Classification: CPC G  H | IPC G

Claim 7:
8. The apparatus of claim 7, wherein the data structure of the local database based on the structured DAG acquired by the acquiring unit includes at least a milestone chain formed by a plurality of milestone blocks connected together and a peer chain formed by connecting the blocks created by each peer itself, and
wherein each of the blocks in the peer chain points to at least one of the milestone blocks,
wherein the creation unit comprises:
a building unit, stored in the memory and executed by the processor, configured to perform the forming the new block information; and
an adjusting unit, stored in the memory and executed by the processor, configured to perform the adjusting the nonce;

wherein the building unit uses the following information to form the new block information:
a pointer of a newly created milestone block in the longest milestone chain of the structured DAG to which the new block points; and
a pointer of a newly created block in the peer chain in the structured DAG to which the new block points,

wherein the building unit further uses the following information to construct new block information: the new block points to a most recent block created by another peer in the structured DAG, and
wherein the apparatus further comprises:
a confirming unit, stored in the memory and executed by the processor, configured to perform confirming that the new block is a milestone block when adjusting the nonce included in the new block information and determining that a hash result of the new block information satisfies a second difficulty condition,
wherein the information included in the distributed ledger of each node device is carried by the milestone block and a block directly or indirectly connected to the milestone block.
