Based on the description above, the embodiment of the present invention proposes a kind of data processing method, which can be by The first client and the second client in above-mentioned mentioned data processing system execute jointly.Fig. 3 is referred to, at the data Reason method may include following steps S301-S306:

First transaction data is uploaded to region chain network by S301, the first client.

First client first can create first key pair using rivest, shamir, adelman before executing step S301；This The rivest, shamir, adelman at place may include but be not limited to: Elgamal algorithm (a kind of rivest, shamir, adelman), Rabin algorithm (one Kind of rivest, shamir, adelman), Diffie-Hellman algorithm (a kind of rivest, shamir, adelman), ECC algorithm (elliptic curve cryptography Algorithm).Wherein, first key is to including the first public key and the first private key；First public key is for identifying the first of the first client Transaction address, the first private key sign to transaction data for the first client.In creation first key to later, first is objective First public key of first key centering can be uploaded to block chain network by family end, so that block chain network is by first key centering First transaction address of first public key as the first client, the first transaction address is for storing digital asset；And first is private Key is taken care of by the first client.It should be noted that the transaction address in block chain network is with uniqueness a, transaction Address corresponds to a client (i.e. user)；That is, the first public key can the first user indicated by the first client of label User identity.In another embodiment, the first client will also can be used to store the first man account of e-sourcing Account information (such as personal account number, personal account name) be uploaded to block chain network so that block chain network by this One personal account and the first public key are associated, and are used to manage and pay electricity using the first man account as the first client Address under the chain of child resource；Its specific implementation process can be together referring to fig. 4 shown in a.

After first public key is uploaded to block chain network by the first client, then show the first client in block chain network Identity registration is completed, the first client has the money that transaction in assets and information inspection are carried out in block chain network at this time Lattice.Therefore, the first client can upload the first transaction data to block chain network.In order to avoid the second client is receiving After digital asset, e-sourcing is not paid using the digital asset and to the first client, so that the first client be caused to damage The case where losing digital asset, the first client can constrain the use of digital asset in the first transaction data: unlock Before parameter is disclosed, the second client does not have the qualification using digital asset.It can be seen that the first transaction data can be used for Make region chain network that the digital asset of the first client is transferred to the second client, and the unlock parameter of digital asset not by Before open, control digital asset is in the lock state in the second client.Block chain network is receiving the upload of the first client The first transaction data after, the digital asset of the first client can be transferred to the second client according to first transaction data End, and before unlock parameter is not disclosed, in the second client-side lock digital asset so that the second client can not make With the digital asset, to ensure the equity of the first client.

S302, the second client check the first transaction data that the first client uploads in block chain network.

Second client first can also create the second key pair using rivest, shamir, adelman before executing step S302. Wherein, the second key pair includes the second public key and the second private key；Second public key is used to identify the second transaction ground of the second client Location, the second private key sign to transaction data for the second client.After creating the second key pair, the second client can Second public key of the second cipher key pair is uploaded to block chain network, so that block chain network is by the second of the second cipher key pair Second transaction address of the public key as the second client, the second transaction address is for storing digital asset；And the second private key is by The keeping of two clients.From the foregoing it will be appreciated that the transaction address in block chain network is with uniqueness, a transaction address correspondence One client (i.e. user)；Therefore, the second public key can second user indicated by the second client of label user identity.In In another embodiment, the second client will also can be used to store the account information of the second personal account of e-sourcing (such as Personal account number, personal account name etc.) it is uploaded to block chain network, so that block chain network is by second personal account and Two public keys are associated, with being used to manage and pay using second personal account as the second client under the chain of e-sourcing Location.

After second public key is uploaded to block chain network by the second client, then show the second client in block chain network In complete identity registration, the second client has the money that transaction in assets and information inspection are carried out in block chain network at this time Lattice.Therefore, the second client can check the first transaction data uploaded in the first client in block chain network.Second client End can decide whether to pay under starting chain, be determined whether payment for purchasing after checking and having verified the first transaction data Buy the e-sourcing of digital asset.If the second client is intended to the digital asset shifted using the first client, can start under chain Payment, step S303 can be performed in the second client at this time；If the second client is not desired to that chain can not be started using the digital asset Lower payment, process terminates at this time.

The condition of drawing of e-sourcing and e-sourcing is sent to mandatory system by S303, the second client.

