The Perun Network is a framework that supports off-chain protocols for simple payments and generic smart contract off-chain execution. Perun's channels can be virtual, which means that off-chain transactions do not require interaction with intermediaries thereby further reducing trust, latency and costs. In additional Perun offers strong security guarantees backed up by scientific methods from cryptographic research. For further details on Perun's features visit:
This whitepaper contains the first full specification of general state channel networks that support an arbitrary number of intermediaries and allow users to run complex smart contract off-chain.
This whitepaper contains the technical description of FairSwap, a protocol for the fair exchange of digital goods using smart contracts.View the PDF
The Perun's channel virtualization eliminates intermediaries thereby offering nearly unlimited scalability.
The security of Perun is mathematically proven using state-of-the-art techniques from cryptographic research.
Since Perun eliminates interaction with the middleman, Perun's channels naturally enhance privacy.
Perun reduces costs for executing smart contracts and payments by cutting off the middleman.
Perun uses lightweight cryptography and can be used on almost any platform, e.g., for machine-to-machine communication.
Perun enables completely novel applications by supporting generalized state channels.
The Bosch research team, in collaboration with the Perun team, has developed the open source project "Direct State Transfer" (DST) as a solution to implement the Perun protocols.
Perun is currently an academic project developed jointly by the TU Darmstadt (Germany) and the University of Warsaw (Poland). It is partly founded by the German Research Foundation and the Polish National Science Center.
