Furthermore, it is contemplated that realize block chain red packet application other schemes further include:

Using password, i.e., red packet promoter is arranged when creating red packet gets password, and will get password and inform target person Group, only knows that this is got the talent of password and can take the share of red packet away；Or

Using white list, i.e. white list is arranged when creating red packet in red packet promoter, thus only in the white list Station address in list can just take the share of red packet away.

However, for above-mentioned cryptography scheme, verifying when needing to save password for getting on block chain, and block chain On information be all open and clear (including transaction data body and the storage of intelligent contract), it means that owner, including malice Attacker can obtain information on chain, or even malice takes other people red packet away.

On the other hand, for white list scheme, although the problem of can solve malicious attacker, white name is collected Single work is an inefficient and troublesome thing, does not also meet use the logic of red packet, thus can hinder the popularization applied with It uses.

In step 205, red packet initiator terminal 100 is based on above-mentioned received red packet information and witness public key generated It creates red packet and provides transaction request.

Red packet provides transaction request and initiates red packet granting transaction to block chain network 120 for red packet initiator terminal 100, It includes at least one clause that red packet, which provides transaction request, each clause be used to transmit to block chain network 120 different parameters with Execute different functions.These at least one clauses operate in an atomic manner, that is, only when the equal successful execution of all clauses When, which just runs succeeded, on the contrary, any one clause's execution is unsuccessful, then the request executes failure.

In accordance with an embodiment of the present disclosure, red packet hair can be created according to the difference of the currency type of red packet in different ways Put transaction request.It will be understood by those skilled in the art that the currency type of red packet can be preset by system 10, it is also possible to by red Wrap promoter's input.

In some embodiments, when the currency type of red packet is default coin, the i.e. primary coin of block chain network 120, red packet granting Transaction request may include the first clause, which indicates primary coin form for the red packet contract in block chain network Red packet.For example, first clause can indicate that the currency type of the red packet is primary coin in Data field as described below.Or Person can also indicate that the red packet is primary coin form in other fields that red packet provides transaction request.Red packet contract is area That disposes on the node of block chain network 120 is used to execute the intelligent contract of red packet processing method 20 according to the present invention, Particular content be further described below.First clause for example may include To field, Value field and Data field. Wherein, To field is configured to include the address of red packet contract, for indicating that red packet provides transaction request to block chain network 120 Destination address；Value field is configured to include the red packet total amount in red packet information, is used to indicate from red packet promoter's Primary coin of the address to the address of red packet contract transfer red packet total amount；Data field is configured to include red in red packet information Packet type, red packet share total number and witness public key or the witness address derived from according to witness public key.

In further embodiments, the currency type of red packet be token, i.e., the block chain network 120 supported by corresponding intelligence When the contract coin of energy contract administration, red packet granting transaction request also needs to obtain the authorization of the contract address of the token to execute Red packet granting operation.In this case, it may include two clauses that red packet, which is provided in transaction request, a clause for realizing Red packet function, another clause for realizing token authorization.Specifically, it may include atomic operation that red packet, which provides transaction request, The first clause and the second clause, wherein the first clause for in block chain network red packet contract instruction token form it is red Packet, the second clause are used for the token to the address of red packet contract transfer red packet total amount.First clause and the second clause can be with Including To field, Value field and Data field.For example, first clause can indicate in Data field as described below The currency type of the red packet is the concrete type of contract coin and/or contract coin.Alternatively, can also red packet provide transaction request other Indicate that the red packet is the concrete type of contract coin form and/or contract coin in field.

Wherein, the To field of the first clause is configured to include the address of red packet contract, is used to indicate the mesh of the first clause Address；The Value field of first clause is configured as first predetermined value, such as zero, is used to indicate red packet and provides transaction request It is not primary coin form；It is total that the Data field of first clause is configured to include red packet type, red packet share in red packet information Number and witness public key or the witness address derived from according to witness public key.Wherein, from witness address is derived from by witness public key, Such as witness address can intercept partial bit from witness public key and obtain.It, can since witness public key is usually long To use witness address to be further reduced the data volume of the transaction sent to block chain network 120, the transaction of block chain is reduced Cost.In some embodiments, it includes red packet expired time or validity period which, which can be additionally configured to, the pet name, is stayed One or more of the message link saying information or being generated according to message information.Red packet contract receives red packet granting transaction and asks After asking, the contents processing of the Data field based on first clause red packet provides transaction request.

