It is intended to, as shown in Figure 1, the method for mitigating node storage load in the block catenary system includes the following steps：
S101, after the node with block production permission any in block catenary system obtains task requests and executes, judgement is worked as
It is preceding whether to meet block working condition.
That is, after the node with block production permission any in block catenary system gets task requests,
Task requests are parsed and are executed, after executing to task requests, whether judgement currently meets block formation condition.
Wherein, block production permission refers to after meeting block working condition, after upper block timeline
Task is packaged as the permission of new block, it should be noted that and block produces there are many determination modes of permission, such as：Pos equity
Mode of proof, pow proof of work mode and dpos share authorisation verification mode；Therefore, herein not to block production permission
Method of determination is limited.

Part；Alternatively, presetting the task amount threshold of each block, have the node of block production permission after executing task requests,
Judge whether the task quantity in a upper block after timeline reaches task amount threshold, and determines when the judgment result is yes
Currently meet block working condition.
S102, if meeting block working condition, this is broadcasted if having the node of block production permission to block chain network
The memory node address of the last block of inquiry.
That is, having the node of block production permission when judgement currently meets block working condition, then to block
Chain network broadcasts the memory node address of the last block of inquiry, to obtain the address set of the memory node of last block, after being convenient for
It is continuous that the address set of the memory node of last block is written to new block, so that any node is after obtaining new block, it can
The downloading of last block is carried out according to the address set of the memory node of the last block stored in block, and then in a recursive manner
Obtain entire block chained file.
S103, Self address and block Hash information are sent to this by the memory node of last block has block manufacturing right
The node of limit.
That is, memory node of the node with block production permission to the block chain network broadcast last block of inquiry
Address, after the memory node of last block receives the inquiry, Self address and block Hash information, which are sent to this, to be had
The node of block production permission.
S104, there is the node of block production permission to compile the memory node address of last block into address list for this, and
New district is packaged into together with the mission bit stream and timestamp after the block Hash information of last block, last block timeline
Block, and set of random numbers is generated according to the node total number in block chain network, and set of random numbers and new block are packaged as
Web broadcast packet to block chain network to be broadcasted, wherein the number of the random number in set of random numbers is less than or equal to node
Sum.
In other words, the Self address that the node with block production permission is sent in the memory node for receiving each last block

Web broadcast packet in block chain network to broadcast, wherein it is total that the number of the random number in set of random numbers is less than or equal to node
Number.
Wherein, there are many acquisition modes of node total number, for example, when block chain network is added in new node, by new node
The address addition such as node address table in block catenary system, and the node in block catenary system is controlled every preset time to block
Chain network sends heartbeat packet, with the current node address table of more new block chain network.
As an example, each node timing in block chain network sends network inquiry packet to block chain network, with
In inquiry block chain network there is currently node, and obtain return response after update current node address table and node it is total
Number.That is, the timing of each node to block chain network send network inquiry packet in inquiry block chain network there is currently
Node, other nodes return to confirmation message and own node address, when receiving the network inquiry packet to send net
The node of network inquiry packet updates current node address table according to the confirmation message received and own node address and node is total
Number.
Wherein, there are many generating algorithms of random number, for example, Monte carlo algorithm, Las Vegas algorithm, Sherwood are calculated
Method etc.；The generating algorithm of random number is not limited herein.
Wherein, there are many set-up modes of the generation number of random number, such as：Directly according to the node in block chain network
Sum, generating number is the random number less than or equal to node total number.
As an example, it keeps not repeating between random number, to guarantee that each random number all points to different nodes；With
The number of machine number obtains according to the following formula：M=rounding（n/k）, wherein M be random number number, n be block chain network in when
Front nodal point sum, k is the default integer chosen according to the actual conditions of block chain network, wherein there are many selection modes of k,
For example, according to the health value of node total number, each node in current block chain network（Hardware configuration information including each node,
The network rate of each node and each node tasks response time etc.）Carry out the selected of k value；Alternatively, according to current block link network
Task requests book carries out the selected of k value in node total number and preset period of time in network；Alternatively, according in current block chain network
Idle node number and block production frequency carry out the selected of k value；To prevent because of memory block by reasonably determining k value
The node of block is very few and causes block chain network unstable, the hair because the case where history block can not obtain caused by node exception
It is raw.
It should be noted that the quantity of memory node and k value are in inverse correlation relationship, that is to say, that k value is bigger, storage section
Point is fewer, and the node storage load in block catenary system is smaller, conversely, k value is smaller, memory node is bigger, in block catenary system
Node storage load it is bigger.
S105 parses Web broadcast packet after other nodes in block chain network receive Web broadcast packet
And the task in new block is executed, and prosthomere is worked as according to set of random numbers inquiry block chain network after the completion of task execution
Dot address table, to judge that whether representing node in random number is directed toward itself.

Row parses and executes task therein, and after the completion of task execution, inquires working as block chain network according to set of random numbers
Front nodal point address table judges that node whether is represented in random number is directed toward itself, in other words, judges block link network where own node
The position of the current node address table of network whether be random number be directed toward position, with judge own node whether need to new block into
Row storage.
As an example, when generating the current node address table of block chain network, according to each in node address table
Node address is numbered, when other nodes in block chain network receive Web broadcast packet and to broadcast packet carry out parsing and
After executing task therein, judge the set of random numbers in Web broadcast packet whether include block chain network present node
The number of own node address in the table of location, and when the judgment result is yes, judge that node is represented in random number is directed toward itself.
S106, if so, then the node stores new block.
As an example, when the node judges that representing node in random number is directed toward itself, new block is deposited
Storage；When the node judges that not representing node in random number is directed toward itself, then the node abandons new block, not to new block
It is stored.
