CoinDesk专栏作家:美国不用担心在CBDC竞赛中落后:CoinDesk专栏作家JP Koning刊文称,美国不用担心在央行数字货币(CBDC)竞赛中落后。这是因为发行央行数字货币没有先发优势。对于许多产品来说,抢占先机对获得品牌优势很重要。但央行数字货币的特点是后发优势,而不是先发优势。最好还是坐下来,向那些缺乏耐心的央行学习。[2020/11/3 11:28:57]

动态 | Scribd曾因澳本聪注册版权暂时撤掉Coindesk上传的比特币白皮书:据CoinDesk报道,澳本聪(Craig Wright)对原始比特币白皮书的版权注册已开始产生涟漪效应。5月28日,提供在互联网上发布可下载文件服务的Scribd通知CoinDesk已经撤下了CoinDesk上传的比特币白皮书副本。电子邮件显示,Scribd的BookID版权保护系统已经其禁止访问比特币白皮书,但这并不一定意味着发生了侵权行为。据悉,尽管澳本聪为白皮书注册了版权,但除非有人在法庭上对版权提出质疑,否则该版权注册毫无意义。然而由于像BookID这样的系统很可能会对美国版权数据库进行ping操作,因此该文件的副本将被公共服务处理。此后,Scribd法律运营经理Jason Bentley表示,该服务的团队已经审查了CoinDesk的回复,并确定Scribd的BookID版权保护系统可能错误地将该内容标识为侵权。Scribd已经恢复了该内容和相关指标。[2019/6/1]
