Embodiment Construction
[0031] The technical solution of the present invention provides a smart contract virtual machine interface, such as Figure 1 to Figure 3 Shown, its technical scheme is as follows:
[0032] A block chain-based certificate deposit transaction encryption system, including an application layer, a middleware layer, and an underlying block chain system;
[0033] The application layer is the client that initiates the deposit transaction. The client generates certificate information according to its own needs on the client side. The application layer interacts with the middleware layer and transmits the certificate information to the middleware layer;
[0034] The middleware layer is used to provide an api interface for data interaction with the application layer and the bottom layer. The api interface is used to receive the deposit information and encrypt the deposit information to generate a transaction request. The encryption process is as follows: the api interface passes The sm...

The invention discloses a blockchain-based evidence storage transaction encryption system and method, and relates to the field of blockchain. An application layer is a client initiating an evidence storage transaction and generates evidence storage information, and the application layer transmits the evidence storage information to a middleware layer; an api interface of the middleware layer is used for receiving the evidence storage information and encrypting the evidence storage information to generate a transaction request, and the api interface transmits the transaction request to a bottom blockchain system; the bottom layer blockchain system node receives a transaction request, analyzes the transaction request, encrypts the transaction request to generate a transaction hash value, stores transaction data in a database after reaching a consensus through a decentration system, and returns the transaction data to the application layer to store a transaction result after successful storage. Through the encryption algorithm, the underlying blockchain system is more efficient in data exchange, and the performance and security of the encryption system are integrally improved.
Description
technical field [0001] The present invention relates to the field of blockchain data storage, in particular to a blockchain-based certificate deposit transaction encryption system and method. Background technique [0002] Existing distributed systems use international encryption algorithms to achieve data security in terms of data and communication encryption. For example, the public key encryption technology RSA is used as the encrypted communication protocol when the client and the server transmit confidential materials; MD5, SHA and other digest algorithms are used to verify the integrity of encrypted data; there are other symmetric encryption algorithms such as AES, DES and so on. However, with the development of computer computing power, related encryption algorithms such as MD5 and SHA are vulnerable to collision attacks, which gradually cannot meet the requirements of my country's data security and confidentiality in the digital economy. The invention provides an en...
