Each new block is added to the chain by letting all participating processes select and agree upon a single one among a number of proposed blocks. This is done through the use of a Byzantine Agrement protocol.\u003cbr\u003e\u003cbr\u003eThis paper investigates the practical use of threshold signatures and some simpler alternatives to generate a quorum certificate in the context of permissioned blockchain protocols based on Byzantine Agreement. In particular, we take a close look at the HotStuff procotol and how it generates its quorum certificates.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ：\u003c\/strong\u003e718-723p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別：\u003c\/strong\u003e英語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePDFファイルサイズ：\u003c\/strong\u003e528Kバイト\u003c\/p\u003e","brand":"IEEJ-PDF","offers":[{"title":"PDFダウンロード（一般価格440円\/会員価格220円） \/ A4 \/ 5","offer_id":47942092620015,"sku":"IEEJ-BTC205OS011001-PDF","price":440.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-PDF_bumontaikai_9e9d0a82-df19-469c-8361-fb0d6f5db668.png?v=1773062644","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-btc205os011001","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
