What is cryptocurrency?
Cardano 是以太坊联合创始人 Charles Hoskinson 于 2017 年推出，旨在与以太坊和其他去中心化应用（DApp）平台竞争。Cardano 声称比以太坊及其竞争对手更具可扩展性、高效率和安全性——与以太坊的 15-20 个 TPS 相比，它可以处理大约 250 个交易每秒（TPS）。
该网络使用 Ouroboros 家族的股权证明共识机制（POS），在该机制中，验证者必须将其 ADA 代币入股，最终按其入股资产的比例获得奖励。拥有最高资产金额的验证者被选为获胜者，并负责验证新交易，然后由其他网络验证者进行验证。
Cardano 号称是唯一一个被程序员、科学家和研究人员广泛肯定的开源区块链。自推出以来，Cardano 的原生数字货币 ADA 已经成为以太坊的一个显著竞争者，成为市值前 10 的数字货币之一。因此，购买 ADA 一直是一个热门的投资选择。ADA 的发行总量共计为 450 亿枚。
