[0027] In order to achieve the purpose of the present application, embodiments of the present application provide a block data verification method and device, which select a data node for storing new data from a block containing multiple data nodes; for the data node , Determine the check value of the newly added data, and calculate the updated check value of the data node according to the check value of the newly added data; according to the updated check value of the data node and the block The original check value of other data nodes included in the block is used to obtain the check value of the block; wherein the check value of the block is used to check whether the data stored in the block is consistent with the block chain The data stored in other blocks are the same. Compared with the prior art for processing all historical data, the embodiment of the application focuses on the newly added data of the block. For the newly added data block, it is proposed to use the incre...
