102, the digital asset exchange node judges whether the digital asset redemption request meets redemption of conditional.
After receiving digital asset redemption request, needs first to parse digital asset redemption request, therefrom obtain
Required data, then pre-set redemption of conditional, judges whether the digital asset redemption request meets the redemption of conditional, only
Have when meeting redemption of conditional, can just execute follow-up exchange operation.Pre-set redemption of conditional includes most basic exchange item
Part, according to the increased redemption of conditional of actual demand.Wherein, most basic redemption of conditional, which is exactly the type of former digital asset, to convert
It changes, the type of target number assets can exchange, the quantity of target number assets is enough；According to the increased exchange item of actual demand
Part includes digital asset redemption request side with exchanging permission, digital asset redemption request side with former digital asset to be exchanged into
Exchange permission of target number assets etc..
If 103, meeting the redemption of conditional, corresponding to the former digital asset storage to the former digital asset
In reserve assets account, and according between former digital asset and target number assets exchange proportion and the digital asset exchange
The quantity for asking Central Plains digital asset, feeds back to number by the digital asset in the reserve assets account corresponding to target number assets
Word assets exchange recipient.
When determining that digital asset redemption request meets redemption of conditional, digital asset exchanges node can be based on the original of storage
The address of the storage assets account of digital asset, by initiating the common area that transfers accounts to the block chain network belonging to former digital asset
The mode of block chain affairs (Transaction) is communicated with the block chain network, and former digital asset is stored and is arrived corresponding to it
Reserve assets account in, then according between former digital asset and target number assets exchange proportion and former digital asset
Quantity, determines the quantity of target number assets for needing to exchange, last digital asset exchange node by with target number assets
Affiliated block chain communication, takes out the digital asset of determining quantity from the corresponding reserve assets account of target number assets,
Then the digital asset of taking-up is fed back into digital asset and exchanges recipient.
In addition, the storage of digital asset and extraction operation can be by one in the affiliated block chain network of reserve assets account
Intelligent contract executes.Specifically, digital asset, which exchanges node, can be sent to the former digital asset the former number money
Intelligent contract in block chain network belonging to production, so that the intelligent contract stores the former digital asset to the former number
In reserve assets account corresponding to assets；Then according between former digital asset and target number assets exchange proportion and institute
The quantity of digital asset redemption request Central Plains digital asset is stated, determines the quantity for the target number assets for needing to exchange；Again by institute
The type and quantity for stating target number assets are sent to intelligent contract in the affiliated block chain network of the target number assets, with
Toilet states deposit money of the intelligent contract in the affiliated block chain network of target number assets corresponding to the target number assets
The target number assets of determining quantity are taken out in production account；It finally receives in the affiliated block chain network of the target number assets
The target number assets that send of intelligent contract, and the target number assets received are fed back into digital asset exchange and are connect
Debit.
Wherein, intelligent contract refers to that is defined in digital form be capable of the contract of automatic implementation of the provisions.In block chain technology
Field, intelligent contract refer in particular to the computer program for being triggered based on scheduled event, can not distorting, executing automatically.Intelligent contract is once
It generates, any one node can often call the intelligence contract in block chain, to realize a certain business or transaction.This hair
Intelligent contract in bright embodiment can be the special contract for providing digital asset access service, can also be including digital asset
The contract of access service and other services.But when the intelligence contract is the special contract for providing digital asset access service,
The access efficiency of the opposite contract including other services of its access efficiency often wants high, therefore provides number money it is preferable to use special
Produce the contract of access service.
It should be noted that it can be digital asset redemption request side that digital asset, which exchanges recipient, can also be number
The specified at least one recipient in assets redemption request side can also be that requesting party receives a part of digital asset, and specified connects
Debit receives a part of assets.That is, the digital asset exchange recipient include digital asset redemption request side and/or
The recipient that digital asset requesting party in addition to the digital asset redemption request side, described specifies.
The method that digital asset provided in an embodiment of the present invention is exchanged, can by can at least one block chain network into
Third party's node (i.e. digital asset exchanges node) of row interaction receives the digital asset that digital asset redemption request side is sent and converts
Request is changed, and when determining that digital asset redemption request meets redemption of conditional, it can be by the former number in digital asset redemption request
In word asset store to the reserve assets account corresponding to it, then according to converting between former digital asset and target number assets
The quantity for changing ratio and the digital asset redemption request Central Plains digital asset, by the reserve assets account corresponding to target number assets
Digital asset in number feeds back to digital asset and exchanges recipient, to realize that automation is exchanged, without being based on third party's reality
Body place, is exchanged by manual negotiations, and then simplifies exchange flow, improves exchange efficiency.
