Methods and devices for establishing communication between blockchain networks

A device for establishing communication between a first blockchain network and a second blockchain network, comprising:

• one or more processors;
• and
• one or more computer-readable memories coupled to the one or more processors and having instructions stored thereon that are executable by the one or more processors, wherein the one or more processors are configured to:
• embed a first library into a process;
• execute the first library to create a first border node embedded into the process, wherein the first border node operates together with a first set of nodes in the first blockchain network, the first set of nodes not being embedded into the process;
• embed a second library into the process;
• execute the second library to create a second border node embedded into the process, wherein the second border node operates together with a second set of nodes in the second blockchain network, the second set of nodes not being embedded into the process;
• and
• establish a communication interface within the process to allow the first border node and the second border node to communicate with each other to jointly establish communication between the first blockchain network and the second blockchain network through the first border node and the second border node, wherein the process causes the one or more processors to allocate a trusted execution environment to the communication interface, and the first border node and the second border node communicate with each other utilizing one or more function calls.

A non-transitory computer-readable medium having stored therein instructions that, when executed by a processor of a device, cause the device to perform a method for establishing communication between a first blockchain network and a second blockchain network, the method comprising:

• embedding a first library into a process;
• executing the first library to create a first border node embedded into the process, wherein the first border node operates together with a first set of nodes in the first blockchain network, the first set of nodes not being embedded into the process;
• embedding a second library into the process;
• executing the second library to create a second border node embedded into the process, wherein the second border node operates together with a second set of nodes in the second blockchain network, the second set of nodes not being embedded into the process;
• and
• establishing a communication interface within the process to allow the first border node and the second border node to communicate with each other to jointly establish communication between the first blockchain network and the second blockchain network through the first border node and the second border node, wherein the process causes the processor to allocate a trusted execution environment to the communication interface, and the first border node and the second border node communicate with each other utilizing one or more function calls.
