De nombreuses personnes ont entendu parler des smart contracts. Créés à partir de la blockchain Ethereum, qu’apportent-ils réellement et comment fonctionnent-ils ? Coinhouse<\/b> vous explique au travers d’un exemple concret ce concept et les innovations qu’il concrétise.<\/p>

La fonctionnalité la plus importante d’Ethereum<\/a> est la possibilité d’utiliser des smart contracts. Dans cet article, nous allons détailler le fonctionnement de cette technologie, ses usages et ses limites, afin de la rendre compréhensible au plus grand nombre.<\/p>

La blockchain Bitcoin pour des transactions simples<\/h3>

En utilisant la technologie Bitcoin<\/a>, on utilisera la plupart du temps des transactions simples, via l’envoi de bitcoins d’une adresse à une autre. Il est aussi possible d’utiliser des mécanismes plus complexes, comme la multi-signature. Mais ces fonctionnalités restent limitées et ne permettent pas l’exécution d’algorithmes complexes.<\/p>

L’introduction de la condition dans l’exécution d’une action<\/h3>

Concept formulé en 1996 par le développeur Nick Szabo, un smart contract est un programme informatique enregistré sur une Blockchain, la plupart du temps Ethereum. Il permet de déclencher des transactions conditionnelles dont l’exécution dépend de facteurs définis à l’avance via un algorithme. Les smart contracts s’exécutent grâce aux ethers que vous pouvez acheter et vendre sur notre plateforme Coinhouse, tout comme la plupart des tokens adossés aux projets créés à partir de smart contracts. Ces ethers servent de carburant consommé au fur et à mesure de l’exécution du programme.<\/p>

Prenons un exemple : on veut réaliser un projet de crowdfunding, avec les meilleures garanties de sécurité, et avec un montant minimum en dessous duquel le projet sera annulé. On demande à des souscripteurs d’envoyer de l’argent sur une période d’un mois. Si le projet récolte plus de 1000€, l’argent est versé aux gestionnaires du projet, sinon les souscripteurs seront intégralement remboursés.<\/p>
