C++ Application#

The repository contains a C++ implementation of a simple example application for logging. These are meant to serve as templates for building more useful applications and to showcase core features.

Note

The following description is out-of-date. Logging will be extended to demonstrate more features, and this document should be updated in-sync.

The Logging application implements a trivial protocol, made up of four transaction types:

  • POST /app/log/private, which writes a private log message at a given index. Note that the log message will be encrypted on the ledger and only readable by nodes on the network.

    Log a private message:

    {
    "id": 42,
    "msg": "A sample private log message"
}

  • GET /app/log/private, which retrieves a private log message from a given index written by a previous POST /app/log/private call.

    Get a private message:

    {
    "id": 42
}

  • POST /app/log/public, which writes a public log message at a given index. Note that the log message will be not be encrypted and thus to anyone with access to the ledger.

    Log a public message:

    {
    "id": 100,
    "msg": "A sample public log message"
}

  • GET /app/log/public, which retrieves a public log from a given index written by a previous POST /app/log/public call.

    Get a public message:

    {
    "id": 100
}

The C++ implementation of the Logging application is located in the samples/apps/logging/ folder. It is discussed in detail on the following pages:
