论文摘要
我们提出了对比特币上可及代币的安全有效实施。我们的技术基于比特币脚本语言的较小扩展，该语言允许交易中的支出条件取决于邻居交易。我们表明我们的实现是计算上的声音：也就是说，对手只能以可忽略的概率使代币与他们的理想功能不同。
We propose a secure and efficient implementation of fungible tokens on Bitcoin. Our technique is based on a small extension of the Bitcoin script language, which allows the spending conditions in a transaction to depend on the neighbour transactions. We show that our implementation is computationally sound: that is, adversaries can make tokens diverge from their ideal functionality only with negligible probability.