After paying e-sourcing to the first client in order to avoid the second client, the underground unlock ginseng of the first client Number, the case where so as to cause the second client lost electrons resource；The producible e-sourcing of second client draws condition, should If drawing condition includes that unlock parameter is disclosed, the first client has the qualification for drawing e-sourcing.Then, the second client End the condition of drawing of e-sourcing He the e-sourcing can be issued mandatory system together, make mandatory system according to e-sourcing with The condition of drawing generates and uploads payment information to block chain network, and specific implementation process can be together referring to fig. 4 shown in b.Accordingly , mandatory system can receive the second client send e-sourcing and draw condition, by the e-sourcing received store to In trustship account, and according to e-sourcing and condition generation payment information is drawn, the payment information is then uploaded to block chain Network can be in block chain network in order to other node devices in the first client, the second client or block chain network Check the payment information.In one embodiment, payment information may include the numerical value of e-sourcing and draw condition；Another In kind embodiment, payment information may also include the second personal account that the second client pays the e-sourcing.

S304, the first client check the payment information that mandatory system uploads in block chain network.

From the foregoing it will be appreciated that payment information is according to the second client as mandatory system based on transmitted by the first transaction data E-sourcing and e-sourcing draw condition generation.Due to there is mandatory system to do credit endorsement, the first client without The actual value of the e-sourcing in the trustship account of mandatory system need to be verified, only need to check and verify the branch in block chain network Pay information.After checking and having verified payment information, if the first client is intended to draw the electronics money that the second client is paid Step S305 then can be performed in source；Otherwise, underground unlock parameter may be selected in the first client, and process terminates at this time.

S305, the first client will unlock parameter and carry out disclosure in block chain network, and electronics is drawn from mandatory system Resource.

Unlock parameter can be uploaded to block chain network to disclose the unlock parameter by the first client；Correspondingly, block chain The unlock parameter can be committed in shared account book, after receiving the unlock parameter so that in block chain network by network Each equipment (including the first client, the second client and mandatory system) can check the unlock parameter.Unlock parameter Once being disclosed, then mean that the e-sourcing in trustship account can not be withdrawn into the second client；And first client Holding has the qualification for drawing the e-sourcing.So the first client can draw the e-sourcing from trustship account.

S306, if unlock parameter is disclosed in block chain network by the first client, the second client uses unlock ginseng Number unlock digital asset.

From the foregoing it will be appreciated that the second client just has the qualification using the digital asset after unlock parameter is disclosed.Cause This, if unlock parameter is disclosed in block chain network by the first client, unlock parameter can be used to unlock number for the second client Word assets use the digital asset in order to subsequent.It should be noted that the specific implementation process of step S304-S306 may be used also Together referring to fig. 4 shown in c.

Fig. 5 is referred to, is the flow diagram of another data processing method provided in an embodiment of the present invention.This method can To be executed jointly by the first client and the second client in above-mentioned mentioned data processing system.Fig. 5 is referred to, the number May include following steps S501-S512 according to processing method:

S501, the first client create the unlock parameter of digital asset.

Unlock parameter herein can be the random number generated at random, be also possible to preset set by the first user Number；For convenient for illustrating, the embodiment of the present invention is subsequent to indicate unlock parameter with x.Unlock parameter is once disclosed, then will become chain Lower payment and chain submit the foundation being readily accomplished；That is unlock parameter is once disclosed, and the first client can draw e-sourcing, the Two clients can also unlock and use digital asset.After first client creation unlock parameter, it can be conciliate according to digital asset It locks parameter and generates the first transaction data, is i.e. execution step S502.

S502, the first client generate the first transaction data according to digital asset and unlock parameter.

Wherein, the first transaction data includes assets transfer data and asset control data；Assets transfer data are used to indicate The digital asset of first client is transferred to the second transaction ground of the second client from the first transaction address of the first client Location, if asset control data is used to indicate unlock, parameter is not disclosed, is controlled digital asset in the second client and is in locking State.

In one embodiment, the first client also can be used hash algorithm and carry out Hash operation to unlock parameter, obtain To target cryptographic Hash H (x)；Hash algorithm herein includes but is not limited to: MD4 algorithm, MD5 algorithm, SHA-1 algorithm, SHA-256 Algorithm, etc..Correspondingly, also the first transaction data can be generated according to digital asset, unlock parameter and target cryptographic Hash.Further In kind embodiment, the format of the first transaction data can be as follows:

Pay w units asset to<B’s public key>if(x for H(x)known and signed by B)

Wherein, w units indicates that digital asset, B indicate the second client, Pay w units asset to < B ' s Public key > expression payout figure assets are to the second transaction address；if(x for H(x)known and signed by B) Meaning are as follows: if the x (i.e. unlock parameter) for calculating target cryptographic Hash is disclosed, and the first transaction data is by B (the second client End) signature, then first transaction data can be spent by B (the second client), and the second client, which has, at this time uses the number The qualification of assets.