Further, method shown in FIG. 1, an alternative embodiment of the invention additionally provide a kind of exchange of digital asset
Method, as shown in Fig. 2, the method includes：
201, digital asset exchanges node and receives digital asset redemption request.
When user wants to exchange digital asset, block chain client can be logged in, then the number money to be exchanged of input
The type of quantity and target number assets is produced, clicks and exchanges button, triggering block chain client call digital asset exchanges node
Exchange interface, and by the exchange interface to digital asset exchange node send digital asset redemption request so that digital
Assets exchange node and pass through the exchange interface to digital asset redemption request.
202, the digital asset exchange node judges whether the digital asset redemption request meets redemption of conditional.
Redemption of conditional that redemption of conditional includes most basic is referred in above-mentioned steps 102, according to the increased exchange of actual demand
Condition.If current redemption of conditional only includes most basic redemption of conditional, judge whether the digital asset redemption request is full
The specific implementation of sufficient redemption of conditional can be：The digital asset exchanges the type that node judges the target number assets
Whether belong to the digital asset and exchanges the type for allowing to exchange in the block chain network that node is managed；If belonging to, basis
The number of exchange proportion and digital asset redemption request Central Plains digital asset between former digital asset and target number assets
Amount, determines whether the digital asset stored in the reserve assets account corresponding to the target number assets meets quantity demand；
If meeting the quantity demand, it is determined that the digital asset redemption request meets the redemption of conditional；Otherwise it (is not belonging to permit
Perhaps the type exchanged, or it is unsatisfactory for quantity demand), determine that the digital asset redemption request is unsatisfactory for the redemption of conditional.
When current redemption of conditional further includes other restrictive conditions, it can be further continued for judging whether to meet the requirements.If such as
Different grades of user, the digital asset type that can be exchanged is different, then can continue to judge whether active user has exchange
The permission of target number assets, if talented determination meets redemption of conditional.
If 203, meeting the redemption of conditional, corresponding to the former digital asset storage to the former digital asset
In reserve assets account, and according between former digital asset and target number assets exchange proportion and the digital asset exchange
The quantity for asking Central Plains digital asset, feeds back to number by the digital asset in the reserve assets account corresponding to target number assets
Word assets exchange recipient.
If 204, being unsatisfactory for the redemption of conditional, the certain amount of former digital asset is returned into digital asset and is converted
Change requesting party.
In addition, in order to allow digital asset to exchange the actual demand that mechanism more meets block chain field personnel, number can be passed through
Word assets are exchanged node and are interacted with each block chain, are carried out to the digital asset that can participate in exchanging in each block chain network
Adjustment.Specifically, digital asset can be added into existing reserve assets account, or have from described according to actual demand
Digital asset is extracted in reserve assets account；And/or according to the actual demand, for block chain network addition deposit money
Account is produced, or existing reserve assets account is deleted from the block chain network.Can also in addition, digital asset exchanges node
The exchange proportion to timely update between various digital assets.
For example, certain digital asset having in reserve assets accounts is converted away mostly, still has be converted at present
Demand, therefore in order to allow follow-up exchange to be smoothed out, first some digital assets can be added into the reserve assets account.
For another example, a kind of digital asset is newly produced in certain block chain network, can is digital asset addition deposit account.
In practical applications, user has the demand that digital asset is exchanged inside the same block chain network, also has transregional
Block chain network carries out the demand of digital asset exchange, therefore the digital asset exchange node in the embodiment of the present invention can be at least one
A block network interacts.Both of these case is illustrated below.
Example one：The digital asset of the same block chain network is exchanged
User 1 wants the digital asset A1 in block chain A being exchanged into digital asset A2, and will exchange result and return to certainly
Oneself, which can be as shown in Figure 3.Specifically, user 1 is logged in by block chain client and to be registered on block chain A
Then block chain account inputs the type A2 of the quantity and target number assets of the digital asset A1 to be exchanged, click to exchange and press
Button, triggering block chain client call digital asset exchange the exchange interface of node, and by the exchange interface to digital asset
It exchanges node and sends digital asset redemption request；Digital asset exchanges node and receives digital asset redemption request and determine number
After assets redemption request meets redemption of conditional, by way of initiating common block chain affairs of transferring accounts to block chain A and block
Chain A is communicated, and by digital asset A1 storages to its corresponding reserve assets account, is then provided from the deposit of digital asset A2
The digital asset A2 that corresponding number is taken out in account is produced, finally exchange node by digital asset feeds back to user by digital asset A2
The 1 block chain account (the block chain account for initiating digital asset redemption request) on block chain A.
