It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
In order to provide a kind of unified Time Service mechanism to block chain, the embodiment of the invention provides in a kind of block chain
The determination method of time, as shown in Figure 1, which comprises
101, the intelligent contract receiving time acquisition request on block chain.
Intelligent contract refers to that is defined in digital form is capable of the contract of automatic implementation of the provisions.In block chain technical field,
Intelligent contract refers in particular to the computer program for triggering based on scheduled event, can not distorting, executing automatically.Intelligent contract once generates,
Any one node can often call the intelligence contract in block chain, to realize a certain business or transaction.The present invention is real
Applying the intelligent contract in example can be the contract of special offer Time Service, and being also possible to includes Time Service and other are serviced
Contract.But when the intelligence contract is the special contract for providing Time Service, the opposite efficiency of operation time includes other
The operation efficiency of the contract of service often wants high, therefore provides the contract of Time Service it is preferable to use special.
It, can be to providing the intelligent contract hair of Time Service when some node in block chain it needs to be determined that when current time
Time acquisition request is sent, after receiving the time acquisition request so as to the intelligence contract, can be worked as to what the node feeding back determined
The preceding time.
102, intelligent contract determines rule according to preset time, determines the current time of the block chain.
It is (i.e. default according to the processing logic of itself after intelligent contract receives the time acquisition request of requesting party's transmission
Time determines rule), it determines the current time of block chain, and after determining time result, time result is fed back to ask immediately
The side of asking.Wherein, preset time determines that rule may include a variety of, such as the local zone time of some node can be determined as required
The time of some equipment outside block chain can also be determined as the required time by the time wanted.
103, the current time is returned to the requesting party for sending the time acquisition request by intelligent contract.
After intelligent contract determines the current time of block chain, which can be returned into requesting party, to request
Root carries out subsequent logic processing according to the current time.
The determination method of time in block chain provided in an embodiment of the present invention can be needed in each node in block chain
When obtaining current time, the current time of respective local is not directly acquired instead of, it is unified to obtain current time to intelligent contract,
So that each node is synchronized in time.
Optionally, it is referred in above-mentioned steps 102, the method that intelligent contract determines current time has very much, below with following
It is illustrated for two kinds of determining methods.
Method one: it obtains this and executes the current time that block chain goes out the node local of block；Described this is executed into block
The current time that chain goes out the node local of block is determined as the current time of the block chain.
Wherein, there may be multiple block chains to go out block node (being commonly called as " mine machine ") in block chain, and each block chain goes out block section
The block of point write-in is different, and synchronization only one block chain goes out block node and goes out block (i.e. generation block).In order to enable area
This execution block chain is gone out node (the i.e. the last block out of block by the uniqueness of the current time of block chain, the embodiment of the present invention
Block chain go out block node) current time of local current time as block chain.
In practical applications, intelligent contract be potentially stored in this execute block chain go out on the node of block, it is also possible to store
On other nodes.Therefore obtaining the specific implementation of current time that this executes the node local that block chain goes out block can be with
Are as follows: when the intelligent contract of the requestor requests of acquisition time, which is located at this execution block chain, to be gone out on the node of block, intelligent contract
After receiving time acquisition request, local current time is directly read；When the intelligent contract is not located at this described execution
When block chain is gone out on the node of block, after the intelligence contract receives time acquisition request, block can be executed to described this
Chain goes out the node sending time acquisition request of block, then receive it is described this execute block chain go out block node feeding back it is current when
Between.
You need to add is that in practical applications, in addition to the local zone time for executing the node that block chain goes out block with this is made
It, can also be using the local zone time of other any nodes in block chain as the time of block chain outside time for block chain.
Method two: intelligent contract is first to the time server sending time acquisition request independently of the block chain, then
The current time that the time server returns is received, is finally determined as the current time that the time server returns described
The current time of block chain.
Due to being executed for block chain goes out the node local zone time of block relative to this, the time server meter of special timing
The time of calculation is more accurate, so closing if a intelligence for being able to access that the time server independently of block chain can be created
About, then current time preferentially is obtained using the intelligence contract.
Further, according to method described in intelligent contract side, another embodiment of the invention additionally provides a kind of area
The determination method of time, this method can be applied to the node of any one request time on block chain in block chain, such as Fig. 2 institute
Show, which comprises
201, when it needs to be determined that block chain current time when, to provide Time Service intelligent contract sending time obtain
Request determines the current time of the block chain so that the intelligent contract determines rule according to preset time.
When certain node it needs to be determined that when the current time of block chain, can to the intelligent contract being locally stored or this hold
Row block chain goes out the identical intelligent contract sending time acquisition request stored on the node of block, to receive when the intelligence contract
To after the time acquisition request, rule can be determined according to the time of default setting, to determine current time.Wherein, of the invention
Intelligent contract in embodiment can be the contract of special offer Time Service, be also possible to include Time Service and other services
Contract.But when the intelligence contract is the special contract for providing Time Service, the opposite efficiency of operation time includes it
The operation efficiency for the contract that he services often wants high, therefore provides the contract of Time Service it is preferable to use special.
202, the current time that the intelligent contract is sent is received.

So that each node is synchronized in time.
Further, in practical applications, certain node may need frequently to determine current time in special time period,
In this case, it if every time to intelligent contract acquisition time, operates comparatively laborious, it is lower to obtain efficiency.When in order to improve
Between obtain efficiency, after obtaining current time from intelligent contract side, the current time tune that can be sent according to the intelligent contract
Whole local current time, so that time synchronization.Thus subsequent can be directly from local acquisition time, without from intelligent contract
Side acquisition time.
However, as time goes by, the local zone time of node is often slack-off, such as in life, common computer is
Unite time (i.e. local zone time) with after network time synchronization, it is often slack-off after a period of time, lead to the system time of computer
It is asynchronous again with network time.In order to avoid causing the time used in each node to occur again because above situation occurs
It is asynchronous, it can first judge before the intelligent contract sending time acquisition request to offer Time Service according to the intelligence
Can the current time that sends of contract adjust after local current time by duration whether reach preset duration threshold value；If when described
Length reaches the preset duration threshold value, then sends the time acquisition request to the intelligent contract, to close from the intelligence
About side obtains current time；If the duration is not up to the preset duration threshold value, directly local current time is determined
For the current time of the block chain.Wherein, preset duration threshold value is determining based on practical experience node local zone time and intelligence
There is most growing in short-term for difference in the time of energy contract institute operation.
