywords=blockchain&radius=100&userFreeform=Amsterdam%2C+Netherlands&mcId=c1029969&mcName=Amsterdam%2C+NL&sort=recommended&eventFilter=mysugg).



New to development on Ethereum?



We welcome new people to the meetup, we do ask however that you do some effort beforehand to familiarise yourself with Ethereum. These videos (all of them embedded here too (http://www.meetup.com/Amsterdam-Ethereum-Meetup/events/228400953/)) are a good start:



• Gavin Wood, Ethereum for dummies (https://www.youtube.com/watch?v=U_LK0t_qaPo)



• Vitalik Buterin, Understanding the Ethereum Blockchain protocol (https://www.youtube.com/watch?v=gjwr-7PgpN8):



• Building a distributed application (dapp) for web developers: backend contract code (https://www.youtube.com/watch?v=seU7DykOxfc), user interaction in a Dapp browser (http://www.youtube.com/watch?v=nPpi9BPkRbo), Javascript frontend (https://www.youtube.com/watch?v=Ij5tGo8cp80)
