Summary of the invention

The inventors discovered that in the prior art, existing block platform chain is executed by transaction single machine, single machine stores, single The reasons such as the common recognition efficiency of block chain are unable to satisfy user and frequently hand under causing the transaction performance of block platform chain all relatively low Easy demand.Also, in existing technical solution, different traffic contracts is used between each block platform chain, so that each block Timing transaction task in chain is also only capable of executing in the block platform chain where respective, leads to not in a block platform chain High-frequency execution timing transaction task.

In view of above content, basic thought of the invention is: by being in advance that main chain distributes corresponding side chain, a side Face can be such that side chain is monitored in real time in main chain submission and the transaction of cochain；It, will and after listening to main chain and submitting timed task The original user state synchronized of main chain allows side chain to execute corresponding timed task, to realize main chain to side chain Timed task is automatically transferred to specified side chain and executes, the low problem of effective solution main chain timed task execution efficiency.It is another Fermentation is further subtracted by the way that the User Status after execution timed task is synchronized to main chain after side chain stop timing task The transaction total amount of few main chain, reduces the transactional overhead of main chain, and promote transactions velocity.

After introduced the basic principles of the present invention, lower mask body introduces various non-limiting embodiment party of the invention Formula.

Illustrative methods

The timed task dispatching party based on block chain of illustrative embodiments according to the present invention is described below with reference to Fig. 1 Method.

With reference to Fig. 1, the timed task dispatching method based on block chain be may comprise steps of:

S11, it is instructed in response to the task schedule to main chain, to start to carry out SM service monitoring to the main chain；

S12, timed task is being listened to after the main chain cochain, carry out original user state synchronized with the main chain, And the timed task is executed after synchronously completing with the main chain；

S13, in response to a task halt instruction, the User Status after timed task will be executed and be synchronized to the main chain；

S14, listen to it is described execution timed task after User Status be synchronized to the main chain after, terminate the timing Task.

In the timed task dispatching method based on block chain of embodiment of the present invention, by being in advance main chain distribution pair The side chain answered allows side chain to monitor the transaction submitted in main chain in real time；And after listening to main chain and submitting timed task, it will lead The original user state synchronized of chain allows side chain to execute corresponding timed task, determines main chain to realize to side chain When task be automatically transferred to specified side chain and execute, the low problem of effective solution main chain timed task execution efficiency.And in side The User Status after execution timed task is synchronized to main chain after end of chain (EOC) timed task, and then reduces the transaction total amount of main chain, Reduce the transactional overhead of main chain.

In step s 11, it is instructed in response to the task schedule to main chain, to start to carry out business prison to the main chain It listens.

In the illustrative embodiments of the disclosure, for side chain, user can distribute corresponding side chain for main chain, To make side chain monitor submission on main chain and the transaction of cochain.Wherein, side chain can be by POS (Proof of Stake, equity prove), the block chain based on the common recognition such as BFT (Byzantine Fault Tolerance, Byzantine failure tolerance). Specifically, side chain may include connection-bridge, side chain contract and side chain timing contract actuator.Wherein, connection-bridge is as side A part of chain monitors each node of side chain to main chain block and transaction by connection-bridge.Side chain contract is then pair It should be in the contract of main chain traffic contract.Side chain timing contract actuator can be used for according to timing contract, and repeating query simultaneously executes timing Transaction.

Wherein, connection-bridge can have inquiry User Status function (quey status), execute isochronous transaction function (execute status status) and execution finish timer function (execute finish timing).It is specific next It says, above-mentioned inquiry User Status function is export status method (the export Status called in main chain contract Result).After side chain calls main chain deriving method, the user of all association user addresses (relate Address) can be exported State, and carry out the initialization of side chain contract User Status.Above-mentioned execution isochronous transaction function, i.e., it is main in calling main chain contract Chain synchronous regime (sync Status Status) method initiates isochronous transaction, the implementing result of side chain timer, i.e. side chain User Status result after executing timed task returns to the process of main chain.Meanwhile connection-bridge can also constantly monitor the same of main chain Step transaction, to determine whether synchronization succeeds.Above-mentioned execution finishes timer function, can call the timing that finishes in main chain contract Task (finish Timing) method, after the completion of the state synchronized of all users of side chain, it is fixed to finishing for main chain that side chain is initiated When task trade, to be properly completed the timed task of main chain.

