Referring to Fig. 2, Fig. 2 is that the embodiment of the present invention provides a kind of configuration diagram of block catenary system.As shown in Fig. 2,
Block catenary system 200 includes ordinary node 21, agent node 22 and miner's node 23.
Ordinary node 21, agent node 22 and miner's node 23 all as the block chain node in block catenary system 200,
It all supports point-to- point communication mode (Point to point communication, P2P), passes through the mutual service area of P2P mode
Block chain data.Wherein, ordinary node 21 and agent node 22 communicate, and agent node 22 and miner's node 23 communicate.
In the present embodiment, the quantity of ordinary node 21, agent node 22 and miner's node 23 can be multiple, and be distributed
In each geographic area.
Ordinary node 21 holds the electronic money of circulation, and the right of vote by ballot is possessed in block catenary system.Common section
Point 21 can carry out relationship trading operation, but the not packing book keeping operation power of block, can only be from the correlation for possessing packing book keeping operation power
Synchronous recording block data at node.
Ordinary node 21 is encoded with intelligent contract code, and user can need in voluntarily editorial intelligence contract according to business
Hold, for example, intelligent treaty content includes the business tine occurred for predicted events, for issuing the best real-time routes in two places
Business tine, business tine for inquiring the best real-time routes in two places etc..
User's operation ordinary node 21 triggers intelligent contract, so that ordinary node 21 executes intelligent contract, to obtain correspondence
The implementing result of business function.For example, user's operation ordinary node 21, executes the intelligent contract occurred for predicted events, makes
It obtains ordinary node 21 and obtains prediction result, and prediction result is broadcasted into the whole network.For another example user's operation ordinary node 21, executes
For issuing the intelligent contract of the best real-time routes in two places, so that ordinary node 21 broadcasts best real-time routes to the whole network.
In some embodiments, block catenary system has multiple business function, wherein each block chain node is also assigned
And it is responsible for one or more business functions, each block chain node completes respective business function to realize answering for block catenary system
With.When block chain nodes multiple in block catenary system are responsible for same line of business function, on the one hand, due to being responsible for same line of business function
Block chain node it is more various, cause the waste of resource.On the other hand, due to the participation energy of user's operation block chain node
Power, experience are all different, when each block chain node is owned by same line of business function, can not embody the otherness of participant,
Professional ability can not be played, the application effect of entire group is difficult to reach higher level.
For example, prediction field, with stock analysis experience deal maker to the view of shares changing tendency have it is higher can
Reliability, it is relatively high, common stock invester's operation ordinary node that deal maker, which operates ordinary node 21 and provides the confidence level of prediction result,
21 confidence levels for providing prediction result are relatively low, furthermore, the confidence level of the participant of long-term forecast mistake, opinion should be non-
It is often low.The user A operation publication best real-time routes in two places of ordinary node 21 are more accurate, and user B operates ordinary node 21 and issues
The deviation of the best real-time routes in two places is bigger.Therefore, user's operation ordinary node 21 executes the execution knot that intelligent contract obtains
Fruit can vary with each individual, and the professional ability of user is different, and implementing result is also different,
For this purpose, in the conventional technology, in order to realize different business functions in different blocks chain node, by not
Different rights are set with block chain link point, to ensure that every business function can be executed securely, such mode belongs to center
The usual way of change system, needs the business function of pre-defined different blocks chain node, and provides which user can pacify
Dress realizes the block chain node of specific transactions function.Obviously, traditional approach will lead to there are some franchise nodes, this and block chain
The original intention of decentralization is disagreed.Therefore, one embodiment is provided at least hereafter to solve defect existing for traditional technology.
In the present embodiment, ordinary node 21 can prestore multiple types intelligence contract, can be general according to user's operation
The trigger request that logical node 21 is distributed, parses the execution type of intelligent contract.Ordinary node 21 is further according to the intelligence parsed
The execution type of contract executes corresponding intelligent contract, to generate original block data.
Original block data are packaged into block data to be verified by agent node 22.Then, agent node 22 will also be to
The block data of verifying is signed, and the block data after signature is transmitted to miner's node 23.Miner's node 23 utilizes
Block data after the public key verifications signature of agent node 22, if being proved to be successful, then it is assumed that the block data after the signature is to close
What method agent node 22 was sent, it is subsequent that common recognition processing then is carried out to the block data.If verifying is failed, then it is assumed that the signature
Block data afterwards is that illegal agent node is sent.For example, agent node 22 is using own private key to the Hash of current block
Content makees signature operation, obtains the signature.
