Les banques au Japon commencent un essai d’émission de stablecoins via une blockchain ultra-rapide mais largement centralisée connue sous le nom de Japan Open Chain.<\/strong><\/p>

Ces essais menés par les banques seront la première expérience avec des stablecoins au Japon qui soient entièrement conformes aux lois locales<\/strong>, explique<\/a> un communiqué de presse envoyé jeudi.<\/p>

Pour l’instant, l’essai concerne les trois banques japonaises Minna no Bank, Tokyo Kiraboshi Financial Group et Shikoku Bank<\/strong>, chaque banque devant émettre son propre stablecoin. <\/p>

Preuve d’autorité<\/h2><\/span>

La blockchain que les banques utiliseront – la Japan Open Chain – a été développée par la société locale GU Technologies. La blockchain peut traiter 1 000 transactions par seconde<\/strong> et utilise un algorithme de consensus appelé Proof of Authority \/ Preuve d’autorité (PoA) au lieu des plus connus Proof-of-Work (PoW) ou Proof-of-Stake (PoS).<\/p>

Toutefois, comme c’est souvent le cas, l’augmentation de la vitesse des transactions se fait au détriment de la décentralisation.<\/strong><\/p>

Selon son site Web, la Japan Open Chain ne compte que six validateurs de réseau<\/strong>, alors que le réseau Bitcoin, par exemple, compte des dizaines de milliers d’opérateurs de nœuds. Au fil du temps, la Japan Open Chain a pour objectif de porter le nombre de validateurs à 21 entreprises, indique son site Web.<\/p>

Entièrement compatible avec Ethereum<\/h2><\/span>

La Japan Open Chain est entièrement compatible avec Ethereum<\/strong>, qui possède le plus grand écosystème au monde pour les applications décentralisées, explique le communiqué de presse.<\/p>

Il ajoute que la blockhain est compatible avec le populaire portefeuille Ethereum MetaMask<\/strong>, ce qui la rend facilement disponible pour un grand nombre d’utilisateurs de cryptomonnaies.<\/p>

L’émission de stablecoins sur la Japan Open Chain sera une \u00ab\u00a0grande opportunité commerciale\u00a0\u00bb pour les institutions financières japonaises<\/strong>, leur permettant potentiellement de traiter des transactions effectuées dans le monde entier, conclut le communiqué.<\/p>","protected":false},"excerpt":{"rendered":"