The To field that red packet provides the second clause of transaction request is configured to include the contract address of token, is used to indicate The destination address of second clause；The Value field of second clause is configured as second predetermined value, such as zero, is used to indicate second Clause does not execute to the contract address of token and transfers accounts；The Data field of second clause be configured to include red packet contract address and Red packet total amount in red packet information is used to indicate intelligent contract corresponding to the contract address of token to the address of red packet contract Shift the token of red packet total amount.The contract address of token is address of the token contract in block chain network 120, about token The particular content of contract will be further elucidated hereinbelow.

In general, executing resource since the transaction of block chain node processing needs to consume certain code in block chain network And storage resource, therefore the respective handling node of block chain network can collect certain tranaction costs as return.Common During block chain is realized, tranaction costs are paid by transaction initiator and are collected by transaction processing node, and transaction processing node is received The tranaction costs taken can be less than or equal to the tranaction costs of transaction initiator's payment.In this case, block chain network 120 When handling the red packet granting transaction request that red packet initiator terminal 100 is sent, deducting execution from the account of red packet promoter should Transaction fee needed for red packet granting transaction, and when the red packet for handling the transmission of red packet receiver terminal 110 gets transaction request, from The account of red packet receiver, which deducts, executes transaction fee needed for the red packet gets transaction.

However, in some realizations of the disclosure, the transaction fee that red packet granting transaction and red packet get transaction can be by Red packet promoter payment, that is, red packet issuer pays for red packet receiver since red packet receiver gets produced by red packet share Transaction fee.In this case, it can also include for taking for red packet receiver payment transaction that red packet, which is provided in transaction request, Third clause, it is atomic operation that third clause and red packet, which provide other clauses in transaction request,.

The mode for obtaining transaction fee depending on the currency type of transaction fee and the block chain node of processing transaction is different, third Sentence has a variety of different ways of realization.

In some implementations, transaction fee pays in the form of primary coin and handles the friendship that the block chain node of transaction obtains Easily take from red packet issuer.In this case, third clause is paid with primary coin to the address of red packet contract for executing The red packet that red packet receiver submits gets the transaction fee of transaction, and third clause includes To field, Value field and Data field. Wherein, the To field of third clause is configured to include the address of red packet contract, is used to indicate the destination address of third clause；The The Value field of three clauses is configured as total transaction fee needed for getting red packet, is used to indicate to the address of red packet contract and shifts The primary coin of total transaction fee；The Data field of third clause can be configured as empty or any default value.

In other realizations, transaction fee pays in the form of token and handles the friendship that the block chain node of transaction obtains Easily take from red packet issuer.In the case where this, third clause is paid with token to the address of red packet contract for executing The red packet that red packet receiver submits gets the transaction fee of transaction.The token can be identical token with the token of red packet currency type, It can be different token.For the sake of expression conveniently, the token for payment transaction expense is hereinafter referred to as transaction fee coin.The third Clause includes To field, Value field and Data field, wherein the To field of third clause is configured to include transaction fee coin Contract address, be used to indicate the destination address of third clause；The Value field of third clause is configured as third predetermined value, Third clause is used to indicate not transfer accounts to the execution of the contract address of transaction fee coin；The Data field of third clause is configured to include The address of red packet contract, red packet ID and total transaction fee needed for red packet is got, is used to indicate transaction fee coin contract and is initiated from red packet The address of person is equal to the transaction fee coin of total transaction fee to the transfer of the address of red packet contract, and transaction fee coin contract is the conjunction of transaction fee coin About intelligent contract corresponding to address.

In still other realization, transaction fee pays in the form of token and handles the friendship that the block chain node of transaction obtains Easily expense is not from red packet issuer but is automatically generated according to the underlying protocol of block chain network 120.In this case, it hands over The transaction fee that easy initiator includes in third clause is destroyed by block chain network 120, and handles the transaction of the node of the transaction Expense is that the node regenerates by block chain network 120.In this case, third clause is for executing with transaction fee coin to seeing The red packet that payment red packet receiver in card address submits gets the transaction fee of transaction.Third clause includes To field, Value field With Data field, wherein the To field of third clause is configured to include the contract address of transaction fee coin, is used to indicate third The destination address of sentence；The Value field of third clause is configured as third predetermined value, is used to indicate third clause not to transaction fee The contract address of coin executes and transfers accounts；The Data field of third clause is configured to include total transaction fee needed for getting red packet and sees The witness address demonstrate,proving public key or being derived from according to witness public key is used to indicate transaction fee coin contract from the address of red packet promoter to seeing The transaction fee coin that address transfer is equal to total transaction fee is demonstrate,proved, transaction fee coin contract is intelligence corresponding to the contract address of transaction fee coin Contract.Herein, since witness address is only used for the granting of the specific red packet and gets process, it can be considered that the field Be only used for instruction payment is the transaction fee of which red packet transaction.

