A blockchain transaction record that is selected from a blockchain account book associated with a blockchain and satisfies a specified condition is obtained by a blockchain member. The blockchain transaction record is compared with an off-chain transaction record maintained by the blockchain member to obtain a comparison value indicating whether the off-chain transaction record is consistent with the blockchain transaction record. If the comparison value indicates that the off-chain transaction record is inconsistent with the blockchain transaction record, the off-chain transaction record is modified based on the blockchain transaction record to make the off-chain transaction record consistent with the blockchain transaction record.

An asset transfer request to transfer an asset to a blockchain member associated with a blockchain is detected, where the asset is of a specified asset type and is issued by a specified anchor in the blockchain. Whether there is a maximum trusted asset limit configured by the blockchain member for the specified anchor and that corresponds to the specified asset type is determined. If it is determined that the maximum trusted asset limit is not configured, application of the asset transfer request to the asset is prohibited. However, if it is determined that the maximum trusted asset limit is configured, whether the maximum trusted asset limit is exceeded is determined. If it is determined that the maximum trusted asset limit is not exceeded, the asset transfer request is applied to the asset.

A blockchain asset that is transferred from a second blockchain member is received at a first blockchain member in response to an asset transfer request for transferring an asset between a payer and a payee, where the first blockchain member and the second blockchain member associated with a blockchain. In response to receiving the blockchain asset, an off-chain asset transfer-out operation for the payee is performed by the first blockchain member. If the off-chain asset transfer-out operation fails, a transaction reversal application for an asset transfer transaction corresponding to the asset transfer request is written into the blockchain by the first blockchain member. In response to writing the transaction reversal application, an asset clearing with the second blockchain member for an off-chain asset corresponding to the off-chain asset transfer-out operation is performed by the first blockchain member.

Input information associated with a data field is received. The data field is included in a page. A determination is made as to whether the input information includes an error. In response to determining that the input information includes an error an anchor is determined in the page corresponding to a location of the data field in the page. An error popup is displayed on the page. The error popup includes an error list that includes an error notification associated with the error. The error notification includes the location of the data field in the page.
