Abstract: Provided is a method of linking multiple KV blocks in a KV chain to ensure data consistency, the method including allocating an internal key to both a first KV block and a recovery begin internal key, allocating a next internal key that is different from the internal key and that corresponds to a next KV block, and encapsulating respective user key values in the first KV block and in the next KV block, wherein the first KV block is accessed by reading the recovery begin internal key, and wherein the next KV block is accessed by reading the next internal key of the first KV block.
