Installation

Requirements

Thor requires Go 1.10+ and C compiler to build. To install Go, follow this link.

Getting the source

Clone the Thor repo:

git clone https://github.com/vechain/thor.git
cd thor

Dependency management

Simply run:

make dep

To manually install dependencies, choices are

• dep, Golang's official dependency management tool

  dep ensure -vendor-only
  

  (Note that to make dep work, you should put the source code at $GOPATH/src/github.com/vechain/thor)

• git submodule

  git submodule update --init
  

Building

To build the main app thor, just run

make

or build the full suite:

make all

If no error reported, all built executable binaries will appear in folder bin.

Running Thor

Connect to VeChain's mainnet:

bin/thor --network main

Connect to VeChain's testnet:

bin/thor --network test

To find out usages of all command line options:

bin/thor -h

• --network value the network to join (main|test)
• --data-dir value directory for block-chain databases
• --beneficiary value address for block rewards
• --api-addr value API service listening address (default: "localhost:8669")
• --api-cors value comma separated list of domains from which to accept cross origin requests to API
• --verbosity value log verbosity (0-9) (default: 3)
• --max-peers value maximum number of P2P network peers (P2P network disabled if set to 0) (default: 25)
• --p2p-port value P2P network listening port (default: 11235)
• --nat value port mapping mechanism (any|none|upnp|pmp|extip:) (default: "none")
• --help, -h show help
• --version, -v print the version

Sub-commands

• solo client runs in solo mode for test & dev

bin/thor solo --on-demand               # create new block when there is pending transaction
bin/thor solo --persist                 # save blockchain data to disk(default to memory)
bin/thor solo --persist --on-demand     # two options can work together

• master-key import and export master key

# export master key to keystore
bin/thor master-key --export > keystore.json


# import master key from keystore
cat keystore.json | bin/thor master-key --import

Docker

Docker is one quick way for running a vechain node:

docker run -d\
  -v {path-to-your-data-directory}/.org.vechain.thor:/root/.org.vechain.thor\
  -p 127.0.0.1:8669:8669 -p 11235:11235 -p 11235:11235/udp\
  --name thor-node vechain/thor --network test

Do not forget to add the --api-addr 0.0.0.0:8669 flag if you want other containers and/or hosts to have access to the RESTful API. Thorbinds to localhost by default and it will not accept requests outside the container itself without the flag.

The Dockerfile is designed to build the last release of the source code and will publish docker images to dockerhub by release, feel free to fork and build Dockerfile for your own purpose.

Explorers

Awesome explorers built by the community:

• VeScan
• VeForge by Totient Labs
• TheVechain

Testnet faucet

curl -X POST -d '{"to":"Your_Address"}' -H "Content-Type: application/json" https://faucet.outofgas.io/requests

API

Once thor started, online OpenAPI doc can be accessed in your browser. e.g. http://localhost:8669/ by default.

Acknowledgement

A Special shout out to following projects:

• Ethereum

• Swagger

Contributing

Thanks you so much for considering to help out with the source code! We welcome contributions from anyone on the internet, and are grateful for even the smallest of fixes!

Please fork, fix, commit and send a pull request for the maintainers to review and merge into the main code base.

Forking Thor

When you "Fork" the project, GitHub will make a copy of the project that is entirely yours; it lives in your namespace, and you can push to it.

Getting ready for a pull request

Please check the following:

• Code must be adhere to the official Go Formatting guidelines.
• Get the branch up to date, by merging in any recent changes from the master branch.

Making the pull request

• On the GitHub site, go to "Code". Then click the green "Compare and Review" button. Your branch is probably in the "Example Comparisons" list, so click on it. If not, select it for the "compare" branch.
• Make sure you are comparing your new branch to master. It probably won't be, since the front page is the latest release branch, rather than master now. So click the base branch and change it to master.
• Press Create Pull Request button.
• Give a brief title.
• Explain the major changes you are asking to be code reviewed. Often it is useful to open a second tab in your browser where you can look through the diff yourself to remind yourself of all the changes you have made.
