Bitcoin Mining Hardware - ASIC Bitcoin Miner - Butterfly Labs Crypto-anarchism Described by Vernor Vinge, crypto-anarchy is more specifically anarcho-capitalist, employing cryptography to enable individuals to make consensual economic arrangements and to transcend national boundaries. Etymology[edit] The "crypto" in crypto-anarchism should not be confused with the use of the prefix "crypto-" to indicate an ideology or system with an intentionally concealed or obfuscated "true nature". For example, some would use the term "crypto-fascist" to describe an individual or organization that holds fascist views and subscribes to fascist doctrine but conceals their agenda so long as these doctrines remain socially unacceptable. However, Timothy C. Motives[edit] Also, the technical challenge in developing these cryptographic systems is tremendous, which interests some programmers into joining the projects. Cryptography and law[edit] Plausible deniability[edit] Crypto-anarchism relies heavily on plausible deniability to avoid censorship. Anonymous trading[edit] See also[edit]
Armory - Simple. Secure. Solid. La blockchain est la nouvelle technologie de rupture et pas seulement pour la finance Blockchain : ce mot-clé, décrivant l'une des technologies derrière le Bitcoin, crypto-monnaie emblématique, est désormais sur toutes les lèvres. Même sur celles des décideurs d'affaires, a priori non spécialistes en cryptographie. Acteurs de la micro-informatique comme Intel et IBM, banques telles Barclays, ou même opérateurs téléphoniques à l'image d'Orange... tous investissent massivement dans la R&D autour de cette technologie. Pourquoi ? Qu'est-ce au juste que la blockchain (ou chaîne de blocs) ? Un contributeur de TechCrunch, Florian Graillot, d'AXA Strategic Ventures, égrène dans un article quelques éléments de réponse, arguant même que la technologie a un sérieux potentiel de disruption (autre mot-clé du moment), et pourrait faire fleurir de multiples innovations dans son sillage. Blockchain : un système cryptographique décentralisé... La blockchain est la technologie qui se cache derrière la gestion décentralisée du Bitcoin. ... L'une des solutions possibles ?
Mastering Bitcoin - Community Outline Review Mt.Gox - Bitcoin Exchange How to Create a SSH Tunnel Through Your Seedbox IP (Proxy for Your Home PC) Faster torrents, high connectivity and seed-ability are notably the primary reasons why most of us opt to use a seedbox. Fair enough - but a seedbox (server) can be used to implement a variety of tasks that extend far beyond just torrenting. We’ll explain how you can run a SSH tunnel through your seedbox server, in order to use your seedbox’s IP address as a proxy on your local machine (home PC). And it works for most Internet apps that support SOCKS5 (web browser, IRC/MSN, even a home uTorrent client). Reasons/scenarios for how this can be applied • As a web proxy — You’ll be able to bypass any IP restrictions & firewalls, unblock certain websites, or torrent from college or work. What You’ll Need ** A seedbox server (VPS, dedi) that comes with shell (SSH) access. ** SSH client, such as PuTTY. For this demonstration we’ll be using a real server and it’s true IP address, so as to explain how[]1 to implement it through PuTTY and various webapps. Create Your SSH Tunnel 1. 2. 3. 4. 5. 6.

Les révolutionnaires du BLOCKCHAIN à l'assaut des assurances maladies! Xavier Comtesse A la conférence LIFT, cette année, les débats ont été ouvert par les révolutionnaires du BLOCKCHAIN. A l'instar de la pasionaria Primavera De Filippi ... ils ont enflamés la salle... Ainsi, on a appris -en passant- que les Blockchains allaient révolutionner les assurances! Retour sur ce sujet avec un extrait détourné d'un blog du site "Blockchain France" (cf. la source en bas de page). "Si les grandes sociétés d’assurance se penchent aujourd’hui sur la blockchain, c’est parce que cette technologie permet de "bypasser" les phases de déclaration, et de construire de nouveaux systèmes d’assurance via internet et ceci sans intermédiaire. Les "smart contracts" sont des programmes autonomes qui exécutent automatiquement les conditions et termes d’un contrat, sans nécessiter d’intervention humaine une fois démarrés. Ces mécanismes promettent des changements majeurs pour les systèmes d’assurance actuels. Des start-ups ont déjà été créées pour proposer ce genre de service.
