Golang implemented sidechain for Bytom.
What is Vapor?
Vapor is software designed to extensions to the Bytom protocol, which allows partipicants to define, issue and transfer digitial assets on a multi-asset shared ledger or networks pegged to Bytom as a sidechain or run as a standalone blockchain.
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/vapor.git $GOPATH/src/github.com/vapor
- Build source code
$ cd $GOPATH/src/github.com/vapor $ make vapor # build vapor $ make vaporcli # build vaporcli
When successfully building the project, the
vaporcli binary should be present in
cmd/vaporcli directory, respectively.
The Vapor project comes with several executables found in the
|vapor||vapor command can help to initialize and launch vapor domain by custom parameters.
|vaporcli||Our main Vapor CLI client. It is the entry point into the Vapor 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 Vapor network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports.
Currently, vapor 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
vapor. This section won't cover all the commands of
vaporcli at length, for more information, please the help of every command, e.g.,
First of all, initialize the node:
$ cd ./cmd/vapor $ ./vapor 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.
$ ./vapor node

vapor node is running, the general workflow is as follows:
- create key, then you can create account.
- send transaction, i.e., build, sign and submit transaction.
- query all kinds of information, let's say, avaliable key, account, key, balances, transactions, etc.
