Digital signature, and the specific amount of money of the currency of additional issue is only indicated in its transaction output.For example, if in block catenary system
Node 121 into Fig. 1 has been issued additional 12.5 yuan of currency, is placed in the transaction output of wound generation block.Then for node 121
For, have the right of eminent domain of this 12.5 yuan of currency, the output of this 12.5 yuan of currency can be used as the friendship of next transaction
Easily input, as its name suggests, this transaction output are just referred to as to be that node 121 does not spend output, that is, node 121A
The meaning of UTXO.In an embodiment of the present invention, wound generation block is usually and each money transfer transactions in the embodiment of the present invention
The source of associated block.But since wound generation block is a kind of special block, herein mainly for
General block is described.
Fig. 3 instantiates the flow chart of the method 300 of the processing money transfer transactions based on block chain.
In step 301, at first node equipment, in the New Transaction that initiation only transfers accounts to second node equipment
When, the first block associated with the New Transaction is created in the first block chain associated with first node equipment, wherein should
First block chain only record it is associated with the first node equipment transaction (including by the first node equipment initiation transfer accounts
Transaction or the transaction transferred accounts to first node equipment) Transaction Information.
The first block packet associated with the New Transaction is created in the first block chain associated with first node equipment
Include: generating one or more transaction inputs of the New Transaction in first block, wherein one or more transaction input and
The transaction output that the one or more selected from the first block chain is not spent corresponding and wherein selected one or
The summation of the remaining sum of multiple transaction outputs not spent is greater than or equal to the amount of money of the New Transaction；It is raw in first block
At the first transaction output and the second transaction output of the New Transaction, wherein the first transaction output is related to first node equipment
Connection, the second transaction output are associated with second node equipment.Each transaction in one or more transaction input inputs packet
Include: block hashed value, the block hashed value are used to indicate including inputting the corresponding transaction output not spent with the transaction
Address of the previous block in the first block chain；Output serial number is not spent, and it is previous that this does not spend output serial number to be used to indicate this
Serial number of the transaction output not spent in the previous block；And digital signature, the digital signature are first node equipment
Signature to indicate that transaction input is generated by first node equipment.First transaction output and the second transaction output are all wrapped
Recipient address and remaining sum are included, wherein the recipient address of the first transaction output is the first address of first node equipment, and
And its remaining sum is first node equipment the first remaining sum associated with New Transaction, which is by by this or more
The amount of money that the summation of the remaining sum of a transaction output not spent subtracts the New Transaction is next calculated, and wherein second hands over
The recipient address easily exported is the second address of second node equipment, and its remaining sum is second node equipment and the new friendship
Easy associated second remaining sum, the second remaining sum are equal to the amount of money of the New Transaction.In an embodiment of the present invention, this or
Multiple transaction inputs are all the tissue in the form of array in the first block, therefore each transaction input is in first block
In all have a corresponding serial number, in addition first transaction output and second transaction output in first block be also with number
The form tissue of group, thus the first transaction output and the second transaction output also all have in the first block one it is corresponding
Serial number.
For example, when first node equipment transfer accounts to second node equipment the transaction of 55 yuans, first node equipment
The firstth area associated with the money transfer transactions of 55 yuan can be created in the first block chain associated with first node equipment
Block.For the transaction, first node equipment, which for example has selected from the first block chain, can be used for two of the transaction and does not spend
Transaction output, for example, the transaction that does not spend of first with 50 yuan of remaining sums in third block export and the 4th block in
Second with the 10 yuan of remaining sums transaction output not spent.Therefore, first node equipment can generate the friendship of transferring accounts in new block
Easy two transaction input, wherein first transaction input includes the area of address of the instruction third block in the first block chain
Serial number of the transaction output that block hashed value, instruction first are not spent in third block does not spend output serial number and instruction
The digital signature of the signature of the first node equipment.The block hashed value of second transaction input includes that the 4th block of instruction exists
Serial number of the transaction output that the block hashed value of address in first block chain, instruction second are not spent in the 4th block
Output serial number is not spent and indicates the digital signature of the signature of the first node equipment.
In this example, first node equipment can also generate two transaction output of the money transfer transactions in new block,
In first transaction output recipient address be first node equipment the first address, and remaining sum be 5 yuan of (i.e. two aboves
60 yuan of summation of the remaining sum for the transaction output not spent subtract 55 yuan of the total amount of the money transfer transactions), the second transaction output connects
Debit address is second node equipment, and remaining sum is 55 yuan of (amount of money transferred accounts in the money transfer transactions to second node equipment
55 yuan).
In addition, it is noted that when such as first node equipment needs to transfer accounts to second node equipment, if with
In the presence of the multiple and different friendships not spent that can meet the amount of money transferred accounts in the associated first block chain of first node equipment
Easily output then can be exported optionally in one or more transaction not spent, as long as the transaction output not spent selected
The summation of remaining sum is greater than or equal to the amount of money of the money transfer transactions.
The first block associated with the New Transaction is created also in the first block chain associated with first node equipment
It include: to be used to indicate the block hashed value of address of first block in the first block chain for the distribution of the first block, and the
Addition is used to indicate the father's block hashed value for father's block that the first block is quoted in the first block chain in one block.
