论文摘要
在分散的环境中，交换资源要求用户讨价还价，直到找到协议为止。此外，人类协议涉及协作和自私的行为以及通常引起循环性的结合，使对交换请求的评估变得复杂。我们介绍了MUAC，这是一种政策语言，允许用户孤立地陈述他们开放的条件以授予其资源以及需要回报的内容。在MUAC中，自动评估交换请求，并保证唯一会发生的交换是相互满足用户条件的交易所。此外，MUAC可以用作防止用户作弊的执行机制。作为概念的证明，我们实施了一个区块链智能合约，使用户可以交换其无可杀伤的令牌。
In a decentralized environment, exchanging resources requires users to bargain until an agreement is found. Moreover, human agreements involve a combination of collaborative and selfish behavior and often induce circularity, complicating the evaluation of exchange requests. We introduce MuAC, a policy language that allows users to state in isolation under which conditions they are open to grant their resources and what they require in return. In MuAC, exchange requests are evaluated automatically with the guarantee that the only exchanges that will take place are those that mutually satisfy users' conditions. Moreover, MuAC can be used as an enforcement mechanism to prevent users from cheating. As a proof of concept, we implement a blockchain smart contract that allows users to exchange their non-fungible tokens.
