Virtual Payment and State Channels

Perun Network

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:

Highly scalable

The Perun's channel virtualization eliminates intermediaries thereby offering nearly unlimited scalability.

Provable secure

The security of Perun is mathematically proven using state-of-the-art techniques from cryptographic research.

Privacy enhancing

Since Perun eliminates interaction with the middleman, Perun's channels naturally enhance privacy.

Cost efficient

Perun reduces costs for executing smart contracts and payments by cutting off the middleman.

Lightweight

Perun uses lightweight cryptography and can be used on almost any platform, e.g., for machine-to-machine communication.

Flexible

Perun enables completely novel applications by supporting generalized state channels.

Open Source Implementation

An open source implementation of Perun is developed in cooperation with Robert Bosch GmbH. We plan to release first version of the node software for virtual payment hubs in Q3 2018. The repository contains a proof-of-concept implementation of Perun's virtual payment hubs of length 2.
