Blockchain et assurances – Blockchain France. Ce que les assurances distribuées et les smart contracts vont bouleverser dans les pratiques assurantielles Le monde de la finance s’intéresse de près à la blockchain. Mais loin de cantonner son potentiel au milieu bancaire, cette nouvelle technologie intéresse également le secteur de l’assurance. Des entreprises comme Lloyds ou Allianz France ont déjà manifesté leur intérêt et leur volonté de lancer des expérimentations sur la blockchain. Plus récemment, Axa a investi 55 millions de dollars dans la start-up Blockstream, dont les développeurs sont les plus gros contributeurs au protocole Bitcoin et qui permettra, entre autres, l’interopérabilité entre différentes blockchains.
Ethereum: Bitcoin Plus Everything – Medium. By Mike Goldin This article is the sequel to Just Enough Bitcoin For Ethereum.
Check that out first if you haven’t already. All the background you need (and neither more nor less!) To begin understanding Ethereum is there. Remember the first time you began using objects in a programming language? To get started, read the three sections in the Ethereum white paper on accounts, transactions and messages. Now You’re Thinking With Contracts! Smart contracts are code that is stored and executed on a blockchain. Ethereum opens the scope of what these programs can be beyond simple transfers of sums to anything which can be programmed on a Turing machine. Ethereum enables this complexity by placing a virtual machine (called the Ethereum Virtual Machine, or EVM) in every node on the network.
Imagine a trivial program stored at an account which accepts a number as input, adds that number to a running sum and overwrites the previous sum with the new one. The Price Of Gas. A 101 Noob Intro to Programming Smart Contracts on Ethereum – Medium. Originally published at consensys.github.io/developers (where some of the code formatting might be easier to read).
Some people say Ethereum is too logic-heavy and hard to use, but here’s a write-up to give you a feel for building smart contracts and applications with it. Tools, wallets, applications and the ecosystem are still in development and it’ll get easier! Part I is an overview of key terms and discusses Ethereum Clients and Smart Contract Languages.Part II discusses overall workflow and some current DApp Frameworks and Tools andPart III is the Programming Part, a quick walkthrough of writing tests and building a DApp for a smart contract using Truffle.
Part I. Intro If you’re new to all this cryptocurrency stuff, including Bitcoin and how it works, check out the first couple chapters of Andreas Antonopoulos’ Bitcoin Book to dip your toe in the water. If you start getting into some murky sections and would rather build something to get familiar first, then just read on. Node. Gas. Scalable Enterprise Blockchain Infrastructure. Ujo Music. Today, an artist’s identity is thinly spread across many online music services.
These platforms are walled-off and disconnected, making it difficult for innovators to access information that could be used to create services that allow fans to experience music in new ways. Ujo takes a different approach by building an open music ecosystem on the Ethereum blockchain. The blockchain provides a shared infrastructure for all music services so they can focus on providing value to their users. The shared infrastructure also supplies a basis for persistent artist identity. Artists own and control their works, and can frictionlessly migrate to and from services. A neutral backbone would be greatly beneficial for the music industry; however, adoption remains a challenge.

Cet article constitue une première introduction à Ethereum. Il traite de façon la plus pédagogique possible des concepts de blockchain, smart contracts et DAO, sans entrer dans des détails techniques. Si vous souhaitez en savoir plus sur le fonctionnement technique de la blockchain Ethereum, je vous recommande la très intéressante suite d’articles de Gautier Marin-Dagannaud, en cours de rédaction.
Ethereum, un ordinateur mondial En une phrase, Ethereum est : un ordinateur mondial, que n’importe qui peut programmer et utiliser comme il le souhaite. Cet ordinateur est toujours allumé, il est très sécurisé, et tout ce qui est fait à l’aide de cet ordinateur est public. Cette infographie permet d’avoir un premier aperçu de son fonctionnement. « Ethereum expliqué à ma mère ». Infographie réalisée par Angelo Milan (@angelomilan) et traduite pour le site Ethereum France.
