Bytom

What is Bytom?

Bytom is software designed to operate and connect to highly scalable blockchain networks confirming to the Bytom 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 bytom is able to:

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

Build 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/HonaYZ/Bytom1.0.1.git $GOPATH/src/github.com/bytom

Build

$ cd $GOPATH/src/github.com/bytom
$ make bytomd    # build bytomd
$ make bytomcli  # build bytomcli

When successfully building the project, the bytom and bytomcli binary should be present in cmd/bytomd and cmd/bytomcli directory, respectively.

Example

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

Initialize

First of all, initialize the node:

$ cd ./cmd/bytomd
$ ./bytomd init --chain_id testnet

There are two options for the flag --chain_id:

testnet: connect to the testnet.
mainnet: standalone mode.

After that, you'll see .bytomd generated in current directory, then launch the node.

launch

$ ./bytomd node --mining

available flags for bytomd node:

      --auth.disable                Disable rpc access authenticate
      --mining                      Enable mining
      --p2p.dial_timeout int        Set dial timeout (default 3)
      --p2p.handshake_timeout int   Set handshake timeout (default 30)
      --p2p.laddr string            Node listen address.
      --p2p.max_num_peers int       Set max num peers (default 50)
      --p2p.pex                     Enable Peer-Exchange
      --p2p.seeds string            Comma delimited host:port seed nodes
      --p2p.skip_upnp               Skip UPNP configuration
      --prof_laddr string           Use http to profile bytomd programs
      --wallet.disable              Disable wallet
      --web.closed                  Lanch web browser or not

Given the bytomd 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.

Dashboard

Access the dashboard:

$ open http://localhost:9888/

Create key

You can create a key with the following command:

$ ./bytomcli create-key alice 123
{
  "alias": "alice",
  "xpub": "d91df216da6c5641ef454c8da1e56362f86ed80d8b8fc26ab77746e1b92d6d3aa8023fe300e4c74036460d01349e4eb25cb3d7379bad855879017bc1c76165bb"
}

list the keys:

$ ./bytomcli list-keys

Create account

Create an account named alice:

$ ./bytomcli create-account alice d91df216da6c5641ef454c8da1e56362f86ed80d8b8fc26ab77746e1b92d6d3aa8023fe300e4c74036460d01349e4eb25cb3d7379bad855879017bc1c76165bb

Sending transaction

Every asset-related action is trigger via sending a transaction, which requires two steps to complete, i.e., build-transaction and sign-submit-transaction. Don't forget to enable --mining.

Issue

build-transaction

Let's say, issue 10000 GOLD to alice:

$ ./bytomcli create-account-receiver alice

Spend

Alice pays Bob <payment_amount>, e.g., 1000, GOLD:

create-account-receiver

Before you transfer an asset to another account, you have to know his control_program. This means the receiver needs to send you his control_program first.

$ ./bytomcli create-account-receiver bob
