Block chain data interaction method and device, equipment and storage medium

The invention is suitable for the technical field of block chains, and provides a block chain data interaction method and device, equipment and a storage medium, and the method comprises the steps: compressing to-be-interacted data, and obtaining compressed data; and inputting the compressed data into a smart contract of the block chain, and processing the to-be-interacted data after the smart contract decompresses the compressed data to obtain an interaction result of the to-be-interacted data. The block chain data interaction method, device and equipment and the storage medium provided by the invention are used for solving the problem of how to reduce the data volume of to-be-interacted data in a block chain and the network load and computing resources in the interaction process. 本申请适用于区块链技术领域，提供了一种区块链数据交互方法、装置、设备和存储介质，包括：对待交互数据进行压缩，得到压缩数据。将压缩数据输入至区块链的智能合约，其中智能合约解压压缩数据后处理待交互数据，得到待交互数据的交互结果。本申请提供的一种区块链数据交互方法、装置、设备和存储介质用于解决如何降低区块链中待交互数据的数据量，以及交互过程中的网络负载和计算资源。
