Eating sandwiches: Modular and lightweight elimination of transaction reordering attacks
Orestis Alpos, Ignacio Amores-Sesar, Christian Cachin +1
Traditional blockchains grant the miner of a block full control not only over which transactions but also their order. This constitutes a major flaw discovered with the introductio…
Lightning Creation Games
Zeta Avarikioti, Tomasz Lizurej, Tomasz Michalak +1
Payment channel networks (PCNs) are a promising solution to the scalability problem of cryptocurrencies. Any two users connected by a payment channel in the network can theoretical…
Cross-client Label Propagation for Transductive and Semi-Supervised Federated Learning
Jonathan Scott, Michelle Yeo, Christoph H. Lampert
We present Cross-Client Label Propagation(XCLP), a new method for transductive federated learning. XCLP estimates a data graph jointly from the data of multiple clients and compute…
Online Admission Control and Rebalancing in Payment Channel Networks
Mahsa Bastankhah, Krishnendu Chatterjee, Mohammad Ali Maddah-Ali +3
Payment channel networks (PCNs) are a promising technology to improve the scalability of cryptocurrencies. PCNs, however, face the challenge that the frequent usage of certain rout…
Wiser: Increasing Throughput in Payment Channel Networks with Transaction Aggregation
Samarth Tiwari, Michelle Yeo, Zeta Avarikioti +3
Payment channel networks (PCNs) are one of the most prominent solutions to the limited transaction throughput of blockchains. Nevertheless, PCNs suffer themselves from a throughput…
Weighted Packet Selection for Rechargeable Links: Complexity and Approximation
Stefan Schmid, Jakub Svoboda, Michelle Yeo
We consider a natural problem dealing with weighted packet selection across a rechargeable link, which e.g., finds applications in cryptocurrency networks. The capacity of a link $…
HIDE & SEEK: Privacy-Preserving Rebalancing on Payment Channel Networks
Zeta Avarikioti, Krzysztof Pietrzak, Iosif Salem +3
Payment channels effectively move the transaction load off-chain thereby successfully addressing the inherent scalability problem most cryptocurrencies face. A major drawback of pa…
LightPIR: Privacy-Preserving Route Discovery for Payment Channel Networks
Krzysztof Pietrzak, Iosif Salem, Stefan Schmid +1
Payment channel networks are a promising approach to improve the scalability of cryptocurrencies: they allow to perform transactions in a peer-to-peer fashion, along multi-hop rout…
StarCraft II: A New Challenge for Reinforcement Learning
Oriol Vinyals, Timo Ewalds, Sergey Bartunov +22
This paper introduces SC2LE (StarCraft II Learning Environment), a reinforcement learning environment based on the StarCraft II game. This domain poses a new grand challenge for re…