It should be appreciated that above-mentioned first, second, and third clause that red packet is provided in transaction request represents three independent areas Block chain task.In other block catenary system, which, which provides transaction request, can pass through two or three transaction requests It realizes, the two or three transaction requests include the corresponding task in above-mentioned first, second, and third clause together.This Outside, it will be understood by those skilled in the art that the sequence of above-mentioned first, second, and third clause be not limited to it is described above suitable Sequence, but red packet can be appeared in any order and provided in transaction request.

After the red packet provides transaction request creation, in step 207, red packet initiator terminal 100 sends out the red packet It puts transaction request and is sent to block chain network 120 to be handled by block chain network 120.

As described above, in some implementations, the message information and/or the pet name of red packet promoter can be with other red packet information It is included in red packet together to provide in transaction request, such as included in the Data field of the first clause, and is sent to block link network Network 120.However, saving it in block chain network in the case where the information content of leaving a message is too long and will lead to operating cost height. On the other hand, message information is often without security requirement, therefore it is also not high to save it in the necessity in block chain network. In this case, in some realizations of method 20, it can not include message information that red packet, which provides transaction request, but, it is red Message information is uploaded to external interspace file system (IPFS) by packet initiator terminal 100, generates a message letter by IPFS The message of breath links, and shares the pet name of red packet issuer and/or the message of the message information to multiple candidate red packet receivers Link allows recipient to see the pet name and/or message information of issuer by accessing IPFS.

After the red packet that block chain network 120 receives the transmission of red packet initiator terminal 100 provides transaction request, in step 209 Transaction request is provided to the red packet to handle.

The useful intelligent contract in the various functions of realization is disposed in block chain network 120, these intelligent contracts are according to block The Lower level logical of chain is operated in execute corresponding function on each node of block chain network 120, and each intelligence contract can be with It is called by external node or other intelligent contracts thereby executing specific operation.Each intelligence contract is in block chain network 120 In have unique address, the node of block chain network 120 is when handling transaction request, according to clause's each in transaction request Destination address (such as address indicated by the To field of the clause in transaction request) calls corresponding intelligent contract to handle.

Fig. 3 shows processing red packet at the node of block chain network according to an embodiment of the present disclosure and provides transaction request A kind of flow chart of illustrative method of (step 209).

Such as

Shown in Fig. 3, red packet is received in the node (such as node 121-1 of Fig. 1) of block chain network 120 and provides transaction request After (step 2091), judge that the red packet is primary coin or token form according to the first clause that red packet provides transaction request first Red packet (step 2092).For example, the node of block chain network 120 can by the content in the Data field of the first words and expressions come Determine the currency type of red packet.Alternatively, the node of block chain network 120 can by red packet provide transaction request in other fields come Determine the currency type of red packet.For the red packet of primary coin form, the node of block chain network 120 calls red packet contract to be handled. The parameter processing of the Value field and Data red packet of red packet contract based on first clause provides transaction request, including storage The information such as red packet type, red packet share total number and witness public key or witness address, and shifted from the address of red packet sender Address (step 2093) of the primary coin to red packet contract.For the red packet of token form, the node of block chain network 120 in response to First clause calls red packet contract storage red packet type, red packet share total number and the information such as witness public key or witness address；It rings Token contract, i.e. intelligent contract corresponding to the contract address of token should be called in the second clause, executed from red packet sender's Operation (step 2094) of the address to the address of red packet contract transfer token.

In some embodiments, the node of block chain network 120 may also determine whether to pay red packet by red packet promoter Receiver gets the tranaction costs (step 2095) of red packet share, for example, can determine red packet provide transaction request in whether include Above-mentioned third clause.It, can be according to the in response to determining by red packet promoter's payment transaction expense (step 2095 is judged as "Yes") Destination address in the To field of three clauses judges that the tranaction costs are propped up by primary coin or in the form of transaction fee coin (step 2096) is paid, wherein transaction fee coin can be the digital cash with the token same type of red packet, be also possible to block chain Token different types of digital cash that network 120 is supported but with red packet.For in the form of primary coin pay tranaction costs, The node of block chain network 120 can call red packet contract execute from the address of red packet promoter shift the primary coin of total transaction fee to Operation (the step 2097) of the address of red packet contract.For the tranaction costs paid in the form of transaction fee coin, block chain network 120 Node transaction fee coin contract can be called to execute shift the transaction fee coin of total transaction fee from the address of red packet promoter and close to red packet Operation (the step 2098) of address about.Alternatively, in step 2098, block chain network 120 is not straight in some other realizations The address that transaction fee is transferred to red packet contract from the address of red packet promoter is connect, but is sold in entire block chain network 120 The transaction fee in the red packet granting transaction request of red packet promoter is ruined, and regenerates a fixed number to handle the node of the transaction Return of the transaction fee coin of amount as the node.In this case, the transaction fee and block link network that transaction initiator is paid The acquired transaction fee of the node processing transaction of network 120 can be incoherent.

