Detailed Description
As shown in fig. 1, in the embodiment of the present invention, a method for generating a block based on right issue includes the following steps:
s1, configuring the initial authority of the founding block server; and configuring a block network protocol;
by arranging the created block server, the candidate blocks generated early need to be authenticated by the created block server, so that the safety of verification of the blocks generated early in the block chain is higher. The allocated block network protocol is a condition required to be met by creating a block server, a node corresponding to the block and a requested node for communication. The invention is not limited to the specific form of the block network protocol.
S2, when receiving the block generation request of the node for the first time, judging whether the block generation request of the node conforms to the block network protocol, and if so, generating a candidate block according to the block generation rule; and jumps to step S3;
the block generation rule in this embodiment is not limited, and for example, a specific mathematical problem may be solved by calculation.
S3, authenticating the candidate blocks according to the authority through the created block server, and jumping to the step S4 after the authentication is passed;
this step is a significant difference between the present embodiment and the prior art, and in the prior art, the corresponding block can be generated as long as the block is suitable for meeting the preset condition. However, in the present embodiment, the generated candidate block is authenticated by the created block server. The authentication is not limited in this embodiment.
S4, the creating block server sends authentication information to the request node; the request node calculates the candidate block according to the authentication information to obtain a block, and jumps to step S5;
optionally, the requesting node calculates the candidate block according to the authentication information to obtain the block, where the authentication information includes a random number sent by the created block server, and performs SHA512 calculation on the candidate block by analyzing the random number in the authentication information.
And S5, adjusting the authority of the created block server according to the authority distribution rule, and distributing the authority to the corresponding nodes of the block.
In step S5, the authority of the created block server is adjusted, specifically, the weight value of the authority of the created block server is reduced, the authority is assigned to the node corresponding to the generated block, and the assigned object is assigned with the weight value of the authority. And the sum of the adjusted weight value of the permission of the created block server and the weight value of the distributed object to the permission is the weight value of the initial permission of the created block server.
Alternatively, the weight value of the authority of the created tile server is decremented, and the magnitude of the decrement of the weight value may be set according to the total amount of the number of generated tiles.
The purpose of this step is to gradually reduce the authority percentage of the created block server and gradually issue the authority of the created block server to the generated blocks.
By the embodiment, the blocks generated early are authenticated by the created block server, and the verification security in the block chain is higher.
In this embodiment, the created block server may be a general server, which aims to authenticate the candidate block according to the authority and send authentication information to the requesting node.
In the block generating method based on authority issue of the present invention,

s6, when the block generation request of the node is received again, judging whether the block generation request of the node conforms to the block network protocol, and if so, generating a candidate block according to the block generation rule; and jumps to step S7;
s7, the node requesting again sends the candidate block information to the block network through the block network protocol to obtain the authentication information of the created block server and the corresponding nodes of all blocks in the block network; skipping to step S8 when the received authentication information meets the preset authentication condition;
the preset authentication condition may be that a block server is created in the block network that sends the authentication information, and the sum of weighted values of the permissions corresponding to the nodes corresponding to all blocks is greater than or equal to a preset weighted threshold.
S8, judging whether the created block server after the authority adjustment accords with an exit mechanism; jumping to step S10 if the exit mechanism is satisfied; otherwise, adjusting the authority of the creating block server according to the authority distribution rule, and jumping to the step S9;
by setting the exit mechanism, the created block server can exit authentication when the generated blocks reach a certain number, so that the decentralized of the block chain and the safety guarantee when the number of the early blocks is too small are balanced.
Optionally, the exit mechanism is that a weighted value of the weight of the created block server after the permission adjustment is smaller than a preset threshold.
S9, the creating block server sends authentication information to the request node; the request node calculates the candidate block according to the authentication information to obtain a block, and performs authority distribution on the node corresponding to the block generated this time, and the process is finished;
and S10, the request node calculates the candidate block according to the default authentication information to obtain a block, and allocates the authority to the node corresponding to the block generated this time, and the operation is finished.

the first level network address segment A, B, C and limits A, B, C the upper limit on the number of tiles in the corresponding tile pool.
Further, in the second-level network address segment, a is divided into a1, a2 and a3, and the upper limit of the number of blocks in the corresponding block pool of a1, a2 and a3 is limited, and the blocks can be subdivided successively.
Through the preferred embodiment of the invention, the requirement of the block pool in the network address field of the hierarchy is required to be met, and the requirement of the block pool corresponding to the network address field of the hierarchy above the network address field of the hierarchy is also required to be met, so that the block has more hierarchy for the limitation of the number when being generated.
