Abstract: A block data archiving method carried out by a blockchain node is described. The method includes determining to-be-archived block data when detecting that a resource of a block stored in the first blockchain node meets a block data archiving condition. The method further includes sending an archiving request to one or more other blockchain nodes; negotiating a consensus with the blockchain node in the same group based on received consensus response information fed back by the blockchain node in the same group one or more other blockchain nodes; and sending the to-be-archived block data to a third-party storage server for archiving in accordance with determining that a consensus is reached and a consensus result that the first blockchain node is a consensus blockchain node is obtained. The consensus result is used to determine the first blockchain node or any blockchain node in the same group is a consensus blockchain node.

Abstract: This application relates to a data processing method, a blockchain node, and a blockchain system. The method includes: acquiring a read set of a first transaction, and acquiring a first block height, where the first block height is a maximum block height in the blockchain system when the first transaction is endorsed, and a cache of the first node stores write sets included in a plurality of flushed blocks in the blockchain system and block heights corresponding to the plurality of flushed blocks; and when the first block height falls within a range of the block heights corresponding to the plurality of flushed blocks, obtaining validity of the first transaction based on the read set of the first transaction and the write sets included in the plurality of flushed blocks.
