Specific embodiment
To keep the purposes, technical schemes and advantages of this specification embodiment clearer, have below in conjunction with this specification
The technical solution of this specification embodiment is clearly and completely described in body embodiment and corresponding attached drawing.Obviously, described
Embodiment be only this specification a part of the embodiment, instead of all the embodiments.The embodiment of base in this manual, this
Field those of ordinary skill every other embodiment obtained without making creative work, belongs to this explanation
The range of book embodiment protection.
Below in conjunction with attached drawing, the technical solution that each embodiment of this specification provides is described in detail.
It should be noted that for side chain/relaying (Sidechains/relays) mode in across chain service, across chain side
Formula are as follows: assuming that thering is A chain and B chain to need to interact, but A chain and B chain can not intercommunications.At this moment a relaying Relayer energy can be set
A chain and B chain are read, then, which just as " on the chain " intermediary for linking A chain and B chain, is properly termed as " relaying ", entirely
It is exactly " A-C-B " across chain process.However, it is contemplated that in current across chain scheme or needing to believe the part relaying Relayer
Appoint, is biased to notary's mode；The setting for relaying Relayer is excessively complicated, such as: exist between multiple relaying Relayer
Competitive relation needs through mortgage token competition, and supervises and do evil by reporting.This specification embodiment simplifies relaying
The setting mechanism of Relayer, by setting across chain mutual concession for relaying after credible setting and having simultaneously to across chain both sides
The full node for going to trust of access authority, to realize simplified and safety across chain service between across chain both sides.
Embodiment one
Referring to Fig.1 shown in a, for step schematic diagram of a kind of block chain across chain method that this specification embodiment provides, institute
State across chain method apply under side chain/repeater mode across in catenary system, wherein across may include main chain, side chain in catenary system
And the relaying across chain service is provided for main chain and side chain, which can be an independent block chain node or is located at area
Functional module on block chain node.It should be understood that the block chain can be decentralization trading floor across the application scenarios of chain scheme
Scape or exchange of assets scene etc..
Across the chain method may comprise steps of:
Step 102: the lock that the first block chain where relaying reading underlying scenario generates after locking the underlying scenario
It is fixed to prove.
It should be understood that the first block chain can be across the side chain in catenary system, underlying scenario is provided on the side chain.Side
Chain can lock underlying scenario in across chain service process, be executed with freezing or suspending underlying scenario on side chain except this
Other assets transaction except secondary across chain transaction.
Step 104: locking proof is sent to the second block chain by the relaying, and the locking is proved for triggering
It states the second block chain to verify locking proof, and generates mapping corresponding with the underlying scenario after being proved to be successful
Assets.
The second block chain can be across the main chain in catenary system, which can be by way of anchoring in itself institute
Mapping assets corresponding with underlying scenario are mapped on chain.For example, underlying scenario X on side chain, can generate mapping on main chain
Assets X '；Wherein, underlying scenario X can be equal with the value of mapping assets X '.
Wherein, the relaying is to go to trust with access authority to the first block chain and the second block chain
Full node.
It should be noted that relaying can be online lower determination, which can have visit to main chain and side chain simultaneously
Ask permission, in other words, relaying can be the full node of main chain and side chain simultaneously.Full node refers to that maintenance includes all transaction letters
The node of the intact block chain of breath, the node can verify any Transaction Information independently, without by it is any its
Its node or other information.
In this specification embodiment, relaying can not forge Transaction Information, only the locking of trading activity be submitted to prove, institute
As long as the third party across chain mutual concession can be become to meet the condition of credible setting, the as full node of main chain and side chain
Across chain service is relayed and provided, does not need to go to generate the relaying that can be trusted by complicated means in the prior art, thus simple
The setting mechanism for changing relaying by going the relaying trusted to simplify across chain service, and promotes across chain transaction security.
Optionally, in actual across chain operation, underlying scenario can be locked in the first block chain, and in the second block chain
Mapping assets are generated, thus, the transfer of assets is realized, to carry out transaction in assets on the second block chain.In addition, in the secondth area
When the mapping assets that block chain generates do not need, it can be reversed and the first block chain, referring to Fig.1 shown in b, the side are returned into assets transfer
Method further include:
Step 106: the second block chain where the relaying reading mapping assets is after destroying the mapping assets
The unlock of generation proves.
Step 108: unlock proof is sent to the first block chain by the relaying, and the unlock is proved for touching
It sends out the first block chain described and unlock proof is verified, and unlock the underlying scenario after being proved to be successful.
Optionally, the locking proves to carry at least one block checkpoint of the first block chain；
When the second block chain verifies locking proof, specifically include: the second block chain is to described
Locking prove in the block head information of the effective block of at least one block checkpoint that carries carry out verifying and to it is described extremely
The corresponding accounting nodes of block height of a few block checkpoint are verified；
And/or；
The unlock proves to carry at least one block checkpoint of the second block chain；
When the first block chain verifies unlock proof, specifically include: the first block chain is to described
Unlock prove in the block head information of the effective block of at least one block checkpoint that carries carry out verifying and to it is described extremely
The corresponding accounting nodes of block height of a few block checkpoint are verified.
