Abstract

The invention discloses a blockchain-based digital asset processing method and device. The method comprises the following steps: receiving private ciphertext for a digital asset circulated from a sending end to a receiving end through a blockchain, and a preset public key; and obtaining a sharing public key for sharing the private ciphertext based on the preset public key, so that when the private ciphertext and the sharing public key are broadcast in the blockchain, blockchain nodes on the blockchain can share the private ciphertext based on the sharing public key and reach a blind consensus on the shared private ciphertext, and after the consensus on the private ciphertext is reached, the private ciphertext can be decrypted by at least one of three parties, i.e., the sending end, the receiving end and a monitoring end, based on a preset private key to obtain plaintext of the digital asset. The method and device provided by the embodiment of the invention has the advantages that the privacy right of a user is protected; under the premise of privacy protection, the single general digital asset can be smoothly circulated within one blockchain or among multiple blockchains, and a total currency amount remains unchanged; and a monitoring party other than the transaction parties can monitor transaction information at any time.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a block chain-based digital asset processing method and device. Background technique [0002] With the development of communication technology, blockchain is gradually being applied to data processing application scenarios due to its advantages of decentralization, openness, transparency, and immutability. Due to the limitation of its technology itself, it is difficult for the blockchain to carry massive data transactions. At the same time, different blockchains carry different types of data services, which also meet the actual business needs. For example, the equity blockchain, the real estate blockchain, and the micropayment blockchain carry corresponding digital asset services respectively. [0003] Different existing blockchains each use their own unique currency. The use of digital currencies on different blockchains for asset transactions requires the c...
