论文摘要
在印度，在2016年取消货币化演习后，数字付款变得非常受欢迎。其中，使用PayTM钱包和UPI（统一付款接口）的交易量增加了。由于COVID-19，大流行造成的锁定已进一步促进了这一趋势。并排的是，比特币等加密货币也正在吸引。许多国家正在考虑通过其中央银行发行数字货币。在本文中，我们提出了一种新颖的分散数字货币系统（DDC），该系统利用Merkle Hash-Trees作为身份验证的数据结构。 DDCS使用了无分类帐，分布式，点对点架构。我们命名拟议的货币$δ$ -Money。 $δ$ -Money旨在替代实体货币，并具有与加密货币相媲美的内置安全功能。使用$δ$ - 货币的交易以分离的方式进行，但在事后核对中进行。代替中央银行发行的数字货币（CBDC），我们设想了一个方案，其中多个支付银行发行了具有稳定估值的数字货币，而不会受到波动性或多年生贬值的影响。
In India, post the demonetization exercise in 2016, digital payments have become extremely popular. Among them, the volume of transactions using Paytm wallets and UPI (Unified Payment Interface) have grown manifold. The lockdowns due to COVID-19 Pandemic have furthered this trend. Side by side, crypto-currencies such as bitcoin are also gaining traction. Many countries are considering issuing a Digital Currency via their Central Banks. In this paper, we propose a novel Decentralized Digital Currency System (DDCS) that makes use of Merkle Hash-Trees as Authenticated Data Structures. DDCS uses a Ledger-less, distributed, peer-to-peer architecture. We name the proposed currency $δ$-Money. $δ$-Money is intended as a replacement for physical currency and has in-built security features that rival crypto-currencies. Transactions using $δ$-Money happen in a disintermediated manner but with post-facto reconciliation. In place of Central Bank-issued Digital Currency (CBDC), we envisage a scenario where multiple Payment Banks issue digital currencies that have stable valuations without being subject to either volatility or perennial devaluation.
