Abstract

A system includes a first processor configured to transmit to a second processor via a secure network session, a first payload configured for a transaction in a public blockchain network including a transaction amount, and a wallet address of a cryptocurrency account, and, in response to receiving, from a blockchain node associated with the cryptocurrency account, an indication that the cryptocurrency account has received a first monetary amount via the public blockchain network, transmit, to the second processor via the secure network session, a second payload indicating the first monetary amount that is less than the transaction amount. In response to the second processor validating the first monetary amount, the second processor transmits, using a blockchain node associated with the cryptocurrency account, a remainder of the transaction amount to the cryptocurrency account via the public blockchain network.

First claim

What is claimed is:

1. A system comprising:
a first computing device comprising a first processor; and
a second computing device comprising a second processor,
wherein the first processor is configured to:
establish a secure network banking session (SNBS) with the second processor, wherein the SNBS is active for an amount of time for a cryptocurrency transaction of a monetary amount of cryptocurrency;
decrypt an encrypted first payload to access the first payload;
in response to decrypting the encrypted first payload, transmit, via a public blockchain network (PBN) to a cryptocurrency account associated with the second processor, a first amount of cryptocurrency, wherein the first amount of cryptocurrency is less than the monetary amount of cryptocurrency;
decrypt the encrypted second payload to access the second payload;
in response to decrypting the encrypted second payload,
validate the first amount of cryptocurrency within the second payload to generate a first validation result;
encrypt the first validation result to generate an encrypted first validation result;
transmit, via the SNBS to the second processor, the encrypted first validation result; and
transmit, via the PBN to the cryptocurrency account, a second amount of cryptocurrency, wherein the second amount of cryptocurrency represents a remainder of the monetary amount of cryptocurrency; and

wherein the second processor is configured to:
establish the SNBS with the first processor;
generate a first payload comprising the monetary amount of cryptocurrency, a wallet address of the cryptocurrency account associated with the second processor, and a first transaction identifier corresponding to the cryptocurrency transaction;
encrypt the first payload to generate an encrypted first payload;
transmit, via the SNBS to the first processor, the encrypted first payload;
receive, via the PBN from at least one blockchain node associated with the cryptocurrency account, a first indication that the cryptocurrency account associated with the second processor has received the first amount of cryptocurrency;
in response to receiving the first indication, generate a second payload comprising the first amount of cryptocurrency, and a second transaction identifier associated with the first amount of cryptocurrency;
encrypt the second payload to generate an encrypted second payload;
transmit, via the SNBS to the first processor, the encrypted second payload; and
receive, via the PBN from at least one blockchain node associated with the cryptocurrency account, a second indication that the cryptocurrency account associated with the second processor has received the second amount of cryptocurrency.

2. The system of claim 1 ,
wherein the second processor is further configured to:
generate a third payload comprising a third amount of cryptocurrency for a second cryptocurrency transaction, and a third transaction identifier associated with the third amount of cryptocurrency;
encrypt the third payload to generate an encrypted third payload;
transmit, via the SNBS to the first processor, the encrypted third payload; and

wherein the first processor is further configured to:
decrypt the encrypted third payload to access the third payload.

3. The system of claim 2 , wherein the first processor is further configured to:
in response to decrypting the encrypted third payload, validate the third amount of cryptocurrency within the third payload to generate a second validation result;
encrypt the second validation result to generate an encrypted second validation result; and
transmit, via the SNBS to the second processor, the encrypted second validation result.

4. The system of claim 1 , wherein the first payload comprises a plurality of transaction amounts of cryptocurrency corresponding to a plurality of cryptocurrency transactions associated with the second processor, a plurality of first transaction identifiers, and a plurality of wallet addresses of one or more cryptocurrency accounts.

5. The system of claim 1 , whereby the second processor is configured to verify an integrity of the first payload or the second payload using metadata associated with each respective payload.

6. The system of claim 1 , wherein at least one of the first transaction identifier or the second transaction identifier is unique to the second processor.

7. The system of claim 1 , wherein at least one of the first transaction identifier or the second transaction identifier is unique to the cryptocurrency transaction.

8. A method comprising:
establishing a secure network banking session (SNBS) between a first processor of a first computing device and a second processor of a second computing device, wherein the SNBS is active for an amount of time for a cryptocurrency transaction of a monetary amount of cryptocurrency;
generating, by the second processor, a first payload comprising the monetary amount of cryptocurrency, a wallet address of a cryptocurrency account associated with the second processor, and a first transaction identifier corresponding to the cryptocurrency transaction;
encrypting, by the second processor, the first payload to generate an encrypted first payload;
transmitting, by the second processor via the SNBS to the first processor, the encrypted first payload;
decrypting, by the first processor, the encrypted first payload to access the first payload;
in response to decrypting the encrypted first payload, transmitting, by the first processor via a public blockchain network (PBN) to the cryptocurrency account associated with the second processor, a first amount of cryptocurrency, wherein the first amount of cryptocurrency is less than the monetary amount of cryptocurrency;
receiving, by the second processor via the PBN from at least one blockchain node associated with the cryptocurrency account, a first indication that the cryptocurrency account associated with the second processor has received the first amount of cryptocurrency;
in response to receiving the first indication, generating, by the second processor, a second payload comprising the first amount of cryptocurrency, and a second transaction identifier associated with the first amount of cryptocurrency;
encrypting, by the second processor, the second payload to generate an encrypted second payload;
transmitting, by the second processor via the SNBS to the first processor, the encrypted second payload;
decrypting, by the first processor, the encrypted second payload to access the second payload;
in response to decrypting the encrypted second payload,
validating, by the first processor, the first amount of cryptocurrency within the second payload to generate a first validation result;
encrypting, by the first processor, the first validation result to generate an encrypted first validation result;
transmitting, by the first processor via the SNBS to the second processor, the encrypted first validation result;
transmitting, by the first processor via the PBN to the cryptocurrency account, a second amount of cryptocurrency, wherein the second amount of cryptocurrency represents a remainder of the monetary amount of cryptocurrency; and

receiving, by the second processor via the PBN from at least one blockchain node associated with the cryptocurrency account, a second indication that the cryptocurrency account associated with the second processor has received the second amount of cryptocurrency.

9. The method of claim 8 , further comprising:
generating, by the second processor, a third payload comprising a third amount of cryptocurrency for a second cryptocurrency transaction, and a third transaction identifier associated with the third amount of cryptocurrency;
encrypting, by the second proce
