As shown in figure 1, the embodiment of the present invention provides a kind of transaction of the distributed general ledger system based on block chain technology pinch Conjunction method, is applied to a kind of trade match system 20 as shown in Figure 2, the trade match system 20 include seller terminal 201, Buyer terminal 202 and the distributed general ledger system 203, the distributed general ledger system 203 are included in the range of different tissues Multiple working nodes 204；The seller terminal 201 and buyer terminal 202 respectively with 204 communication link of the plurality of working node Connect.Multiple action nodes in the range of different tissues herein can be the server of different banks, different exchanges Server etc., because multiple working nodes are in the different scope of organizations, will not be come by same tissue (such as one exchange) The digital asset of the control seller and buyer, digital cash etc., therefore increased the security that transaction is brought together.

Method shown in Fig. 1 includes：

Step 101, distributed general ledger system receive the transaction request information in seller terminal input.

Wherein, the transaction request information includes that the first input reference information and the first ownership transfer prove information；Institute Stating the first input reference information includes recorded seller transaction output content in distributed general ledger system.

Step 102, distributed general ledger system are according to the described first input reference information and the first ownership transfer permit Breath is verified to the transaction request information, and after determining that transaction is legal, exports assets information to be transacted and the first institute Jump condition of having the right information；By the transaction request information, assets information to be transacted and the first ownership transfer conditional information It is recorded in the background data base of distributed general ledger system.

Step 103, each working node inquire the transaction request information in platform database in the rear, and treat described Transaction assets information and the first ownership transfer conditional information are shown.

Step 104, distributed general ledger system to be received and receive Transaction Information what buyer terminal was input into.

Wherein, described receive Transaction Information include the second input reference information, the second ownership transfer prove information, the 3rd Input reference information and the 3rd ownership transfer prove information；Described second input reference information include assets information to be transacted with And the first ownership transfer conditional information；The 3rd input reference information includes recorded in distributed general ledger system buying Side's transaction output content.

Step 105, distributed general ledger system judge that second ownership transfer proves whether information meets first and own Power jump condition, and judge that the 3rd ownership transfer proves whether information is legal.

In the second ownership transfer, step 106, distributed general ledger system prove that information meets the first ownership transfer condition, And the 3rd ownership transfer, when proving that information is legal, exporting buyer is used for the assets information of transaction, and its corresponding seller Known second ownership transfer condition, and export the assets information to be transacted, and its 3rd institute known to corresponding buyer Have the right jump condition.

So, the seller pass through its known second ownership transfer condition, you can obtain buyer for conclude the business assets believe Breath.Meanwhile, buyer passes through its known 3rd ownership transfer condition, you can obtain the assets information to be transacted of the seller.

A kind of transaction match method of distributed general ledger system based on block chain technology provided in an embodiment of the present invention, its Can realize that transaction is brought together in distributed general ledger system, in the case where third-party platform is completely disengaged from, realize trade quotation, The functions such as quotation shows, transaction order matching, and during transaction order matching, the assets to be transacted of the seller are used for concluding the business with buyer Ownership of assets synchronously can transfer.Due to need not introduce in whole process of exchange third party carry out quotation displaying, fund trustship, Assets trustship, guarantee, Trading Authorization or signature, can save third-party Charge exchange cost in a large number.Further, since brining process together In can achieve the synchronous transfer of ownership of assets, i.e., " collect on delivery, collect on delivery ", in process of exchange, there is no credit risk, Depart from third-party platform simultaneously and can also avoid third-party credit risk.

In order that those skilled in the art is better understood by the present invention, with reference to instantiation, to do to the present invention Further elucidated above, as shown in figure 3, the embodiment of the present invention provides a kind of friendship of the distributed general ledger system based on block chain technology Easy match method, including：

Step 301, distributed general ledger system receive the transaction request information in seller terminal input.

Wherein, the transaction request information includes that the first input reference information and the first ownership transfer prove information；Institute Stating the first input reference information includes recorded seller transaction output content in distributed general ledger system.Herein, described point Recorded in cloth general ledger system seller transaction output content includes that the seller corresponding with the assets to be transacted has Assets, and the seller had the ownership transfer condition of assets.

For recorded seller transaction output content in distributed general ledger system, which is can come from distributed general ledger The transaction X carried out in system.Transaction X is output as：The corresponding seller of assets to be transacted has had assets, and described The seller has had the ownership transfer condition of assets.

For example, the seller has had assets and is：Digital asset a.And the ownership transfer condition that the seller has had assets can be with For providing the private key signature with the public key match of the seller (referred to herein as seller A).The seller has had the ownership transfer of assets The locking script of condition is：DUP HASH160<pubkhash_A>EQUALVERIFY CHECKSIG.