Miner's node 23, which is used to know together, verifies the block data that agent node 22 uploads.Wherein, miner's node 23 can prop up
Hold it is following any one common recognition algorithm: proof of work (Proof of Work, PoW), equity prove (Proof of Stake,
POS), share authorisation verification (Delegate proof of Stake, DPoS), practical Byzantine failure tolerance (practical
Byzantine Fault Tolerance, PBFT), authorization Byzantine failure tolerance (Delegated Byzantine Fault
Tolerance, DBFT) etc..
Each miner's node 23 all needs to register in agent node 22, and after success to be registered, which is just legal
Miner's node.Registration process is as follows:
1, miner's node 23 submits registration information to agent node 22.
Wherein, which includes one or more of information: equipment Serial Number SN, Yong Huxin of miner's node 23
Breath and miner's wallet address.
2, agent node 22 checks registration information.
Checking process includes: that SN whether there is in database, whether SN has been bound other users etc..
3, agent node 22 records registration information.
4, registering result is returned to miner's node 23 by agent node 22.
5, agent node 22 broadcasts new log-on data to block catenary system 200.
In above-mentioned block catenary system 200, block is the carrier for store transaction summary info, and each block all includes
Block head and block body, the information that block head is recorded is for identifying block itself, the informative abstract of previous block and block
Position in entire account book.Block body is used to store transaction summary info and verifying Transaction Information and saves transaction not usurped
Change.
Block chain is to connect each block one by one according to the sequence for generating the time, just forms the number of a chain type
According to storage organization.In entire block chain, first block is known as creating generation block, and block height is 0, each block later
Block height successively add 1, and the cryptographic Hash of previous block head is written in block head.Each block on block chain it
Between linked by the upper block head cryptographic Hash on each block.Therefore, block chain have can not tamper.
It is understood that the execution of above-mentioned business function can be realized using intelligent contract mode, it also can be with non intelligent
Contract mode is realized.
Referring to Fig. 3, Fig. 3 is that the embodiment of the present invention provides a kind of flow diagram of block chain node evolution method.Such as
Shown in Fig. 3, block chain node evolution method S300 includes:
S31, target block chain node obtain the confirmation of business function as a result, business function is held by target block chain node
Row；
In the present embodiment, block chain node includes target block chain node and non-targeted block chain link point, for a certain
For business function, when block chain node executes a certain business function, which is target block chain node,
Its block chain node is non-targeted block chain link point.It is understood that " target " in " target block chain node " is to be used for
It distinguishes and executes the block chain node of a certain business function in specific time and do not execute the block chain node of a certain business function,
" target " or " non-targeted " is used to be not intended to restrict the invention explanation range and the guarantor of the block chain node of embodiment offer
Range is protected, only the supplementary explanation embodiment of the present invention.Therefore, in some use environments, " target block chain node " and " non-mesh
Mark block chain node " can be converted mutually, for example, block chain node Q1 is able to carry out business function F1 in time t1,
Block chain node Q2 has not been able to execute business function F1, is target block chain for business function F1, block chain node Q1 therefore
Node, block chain node Q2 are non-targeted block chain link point.
In the present embodiment, business function can be for any suitable type and the business that can be applied on block chain is patrolled
Volume, block chain link point executes business function according to service logic, and generates the implementing result of the business function, for example, business function
It can include forecast function, acquisition prediction result function, confirmation prediction result function, publication route function etc..
In order to safeguard the original intention of block chain decentralization, when initialization, several block chain nodes can carry out same item
Business function, after having executed business function, each block chain node all generates implementing result, and sends to other block chain nodes
Implementing result, so that other block chain nodes return to confirmation as a result, the confirmation result executes knot for evaluating according to implementing result
The accuracy or reliability or real-time etc. of fruit.For example, please referring to Fig. 4 a, each block chain node is all used as start node,
Execute identical business function F1, wherein block chain node 41 sends implementing result, block to block chain node 42,43 and 44
Chain node 42 is accurate compared with 43 think the implementing result, and then, block chain node 42 and 43 is within a preset period of time to block
Chain node 41 respectively sends confirmation as a result, block chain node 44 thinks that the implementing result is not accurate enough, then in preset time period
It is interior, confirmation result is not sent to block chain node 41.At this point, block chain node 41 receives altogether 2 within a preset period of time
Confirm result.
S32, target block chain node are according to confirmation as a result, evolution business function.
In the present embodiment, the multi-pass operation with user on block chain node, the industry that each block chain node is served as
Business functional role changes, subsequent when operating corresponding block chain node again, and the functional effect reached is also different, thus real
The evolution of the business function of existing block chain node.
