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…
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…
Sustained Space Complexity
Joel Alwen, Jeremiah Blocki, Krzysztof Pietrzak
Memory-hard functions (MHF) are functions whose evaluation cost is dominated by memory cost. MHFs are egalitarian, in the sense that evaluating them on dedicated hardware (like FPG…
Non-Uniform Attacks Against Pseudoentropy
Krzysztof Pietrzak, Maciej Skorski
De, Trevisan and Tulsiani [CRYPTO 2010] show that every distribution over -bit strings which has constant statistical distance to uniform (e.g., the output of a pseudorandom gen…
Condensed Unpredictability
Maciej Skorski, Alexander Golovnev, Krzysztof Pietrzak
We consider the task of deriving a key with high HILL entropy from an unpredictable source. Previous to this work, the only known way to transform unpredictability into a key that…
