Abstract: The present disclosure relates to methods and systems for transferring data in a blockchain network. Specifically, the present disclosure relates to computer-implemented methods for creating and encrypting electronic wallets in blockchain networks and systems and methods configured to carry out data transactions in the blockchain network. For example, the present disclosure describes a method for creating and encrypting an electronic wallet of a blockchain network, comprising a step of obtaining the electronic wallet by a computing device from a user. The electronic wallet may include a private password data, a public password data, and a wallet identification data. The method has steps wherein the private password data, the public password data and/or the wallet identification data are encrypted with random salt data. The encrypted data is transmitted via an API to computing modules having functions of data storage, processing of requests, and blockchain network access.