S503, the first client create the second transaction data according to the first transaction data.

Since the first transaction data can indicate that digital asset is transferred to the second client from the first client by block chain network End does not pay e-sourcing, always it would be possible that can have the second client after receiving digital asset so as to cause number Word assets are constantly in the second client, so that the case where the first client loses the digital asset.Therefore, in order to avoid this Situation, the embodiment of the present invention can be supported after some fixed time period, if the second client does not pay e-sourcing yet, Then the first client can ask for back the digital asset from the second client.Specifically, the first client can be according to the first transaction The second transaction data of data creation, the equity that the first client is further ensured that by second transaction data；Second friendship Easy data are used to indicate after default locking duration, if the second client does not have the qualification of unlock digital asset yet, Digital asset is transferred back into the first client from the second client.In one embodiment, the format of the second transaction data can It is as follows:

Pay w units asset from Tx1 to A, locked n+m hours

Wherein, Tx1 indicates that the first transaction data, A indicate the first client；N+m hours indicates default locking duration, n With the natural number that m is greater than zero；Locked n+m hours indicate by the second transaction data lock n+m hours, i.e., second After transaction data is uploaded in block chain network, by locked set time n+m hours；After the time expires, if the One transaction data is not spent yet, then shows that unlock parameter is not disclosed yet, i.e. the second client does not have unlock number money yet The qualification of production, the second transaction data will be performed automatically at this time, and block chain network will have been transferred in the first transaction data The digital asset of second client transfers back to the first client again.

Second transaction data is sent to the second client by S504, the first client, so that the second client is to second Transaction data is signed.

If needing to have transmitted to the digital asset of the second client again since the second transaction data is performed Transfer back to the first client, it is therefore desirable to which the second client signs to the second transaction data, to show that the second client terminates By second transaction data.Therefore, the first client the first private key can be used to hand over second after creating the second transaction data Easy data are signed, and the transaction data for carrying the signing messages of the first client is then sent to the second client.Accordingly , the second client can receive the second transaction data that the first client is sent.

S505 signs to the second transaction data if the second client receives the second transaction data.

Second client, can be in block chain network after receiving the second transaction data transmitted by the first client It checks the first public key of the first client, and the second transaction data is verified using the first public key, to judge second friendship Whether easy data are that the first client is created and sent.If verifying successfully, show that the second transaction data is by the first visitor Family end creates and sends；The second client can decide whether to receive the second transaction data at this time, if receiving, may be used second Private key signs to the second transaction data.

The second transaction data after signature is back to the first client by S506, the second client.

The second transaction data after signature can be back to by the second client after signing to the second transaction data First client, so that the second transaction data after signature is uploaded to block chain network by the first client.Correspondingly, first Client can receive the second transaction data after the signature that the second client returns.And the second transaction data after signature is uploaded To block chain network.In one embodiment, second transaction data of second client after it will sign is uploaded to block chain Before network, can also check the second public key of the second client in block chain network, and using the second public key to signature after Second transaction data is verified, to judge whether the second transaction data after the signature is that the second client is sent.If school Success is tested, then the step of the second transaction data after signature is uploaded to block chain network can be performed.

First transaction data is uploaded to region chain network by S507, the first client.

In the concrete realization, the first client can first sign to first transaction data using the first private key, then The first transaction data after signature is uploaded to block chain network；The first transaction data i.e. mentioned in step S507 carries the The signing messages of one client.Block chain network can make after the first transaction data for receiving the upload of the first client Proof of identity is carried out to first transaction data with the first public key, to judge whether first transaction data is in the first client It passes；If verifying successfully, show that the first transaction data is that the first client uploads, then block chain network can be according to intelligence Contract and common recognition mechanism execute the first transaction data, and the digital asset of the first client can be transferred to the second client, and Before unlock parameter is not disclosed, in the second client-side lock digital asset so that the second client is not available the number Word assets, to ensure the equity of the first client.After executing the first transaction data of completion, block chain network can will also be held Row result and the first transaction data are written in shared account book.It should be noted that the specific implementation process of step S501-S507 is also It can be shown in Figure 6 together.

S508, the second client check the first transaction data that the first client uploads in block chain network.

The condition of drawing of e-sourcing and e-sourcing is sent to mandatory system by S509, the second client.
