janeta

Build Status AGPL v3

Official golang implementation of the janeta protocol.

Automated builds are available for stable releases and the unstable master branch. Binary archives are published at https://github.com/janotchain/janeta/releases.

What is janeta?

janeta is software designed to operate and connect to highly scalable blockchain networks confirming to the janeta Blockchain Protocol, which allows partipicants to define, issue and transfer digitial assets on a multi-asset shared ledger. Please refer to the White Paper for more details.

In the current state janeta is able to:

  • Manage key, account as well as asset
  • Send transactions, i.e., issue, spend and retire asset

Installing with Homebrew

brew tap janeta/janeta && brew install janeta

Building from source

Requirements

  • Go version 1.8 or higher, with $GOPATH set to your preferred directory

Installation

Ensure Go with the supported version is installed properly:

$ go version
$ go env GOROOT GOPATH
  • Get the source code
$ git clone https://github.com/janotchain/janeta.git $GOPATH/src/github.com/janotchain/janeta
  • Build source code
$ cd $GOPATH/src/github.com/janotchain/janeta
$ make janetad    # build janetad
$ make janetacli  # build janetacli

When successfully building the project, the janetad and janetacli binary should be present in cmd/janetad and cmd/janetacli directory, respectively.

Executables

The janeta project comes with several executables found in the cmd directory.

Command Description
janetad janetad command can help to initialize and launch janeta domain by custom parameters. janetad --help for command line options.
janetacli Our main janeta CLI client. It is the entry point into the janeta network (main-, test- or private net), capable of running as a full node archive node (retaining all historical state). It can be used by other processes as a gateway into the janeta network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. janetacli --help and the janetacli Wiki page for command line options.

Running janeta

Currently, janeta is still in active development and a ton of work needs to be done, but we also provide the following content for these eager to do something with janeta. This section won't cover all the commands of janetad and janetacli at length, for more information, please the help of every command, e.g., janetacli help.

Initialize

First of all, initialize the node:

$ cd ./cmd/janetad
$ ./janetad init --chain_id mainnet

There are three options for the flag --chain_id:

  • mainnet: connect to the mainnet.
  • testnet: connect to the testnet wisdom.
  • solonet: standalone mode.

After that, you'll see config.toml generated, then launch the node.

launch

$ ./janetad node
