Below in conjunction with attached drawing, the present invention will be described in detail.
Fig. 1 is flow chart 100 of the realization across the method for chain transactional operation of embodiment according to the present invention.
Step S101: the account information of sender and recipient in transaction are obtained, wherein the account information includes sending
The address information of the account of side and recipient.
Step S102: parameter transaction is determined based on acquired account information, wherein the parameter transaction includes resource
Consumption and intelligent contract method parameter in execution.
Step S103: based on determining parameter transaction, in the connection protocol and its link address information aggregate of multiple public chains
The connection protocol and its link address information of middle determining target public affairs chain.
Step S104: corresponding mesh is connected to by the connection protocol and its link address information of identified target public affairs chain
Mark public chain.
Fig. 2 is the flow chart 200 of the method according to an embodiment of the invention for realizing across chain money transfer transactions operation.
By taking the money transfer transactions of ether mill as an example, realize that money transfer transactions operation is needed by following steps:
The interface of transferring accounts for ether mill that step S201:Dapp calls the SDK (Software Development Kit) of building to provide,
It should be understood that including the address information in multiple interfaces and interface including the target public affairs chain to be connected, example in the SDK of building
Such as, for ether mill realization money transfer transactions the interface A that transfers accounts, for the query interface B etc. of the realization inquiry in ether mill.
Step S202:SDK obtains the address information of transaction sender and recipient and the private key of sender from Dapp.
Step S203:SDK determines parameter transaction based on the address information of acquired sender.Parameter transaction includes example
Such as nonce (counting), toAddr (sending address), amount (quantity), gasLimit (resource consumption), gasPrice (resource
Price), payload (payload) etc..It should be understood that the parameter transaction that different target public affairs chains requires is different, part is handed over
Easy parameter needs self-setting and carries out assignment conversion, and part parameter transaction needs to obtain from target public affairs chain, when sending transaction
When information, these parameter transactions are enclosed, the parameter transaction that same target public affairs chain is related to is substantially identical, and only value is different.
Step S204:SDK creates transaction based on determining parameter transaction, is signed and sent transaction letter so as to subsequent
Breath.
Step S205:SDK signs to Transaction Information using the private key of sender, to guarantee the transaction really by sending
It initiates in person side.Herein, Transaction Information refers to the record of completed transaction, for example, account A transfers accounts 200 pieces to account B
Record.
Step S206:SDK is connected to ether by the ether mill connection protocol and its link address information for including in itself
The respective nodes in mill.It should be understood that including multiple public connection protocols of chain and its set of link address information in SDK, make
Obtaining SDK may be coupled to multiple target public affairs chains, first determine the connection protocol of target public affairs chain before linking objective public affairs chain in the set
And its link address information.
Step S207:SDK initiates transaction request.
Step S208: the node in ether mill carries out sign test to the Transaction Information received by the public key of sender, with
The authenticity and correctness for verifying the transaction, to reach common understanding.
Step S209: the node in ether mill is packaged Transaction Information and records Transaction Information, is reached common understanding by digging mine, area
All nodes in block chain network can all record Transaction Information.
The SDK of building provided by the invention can be passed to parameter by interface by providing multiple interfaces, dapp, thus logical
It crosses SDK to be connected to respective objects block chain and carry out it corresponding transactional operation, and some steps in SDK as needed
It can be adjusted.
Fig. 3 shows the realization of embodiment according to the present invention across the schematic diagram of the device 300 of chain transactional operation.
