Bystack

Official golang implementation of the Bystack protocol.

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

What is Bystack?

Bystack is software designed to operate and connect to highly scalable blockchain networks confirming to the Bystack 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 bystack is able to:

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

Installing with Homebrew

brew tap bytom/bystack && brew install bystack

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/Bytom/bystack.git $GOPATH/src/github.com/bytom/bystack

• Build source code

$ cd $GOPATH/src/github.com/bytom/bystack
$ make bystackd    # build bystackd
$ make bystackcli  # build bystackcli

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

Executables

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

Running bystack

Currently, bystack 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 bystack. This section won't cover all the commands of bystackd and bystackcli at length, for more information, please the help of every command, e.g., bystackd help.

Initialize

First of all, initialize the node:

$ cd ./cmd/bystackd
$ ./bystackd 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

$ ./bystackd node

Given the bystackd node is running, the general workflow is as follows:

• create key, then you can create account and asset.
• send transaction, i.e., build, sign and submit transaction.
• query all kinds of information, let's say, avaliable key, account, key, balances, transactions, etc.
