Because our non-geek friends expect us to at least understand how this thing works: a Bitcoin edition!

16.30 Doors open

17.00 Talk: Peek into the mind of a Bitcoin miner (Pascal Van Hecke)

So bitcoin is a peer-to-peer network and protocol, but what does that actually mean? So let's do a bit of roleplaying as nodes on the bitcoin network to get to understand the basic terms: transactions, addresses, mining, the blockchain, confirmations, doublespending, the 51% attack...


18.00 Talk: The state of the Bitcoin (Bas de Lange)

It all started with a whitepaper http://bitcoin.org/bitcoin.pdf posted on the web in November 2008, just 5 years ago. Bas de Lange ( http://bitcoinobserver.com/ ) will paint us a picture of the massive developments since (also in the Netherlands): software and services used, altcoins, mining pools and dedicated hardware, and will talk about some exciting new developments: the bitcoin payment protocol, contracts on the blockchain, smart property.

Lightning talks:

• Talk 1: how to secure your Bitcoin with cold storage (no, not your regular fridge), Robert Reinder Nederhoed (http://www.meetup.com/devhaag/members/4216506/)

As usual, we have lightning talks: (max 5 minutes/speaker - slides are optional). Given this is a bitcoin edition, it would be nice if we would have some people from the Bitcoin community present their project. Starting a mining pool? Building a Bitcoin ATM? Come and present an early version for our geeky audience! (contact @pascalvanhecke on Twitter if you want a spot)


19.30 Closing

What to bring

Come with some post-its, colored pen(cil)s, a Bitcoin wallet app (Multibit (https://multibit.org/) for desktop, Bitcoin Wallet for Android (https://play.google.com/store/apps/details?id=de.schildbach.wallet) - or even Litecoin Wallet for Android (https://play.google.com/store/apps/details?id=de.schildbach.wallet_ltc) - BlockChain for iPhone (https://blockchain.info/nl/wallet/iphone-app) - limited functionality).

NO HAVE ANY BITCOIN? Send Bas an email (devhaag apekrul bitcoinference dot com) and he will send you a fraction of a bitcoin to play with.


For EUR 75 or 1/8th of a Bitcoin, you buy the attendees some beer and cookies - AND you can shamelessly plug your business during the event. Update: BitMyMoney (https://bitmymoney.com/) will be sponsoring drinks!

Think this meetup was announced way too late?

You are so totally right about that. The reason: current crew (http://www.meetup.com/devhaag/members/?op=leaders) is getting old and slow! (Work, and kids, and rheumatism...). So DIY (http://www.meetup.com/devhaag/pages/devhaag_DIY/) :-) and give us a shout. (http://www.meetup.com/devhaag/suggestion/)
