Perun: Virtual Payment Channels over Cryptographic Currencies
Stefan Dziembowski, Lisa Eckey, Sebastian Faust und Daniel Malinowski
In: IEEE Symposium on Security and Privacy (S&P), 2019

In this work, we introduce Perun, a system that combines payment channels allowed on cryptocurrencies. We present a new technique called “virtual payment channels” which avoids interaction with intermediaries for every single payment.

IEEE S&P will be held May 20-22, 2019 in San Francisco, USA.
