For example, in the case where the size of the preset data warehouse can be accommodated, the ledger data of the blockchain can be migrated to the preset data warehouse as much as possible. Wherein, the ledger data may include: ledger records data and structured data.
In some embodiments, optionally, comprising: sending a request transaction broadcast to the block link points based on the intelligent contract; and acquiring account book data of each blockchain node through a consensus mechanism.

For example, according to the intelligent contract, the segmentation depth is obtained, the minimum block is created from the depth to the minimum block height, for example, when the segmentation is performed for the first time, the minimum block is created to have the height of 1, and after the block chain head Merkle (Hn-H1) of the region is calculated, the on-chain data is exported to a preset data warehouse; if the cutting data is too large, the cutting data can be divided into a plurality of times to horizontally form a plurality of historical ledger data.
For example, when the division depth of a certain division is 100000, the cut is made downward by 1 at 99999, and it should be noted that this is only an example and not a limitation.
S13, determining structured data of the historical account book data, and transferring the structured data to a corresponding preset data warehouse.
In some embodiments, optionally, comprising: calculating a block chain head of the partition area; and exporting the structured data in the data on the chain of the partitioned area to a preset data warehouse according to the block chain head.
For example, structured data, such as a link header, hash value, etc., may be exported to a preset data warehouse, thereby saving storage space for the original ledger.
S14, checking the account based on the account book data and the checking data.
In some embodiments, optionally, comprising: extracting reconciliation data based on the reconciliation file location; and checking accounts according to the checking account data and the preset data warehouse of each node.
For example, reconciliation data is extracted at the agreed reconciliation file location, and reconciliation information is calculated.