The embodiment of the present invention is hereafter elaborated by taking forecasting system as an example.In the present embodiment, forecasting system is defined as:
For still nonevent thing, prediction result is provided with the substantive requirements of form user of enquirement, after thing generation, determines that user's is pre-
Whether accurate, then give different rewards for the user of different accuracy if surveying.
A and 4b referring to Figure 4 together, when the prediction of block chain node 41 in Fig. 4 a is repeatedly judged as success, then the ginseng
The confidence level of the forecast function of block chain node 41 corresponding with person is elevated, subsequent, which is just increasingly becoming
The prediction authoritative node 410 of forecast function.When the prediction of block chain node 42 is repeatedly judged as failure, then the participant is corresponding
The confidence level of forecast function of block chain node 42 be lowered, subsequent, block chain node 42 becomes prediction rubbish node 420,
The forecast function of subsequent block chain link point 42 is gradually eliminated again.After prediction, block chain node 43 can be repeatedly accurate
Ground judges that the prediction is correctly, then block chain node 43 is just as the judgement node 430 of high confidence level.After prediction simultaneously
When true result being waited to occur, if result is repeatedly judged and tallies with the actual situation for the fact that block chain 44 typing of node, block
Chain node 44 is just as the prophesy machine node 440 of high confidence level.After forecasting system is performed a number of times, each area in forecasting system
Block chain node will show different responsibilities, to be different from the prior art, be responsible for the mutually same trade when both realizing by initializing
Business function arrives the evolution for being responsible for specific transactions function specializedly again, in turn avoids the predefined function of centralization.
Therefore, in the present embodiment, since block chain can be being corresponded to according to user without pre-defined franchise node
Node execute business function as a result, the evolution business function, to gradually and neatly adjust the business function role of node,
So that the professional ability of node behind participant is farthest played, under the decentralization original intention for keeping block chain, so that
The application quality of entire block catenary system is promoted.
In order to enable the evolution of business function to visualize, in some embodiments, each business function all respective weights.
For example, please referring to table 1, table 1 is that Fig. 4 b provides the signal of the business function respective weights of each block chain node in forecasting system
Table.It is as shown in table 1:
Table 1
As shown in Table 1, weight is bigger, and the confidence level of business function is higher；Weight is smaller, and the confidence level of business function is got over
It is low.Therefore, in some embodiments, can by adjusting business function weight to realize evolution.Referring to Fig. 5, S32 packet
It includes:
S321, target block chain node are according to confirmation as a result, the weight of adjustment business function；
The weight of S322, target block chain node according to business function adjusted, evolution business function.
In the present embodiment, when confirming that result meets preset condition, block chain node can be improved or reduce business function
The weight of energy.When confirming that result does not meet preset condition, block chain node can reduce or improve the weight of business function.Its
In, preset condition is customized according to business demand by user, also, adjusts weight mode and also made by oneself by user according to business demand
Justice.
It, can will be after adjustment when target block chain node is according to the weight evolution business function of business function adjusted
Business function weight be packaged in next time execute business function implementing result.Since different weights correspond to target block chain
The different confidence levels of the business function of node, other participants can know the confidence level of the business function by weight.Example
Such as, in above-mentioned forecasting system, when predicting 410 predicted events of authoritative node, present weight " 10 " is encapsulated in current prediction thing
In the implementing result of part, other participants obtain the present weight " 10 " of prediction authoritative node 410 by parsing the implementing result,
Then compare the prediction result trusted and provided in prediction authoritative node 410.When other block chain link point prediction similar events,
Equally present weight " 2 " is encapsulated in the implementing result of current predicted events, other participants are by parsing the implementing result
The present weight " 2 " for obtaining the block chain node, compared to prediction authoritative node 410, other participants tend to trust prediction
The prediction result that authoritative node 410 provides, without trusting the prediction result provided in the block chain node.Certainly, when prediction is weighed
Prestige node 410 is done evil, and has not been able to provide prediction result for a long time or subsequent prediction result is repeatedly judged as mistake, Qi Tacan
It can change with person and trust direction.
It in some embodiments, can provisional this of update business when target block chain node executes business function
The present weight of function.For example, firstly, user's operation target block chain node executes business function F2, target block chain node
The present weight " 5 " of business function is temporarily updated according to default weight increment " 2 ", therefore, interim updated present weight is
"7".Table 2 is please referred to, table 2 provides a kind of schematic table of the present weight of provisional update business function for the embodiment of the present invention.
It is as shown in table 2:
Table 2
| Type of service | Default weight increment | State |
| Business function F1 | 0.1 | It is to be confirmed |
| Business function F2 | 2 | It is to be confirmed |
| Business function F3 | 3.5 | It is to be confirmed |
Secondly, target block chain node is by business function, temporarily updated present weight is packaged in execution business function
