Official golang implementation of the Bytom protocol.
Automated builds are available for stable releases and the unstable master branch. Binary archives are published at https://github.com/Bytom/bytom/releases.
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
Installing with Homebrew
brew tap bytom/bytom && brew install bytom
Building from source
- Go version 1.8 or higher, with
$GOPATHset to your preferred directory
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/bytom.git $GOPATH/src/github.com/bytom/bytom
- Build source code
$ cd $GOPATH/src/github.com/bytom/bytom $ make bytomd # build bytomd $ make bytomcli # build bytomcli
When successfully building the project, the
bytomcli binary should be present in
cmd/bytomcli directory, respectively.
The Bytom project comes with several executables found in the
|bytomd||bytomd command can help to initialize and launch bytom domain by custom parameters.
|bytomcli||Our main Bytom CLI client. It is the entry point into the Bytom 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 Bytom network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports.
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
bytomcli at length, for more information, please the help of every command, e.g.,
First of all, initialize the node:
$ cd ./cmd/bytomd $ ./bytomd init --chain_id mainnet
There are three options for the flag
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.
$ ./bytomd node
available flags for

Use --home (default "/Users/zcc/Library/Application Support/Bytom") --trace print out full stack trace on errors
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.
You could enable the simd feature to speed up the PoW verification (e.g., during mining and block verification) by simply:
bytomd node --simd.enable
To enable this feature you will need to compile from the source code by yourself, and
What is more,
- if you are using Mac, please make sure llvm is installed by
brew install llvm.
- if you are using Windows, please make sure mingw-w64 is installed and set up the PATH environment variable accordingly.
