由於傳統的加油付款程式文書工作繁重且用時長,同時無法預測航班所需燃料的確切數量,因此航空公司需要向燃料運營商支付更多的資金,購買更多的燃料,以確保燃料充足。
據國外媒體報導,為提高飛機加油和支付過程的透明度,俄羅斯西伯利亞航空公司和其燃料供應商已經成功完成了區塊鏈加油專案“智慧燃料”試點工作。該專案的應用程式基於區塊鏈框架Hyperledger Fabric研發而成,執行過程中,啟動可執行的分散式代碼合同或智慧合約模組,讓初始燃料量以及成本能在區塊鏈平臺上實現透明視覺化。當需要為飛機提供燃料時,飛行員要求的確切燃料量和燃料成本就會被發送到航空公司合作的銀行,並告知其所需的資金。加油完成後,資金會自動扣除,並立即向所有相關方確認。
據介紹,新的區塊鏈驅動系統使整個加油及付款過程自動化,得以讓支付時間大大縮短。該系統能夠在幾秒鐘內處理加油付款,而傳統的付款交易通常需要4到5天。目前,在俄羅斯摩爾曼斯克國際機場,已有100多個西伯利亞航空公司航班試用了這一平臺。
隨著未來應用場景的不斷增加,區塊鏈技術可能會應用於越來越重要的領域,因此怎麼保證資訊安全是目前最需要引起重視的。那麼問題來了,這種完全在區塊鏈上,全自動完成付款的操作真的安全嗎?理論上來說,不能說是100%的安全。如果區塊鏈受到攻擊或者監管機制不完善,都會導致區塊鏈出現安全隱患和漏洞。假設有同等算力資源的1萬人使用同一個區塊鏈,其中超過5000人達成一個共識,要攻擊區塊鏈,那這種攻擊就會成功破壞之前的各方約定。當然這種情況一般很難做到。
目前,使用區塊鏈技術完成支付的應用場景並不鮮見,比如在跨境支付、供應鏈管理(協作與溯源)、跨境貿易、金融服務等場景都有著不錯的應用。在區塊鏈框架方面,目前我國使用的基本都是國際上的開源系統。我國應該自主研發區塊鏈框架,每行代碼都應由我們自主完成。目前相關團隊正在進行這項工作,只有實現了基礎框架的自主可控,區塊鏈應用場景才能實現真正的安全。

Commercial floor polishing will ready your office for the Monday rush, or we can send the office floor care team every day when it is very busy in your facility. (your info stays private with us) Hardwood flooring has been around us for centuries. But in the past two decades, laminate flooring has taken up the market by storms. Both the flooring traditionally uses hardwood as the base. Therefore, they are as sturdy as horses and also beautiful to look at. However, cleaning and maintaining them is harder than you think. The debris trapped inside the flooring doesn’t come off with basic vacuuming and mopping. We at AVS Carpet Cleaning provide professional hardwood and laminate cleaning services in the San Diego area. http://cumgirls.club/blog/community/profile/weldonmacvitie/ As we mentioned earlier, a local cleaning service can charge you either per hour or per square foot basis.

Many domestic and international tourists feel compelled to visit this landmark in Boston for its rich history and story-telling audiovisuals which truly make for an unforgettable experience. Housekeeper Remember that a cleaning company is not there to pick up after you. If your floor is cluttered with toys, books and games, your cleaner will not be able to vacuum it. If you hire an independent cleaner, they may perform this task but it will take more time and therefore will cost you more.

Während die Entwickler von Evolution Gaming bekannt dafür sind, einige der populärsten Roulette-Varianten auf den Markt gebracht zu haben, unterscheidet sich das Auto Roulette Spiel doch ganz wesentlich von den anderen Vertretern: Es ist kein Live Dealer involviert, der sich per Video-Übertragung aus einem Studio meldet, wo an einem Roulette-Tisch die Drehungen ausgeführt werden. Stattdessen haben wir es hier mit einem Roulette-Rad zu tun, das so fortschrittlich und kraftvoll ist, dass es wortwörtlich das Spiel antreibt. Das mag sich für ein Live Casino Spiel erst einmal kontraproduktiv anhören. Allerdings hat dieses Merkmal zahlreiche Vorteile, die wir im Anschluss näher beleuchten werden. Live Roulette im Online Casino ist ein besonderes Erlebnis. Damit nicht nur beim Spielangebot alles passt, sondern Echtgeld Spieler rundum zufrieden sein können, testen wir alle Anbieter sehr genau. Nur wenn bei Sicherheit, Zahlungsmethoden, Fairness, Kundenservice, Bonus Programm und Mobile Casino alles stimmt, sprechen wir eine Empfehlung aus. Die besten Online Casinos für Live Casino Games und Live Roulette entnehmen Sie unserer Top Liste. http://juanocasio.aegcloud.pro/isla-de-santaclara/community/profile/luciemosely1556/ Wildz Erfahrungen zu sammeln, macht nicht nur Spaß, sondern sorgt auch für Top-Gewinne! Außerdem kommt diese Online Spielhalle kommt mit einer lustigen Wildz Oma daher und besticht mit genialen Bonusangeboten und einem tollen Willkommensbonus. Aber hält die Aufmachung auch, was sie verspricht? Ja! Meine Wildz Erfahrungen waren durchweg positiv und die angesagte Spielhalle kann definitiv mit den besten Anbietern mithalten. Eine klare Empfehlung. Unseriöse Anbieter oder Echtgeld Casino Apps ohne gültige Lizenz habe ich nicht berücksichtigt. Die neuen mobilen Casino Apps in dieser Liste sind lizenziert und sicher. Besonders bei neuen Spielbanken ist die Lizenzierung wichtig. Schließlich liegen im Internet nicht genügend Erfahrungen und Testberichte vor, um sich ein Bild machen zu können.
