This is a very basic visual introduction to the concepts behind a blockchain. We introduce the idea of an immutable ledger using an interactive web demo. If you are interested in playing with this on your own, it is available online at: http://anders.com/blockchain/ The code that runs this demo is also on GitHub: https://github.com/anders94/blockchain-demo I'm @anders94 on Twitter Donations: BTC: 1K3NvcuZzVTueHW1qhkG2Cm3viRkh2EXJp ETH: 0x84a90e21d9d02e30ddcea56d618aa75ba90331ff I'm @andersbrownworth on Steemit

C'est la techno "hype" du moment. Celle qui aurait le pouvoir de changer le monde comme le Web l'a fait ces dernières décennies. Mais, finalement, sur qu'est-ce que la Blockchain ? Comment ça marche ? que pouvons-nous faire avec ? Cette session University va nous permettre de voir en détail ce qui se cache réellement derrière le Buzz. Nous reviendrons sur le fonctionnement technique de Bitcoin, première implémentation de la Blockchain, pour ensuite décortiquer les nouvelles possibilités offertes par les plateformes comme Ethereum. Dans une seconde partie, nous détaillerons des exemples de code afin de comprendre précisément ce qu'est un smart-contract. Dans une troisième partie, nous nous intéresserons aux différents cas d'usages qui sont à l'étude où déjà implémentés et nous parlerons de...

How do you release an update to a blockchain such as BitCoin or Ethereum? Blockchains are decentralized networks where no central entity can force everyone in the network to update. Programmer explains.
The blockchain project that has gotten the most traction is Ethereum. Led by the enigmatic Vitalik Buterin and a constellation of coders and venture capitalists, Ethereum could one day run the world. But the recent hack of its Decentralized Autonomous Organization has raised doubts.
