Described herein are systems and methods for implementing a distributed ledger a blockchain cloud service. The blockchain cloud service can include nodes of the distributed ledger and a REST proxy service component. The REST proxy service uses a service development kit for the distributed ledger to communicate with the distributed ledger, and can provide REST APIs for use by client applications to query through chaincodes, synchronously or asynchronously invoke transactions through the chaincodes, get transaction statuses, and get BCS proxy versions. The REST proxy service component can authenticate REST calls, and translate the REST calls into remote procedural calls, for use in interfacing with the distributed ledger. The REST proxy service component can further provide REST APIs that support the same functions which are provided by the BCS management console component, and provide a user interface for client applications to consume the BCS instance.

System and method for providing a representational state transfer proxy service for a blockchain cloud service

A radio frequency power amplifier and a device are disclosed. A first microstrip line and a second microstrip line are coupled, one end of the second microstrip line is an open stub and another end of the second microstrip line is grounded; and the first microstrip line having a first width is connected to a first transmission line having a second width which is wider than the first width. Therefore, some harmonic bands suppression can be implemented independently. Furthermore, the harmonic termination is independent and may not impact one or more fundamental components during matching a network. In addition, it may not take up more space and is sufficiently compact. Furthermore, sufficient wide harmonic response bandwidth can be provided.

Radio frequency power amplifier and device

In accordance with an embodiment, described herein is a system and method for implementing a distributed ledger a blockchain cloud service. The blockchain cloud service can include nodes of the distributed ledger and a management console component. The management console component can include a web application running in a script runtime environment, a plurality of backend of APIs for communicating with various nodes of the blockchain cloud service, and a plurality of client APIs configured to be invoked by a client application. The plurality of client APIs uses one or more of the plurality of backend APIs in provisioning the distributed ledger as a blockchain cloud service, and in managing the managing the blockchain cloud service.
