论文摘要
一种选择是两方之间的财务协议，以交易两个资产。一方有权在指定的终止时间之前完成交换的权利，但没有义务。在当今的金融市场中，一种选择本身可以被视为可以转让的资产：虽然有活跃的选择权，但一个方可以将其权利（或义务）出售给另一方。今天的区块链支持跨链原子交换协议形式的简单选项，其中一个方可以选择是否完成交换。但是，这些跨链协议实现的选项是不可转让的。本文提出了针对可转让的跨链选项的新颖分布式协议，期权所有者和提供商都可以将其头寸出售给第三方。该协议确保没有任何一方都能被欺骗，没有未经授权的一方可以干预，并且如果买卖双方忠实地遵守该协议，转让会成功。
An option is a financial agreement between two parties to trade two assets. One party is given the right, but not the obligation, to complete the swap before a specified termination time. In todays financial markets, an option is considered an asset which can itself be transferred: while an option is active, one party can sell its rights (or obligations) to another. Todays blockchains support simple options in the form of cross-chain atomic swap protocols where one party has the choice whether to complete the swap. The options implemented by these cross-chain protocols, are not, however, transferable. This paper proposes novel distributed protocols for transferable cross-chain options, where both option owners and providers can sell their positions to third parties. The protocol ensures that none of the parties can be cheated, that no unauthorized party can interfere, and that the transfer succeeds if the buyer and seller faithfully follow the protocol.