In response to determining not by red packet promoter's payment transaction expense (step 2095 is judged as "No") or step 2097 Or 2098 run succeeded,

The process of Fig. 3 is transferred to step 2099, and instruction step 209 runs succeeded.On the contrary, if either step in 2091 to 2098 Failure is executed, such as due to network failure, account balance deficiency etc., then can indicate that step 209 executes failure in step 2099, To this, it will not go into details in the disclosure.

It will be understood by those skilled in the art that the process of Fig. 3 is only exemplary, the place of transaction request is provided red packet Reason is not limited to said sequence.For example, the place for collecting transaction fee is first carried out in block chain node in many block catenary systems Reason, in this case, step 2095 to 2098 can execute before step 2092.

After the process of Fig. 3 is completed, block chain network 120 can carry out common recognition to processing result and by the transaction record In the distributed account book that each node is saved, to this, it will not go into details herein.

Fig. 2 is returned, the red packet is successfully processed in response to block chain network 120 and provides transaction request, it is in step 211, red Packet initiator terminal 100 obtains the success confirmation message that transaction request is provided for the red packet from block chain network 120.The success Confirmation message includes red packet ID, and red packet ID and red packet granting transaction request are uniquely corresponding.

Here, in some implementations, red packet initiator terminal 100 can be inquired with polling mode to block chain network 120 The processing result (success or failure) of red packet granting transaction request.Alternatively, in other realizations, it can also be by block link network Network 120 sends the processing result to red packet initiator terminal 100, such as preparatory by red packet initiator terminal 100 or system 10 Processing result feedback system is set as " subscribing to ".

After red packet initiator terminal 100 obtains the success confirmation message, in step 213, at least one candidate red packet Receiver shares red packet ID wherein included and in step 203 witness private key generated.

Specifically, red packet initiator terminal 100 can get link and/or two dimension according to red packet ID and witness private key generation Then code will get link and/or two dimensional code be shared with candidate red packet receiver.

Red packet receiver gets link for example, by scanning the two-dimensional code or directly inputting using red packet receiver terminal 110, It parses the two dimensional code or gets link to obtain the red packet ID and witness private key that red packet initiator terminal 100 is shared.

Optionally, in some embodiments, red packet receiver terminal 110 can determine area based on red packet ID and witness private key It whether there is believable red packet information in block chain network 120.Specifically, in one embodiment, 110, red packet receiver terminal The first witness public key is calculated according to the witness private key of acquisition, and is obtained from block chain network 120 and red packet ID according to red packet ID Corresponding second witness public key.Then red packet receiver terminal 110 compares the first witness public key and the second witness public key, when It when the two is consistent, determines that there are believable red packet information in block chain network 120, that is, determines that red packet issuer is shared with red packet neck The red packet of taker necessary being in block chain network 120.In another embodiment, red packet receiver terminal 110 is according to obtaining The witness private key that takes calculates the first witness public key, to calculate the first witness public key corresponding the according to the first witness public key One witness address.In addition, red packet receiver terminal 110 is obtained from block chain network 120 and ID pairs of red packet also according to red packet ID The the second witness address answered.Red packet receiver terminal 110 compares the first witness address with the second witness address, when the two one It when cause, determines that there are believable red packet information in block chain network 120, that is, determines that red packet issuer is shared with red packet receiver's Red packet necessary being in block chain network 120.Specifically, the object compared is witness address or witness public key, is depended on The setting of system 10, the object compared are corresponding with the setting.

Herein, the method for public key is generated according to private key and/or block can be according to the method that public key generates address Chain field is currently known or any algorithm of following exploitation, realization of the invention are not limited to any specific algorithm or method.

Obtain red packet ID and witness private key after, in step 215, red packet receiver terminal 110 can by hash algorithm, Such as keccak256 algorithm is shown in the address calculation cryptographic Hash of red packet ID and red packet receiver, and with what red packet promoter shared Card private key signs to generate and get signature to the cryptographic Hash.It should be noted that the address to red packet ID and red packet receiver is counted Cryptographic Hash is calculated, refers to that the combination to both addresses of red packet ID and red packet receiver calculates cryptographic Hash, herein not to combined side Formula calculates the progress any restrictions of hash algorithm used in cryptographic Hash.

