Abstract

La présente invention concerne un système et un procédé d'échange de monnaie virtuelle numérique dotée d'une chaîne de blocs entre parties, qui conduit à faciliter un échange simple basé sur un URL sans reconnaître une adresse publique formée d'au moins 32 octets à chaque échange de monnaie virtuelle numérique dotée d'une chaîne de blocs entre parties, facilitant ainsi l'échange sans un code QR pour des paiements distincts en bitcoin, et empêchant une multiplicité d'effets désavantageux du code QR pour les paiements en bitcoin faisant intervenir un échange de monnaie virtuelle numérique dotée d'une chaîne de blocs, en même temps que le caractère malcommode de la nécessité de fournir à l'avance des codes QR pour les paiements en bitcoin de toutes les parties une par une à chaque échange de bitcoins entre les deux parties, le processus étant non seulement complexe car il est indispensable d'effectuer l'échange en photographiant le code QR lors de l'échange de monnaie virtuelle numérique dotée d'une chaîne de blocs, mais présentant également des risques de vol qui en découlent lorsque les codes QR de l'émetteur pour les paiements en bitcoin fournis à l'avance à un récepteur font l'objet d'une fuite. L'invention concerne un système comportant: des serveurs (100) de conservation de chaînes de blocs dans lesquels est installée une chaîne de blocs destinée à authentifier un échange de monnaie virtuelle numérique basée sur une chaîne de blocs en validant des informations de transaction pour un échange de monnaie virtuelle numérique dotée de la chaîne de blocs émise lorsque les informations de transaction pour un échange de monnaie virtuelle numérique dotée d'une chaîne de blocs sont émises, et servant à enregistrer les informations de transaction pour un échange de monnaie virtuelle numérique dotée d'une chaîne de blocs selon l'authentification; un serveur (200) de guidage d'échange de monnaie virtuelle numérique basée sur une chaîne de blocs qui génère et émet un URL (A) de reconnaissance de récepteur servant au guidage de telle sorte qu'un récepteur recevant la monnaie virtuelle numérique dotée d'une chaîne de blocs puisse être reconnu si un signal de demande d'échange destiné à un émetteur est émis, pour déduire le montant à verser à un récepteur d'informations concernant le montant en monnaie virtuelle numérique basée sur une chaîne de blocs conservé dans le porte-monnaie électronique d'un émetteur si un signal de profil personnel pour la reconnaissance du récepteur est émis, pour générer des informations de transaction destinées à l'échange de monnaie virtuelle numérique qui sont composées de transactions dans lesquelles le montant déduit est cumulé dans les informations concernant le montant en monnaie virtuelle numérique basée sur une chaîne de blocs présent dans le porte-monnaie électronique du récepteur, et pour les diffuser aux serveurs (100) de conservation de chaînes de blocs; le terminal (300) d'un émetteur dans lequel est installée une application côté émetteur en vue d'un échange (310) de monnaie virtuelle numérique basée sur une chaîne de blocs pour assurer un guidage de telle façon qu'un signal de demande d'échange pour un émetteur comprenant des informations concernant le montant de monnaie virtuelle numérique dotée d'une chaîne de blocs à verser et les information personnelles de l'émetteur puisse être généré, celui-ci peut être envoyé au serveur (200) de guidage d'échange de monnaie virtuelle numérique, et un récepteur auquel doit être remis l'URL (A) de reconnaissance de récepteur émis à partir du serveur (200) de guidage d'échange de monnaie virtuelle numérique peut être attribué et envoyé; et un terminal (400) de récepteur dans lequel est installée une application côté récepteur destinée à un échange de monnaie virtuelle numérique basée sur une chaîne de blocs (410) pour commander en vue de s'exécuter automatiquement lorsque l'URL (A) de reconnaissance de récepteur émis à partir du terminal (300) de l'émetteur est cliqué de façon à générer un signal de profil personnel de reconnaissance de récepteur comprenant des informations personnelles concernant le récepteur recevant la monnaie virtuelle numérique dotée d'une chaîne de blocs, et pour l'envoyer au serveur (200) de guidage d'échange de monnaie virtuelle numérique, et un procédé l'utilisant.
