论文摘要
我们构建一个保护隐私，分布式和分散的市场，当事方可以在该市场上交换代币的数据。在这个市场中，买卖双方在区块链中进行交易，并与第三方（名为Notary）互动，他有能力保证数据的真实性和完整性。 我们引入了一个数据token交换的协议，在该协议中，双方都没有获得的信息超过其支付的信息，并且交换是公平的：双方双方都获得了对方的项目，或者都没有。设置后不需要第三方参与，也无需解决争议。
We construct a privacy-preserving, distributed and decentralized marketplace where parties can exchange data for tokens. In this market, buyers and sellers make transactions in a blockchain and interact with a third party, called notary, who has the ability to vouch for the authenticity and integrity of the data. We introduce a protocol for the data-token exchange where neither party gains more information than what it is paying for, and the exchange is fair: either both parties gets the other's item or neither does. No third party involvement is required after setup, and no dispute resolution is needed.