Cited in the first input reference information is the output of transaction X.

Whether recorded seller transaction output content described in step 302, the judgement of distributed general ledger system is at other Reference is transfused in transaction.

If the step 303 recorded seller transaction output content is not transfused to reference in other transaction, it is distributed The first ownership transfer of formula general ledger system operation proves the unblock script of information.

Wherein, first ownership transfer proves that information includes the private key signature that the public key with the seller matches.For example, First ownership transfer proves that the corresponding unblock script of information can be：<sig_A><pubk_A>.

Step 304, after the unblock script success for running the first ownership transfer and proving information, distributed general ledger system fortune The row seller has had the locking script of the ownership transfer condition of assets.

Wherein, the ownership transfer condition that the seller has had assets is to provide the private key label with the public key match of the seller Name.

If the locking script that step 305 seller has had the ownership transfer condition of assets runs successfully, distributed general ledger System determines that input of seller terminal this transaction can be quoted recorded seller transaction and be exported content.

Step 306, distributed general ledger system determine recorded seller transaction output content in distributed general ledger system In whether there is assets information to be transacted, and determine whether seller terminal have input the private key label matched with the public key of the seller Name.

If there are assets to be transacted in recorded seller transaction output content in the distributed general ledger system of step 307 Information, and seller terminal have input the private key signature matched with the public key of the seller, then distributed general ledger system determines that transaction is closed Method.

Step 308, distributed general ledger system export assets information to be transacted and the first ownership transfer conditional information；Will The transaction request information, assets information to be transacted and the first ownership transfer conditional information are recorded in distributed general ledger system Background data base in.

For example, assets information to be transacted can be digital asset a；

Herein, the first ownership transfer conditional information is that to shift the proprietorial output valve of assets to be transacted be predetermined Content, or the private key signature that the public key of offer and the seller matches.For example, the predetermined content can be a preset value, example Such as<Txout1>；And locking script corresponding with the private key signature that the public key of the seller matches can be：OUT1<Txout1> EQUAL IF ELSE DUP HASH160<pubkhash_A>EQUALVERIFY CHECKSIG ENDIF.

Wherein,<Txout1>It is that the transaction that seller A sets is exported, in the acceptance of offer transaction that buyer (counterparty) initiates Output is necessary for this value, and the content of the transaction output that buyer initiates is pair valency of this time transaction, i.e. digital cash b must be synchronous It is transferred to seller A under one's name.

Selectable, herein command code OUT1 not only limit take using transaction output 1, can with defining operation code OUT2, OUT3 ... uses the output 2 of transaction, output 3 ... to take.I.e. for a transaction input, multiple transaction can be corresponded to defeated Go out.

The first ownership transfer conditional information herein is to shift the proprietorial output valve of assets to be transacted in predetermined Hold, or the private key signature matched with the public key of the seller is provided, the purpose of so setting is, both can be in the transaction of buyer B Output valve obtains the ownership of assets to be transacted when meeting predetermined content, can be that seller A passes through to provide the public key with the seller again The private key signature for matching, so that complete the revocation that concludes the business.

Step 309, each working node inquire the transaction request information in platform database in the rear, and treat described Transaction assets information and the first ownership transfer conditional information are shown.

After step 309, can be with execution step 310 or step 312.

Step 310, distributed general ledger system receive the Transaction Reversal solicited message in seller terminal input.

Wherein, the Transaction Reversal request message includes the 4th input reference information and the 4th ownership transfer permit Breath；The 4th input reference information includes the assets information to be transacted and the first ownership transfer conditional information； 4th ownership transfer proves that information includes the private key signature that the public key with the seller matches.

Herein, the 4th input reference information can be the output in step 308.And the 4th ownership transfer proves information Corresponding unblock script can be<sig_A><pubk_A>.

Step 311, distributed general ledger system are according to the described 4th input reference information and the 4th ownership transfer permit Breath is verified to the Transaction Reversal solicited message, and after determining that Transaction Reversal request is legal, exports assets letter to be transacted Breath and the 4th ownership transfer conditional information.

The assets information to be transacted can be digital asset a；And the 4th ownership transfer conditional information can be provide with The private key signature that the public key of the seller matches, its corresponding locking script be：DUP HASH160<pubkhash_A> EQUALVERIFY CHECKSIG.

After step 311, step 312 is can also carry out.

Step 312, distributed general ledger system to be received and receive Transaction Information what buyer terminal was input into.

