Specific embodiment
To keep the purposes, technical schemes and advantages of this specification embodiment clearer, have below in conjunction with this specification
The technical solution of this specification embodiment is clearly and completely described in body embodiment and corresponding attached drawing.Obviously, described
Embodiment be only this specification a part of the embodiment, instead of all the embodiments.The embodiment of base in this manual, this
Field those of ordinary skill every other embodiment obtained without making creative work, belongs to this explanation
The range of book embodiment protection.
Below in conjunction with attached drawing, the technical solution that each embodiment of this specification provides is described in detail.
For the transaction that the account model based on state machine, user are sent, exists and obtained and retransmitted by other users
Possibility onto block chain, thus will cause being performed a plurality of times for transaction, and this attack is known as Replay Attack.In order to avoid weight
Attack is put, needs to take certain strategy.For example, ether mill (Ethereum) is the public affairs for having intelligent contract function of an open source
Block platform chain altogether handles ether mill intelligence by providing ether virtual machine (Ethereum Virtual Machine, EVM)
It can contract.In ether mill, each transaction that user sends must all be handed over comprising one from random number (nonce) value increased
Easily once being identified, the legal nonce value of the user can be from increasing, and the transaction containing same nonce is then considered as illegal transaction,
It prevents from resetting with this.
But there is a very big defect for this design in ether mill, that is, latter transaction has to wait for previous
Transaction just can be with into trading pit, that is to say, that transaction can only sequential processes, limit the concurrency of transaction in this way.For example,
After user M sends transaction T0 to same node, after the completion of T0 to be transacted can only be waited to be packaged block and handle, can just it be sent in
Transaction afterwards.It, also cannot be parallel before the untreated completion of T0 even if posterior transaction T1 and T0 do not have any dependence
Processing transaction T1, otherwise may cause transaction T0 be packaged into block failure, transaction T1 be successfully packaged, but verify nonce value failure
The case where generation.It can be seen that the design in ether mill is also the uniqueness to drop the business parallel cost to guarantee transaction
's.
In view of the above problems, the embodiment of the present application provides method, apparatus and the Department of Electronics of a kind of block chain parallel transaction
System can not only guarantee uniqueness of trading, but also be able to achieve transaction concurrency, to improve the performance of block chain transaction.

Transaction generation unit is added to two data fields in transaction data, for storing unique mark of first transaction
Know: the first transaction random number and the first transaction validity period.Wherein, transaction generation unit generates the first transaction of random string write-in
In random number, which is arranged using data field valid_until_block.Data field valid_until_
It is also effective that block indicates which block this currently transmitted transaction continues up to.For example the current block height of block chain is
100, the A that trades sets 120 for valid_until_block, then it represents that after the A that trades is sent to block chain network, directly
To block height be 120 before all effectively.That is, transaction A can be packaged into the block between 101~120；If worked as
Block height has been over 120, and the A that trades is packaged out block by block chain network not yet, then it represents that A is by block chain for transaction
Network is abandoned, and transaction A can will be never recognized.It can thus be seen that in block catenary system, using data field valid_
Until_block is very convenient rationally transaction validity period is arranged.
S103, transaction generation unit are inquired according to first transaction the first Hash of generating random number (hash) value first
It whether there is transaction cryptographic Hash identical with the first cryptographic Hash in transaction validity period；If there is (in fact, probability is very small),
A new cryptographic Hash is then regenerated, is identified if there is no then verifying this cryptographic Hash as the uniqueness of the first transaction.
S104, transaction generation unit trade the first transaction corresponding first transaction random number validity period, first with first
The information such as cryptographic Hash are written in the first transaction data.
First transaction data is sent block chain network by S105, transaction generation unit.
S106, transaction verification unit receive the first transaction data from block chain network, and will be within the first transaction validity period
It is described first transaction random number cache to local.
The uniqueness of S107, transaction verification unit the first transaction of verifying within the first transaction validity period.

Similar with step S102, the second transaction random number and the second transaction validity period are similarly the unique of the second transaction
Mark.Wherein, transaction generation unit generates in random string write-in the second transaction random number, using data field valid_
The second transaction validity period is arranged in until_block.
Optionally, the first transaction validity period and/or the second transaction validity period are less than first threshold.Wherein first threshold
For maximum value as defined in system.In the embodiment of the application, transaction validity period valid_until_block can be user
It is arranged, and valid_until_block is less than maximum value max_valid_until_block as defined in system.One
In the possible implementation of kind, maximum value max_valid_until_block as defined in system is set as 100, if user sets
The valid_until_block set is greater than or equal to 100, then prompts the valid_until_block of user setting unsuccessful.It is logical
The threshold value for crossing setting valid_until_block, can be to avoid the excessive influence system performance of random number buffer pool, to improve
The overall performance of region catenary system.
S203, transaction generation unit are inquired according to second transaction the second Hash of generating random number (hash) value second
It whether there is transaction cryptographic Hash identical with the second cryptographic Hash in transaction validity period；If it is present regenerate one it is new
Cryptographic Hash is identified if there is no then verifying second cryptographic Hash as the uniqueness of the second transaction.
S204, transaction generation unit breathe out the corresponding second transaction random number of the second transaction, the second transaction validity period, second
The information such as uncommon value are written in the second transaction data.
Second transaction data is sent block chain network by S205, transaction generation unit.
It should be noted that step S201-S205 and step S106-S107 be it is parallel, do not need waiting step
It is executed again after the completion of S106-S107, i.e., operation and the transaction verification unit pair of the described transaction generation unit to the second transaction
The operation of first transaction executes parallel.Likewise, block chain user can initiate multiple transaction parallel, it can reference
Step S101-S105 executes similar step to execute parallel with transaction verification unit, to improve the transaction of block chain
Performance.
Meanwhile as shown in Fig. 2, also executing following step after step S205:
S206, transaction verification unit receive the second transaction data from block chain network, and will be within the second transaction validity period
It is described second transaction random number cache to local.
The uniqueness of S207, transaction verification unit the second transaction of verifying within the second transaction validity period.
Wherein, whether transaction verification unit second transaction of verifying within the second transaction validity period is uniquely to trade.
The method and step of Fig. 1 and Fig. 2 is concluded, the method for the offer of the embodiment of the present application can be as shown in Figure 3.Wherein, it hands over
Easy authentication unit and transaction generation unit independent parallel execute respective step.Generation unit of trading is used to generate for each transaction
Respective unique identification, wherein unique identification includes the corresponding transaction random number of each transaction and transaction validity period, is traded simultaneously
