Vapor

Build Status AGPL v3

Golang implemented sidechain for Bytom.

Requirements

  • Go version 1.11 or higher, with $GOPATH set to your preferred directory

Get source code

$ cd $GOPATH/src/github.com/bytom
$ git clone https://github.com/Bytom/vapor.git

Then, you have two ways to get vapor executable file:

  1. compile source code
  2. build it using Docker

Installation

$ cd $GOPATH/src/github.com/bytom/vapor
$ make install

Run Directly

Firstly, you need initialize node:

$ vapord init --chain_id=mainnet --home <vapor-data-path>

The default vapor data path (on the host) is:

  • Mac: ~/Library/Application Support/Vapor
  • Linux: ~/.vapor
  • Windows: %APPDATA%\Vapor

Then, start your node:

$ vapord node --home <vapor-data-path>

Running in Docker

Build the image
$ cd $GOPATH/src/github.com/bytom/vapor
$ docker build -t vapor .
Enter the iterative mode
$ docker run -it --net=host -v <vapor/data/directory/on/host/machine>:/root/.vapor vapor:latest

vapor data directory has three config files:

  • config.toml
  • federation.json
  • node_key.txt

Use exit to exit Docker's iterative mode.

Daemon mode

For example,

$ docker run -d --net=host -v <vapor/data/directory/on/host/machine>:/root/.vapor vapor:latest vapord node --web.closed --auth.disable

To list the running containners and check their container id, image, corresponding command, created time, status, name and ports being used:

$ docker container ls

or

$ docker ps

To execute a command inside a containner, for example:

$ docker exec -it <containerId> vaporcli create-access-token <tokenId>

To stop a running containner:

$ docker stop <containerId>

To remove a containner:

$ docker rm <containerId>
Reward distribution tool

After the supernode and alternative node receive the reward from the node, they will allocate the reward

according to the interest rate.

The reward calculation rules:

calculate the reward (consensus reward * interest rate * voting weight) according to the weight of votes

cast in consensus around, and choose how many rounds of consensus to allocate the reward flexibly.

Tool usage details

Merger utxo

UTXO has been merged to solve the problem that too much UTXO input causes a failed send transaction to fail. details
