This postponement has real-life monetary consequences, so while SPOs and community members can help to spread the word, official announcements on <a href=\"https:\/\/www.cardano.org\/\" style=\"background-color: rgb(255, 255, 255);\">cardano.org&nbsp;<\/a>or similar will inspire much more confidence.<br><br><\/div>\n<div>Cardano has no CEO. With decentralization, the official channel of Cardano gospels needs to shift away from Charles. ADA holders should not need to sift through Twitter, YouTube, Telegram and reddit just to find the information they need.<\/div>\n<div>&nbsp;<\/div>\n<div>The postponement of SPO block-making is a little disappointing, since KOPI&#8217;s system has been purring along smoothly and raring to go. But we stand by our principle of fairness and community, and re-iterate that the well-being of the Cardano eco-system remains top priority.<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>On d and alpha The d parameter represents the proportion of blocks made by stake pool operators (SPOs), not by the OBFT protocol.
