It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
The first relay chain is a relay chain registered by a source chain in the sent cross-chain transaction, and the second relay chain is a relay chain registered by a destination chain in the cross-chain transaction. The source chain and the destination chain can be registered on a unified relay chain, and can also be registered on different relay chains.
Fig. 1 is a flowchart of a cross-chain method for blockchain transaction according to an embodiment of the present invention. As shown in fig. 1, in the present embodiment, the present invention provides a method for performing a cross-chain transaction of a blockchain transaction, including:
in a first aspect, the present invention provides a method for performing a block chain transaction across chains, where the method is applied to a first relay chain, and the method includes:
s11, receiving first cross-chain transaction request information sent by a source chain, wherein the first cross-chain transaction request information comprises transaction information of first cross-chain transaction;
s12, after verifying that the first cross-chain transaction is credible, judging whether a destination chain for receiving the cross-chain transaction is positioned on the first relay chain:
s121, if yes, the first cross-chain transaction is sent to a destination chain to complete the first cross-chain transaction;
s121' and if not, the first cross-link transaction is sent to the corresponding first cross-link gateway so that the first cross-link gateway can find the second relay link to send the first cross-link transaction to the destination link to complete the first cross-link transaction; wherein; the first cross-link gateway stores a distributed routing table of cross-link transaction, efficient cross-layer routing and transmission can be carried out on the cross-link transaction based on the distributed cross-link routing table, and a destination link is registered on the second relay link.
Specifically, taking the scenario shown in fig. 2 as an example, the first relay chain, i.e., the relay chain a, sends the first cross-chain transaction request information, where the first cross-chain transaction request information includes transaction information of the first cross-chain transaction tx1, such as the source chain ID1, the destination chain ID2, and the transaction event of the first cross-chain transaction tx 1. The relay chain A verifies whether the first cross-chain request information is credible, if not, the tx1 is rolled back, and the cross-chain is ended; if trusted, further based on transaction information of the first cross-link transaction tx1, such as whether the destination link ID2 is also registered on the relay link a:
if yes (as in fig. 2, the cross-chain transaction event is application chain 1-application chain 2), relay chain a submits first cross-chain transaction tx1 directly to the destination chain, i.e., application chain 2, and the cross-chain transaction is completed.
If not, the relay chain A sends the first cross-chain transaction tx1 to the cross-chain gateway 1 corresponding to the relay chain A, after receiving the first cross-chain transaction tx1, the cross-chain gateway 1 finds a second relay chain corresponding to a target chain, sends tx1 to the second relay chain, and sends the second relay chain first cross-chain transaction to the target chain, so that the cross-chain transaction is completed. Wherein; the cross-link gateway 1 stores a distributed routing table of cross-link transactions, that is, stores related information of relay links associated therewith, and based on the distributed cross-link routing table, efficient cross-layer routing and propagation of cross-link transactions can be performed. The second relay link has a destination chain registered thereon.
Preferably, the transaction information comprises at least one of: source link contract ID1, destination link contract ID2, cross-link transaction index, source link block number, cross-link transaction proof, custom field; the transaction information is encapsulated by IBTP (IBTP Transfer protocol) protocol. Preferably, the package structure content is as follows:
from: source chain contract ID1
To: destination link contract ID2
Index: cross-chain transaction indexing
Timestamp: source chain Block number
Payload: cross-chain call content encoding
Proof of: cross-chain transaction attestation
And (4) Extra: custom fields
CID: invoking contract ID3
Func: calling a function
Args: calling parameters of a function
Callback: callback function
Wherein, Proof: cross-chain transaction proof. The Proof field stores the legality and existence certification information of the cross-link transaction, and provides specific verification information for the relay link cross-link verification engine. The Proof field contents may vary depending on the nature of the particular application chain. The specific validation rules and modes can be dynamically loaded to the cross-chain validation engine through the flexible validation rules. Different structures are possible according to different application chains, and the main structure is determined according to the script processing of the verification rule. For example, cross-chain transaction attestation consists primarily of transaction content hashes and transaction hash signatures. The content hash is a hash of the transaction content of a cross-chain transaction, and the transaction hash signature may be, in general, a signature of the hash of the transaction content by an endorsement node in the application chain.
In further embodiments, the relay chain a may verify whether the first cross-chain request information is trusted in the following manner: after receiving the first cross-link transaction request information m1, a verification engine in the relay link A analyzes and obtains transaction information of the first cross-link transaction tx 1; the verification engine then matches the verification rules R1 recorded in the verification engine against the source chain ID1 in the obtained transaction information. Finally, the program is run according to the verification rule R1 and the obtained cross-chain transaction proof to verify whether the first cross-chain transaction tx1 conforms to the verification rule R1, and if so, the first cross-chain transaction is proved to be really from the application chain 1, i.e., the first cross-chain transaction is trusted.

FIG. 4 is a flow diagram of another preferred embodiment of the method shown in FIG. 1. As shown in fig. 4, in the present embodiment, the second relay link and the first relay link are recorded in distributed routing tables of different inter-link gateways; then the first inter-link gateway finds the second relay link to send the first inter-link transaction to the destination link to complete the first inter-link transaction:

Specifically, still taking the scenario diagram shown in fig. 2 as an example, for example, the first cross-link transaction event is an application chain 1-an application chain 4, as shown in fig. 2, a second relay chain (a relay chain C in fig. 2) where the destination chain (i.e., the application chain 4) is located and a first relay chain (a relay chain a in fig. 2) where the source chain (i.e., the application chain 1) is located are recorded in distributed routing tables of different cross-link gateways, that is, the relay chain a is recorded in the cross-link gateway 1, and the relay chain C is recorded in the cross-link gateway 2; in this case, when the cross-link gateway 1 receives the first cross-link transaction tx1 sent by the relay link a, the cross-link gateway 1 sends a request for finding the relay link C to the cross-link gateway cluster, at this time, the cross-link gateway 2 having the relay link C sends a response, the cross-link gateway 1 sends the first cross-link transaction to the cross-link gateway 2, and the cross-link gateway 2 sends the first cross-link transaction to the relay link C and finally to the application link 4, thereby completing the cross-link transaction. The cross-chain gateway cluster is composed of cross-chain gateways, and the contact and propagation of the cross-chain gateways are performed in a P2P mode through a distributed routing table.
In further embodiments, the finding, by the second gateway, the second relay chain to send the first cross-chain transaction to the destination chain to complete the first cross-chain transaction described in step S121 '1' includes:

if yes, the first cross-link transaction is sent to the destination chain to complete the first cross-link transaction;

Specifically, in order to ensure the security of the destination chain receiving transaction, the second relay node may verify the first cross-link transaction received from the second gateway, because endorsement needs to be made for the reliability and validity and authenticity of the first cross-link transaction when the first relay chain sends the first cross-link transaction, and then the second relay chain may verify whether the endorsement information made by the first relay chain is authentic or not when verifying, and if so, the transaction is considered to be authentic, and the second relay chain sends the first cross-link transaction to the destination chain to complete the cross-link transaction.
