The problem of protecting blockchain system nodes from threats of user deanonymization, access restrictions, and the imposition of false information about the state of the blockchain is considered. A method for anonymizing traffic between blockchain system nodes based on garlic routing is developed, supporting integration with a consensus mechanism. Experimental studies demonstrate that the proposed method can improve the security of blockchain systems used in large-scale network infrastructures.
