论文摘要
我们解决了销售数字内容的在线市场中公平性和透明度的问题，在那里所有各方都没有积极参与交易。我们介绍了Vader的设计，实施和评估，Vader是多方公平数字交易所的高度可扩展解决方案，将可信赖的区块链与智能协议设计和激励性方案结合在一起。我们在Hyperledger织物上原型VADER原型Vader，并在跨越四大洲的五个公共云数据中心的逼真的测试床上广泛评估了我们的系统。我们的结果表明，与基线解决方案相比，Vader在中位数中仅增加了16％的开销，同时显着胜过基于天真的区块链的解决方案，该解决方案的开销增加了764％。
We address the problem of fairness and transparency in online marketplaces selling digital content, where all parties are not actively participating in the trade. We present the design, implementation and evaluation of VADER, a highly scalable solution for multi-party fair digital exchange that combines the trusted execution of blockchains with intelligent protocol design and incentivization schemes. We prototype VADER on Hyperledger Fabric and extensively evaluate our system on a realistic testbed spanning five public cloud datacenters, spread across four continents. Our results demonstrate that VADER adds only minimal overhead of 16% in median case compared to a baseline solution, while significantly outperforming a naive blockchain based solution that adds an overhead of 764%.
