Tezos node/shell in Rust.

TezEdge

The purpose of this project is to implement a secure, trustworthy, open-source Tezos node in Rust. In addition to implementing a new node, the project seeks to maintain and improve the Tezos node wherever possible.

Documentation

Quick start

Pre-requisites

• GitHub repository

• Docker

1. Open shell and type this code into the command line and then press Enter

git clone https://github.com/simplestaking/tezedge
cd tezedge

2. Download and install Docker and Docker Compose

Open shell and type this code into the command line and then press Enter:

docker-compose pull
docker-compose up

3. Open the TezEdge Explorer in your browser

You can view the status of the node in your browser by entering this address into your browser's URL bar:

http://localhost:8080

Building from Source

1. Install rustup command

We recommend installing Rust through rustup.

Run the following in your terminal, then follow the onscreen instructions.

curl https://sh.rustup.rs -sSf | sh

2. Install rust toolchain

Rust nightly is required to build this project.

rustup toolchain install nightly-2020-05-15
rustup default nightly-2020-05-15

3. Install required libs

Install libs required to build sodiumoxide package:

sudo apt install pkg-config libsodium-dev

Install libs required to build RocksDB package:

sudo apt install clang libclang-dev llvm llvm-dev linux-kernel-headers libev-dev

4. Supported Linux distributions

We are linking rust code with pre-compiled Tezos shared library. For your convenience we have created pre-compiled binary files for most of the popular linux distributions:

supported linux distributions:

• Ubuntu (16.04, 18.04, 18.10, 19.04, 19.10, 20.04, 20.10)
• Debian (9, 10 )
• OpenSUSE (15.1, 15.2)
• CentOS (7, 8)

If you are missing support for your favorite linux distribution on a poll request at tezos-opam-builder project.

Running node manually

The node can built through the cargo build or cargo build --release, be aware, release build can take much longer to compile. environment variable SODIUM_USE_PKG_CONFIG=1 mus be set. Put together, node can be build, for example, like this:

SODIUM_USE_PKG_CONFIG=1 cargo build

To run node manually, path to the Tezos lib must be provided as environment variable LD_LIBRARY_PATH. It is required by protocol-runner. Put together, node can be run, for example, like this:

LD_LIBRARY_PATH=./tezos/interop/lib_tezos/artifacts cargo run --bin light-node -- --config-file ./light_node/etc/tezedge/tezedge.config

All parameters can be provided also as command line arguments in the same format as in config file, in which case they have higher priority than the ones in config file. For example we can use the default config and change the log file path:

LD_LIBRARY_PATH=./tezos/interop/lib_tezos/artifacts cargo run --bin light-node -- --config-file ./light_node/etc/tezedge/tezedge.config --log-file /tmp/logs/tezdge.log

Full description of all arguments is in the light_node README file.

Running node using run.sh script

On linux systems, we prepared convenience script to run the node. It will automatically set all necessary environmnent variables, build and run tezedge node. All arguments can be provided to the run.sh script in the same manner as described in the previous section - Running Tezedge node manually.

The following command will execute node in debug node:

./run.sh node

To run node in release mode execute the following:

./run.sh release

If you are running OSX you can use docker version:

./run.sh docker

Listening for updates. Node emits statistics on the websocket server, which can be changed by --websocket-address argument, for example:

./run.sh node --websocket-address 0.0.0.0:12345

Example of how to call the RPC

Open shell and type this code into the command line and then press Enter:

curl localhost:18732/chains/main/blocks/head

For a more detailed description of RPCs, see the shell and the protocol endpoints.
