论文摘要
分散的云计算平台使个人能够以对等方式提供和租用资源。他们必须将资源从多个卖家分配给多个买家，并得出与双方利益和能力相匹配的价格。任务过程必须分散，公平和透明，但也必须保护买家的隐私。我们提出了一个分散的平台Pastrami，可以通过支持多项目拍卖来实现大量卖方和竞标者之间的物品和价格任务。 Pastrami使用阈值盲目签名和承诺计划来提供强大的隐私保证，同时使投标人负责。它利用以太坊区块链具有可唤起性，将有效的脱链计算与新颖的链链证明相结合。我们使用Filecoin工作负载对五香熏牛肉的评估表明，它有能力有效地在数千名买卖双方之间进行可信赖的任务。
Decentralised cloud computing platforms enable individuals to offer and rent resources in a peer-to-peer fashion. They must assign resources from multiple sellers to multiple buyers and derive prices that match the interests and capacities of both parties. The assignment process must be decentralised, fair and transparent, but also protect the privacy of buyers. We present PASTRAMI, a decentralised platform enabling trustworthy assignments of items and prices between a large number of sellers and bidders, through the support of multi-item auctions. PASTRAMI uses threshold blind signatures and commitment schemes to provide strong privacy guarantees while making bidders accountable. It leverages the Ethereum blockchain for auditability, combining efficient off-chain computations with novel, on-chain proofs of misbehaviour. Our evaluation of PASTRAMI using Filecoin workloads show its ability to efficiently produce trustworthy assignments between thousands of buyers and sellers.
