Реферат: Implementations of the present disclosure include receiving, from a first account, a digitally signed copy of a commitment value of a first amount of a transaction amount generated based on a first random number, the first amount of the balance transfer and the first random number encrypted using a public key of the first account, a second amount of the balance transfer and a second random number encrypted using a public key of the second account, and a set of values generated based on one or more selected random numbers. The first account determines if the first amount and the second amount are the same and if the first random number and the second random number are the same based on the set of values, and updates the balance of the first account and a balance of the second account based on the first amount of the balance transfer.
