Based on state channels

The first component of Perun’s off-chain framework are State Channels. State Channels allow users to execute massive amounts transactions off-chain, while the security is backed by the underlying blockchain. The soundness of our protocols has been analyzed with cutting edge methods of cryptographic research.

Off-chain 

technology

Perun’s technology works on top of any existing blockchain to enable fast, secure, and scalable transactions between an arbitrary number of parties. Transactions are executed off-chain (not recorded on the ledger) for as long as all parties are in agreement. In case of dispute, the blockchain acts as a judge between the parties.

Our technology has been published at leading cryptographic conferences.