Wherein, described receive Transaction Information include the second input reference information, the second ownership transfer prove information, the 3rd Input reference information and the 3rd ownership transfer prove information；Described second input reference information include assets information to be transacted with And the first ownership transfer conditional information；The 3rd input reference information includes recorded in distributed general ledger system buying Side's transaction output content.Recorded buyer transaction output content in the distributed general ledger system includes using with the buyer In the assets of transaction, corresponding buyer has had assets, and the buyer has had the ownership transfer condition of assets.

For recorded buyer transaction output content in distributed general ledger system, which can come from distributed general ledger system The transaction Y carried out in system, transaction Y are output as：Buyer has had assets, and the buyer has had the institute of assets Have the right jump condition.

For example, it can be digital cash b that the buyer has had assets；The buyer has had the ownership transfer condition of assets Can be that the private key signature with the public key match of buyer (referred to herein as buyer B) is provided.The buyer has had the ownership of assets The locking script of jump condition is：DUP HASH160<pubkhash_B>EQUALVERIFY CHECKSIG.

Step 313, distributed general ledger system judge whether the second input reference information is transfused in other transaction Quote.

For example, this second input reference information can by other transaction in be transfused to reference (equivalent to other buyers Receive the transaction of seller A), or (can be found in above-mentioned steps 310 to step 311) is cancelled by seller A itself.

If the step 314 second input reference information is transfused to reference in other transaction, distributed general ledger system to Buyer terminal sends refuse information.

If the step 315 second input reference information is not transfused to reference, distributed general ledger system in other transaction Described in judging, whether recorded buyer transaction output content is not transfused to reference in other transaction.

If the step 316 recorded buyer transaction output content is not transfused to reference in other transaction, it is distributed The 3rd ownership transfer of formula general ledger system operation proves the unblock script of information.

Wherein, the 3rd ownership transfer proves that information includes the private key signature that the public key with buyer matches；Which solves Locking script can be<sig_B><pubk_B>.

Step 317, after the unblock script success for running the 3rd ownership transfer and proving information, distributed general ledger system fortune Row buyer has had the locking script of the ownership transfer condition of assets.

Wherein, the ownership transfer condition that the buyer has had assets is to provide the private key label with the public key match of buyer Name.It is DUP HASH160 which locks script<pubkhash_B>EQUALVERIFY CHECKSIG.

If the locking script that step 318 buyer has had the ownership transfer condition of assets runs successfully, distributed general ledger System determines that input of buyer terminal this transaction can be quoted recorded buyer transaction and be exported content.

Whether step 319, distributed general ledger system are judged in the second ownership transfer proof information containing predetermined interior The proprietorial output valve for shifting assets to be transacted of appearance, and judge whether the private key signature that the public key of buyer matches is legal.

Herein in the second ownership transfer proof information in step 319, if containing the preset value in step 308< Txout1>, and the second ownership transfer prove unblock script be<TRUE>, the private key signature that the public key of buyer matches closes Method, then can complete transaction and bring together.

The transfer containing predetermined content in the second ownership transfer proof information of step 320, distributed general ledger system is treated The proprietorial output valve of transaction assets, and the private key signature that matches of the public key of buyer legal when, output buyer is used for concluding the business Assets information, and its second ownership transfer condition known to the corresponding seller, and export the assets information to be transacted, and 3rd ownership transfer condition known to its corresponding buyer.

Specifically, the second ownership transfer condition is to provide the private key signature with the public key match of the seller, for example its Locking script is DUP HASH160<pubkhash_A>EQUALVERIFY CHECKSIG；The 3rd ownership transfer condition For providing the private key signature with the public key match of buyer, it is DUP HASH160 that for example which locks script<pubkhash_B> EQUALVERIFY CHECKSIG.

For the instantiation of above-mentioned seller A and buyer B, unblock script therein and locking script can adopt head sea orchid table Show the execution language based on storehouse of method.

Following command code can for example be preset：

DUP：Replicate stack top element；

HASH160：Stack top item carries out HASH twice, first uses SHA-256, then uses RIPEMD-160；

EQUAL：If two numbers of input are equal, 1 is returned, otherwise return 0；

EQUALVERIFY：If two numbers of input are equal, continue executing with, otherwise return 0, and marker transactions are invalid；

CHECKSIG：The signature of exchange must be effective signature of cryptographic Hash and public key, if true, return 1, no 0 is then returned；

BOOLOR：It is not 0 that two have one, and output 1 otherwise exports 0；

OUT1：Take the output 1 using transaction；

Following constant can be preset in this programme：

<pubk_A>：The public key of A；

<pubk_B>：The public key of B；

<pubkhash_A>：The public key of A carries out the result of HASH160 computings；

<pubkhash_B>：The public key of B carries out the result of HASH160 computings；

<sig_A>：The cryptographic Hash of transaction using A private key signed after result；

<sig_B>：The cryptographic Hash of transaction using B private key signed after result；
