论文摘要
区块链技术赋予加密货币的安全，无信任和隐私的交易。但是，现有的基于区块链的交易平台仅支持使用数字资产（例如NFTS）的加密货币。尽管几家支付服务提供商已经开始接受加密货币作为有形商品的付款方式（例如签证，贝宝），但客户仍然需要信任并将其私人信息交给集中的电子商务平台（例如，亚马逊，eBay）。为了在加密货币和真实商品之间实现无信任和隐私性的交易，我们提出了Spender，这是一个基于智能合同的平台，用于安全和隐私权分散的P2P电子商务。我们平台的设计具有各种有利的功能，并带来了无限的未来潜力。此外，我们的平台提供了一个完整的范式，用于在区块链上设计现实世界中的Web3基础架构，该基础链扩大了应用程序范围并利用了加密货币的内在值。该平台已在Terra生态系统上构建和测试，我们计划以后开放代码。
The blockchain technology empowers secure, trustless, and privacy-preserving trading with cryptocurrencies. However, existing blockchain-based trading platforms only support trading cryptocurrencies with digital assets (e.g., NFTs). Although several payment service providers have started to accept cryptocurrency as a payment method for tangible goods (e.g., Visa, PayPal), customers still need to trust and hand over their private information to centralized E-commerce platforms (e.g., Amazon, eBay). To enable trustless and privacy-preserving trading between cryptocurrencies and real goods, we propose SPENDER, a smart-contract-based platform for Secure and Privacy-PresErviNg Decentralized P2P E-commeRce. The design of our platform enables various advantageous features and brings unlimited future potential. Moreover, our platform provides a complete paradigm for designing real-world Web3 infrastructures on the blockchain, which broadens the application scope and exploits the intrinsic values of cryptocurrencies. The platform has been built and tested on the Terra ecosystem, and we plan to open-source the code later.