Above-mentioned side chain contract corresponds to the contract of main chain traffic contract, may include that timed task is submitted in confirmation (sure Sumit Timing).On the submission timed task (sumit Timing) that connection-bridge listens to main chain is traded and is determined After chain, side chain initiates to execute the transaction for determining submission timed task by going out block node, and takes the parameter of the timed task of main chain (time Params), is submitted to side chain.

It is that can also configure the main chain contract for needing to monitor after main chain distributes corresponding side chain for side chain in block chain member Address and need block chain account to be used.In addition, a main chain can correspond to one or more side chain, i.e. the timing of main chain is appointed Business, which can be assigned at least one side chain, to be executed.Due to may include multiple contracts in main chain, then main chain contract and side chain be then It can be the relationship of multi-to-multi, wherein a contract in main chain can correspond to the side chain for executing its timed task.It Afterwards, which can be by connection-bridge, with side chain/trunking scheme to the transaction (watch_eth) of main chain and block (watch_ Block it) is monitored in real time.

Specifically, refering to what is shown in Fig. 2, side chain may comprise steps of main chain progress SM service monitoring:

Step S111 monitors the transaction of the submission timed task of the specified address of the main chain by connection-bridge to obtain its friendship Easy Hash；

Step S112 obtains the transaction for submitting timed task location in the main chain according to the transaction Hash Block, and corresponding cryptographic Hash is inquired according to the block head of the block；

Step S113 calculates Merkel tree cryptographic Hash according to the cryptographic Hash, and by the Merkel tree cryptographic Hash and institute The original Merkel tree cryptographic Hash in block head described in main chain is stated to be compared to judge the transaction for submitting timed task Whether in the main chain cochain.

In the illustrative embodiments of the disclosure, side chain can pass through monitoring main chain transaction (watch_eth) and block (watch_block) come determine main chain timer transaction generation and whether cochain.For example, side chain can pass through monitoring Main chain corresponds to the All Activity under traffic contract, to judge whether timed task transaction occurs.Also, side chain can also pass through prison The block head of all cochains of main chain is listened, and those blocks are added in side chain, proves (Simplified to be SPV Payment Verification, simple pay warrant).Specifically, side chain is determined what specified address was initiated listening to main chain When task transaction after, obtain the transaction Hash of the transaction；And existed by the transaction hash query main chain with obtaining the exchange Block.And side chain is inquired by the block head of monitoring main chain and obtains building Merkel tree (merkle in main chain block Tree the cryptographic Hash needed for), and Merkel tree Hash (merkle root hash) is calculated according to the cryptographic Hash；And by the calculating Merkel tree Hash compared with the original Merkel tree Hash in main chain block head, judge whether equal.Judging phase Whens equal, then prove that timed task transaction is existing in main chain, and cochain.If unequal, prove the transaction in master It is not present in chain or side chain data from the block head that main chain is downloaded has situations such as mistake.

In step S12, timed task is being listened to after the main chain cochain, carries out original user state with the main chain It is synchronous, and the timed task is executed after synchronously completing with the main chain.

It, can when side chain is listening to timed task after main chain cochain in the illustrative embodiments of the disclosure Corresponding timed task is executed in side chain by the original user state synchronized of main chain to side chain, and then after synchronously completing.

Specifically, refering to what is shown in Fig. 3, above-mentioned listening to timed task after the main chain cochain, with the master Chain carries out original user state synchronized