If in addition, the user 1 wants exchange result feeding back to user 2, exchanging flow can be as shown in Figure 4.Also
It is to say, compared with Fig. 3, the digital asset in Fig. 4 is exchanged node and exchanged after obtaining digital asset A2, needs digital asset A2 is anti-
It feeds block chain account of the user 2 on block chain A.
In addition, being pointed out in the detailed annotation of above-mentioned steps 103, the storage of digital asset and extraction operation can be by reserve assets accounts
One in block chain network belonging to number intelligent contract executes.In this case, it result will be exchanged returns to oneself and be
Fig. 3 can be changed to Fig. 5 by example, specific flow of exchanging.I.e. digital asset exchanges node and is receiving digital asset redemption request simultaneously
After determining that digital asset redemption request meets redemption of conditional, the intelligent contract on block chain A is called, it will be digital by the intelligence contract
In assets A1 storages to its corresponding reserve assets account, and corresponding number is taken out from the reserve assets account of digital asset A2
Digital asset A2, by digital asset A2 feed back to digital asset exchange node, finally by digital asset exchange node will be digital
Assets A2 feeds back to block chain account of the user 1 on block chain A.
Example two：The digital asset of transregional piece of chain network is exchanged
User 1 wants the digital asset A1 in block chain A being exchanged into the digital asset B1 in block chain B, and will exchange
As a result oneself is returned to, which can be as shown in Figure 6.Specifically, user 1 logs in block by block chain client
Then the block chain account registered on chain A inputs the type B1 of the quantity and target number assets of the digital asset A1 to be exchanged,
It clicks and exchanges button, triggering block chain client call digital asset exchanges the exchange interface of node, and passes through the exchange interface
Node, which is exchanged, to digital asset sends digital asset redemption request；Digital asset exchanges node and receives digital asset redemption request
And after determining that digital asset redemption request meets redemption of conditional, by initiating common block chain affairs of transferring accounts to block chain A
Mode is communicated with block chain A, by digital asset A1 storage to its corresponding reserve assets account, then by block
The mode that chain B initiates common block chain affairs of transferring accounts is communicated with block chain B, from the reserve assets account of digital asset B1
The middle digital asset B1 for taking out corresponding number finally exchanges node by digital asset and digital asset B1 is fed back to user 1 in area
Block chain account on block chain B.
If in addition, the user 1 wants exchange result feeding back to user 2, exchanging flow can be as shown in Figure 7.Also
It is to say, compared with Fig. 6, the digital asset in Fig. 7 is exchanged node and exchanged after obtaining digital asset B1, needs digital asset B1 is anti-
It feeds block chain account of the user 2 on block chain B.
By above-mentioned exchange flow it is found that when transregional piece of chain network carries out digital asset exchange, result will be exchanged and returned
To oneself not being that will exchange result to return to the block chain account that request is exchanged, but the exchange result is returned into the user and is existed
Account on another block chain.For example, Fig. 5 refers to converting the digital asset A1 in account that user 1 registers on block chain A
Digital asset B1 is changed into, in the account for then registering digital asset B1 storages on block chain B to the user 1.Similarly, it exchanges
As a result it is also to be to return in account of another user on another block chain to return to another user.
In addition, if the storage of digital asset and extraction operation can be by one in the affiliated block chain network of reserve assets account
A intelligence contract executes, then in this case, for will exchange result and return to oneself, specific flow of exchanging can general
Fig. 6 is changed to Fig. 8.I.e. digital asset exchanges node and is receiving digital asset redemption request and determining that digital asset redemption request is full
After sufficient redemption of conditional, call the intelligent contract on block chain A, by the intelligent contract on block chain A by digital asset A1 storages to
In its corresponding reserve assets account；Digital asset exchanges the intelligent contract on node calling block chain B, by block chain B
Intelligent contract takes out the digital asset B1 of corresponding number from the reserve assets account of digital asset B1, and digital asset B1 is fed back
Node is exchanged to digital asset；Node is finally exchanged by digital asset, digital asset B1 is fed back into user 1 on block chain B
Block chain account.
It can be managed by individual you need to add is that digital asset in the various embodiments described above exchanges node, it can also be by
Decentralization group manages, and the quantity and mode of management of specific manager can be depending on actual demands.
