TL;DR

The default HTTP connection is usually closed after each request has been completed, meaning that the server closes the TCP connection after delivering the response. In order to keep the connection open for multiple requests, the keep-alive connection header can be used. All modern browsers use persistent connections as long as the server is willing to cooperate. You may also use HTTP/1.1, where Keep-Alive is implemented differently and the connections are kept open by default unless the response contains a “Connection: close” header.

La BlockChain est une technologie de transactions partagées, ou non, par des utilisateurs. Comme toute technologie, la BlockChain a besoin d’outils de modélisation pour guider la conception de projets et chaque partie du projet a besoin de pouvoir modéliser avec le même outil de manière à être compris par toutes les personnes travaillant sur le projet (les personnes techniques, les chefs de projets, les maîtrises d’ouvrage, …). Tout comme une illustration permet de s’accorder sur une interface, tout comme l’UML permet de s’accorder sur le fonctionnement d’un logiciel, il est nécessaire de s’accorder sur les rôles des utilisateurs de la BlockChain ainsi que sur les différents types d’interactions.
