Abstract

The invention discloses a block chain data processing method, and the method is used for a processor. The method comprises the steps: generating first Hash value based on original data transmitted by a first client, receiving a first encryption Hash value generated by the first client based on first secret key encryption, and receiving a second encryption Hash value generated by a second client based on second secret key encryption, wherein the first client and the second client are different; and storing the second encryption Hash value. Through enabling the original data to be hashed to obtain the Hash value and enabling a beneficiary concerned to encrypt the Hash value through a secret key, the method guarantees that only a user who owns a public key matched with the secret key can look up the data stored in a block chain, and improves the safety of stored data in the block chain.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and more specifically, to a method and device for processing blockchain data. Background technique [0002] The blockchain is essentially a centralized database, like a shared ledger. As the underlying technology of Bitcoin, the blockchain has the characteristics of decentralization, openness, anonymity, and immutability. In the traditional public blockchain, data such as user account information and transaction content are public, and any user can participate in bookkeeping and view transaction data, and only protect user privacy through "pseudo-anonymity". Although this increases users' confidence in the authenticity and reliability of data, for the financial industry, the complete disclosure of data involves a lot of business secrets and interests, so it is necessary to use a privacy protection method to protect data privacy. [0003] In the prior art, banks solve this problem by e...
