比特币及其底层技术赢得了银行业和金融界一些最著名人物的信任和赞誉。
例如，巴西央行行长对加密货币的技术特点只说好话。
巴西中央银行行长 Fabio Araujo 表示，比特币是一项重大的“金融创新”，催生了新的重要技术和产品。
Araujo 强调了加密货币在为 Web3 概念的发展铺平道路以及促进对中央银行数字货币 (CBDC) 的研究和其他研究方面的作用。
在最近的一次活动中，中央银行行长还讨论了数字货币不断变化的格局，并补充说他的组织的主要目标之一是为比特币添加智能功能。
Araujo 透露，该国央行十多年前就开始研究加密货币的特性。
“2009年，随着推动Web3发展的比特币和分布式数据库技术的推出，我们开始加速这个过程，”他说。
“比特币计划提供工作量证明（PoW）解决方案，这对于 Web3 的基于人口的服务至关重要，”Araujo 指出。

Web3（有时称为 Web 3.0）是第三代网络技术。 Web，通常被称为万维网，是互联网的基础层，支持各种网站和应用服务。
2014 年，Polkadot 创始人和以太坊联合创始人 Gavin Wood 使用术语“Web3”来指代“基于区块链的去中心化在线生态系统”。
Web3 的概念在 2021 年获得了发展势头。在 2021 年底特别受到关注，这主要是由于比特币倡导者和知名技术专家以及公司的投资。

与此同时，Araujo 排除了使用比特币作为货币的可能性，并指出该资产的波动性是一个重大劣势。在这种情况下，中央银行行长表示 CBDC 是必要的，因为它消除了波动情况并起到了支付解决方案的作用。
他说，尽管 CBDC 利用了支持加密货币的技术，但 CBDC 并不是一种加密资产。
Araujo 指出，就像 Real 不与上市资产竞争一样，CBDC 是 Real 在加密货币运行的生态系统中的一种表达。
巴西的比特币市场和更广泛的加密货币领域正在迅速扩张。预计目前有 1000 万巴西人拥有加密货币。
巴西第二大城市里约热内卢正在积极参与吸引比特币的全球市政竞赛。
今年 1 月，该市宣布其 1% 的国库将以加密货币形式持有，并正在研究向使用比特币支付的个人提供退税的可能性。
