Description
Technical field
The present invention relates to a kind of across the chain method of block chain, more particularly to one kind carried out between multi-tiling chain network data across
The method of chain interaction.
Background technique
Block chain is substantially a kind of distributed, multicenter chain type account book database, but in block chain ecology
In system, the presence of more and more block chain networks produces more and more " data silo ".Across the chain technology of block chain is exactly
In order to solve the problems, such as data transmitting, transfer, exchange between two or more different blocks chain networks.Data not only can be with across chain
Increase the expansibility of block chain network, while the cost of data sharing between block chain network can also be reduced.
But across the chain technology of block chain is still within developing stage at present, small, resource utilization that there is also across chain handling capacities
The numerous disadvantages of low and response time slowly.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, a kind of method the present invention provides block chain across chain and realization system
System.
Method and realization system the present invention provides a kind of block chain across chain, include the following steps.
S1, local main chain in block chain network is established, for recording the uplink data information of this area block chain.
S2, establish it is local between long-range block chain network across chain link, for local between long-range block chain network
Do data interaction on chain.
S3, local cache logic chain is established, for the interaction data in long-range block chain network to be cached to local logic
It is called in chain for Distributed Application.
The local main chain in block chain network is established in the step S1, the uplink data for recording this area block chain is believed
Breath, specifically includes following steps.
S11: a channel is established in local block chain network by the way of logic chain.
S12: the channel established S11 is denoted as local main chain, for recording the uplink data information of this area block chain.
Established in the step S2 it is local between long-range block chain network across chain link, for local with long-range block chain
Data interaction on chain is done between network, specifically includes following steps.
Preferably, it S21: is done by the way of RestAPI across chain between local block chain network and long-range block chain network
Data interaction, both sides respectively establish across chain connector (Cross Chain Connector, CCC), and centre carries out net by VPN
Network connection.
Optionally, across chain data interaction is done by way of RPC, is connected to the network by special line.
S22: local block chain network by S21 establish across chain connector by main chain in long-range block chain network share
Block chain data are fetched by the way of with the increment query for saving point.
S23: the main chain data buffer storage shared in the long-range block chain network that local block chain network fetches S22 to local
In the logic chain of block chain network.
S24: local block chain network is responsible for the data on the chain of Distributed Application summary request.
Local cache logic chain is established in the step S3, for the interaction data in long-range block chain network to be cached to
It is called in local logic chain for Distributed Application, specifically includes following steps.
S31: local cache logic chain is established respectively between across the chain object of block chain network.
S32: by the data in the long-range block chain data fetched in S22 step and local cache logic chain, local main chain
Distributed application program is returned to after taking union.
The cache module of the local logic chain is and to be buffered in local patrol by across chain connector acquisition data
It collects in chain, convenient for later inquiry, while reducing data volume interactive every time.
The present invention has the following advantages and beneficial effects: method and realization system the present invention provides a kind of block chain across chain
System, this across chain method can not only do across chain data interaction while have the caching function of block chain data, can complete area
Between block chain network while data interconnection intercommunication, throughput of system, resource utilization and system of the block chain across chain query are improved
Response time.
