Decentralized marketplace applications demand fast, cheap and easy-to-usecryptocurrency payment mechanisms to facilitate high transaction volumes. Thestandard solution for off-chain payments, state channels, are optimized forfrequent transactions between two entities and impose prohibitive liquidity andcapital requirements on payment senders for marketplace transactions. Wepropose PayPlace, a scalable off-chain protocol for payments between consumersand sellers. Using PayPlace, consumers establish a virtual unidirectionalpayment channel with an intermediary operator to pay for their transactions.Unlike state channels, however, the PayPlace operator can reference thecustodial funds accrued off-chain in these channels to in-turn maketamper-proof off-chain payments to merchants, without locking up correspondingcapital in channels with merchants. Our design ensures that new payments madeto merchants are guaranteed to be safe once notarized and provably mitigateswell-known drawbacks in previous constructions like the data availabilityattack and ensures that neither consumers nor merchants need to be online toensure continued safety of their notarized funds. We show that the on-chainmonetary and computational costs for PayPlace is O(1) in the number of paymenttransactions processed, and is near-constant in other parameters in mostscenarios. PayPlace can hence scale the payment throughput for large-scalemarketplaces at no marginal cost and is orders of magnitude cheaper than thestate-of-art solution for non-pairwise off-chain payments, Zero KnowledgeRollups.
