论文摘要
我们提出了乒乓交换：不需要托管或中间值得信赖的第三方的代币或加密货币的纯净对等交叉链互换机制。唯一的技术要求是能够在两个区块链协议中打开单向支付渠道。这允许匿名加密货币交易无需集中式交易，也可以在Defi平台中进行dex，也没有受到惩罚的多符号托管系统。无需桥接平台，可以执行直接对等交叉链互换。这样可以创建非习惯交易所，并成为全球的代币或加密货币对点对点市场。如果银行包含简单的支付渠道功能，则可以与法定货币进行乒乓互换。一些即时应用程序是闪电网络频道的简单而快速的重新平衡，并在SmartChains中包装令牌。
We propose Ping-Pong Swaps: A secure pure peer-to-peer crosschain swap mechanism of tokens or cryptocurrencies that does not require escrow nor an intermediate trusted third party. The only technical requirement is to be able to open unidirectional payment channels in both blockchain protocols. This allows anonymous cryptocurrency trading without the need of a centralized exchange, nor DEX's in DeFi platforms, nor multisignature escrow systems with penalties. Direct peer-to-peer crosschain swaps can be performed without a bridge platform. This enables the creation of non-custodial exchanges and also a global peer-to-peer market of pairs of tokens or cryptocurrencies. Ping-pong swaps with fiat currency is possible if banks incorporate simple payment channel functionalities. Some immediate applications are simple and fast rebalancing of Lightning Network channels, and wrapping tokens in smartchains.
