Problems solved by technology

However, in the alliance chain environment, there are often some private data among many institutions, which is contrary to the concept of complete transparency of data on the blockchain
In order to realize private data sharing between certain institutions, the existing solution is often to build a new alliance chain for this alone. As the number of institutions grows, the number of alliance chains generated will also increase accordingly. Exponential growth, greatly increasing the complexity of deployment and operation and maintenance

Embodiment Construction

[0016] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Such as figure 1 As shown, a method for protecting privacy transactions based on the alliance block chain is characterized in that the alliance block chain platform includes a predefined API interface dedicated to privacy transactions, and the specific API interface that needs to be protected is specified in the API interface. private data and a list of parties involved in the private transaction. The API design of the alliance blockchain platform is the premise of privacy protection, providing...

Abstract

The invention discloses a privacy transaction protection method based on coalition block chain, the method defines a set of API interface for privacy transaction in the block chain platform, a user ofthe block chain platform initiates a privacy transaction to a transit node by calling the API interface, once the relay node is responsible for synchronizing the privacy transaction to all designatedparticipant nodes, the transit node reconstructs a public transaction, only the hash value of the privacy data and the participant information are stored in the public transaction, and then the public transaction is recorded into the public account books of all the block chain nodes through the normal block chain uplink flow, and finally, the participants of the privacy transaction record the corresponding privacy transaction into their own privacy account books. The privacy transaction protection method of the invention makes up the vacancy of the privacy requirement in the current block chain system, and improves the use value of the coalition block chain.

Description

technical field [0001] The present invention relates to the application of blockchain technology, in particular to a method for protecting privacy transactions based on alliance blockchain. Background technique [0002] Blockchain technology is essentially a decentralized distributed ledger database. The nodes in the blockchain collectively maintain a reliable and consistent copy of the database in a decentralized manner. In layman's terms, blockchain technology refers to a way for all people to participate in bookkeeping. The transaction confirmation on the blockchain is completed by all nodes on the blockchain, and the consensus algorithm ensures its consistency. All nodes maintain a public The public ledger is visible to any node on the blockchain, thus ensuring that it cannot be forged and tampered with. [0003] According to the degree of openness, blockchains can be divided into public blockchains (public chains), alliance blockchains (alliance chains), and private b...
