1. A method, comprising:
receiving, by a first mining device associated with a first blockchain, a communication from a transaction device and directed to a first blockchain address associated with the first blockchain, wherein the communication comprises digital transaction information associated with a digital transaction, wherein the digital transaction information comprises a first portion and a second portion, and wherein the second portion of the digital transaction information is encrypted;
executing, by the first mining device, a smart contract associated with the first blockchain address, wherein the executing the smart contract causes the first mining device to store a first record comprising the first portion of the digital transaction information on the first blockchain and to determine one or more second mining devices associated with a second blockchain for processing the second portion of the digital transaction information, wherein the second blockchain is different from the first blockchain, and wherein the first mining device is not included in the one or more second mining devices; and
communicating, by the first mining device, the second portion of the digital transaction information to the one or more second mining devices to cause the one or more second mining devices associated with the second blockchain to (i) decrypt the second portion of the digital transaction information, (ii) store the decrypted second portion of the digital transaction information in a second record of the second blockchain, and (iii) link the second record in the second blockchain to the first record in the first blockchain.
