PASTRAMI: Privacy-preserving, Auditable, Scalable Trustworthy Auctions for Multiple Items [article]

Michał Król, Alberto Sonnino, Argyrios Tasiopoulos, Ioannis Psaras, Etienne Rivière
2020 arXiv   pre-print
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.  ...  It leverages the Ethereum blockchain for auditability, combining efficient off-chain computations with novel, on-chain proofs of misbehaviour.  ...  Finally, PASTRAMI achieves high Scalability and supports large number of users and items while maintaining low overall cost of running auctions for the platform and its participant.  ...
