A system may be disclosed in the present disclosure, comprising: an interface service unit configured to perform at least one of sending data to or receiving data from one or more users via a user interface; and a transmission unit including: a blockchain adaptor configured to transmit data to a plurality of different types of blockchains, via a blockchain interface, according to data format and communication mode requirements of each of the plurality of different types of blockchains and a transmission controller configured to trigger a smart contract running on a blockchain of the plurality different types of blockchains via the blockchain interface, and control a data transmission under instructions from the smart contract, wherein the data transmission is based on data received from the user interface.

Data service system

A data transmission platform for data transmission using a blockchain is configured to receives ciphertext data from a data provider, wherein the ciphertext data include transmitted data authenticated by the data transmission platform and encrypted by the data provider; identifies a target data requestor; creates a smart contract according to a data transmission requirement of the target data requestor; uploads the smart contract to a blockchain; sends a data transmission request to the data provider; re-encrypts the ciphertext data to obtain re-encrypted data using a re-encryption key generated by the data provider; triggers the smart contract to send the data transmission demand of the data requestor to the data provider; and notifies the data requester to extract the decrypted data and perform decryption to obtain the transmitted data.

Data transmission method, system and platform using blockchain, and storage medium

A data processing method, apparatus, medium and terminal thereof are disclosed in the present disclosure, the method comprising: determining data-to-be-processed based on data provided by a data provider, the data-to-be-processed includes plaintext description data; storing the plaintext description data to a database, the database may be used to support a search engine; and in response to confirmation of search results from the search engine by a data requestor, triggering a smart contract running on blockchain, the smart contract includes communication and records between the data requestor and the data provider. The technical solution in some embodiments improves search efficiency of data in blockchain technology applications.