Then, in step 217, red packet receiver terminal 110 is based on red packet ID and gets signature creation red packet and get friendship Easily request.

Red packet get transaction request may include for shifted from the address of red packet contract the digital cash of certain amount of money to 4th clause of the address of red packet receiver, the 4th clause include To field, Value field and Data field, wherein the 4th son The To field of sentence is configured to include the address of red packet contract, is used to indicate the destination address that red packet gets transaction request；4th The Value field of clause is configured as the 4th predetermined value, such as zero, is used to indicate the 4th clause and is not used in ground to red packet contract Location executes and transfers accounts；The Data field of 4th clause be configured to include red packet ID, red packet receiver address and get signature.

In step 219, red packet receiver terminal 110 by red packet get transaction request be sent to block chain network 120 with The red packet share of the red packet is got in request.

Here, in step 219 or before step 219, red packet receiver terminal 110 can also utilize witness private key Transaction request is got to the red packet created to sign, and the red packet with the signature is got into transaction request and is sent to block 120 (not shown) of chain network.In this case, verifying red packet is used directly for using the signature that witness private key generates Get whether transaction request is that legal red packet gets request.For example, the node of block chain network 120 can be to receive this red After packet gets transaction request, the signature in transaction request is got according to the red packet and decrypts witness address, and address will be witnessed It is compared with the witness address stored in block chain network 120 to verify the red packet and whether get transaction request from legal Address.

After receiving the red packet and getting transaction request, in step 223, the node of block chain network 120 (such as Fig. 1 Shown in node 121-2) verify to getting signature.

Specifically, the red packet contract address in To field of the node of block chain network 120 based on the 4th clause is called red Inclusion is about verified to getting signature.For example, red packet contract can the address first to red packet ID and red packet receiver breathe out Operation is wished to generate the first cryptographic Hash, utilizing stored witness public key to get red packet, transaction request is corresponding above-mentioned to get label Name is decrypted to obtain the second cryptographic Hash, is compared to the first cryptographic Hash and the second cryptographic Hash to verify this and gets signature. When the first cryptographic Hash is consistent with the second cryptographic Hash, gets signature verification and pass through, otherwise verify and do not pass through.If getting signature to test Card does not pass through, then returns to Fail Transaction to red packet receiver terminal 110.

Preferably, the node in block chain network 120 receives red packet and gets and carries out to getting signature after transaction request Before verifying, whether effectively method 20 can also include: to examine red packet state (step 221).Specifically, block chain network 120 Node it is executable following operate it is one or more: check that red packet ID whether there is, check whether red packet expired, check red Packet does not get whether share number is 0, and judges whether red packet receiver not yet got the red packet share of the red packet. In some embodiments, the red packet contract of block chain network 120, which can be set, has got address list and will successfully get red packet The address of the red packet receiver of share is added and has got in address list.After receiving red packet and getting transaction request, check that this is red The address of receiver is wrapped whether in having got address list, if not getting address list, it is determined that the red packet is got Person not yet got the red packet share.

Next, the red packet contract in block chain network 120 calculates what red packet receiver should get according to red packet information Red packet share (step 225).For example, in one implementation, red packet contract can determine the red packet class of the red packet based on red packet ID Type is respectively red packet.In this case, the red packet total amount that red packet contract calculates in red packet information is always a divided by red packet share Red packet share of several quotient as each red packet, that is, the red packet share that red packet receiver should get.In another example in another kind In realization, red packet contract can determine that the red packet type of the red packet is random red packet based on red packet ID.In this case, red packet Remaining red packet share number that contract is stored at the node according to block chain network 120 and remaining red packet total amount it is determined that Distribute to the red packet share of red packet receiver.For example, specifically, it, will be remaining in the case where remaining red packet share number is 1 Red packet total amount is fully allocated to red packet receiver.And in the case where remaining red packet number is greater than 1, it is always golden from remaining red packet Take a value as the red packet share that distribute to red packet receiver in volume at random.

Next in step 227, the red packet contract of block chain network 120 is by the number of red packet share determined by step 225 Word currency is transferred to the address of red packet receiver.

Method 20 can also include step 229, wherein being transferred to red packet in the red packet share that should get red packet receiver After the address of receiver, the address of red packet receiver is recorded the red packet contract of block chain network 120 has got address column In table, and update remaining red packet total amount and remaining red packet share number.