As a result, when transaction verification between being serviced across chain, does not need to track whole block head information, and only need to track
The corresponding accounting nodes of height of the block head information and the block head of block are verified where across chain transaction occurs.Because
Relaying is believable, then need to only determine that side chain is remembered when main chain receives the proof of the behavior comprising transaction on the side chain that relaying is submitted
Account node does not change, and exchange submits the information in proving consistent in the build information of side chain block with relaying.
Optionally, the method also includes:
When monitoring that the accounting nodes of the first block chain change, described relay is sent out to the second block chain
Change is sent to prove；
It is described to relay to the first block chain after the second block chain proves that registration is completed according to the change
Return registration proves, described to register what proof was generated for triggering the first block end of chain (EOC) by accounting nodes generation change
Transaction in assets pausing operation；
And/or；
When monitoring that the accounting nodes of the second block chain change, described relay is sent out to the first block chain
Change is sent to prove；
It is described to relay to the second block chain after the first block chain proves that registration is completed according to the change
Returning to registration proves, the registration is proved for triggering the assets that the second block end of chain (EOC) is changed by accounting nodes and is generated
Trading halt operation.
The accounting nodes alteration across chain both sides can be timely updated by above-mentioned preferred embodiment and be synchronized to other side, prevented
It only relays and does evil together with the invalid accounting nodes left one's post, guarantee the safety across chain service.
Optionally, before the first block chain locks underlying scenario, the method also includes:
The accounting nodes of second block chain described in the first block chained record；
The accounting nodes of first block chain described in the second block chained record.
Optionally, the common recognition mechanism that the first block chain and the second block chain use meets:
All accounting nodes are clear；
There are irreversible confirmation delays.
It is illustrated below by embodiment of the specific example to this specification, relaying interaction is passed through with main chain, side chain
For.
Referring to shown in Fig. 2, may include:
Step 202: when the accounting nodes for monitoring side chain change, relaying chain linked to owner sends change and proves.
At this point, the transaction in assets that the assets contract on side chain is limited enters halted state.
Step 204: main chain is registered according to change proof.
That is main chain modification information that accounting nodes on side chain are recorded on the chain of itself, to guarantee that subsequent authentication is accurate.
Step 206: relaying to side chain and return to registration proof；
Step 208: side chain is proved according to the registration of return, terminates the transaction in assets that change and generation occur by accounting nodes
Pausing operation.
In other words, across chain operation can be entered at this time.
Main chain generates mapping assets X ' to underlying scenario X again after side chain locking:
Step 210: side chain locks underlying scenario X according to across chain assets contract on side chain.
Step 212: relaying proves the behavior of the locked transaction to be submitted to main chain from side chain.
It should be understood that the behavior of the locked transaction proves, does not need the area of all blocks in this specification embodiment
Build Hash, it is only necessary to track effective accounting nodes (accounting nodes after final change, can with when be individually also possible to it is multiple
The set of accounting nodes) and across chain transaction block head Hash of block where when occurring transaction is verified, thus, simplify
Across chain operation, and the synchronization of the modification information by accounting nodes, it can be ensured that accounting nodes that both sides receive other side are
Effectively, guarantee the safety across chain service.
Step 214: main chain correspondingly generates mapping assets X '.
It maps assets X ' and unlocks underlying scenario X in side chain after main chain destruction:
Step 216: main chain destroys mapping assets X ' according to across chain assets contract on main chain.
Step 218: relaying proves the behavior that the unlock is traded to be submitted to side chain from main chain.
The effect of the step is identical with the effect of step 212, and this will not be repeated here.
Step 220: side chain correspondingly unlocks underlying scenario X.
It should be understood that scheme shown in above-mentioned Fig. 2 in fact, can also be wrapped so that the accounting nodes on side chain change as an example
It is changed containing the accounting nodes on main chain, or, there is a situation where change simultaneously for the accounting nodes on main chain and side chain.
By this specification technical solution, relaying can not forge Transaction Information, only the locking of trading activity be submitted to prove,
As long as the as full node of main chain and side chain can become the third across chain mutual concession so meet the condition of credible setting
Fang Zhongji simultaneously provides across chain service, does not need to go to generate the relaying that can be trusted by complicated means in the prior art, thus
The setting mechanism for simplifying relaying, by going the relaying trusted to simplify across chain service, and can be by the accounting nodes across chain both sides
Alteration, which timely updates, is synchronized to other side, prevents from relaying and do evil together with the invalid accounting nodes left one's post, and guarantees across chain service
Safety.In addition, it is not necessary that the block head Hash of all blocks, it is only necessary to track (the final change of effective accounting nodes
Accounting nodes afterwards, can with when be individually also possible to the set of multiple accounting nodes) and across chain transaction occur when where block
Block head Hash transaction is verified, thus, simplify across chain operation, promote across chain efficiency on the whole.
