Horizon
Horizon is the client facing API server for the Stellar ecosystem. It acts as the interface between stellar-core and applications that want to access the Stellar network. It allows you to submit transactions to the network, check the status of accounts, subscribe to event streams, etc. See an overview of the Stellar ecosystem for more details.
Downloading the server
Prebuilt binaries of horizon are available on the releases page.
See the old releases page for prior releases
| Platform | Binary file name |
|---|---|
| Mac OSX 64 bit | horizon-darwin-amd64 |
| Linux 64 bit | horizon-linux-amd64 |
| Windows 64 bit | horizon-windows-amd64.exe |
Alternatively, you can build the binary yourself.
Dependencies
Horizon requires go 1.9 or higher to build. See (https://golang.org/doc/install) for installation instructions.
Building
mercurial is used during glide build.
glide is used for building horizon.
Given you have a running golang installation, you can install this with:
curl https://glide.sh/get | sh
Next, you must download the source for packages that horizon depends upon. From within the project directory, run:
glide install
Then, simply run go install github.com/stellar/go/services/horizon. After successful
completion, you should find horizon is present in your $GOPATH/bin directory.
