Method for hiding transaction address in blockchain system, computer readable storage medium and blockchain system

Abstract

The invention relates to a method for hiding a transaction address in a blockchain system. The method comprises the steps that a transaction initiator generates a session key pair; the transaction initiator generates an encrypted initiator address and an encrypted receiver address based on the transaction private key, the receiver address and the initiator address in the session key pair, and writes the transaction public key, the encrypted initiator address and the encrypted receiver address in the session key pair into transaction information; and the transaction user calculates an own address according to an own private key and the transaction public key, and judges whether the output of the transaction points to the transaction user or not based on the own address, the encryption initiator address and the encryption receiver address. The invention also relates to a computer readable storage medium and a blockchain system. According to the method, the number of keys needing to be maintained can be reduced, so that the calculation amount is reduced, the encryption process of the blockchain is simplified, and the encryption cost is reduced.

Description

technical field [0001] The present invention relates to the field of block chains, and more specifically, relates to a method for hiding transaction addresses in a block chain system, a computer-readable storage medium and a block chain system. Background technique [0002] Blockchain is a distributed ledger technology that is jointly maintained by multiple parties, uses cryptography to ensure transmission and access security, and can achieve consistent data storage, difficulty in tampering, and prevention of repudiation. Traditional blockchains based on UTXO (UnspentTransactionOutput), such as Bitcoin, use a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors. Except that the private information of all parties to the transaction is encrypted, anyone can The balance of each transaction or an address can be queried through the public interface, and all transaction data is open and transparent. However, this op...

Problems solved by technology

However, the disadvantage of Monero is that it needs to maintain two pairs of public and private keys, the view key and the spend key, so the process is complicated and the amount of calculation is large, which increases the encryption process and cost of the blockchain system
