6 **Official golang implementation of the Bytom protocol.**
8 Automated builds are available for stable releases and the unstable master branch. Binary archives are published at https://github.com/Bytom/bytom/releases.
12 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](https://github.com/Bytom/wiki/blob/master/White-Paper/%E6%AF%94%E5%8E%9F%E9%93%BE%E6%8A%80%E6%9C%AF%E7%99%BD%E7%9A%AE%E4%B9%A6-%E8%8B%B1%E6%96%87%E7%89%88.md) for more details.
14 In the current state `bytom` is able to:
16 - Manage key, account as well as asset
17 - Send transactions, i.e., issue, spend and retire asset
20 ## Building from source
24 - [Go](https://golang.org/doc/install) version 1.8 or higher, with `$GOPATH` set to your preferred directory
28 Ensure Go with the supported version is installed properly:
32 $ go env GOROOT GOPATH
38 $ git clone https://github.com/Bytom/bytom.git $GOPATH/src/github.com/bytom
44 $ cd $GOPATH/src/github.com/bytom
45 $ make bytomd # build bytomd
46 $ make bytomcli # build bytomcli
49 When successfully building the project, the `bytom` and `bytomcli` binary should be present in `cmd/bytomd` and `cmd/bytomcli` directory, respectively.
53 The Bytom project comes with several executables found in the `cmd` directory.
55 | Command | Description |
56 | ------------ | ------------------------------------------------------------ |
57 | **bytomd** | bytomd command can help to initialize and launch bytom domain by custom parameters. `bytomd --help` for command line options. |
58 | **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. `bytomcli --help` and the [bytomcli Wiki page](https://github.com/Bytom/bytom/wiki/Command-Line-Options) for command line options. |
62 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`.
66 First of all, initialize the node:
70 $ ./bytomd init --chain_id mainnet
73 There are three options for the flag `--chain_id`:
75 - `mainnet`: connect to the mainnet.
76 - `testnet`: connect to the testnet wisdom.
77 - `solonet`: standalone mode.
79 After that, you'll see `config.toml` generated, then launch the node.
87 available flags for `bytomd node`:
90 --auth.disable Disable rpc access authenticate
91 --chain_id string Select network type
92 -h, --help help for node
93 --mining Enable mining
94 --p2p.dial_timeout int Set dial timeout (default 3)
95 --p2p.handshake_timeout int Set handshake timeout (default 30)
96 --p2p.laddr string Node listen address.
97 --p2p.max_num_peers int Set max num peers (default 50)
98 --p2p.pex Enable Peer-Exchange (default true)
99 --p2p.seeds string Comma delimited host:port seed nodes
100 --p2p.skip_upnp Skip UPNP configuration
101 --prof_laddr string Use http to profile bytomd programs
102 --vault_mode Run in the offline enviroment
103 --wallet.disable Disable wallet
104 --wallet.rescan Rescan wallet
105 --web.closed Lanch web browser or not
106 --simd.enable Enable the _simd_ feature to speed up the _PoW_ verification (e.g., during mining and block verification)
109 Given the `bytomd` node is running, the general workflow is as follows:
111 - create key, then you can create account and asset.
112 - send transaction, i.e., build, sign and submit transaction.
113 - query all kinds of information, let's say, avaliable key, account, key, balances, transactions, etc.
117 You could enable the _simd_ feature to speed up the _PoW_ verification (e.g., during mining and block verification) by simply:
119 bytomd node --simd.enable
122 To enable this feature you will need to compile from the source code by yourself, and `make bytomd-simd`.
126 + if you are using _Mac_, please make sure _llvm_ is installed by `brew install llvm`.
127 + if you are using _Windows_, please make sure _mingw-w64_ is installed and set up the _PATH_ environment variable accordingly.
129 For more details about using `bytomcli` command please refer to [API Reference](https://github.com/Bytom/bytom/wiki/API-Reference)
