Our Technology

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.



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.