In step 302, at first node equipment, the public key of the first block and first node equipment is sent to
Second node equipment.In one implementation, which is curve public key.
In step 303, at second node equipment, after receiving first block and public key, the public key is utilized
Sign test is carried out to first block, whether to verify the first block actually from the first node equipment.
In step 304, at second node equipment, the first block is being verified actually from the first node equipment
In the case where, the second block is created in the second block chain associated with second node equipment.Otherwise, it is set to first node
Preparation makes mistake message (not shown).
Creating the second block in the second block chain associated with second node equipment includes: to be wrapped the first block
The one or more transaction inputs included are added to one or more transaction inputs in the second block as the second block；By
First transaction output and the second transaction output included by one block are added in second block the as the second block
One transaction output and the second transaction output.
In step 305, at second node equipment, one or more transaction inputs of the second block are carried out effective
Property verifying.In one implementation, carrying out validation verification to one or more transaction inputs of the second block includes: by one
Trace the mode of wound generation block related with institute's New Transaction up directly to verify one or more inputs of trading of the second block
Validity indicate this or more and in the case where any wound generation block related with the New Transaction can not be traced back to
A transaction input is invalid.For example, node device B needs to verify should when node device A carries out money transfer transactions to node device B
The legitimacy of money transfer transactions, such as first to trace any transaction input with the money transfer transactions one associated by node device B
Or multiple transaction outputs (these transaction not spent output in the block chain of node device A) not spent, it is verified this
The transaction that do not spend export in all effective situations a bit, can it is each do not spend transaction to export on the basis of determine and do not spent with this
Take one or more transaction inputs of the transaction output in same block, is then based on one or more transaction input retrospect
One or more associated with each transaction input does not spend transaction output (for example, the transaction that the one or more is not spent
Output can for example in the block chain of node device C, but may also be again in the block chain of two or more node devices),
It, can similar method as described above and in the case where each transaction that does not spend traced back to exports all effective situation
It further up traces, all original blocks related with the transaction until tracing back to the source as transfer amounts are
Only.In the case where the original block as source can be traced back to, show that the transaction is effective.
Within step 306, at second node equipment, in the effective of one or more transaction inputs to the second block
In the case that property is verified, the successful message of the New Transaction is sent to first node equipment.Otherwise, to first node equipment
Send the New Transaction failure news (not shown).
Although in the fig. 3 embodiment, to occur over just the friendship of transferring accounts between first node equipment and second node equipment
Easily for the present invention is described, but should be appreciated that the embodiment of the present invention be also applied for a node device to two or
The case where other more than two node devices carry out money transfer transactions.Only in these cases, such as when being related to first node it sets
It is standby when being transferred accounts to second node equipment and third node device, first node equipment at the block that creates will include
Three transaction outputs, i.e., a transaction associated with first node equipment are exported and are set respectively with second and third node
Standby associated two transaction export.Also, the block created at first node equipment will be sent to second and third
Both node devices, and the transaction input of two other to this respectively node devices is needed to verify.For example,
When one node device transfer accounts 55 yuans to second node equipment and transfer accounts 20 yuan of transaction to third node device, first
Node device can create the firstth area associated with the money transfer transactions in the first block chain associated with first node equipment
Block.For the transaction, first node equipment, which for example has selected from the first block chain, can be used for two of the transaction and does not spend
Transaction output, for example, the transaction that does not spend of first with 50 yuan of remaining sums in third block export and the 4th block in
Second with the 30 yuan of remaining sums transaction output not spent.Therefore, first node equipment can generate the friendship of transferring accounts in new block
Easy two transaction input, wherein first transaction input includes the area of address of the instruction third block in the first block chain
Serial number of the transaction output that block hashed value, instruction first are not spent in third block does not spend output serial number and instruction
The digital signature of the signature of the first node equipment.The block hashed value of second transaction input includes that the 4th block of instruction exists
Serial number of the transaction output that the block hashed value of address in first block chain, instruction second are not spent in the 4th block
Output serial number is not spent and indicates the digital signature of the signature of the first node equipment.In this example, first node equipment
Three transaction output of the money transfer transactions can be also generated in new block, wherein the recipient address of the first transaction output is the
First address of one node device, and remaining sum is 5 yuan of (summations 80 for the remaining sum that the transaction that i.e. two above is not spent exports
Member subtracts 75 yuan of the total amount of the money transfer transactions), the recipient address of the second transaction output is second node equipment, and remaining
Volume is 55 yuan (55 yuan of the amount of money transferred accounts in the money transfer transactions to second node equipment), the recipient of third transaction output
Location is third node device, and remaining sum is 20 yuan (20 yuan of the amount of money transferred accounts in the money transfer transactions to third node device).
The case where money transfer transactions are carried out to other more than two node devices for a node device can and so on.
In an embodiment of the present invention, since each node device only maintains block associated with the node device
Chain, incoherent node for the record based on transaction associated with the node device, therefore in block catenary system it
Between the incoherent transaction that occurs can concurrently execute, to improve the transaction handling capacity of block catenary system, especially work as area
When the number of node device in block catenary system is more, the transaction handling capacity in block catenary system is higher, so that transaction can be realized
Unlimited horizontal extension.
