Abstract
This specification describes a system and method that enables multiple blockchain users to exchange their transactions before diffusion over the blockchain network in order to blur the link between the IP address of the transaction generated by a user and the user's blockchain address in the transaction. The system and method provides a technical solution to exchange transactions directly off-chain. Participants in the method agree to make deposits and alter their transaction in such a way that a refund and compensation scheme put in place automatically relies on the confirmations in the blockchain of the transactions exchanged among participants thus providing increased security as well as anonymity. The method scales for an arbitrary number (n>2) of participants.
