Abstract

The embodiment of the invention discloses a block chain-based trusted data exchange method and device, terminal equipment and medium. A specific embodiment of the method comprises the following steps: receiving a storage record table sent by a first terminal; sending the storage record table to a second terminal; receiving an access request sent by a second terminal; sending the access request to the first terminal; receiving ciphertext data and a public key set sent back by the first terminal; sending the ciphertext data and the public key set to a second terminal; deleting the ciphertext data; and updating the block chain. According to the embodiment, the first terminal publishes the storage record table to the block chain, and the storage capacity requirement of the block chain is met. And the first terminal encrypts the target data and then sends the encrypted target data to the uplink. And the block chain sends the encrypted data and the public key set to the second terminal and then destroys the ciphertext data on the chain, and the second terminal generates target encrypted data according to the encrypted data and the public key set. Only the first terminal has the target data in the data exchange process, so that the credible data exchange level is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the blockchain field, and specifically relate to a trusted data exchange method, device, terminal device, and computer-readable medium. Background technique [0002] Blockchain technology is an emerging technology emerging in the field of information technology and is the basis for building a value Internet. It is an information technology integrated with multiple technologies including distributed data storage, peer-to-peer network, and encryption technology. It has the characteristics of decentralization, openness, and autonomy. Its nature of decentralized trust provides a viable solution for us to achieve a fair exchange of data. At the same time, its distributed storage and the characteristics of data not easy to tamper are also very suitable for the safe sharing of design data. [0003] However, when data exchange and sharing is based on the blockchain, there are often the following technical p...