@_stevemoore/Bitcoin How the Bitcoin protocol actually works Many thousands of articles have been written purporting to explain Bitcoin, the online, peer-to-peer currency. Most of those articles give a hand-wavy account of the underlying cryptographic protocol, omitting many details. Even those articles which delve deeper often gloss over crucial points. My aim in this post is to explain the major ideas behind the Bitcoin protocol in a clear, easily comprehensible way. We’ll start from first principles, build up to a broad theoretical understanding of how the protocol works, and then dig down into the nitty-gritty, examining the raw data in a Bitcoin transaction. Understanding the protocol in this detailed way is hard work. I’ll describe Bitcoin scripting and concepts such as smart contracts in future posts. It may seem surprising that Bitcoin’s basis is cryptography. My strategy in the post is to build Bitcoin up in stages. This strategy is slower than if I explained the entire Bitcoin protocol in one shot. First steps: a signed letter of intent
Guest Post: “The Ultimate Guide for Anonymous and Secure Internet Usage” Wednesday, April 11th, 2012 at 7:29 pm. another fine guest post by some random pastebin-using entity on the internet(s): This is a guide with which even a total noob can get high class security for his system and complete anonymity online. But its not only for noobs, it contains a lot of tips most people will find pretty helpfull. It is explained so detailed even the biggest noobs can do it^^ : Table of Contents: 1. By the time you are finished reading and implementing this guide, you will be able to securely and anonymously browse any website and to do so anonymously. In order to prepare this guide for you, I have used a computer that is running Windows Vista. I have written this guide to be as newbie friendly as possible. It is highly recommended that you close *ALL* applications running on your computer before starting. 1 : Obtaining Tor Browser The first step to becoming secure and anonymous online is to setup and install something called “TOR”. However, TOR by itself is not enough. 1.
Tutorials:Getting Started With CGminer/BFGminer - Bitcoin Mining Forum - Butterfly Labs This guide aims to get most users running Butterfly Labs hardware with either BFGMiner or CGMiner as quickly and simply as possible. It will cover mining from a Windows environment, using mining pools. Mining without using a pool (solo mining), or from another OS is very similar, though may require a few changes to these steps, or some additional set up, as in the case of mining solo. Additionally, this guide will not be covering how to set up a wallet, or transact with Bitcoin. See for more on those topics. BFGMiner and CGMiner are mining software by Luke-Jr and ckolivas, respectively. Prepare Your Hardware If you have not already, prepare a space for your mining hardware. Plug the USB cable(s) into an open port or ports on your PC or mining host. Download Mining Software The choice of mining software to use is up to you. Once your download completes, unzip or extract the files to your desktop, or preferred folder. Code: In the save dialog that appears:
Pourquoi la révolution Blockchain est en marche - 12 novembre 2015 « Tout tourne autour du blockchain » pouvait-on lire sur un panneau d’une conférence à Las Vegas en octobre. Une façon de détourner l’attention portée à bitcoin qui a mauvaise réputation vers une technologie présentée comme plus honnête et sérieuse. Les deux sont en réalité intimement liées. La crypto-monnaie numérique décentralisée appelée bitcoin est en effet controversée du fait de graves détournements malhonnêtes de son utilisation qui n’ont rien à voir avec la puissance et la sophistication intrinsèque de cette technologie, le bitcoin/blockchain. BlockChain, c'est quoi? Blockchain est une sorte de registre virtuel géant qui est distribué dans de nombreux ordinateurs interconnectés par internet y compris ceux des utilisateurs. Qui est Satoshi Nakamoto? Les algorithmes astucieux et solides ont été inventés par un mystérieux personnage Satoshi Nakamoto que personne ne dit avoir jamais rencontré et qui est peut être un avatar pour un groupe de développeurs. Comment ça fonctionne?
