NeoCompiler Eco 3+

This is an open-source initiative for providing an easy access to on NEO ecosystem.

In particular, we provide simple interact and didactic interfaces for allowing online compiling for C#, Python, Go and Java.

Official Documentation on ReadTheDocs

Documentation Status

Building Sphinx Documentation Locally

Just type ./make-docs.sh, and find ./docs/build/html/index.html (the same as ReadTheDocs)

Suggestions

Browsers/Devices

  • Tested with Firefox Quantum - 84.0
The current front-end interface can be acessed from:
Compilers RPC API services are available at:
Other useful services

What does it currently do

  • Compile input C# code using reliable and safe servers (backend) compilers;
  • Return NEF compatible files: AVM, ABI and MANIFEST codes;
  • Deploy and invoke code to private net, shared privatenet, testnet (unsafe), mainet (unsafe);
  • Save your history of activies for testing a given smart contract;
  • Tests with different wallets, synced and with able to provide historic data our activity;
  • Perform all up-to-date blockchain invocations and RPC calls;
  • Runs RPC with all enabled plugins and up-to-date features;
  • Provide basic statistical data;
  • Use websockets to provide some useful information;
  • It can be used on TestNet, or even MainNet.

Roadmap

  • Move towards client-based compiling (more secure, robust and much more scalable).
  • Ideas? Collaborations are welcome :) The goal is to be didactic and bring it close to citizens and users: Smart Cities, Smart Governance and Smart Blockchain Technologies :P

Dependencies

Installing docker-compose 1.19.0+

We need docker-compose version 1.23.1 (or more), so we recommend the following steps for installation:

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

echo "export PATH=\$PATH:/usr/local/bin/" >> ~/.bashrc

source ~/.bashrc

Docker recommendations

Docker technology is essential for sandboxing all compilers in different environments (for different languages).

sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo apt-key fingerprint 0EBFCD88

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt update

sudo apt-get install docker-ce docker-ce-cli containerd.io

If necessary, add user to docker group: sudo usermod -a -G docker $USER

Build everything

The online command required to create our own NeoCompiler Ecosystem, suitable for private of public blockchain projects.

This will call a docker-compose with NeoCompiler Private Net (Eco) + NeoScan (optional). Furthermore, it will set all available compilers and open the front/backend interface and server, respectively.

./build_everything.sh

Developers guidelines

Basically, two steps are required: A1 and A2. Both are described below.

A1) Building compilers

This script already builds the compilers and starts the server:

./docker-sock-express-compilers/docker-compilers/buildCompilers.sh

  • Edit ./docker-sock-express-compilers/docker-compilers/.env if you want to build other compilers, for example BUILD_ALL_CSHARP=0
    • Build list with different versions for a given compiler, such as: docker-sock-express-compilers/docker-compilers/compilers/docker-compiler-csharp/docker_build_list_of_compilers.sh

Building C# Neo Core Compiler entrypoint based image

The backend for C# is provided using native github/neo-project tools, only two steps are necessary to build and tag image:

cd /docker-sock-express-compilers/docker-compilers/compilers/docker-compiler-csharp

docker_build.sh

Running express node servers

Base images express nodes and dockers

docker-sock-express-compilers/docker-ubuntu-docker-node-express

./docker_build-all.sh will build both:

  • essential docker image for express and node docker_build-express.sh
  • the aforementioned image with docker docker_build-express-docker.sh

Http front-end: cd /docker-sock-express-compilers/docker-http-express

docker-compose up

Compilers RPC API Backend: cd docker-sock-express-compilers/docker-compilers

docker-compose up

Eco Services: cd docker-sock-express-compilers/docker-services

docker-compose up

A2) Eco Network Funtionalities

Docker-compose is the main tools that acts for the creation of our micro-service. This script will start all necessary backend functionalities and neo-csharp-nodes.

In particular, we currently have:

  • csharp nodes are with TCP at 2033x and RPC at 3033X, websocket is not being used
    • 4 csharp consensus node, two of them are also a RPC as default at port 30333 and 30334;
    • 1 csharp pure RPC nodes at 30337;

Dealing with docker-compose swarm of containers

Start up the container, checking the messages and following warnings

Simply run runEco_network.sh (integrated with .env file)

or:

cd ./docker-compose-eco-network

docker-compose up

Start up the container in a detached mode

docker-compose up -d

Feel free to take is down

docker-compose down

However, consider stopping and restarting

docker-compose stop
docker-compose start

NeoCompiler Eco useful commands and ideas

Other functionalities and integrations are possible and some are implemented

It is also possible to integrate the Eco Network with lighwallet and explorers.

Other parameters

One could check docker docker-compose.yml, picking up a combination of your choice from docker-compose-eco-network folder. This can be done for locally modifying some characteristics.

Run build_everything.sh with an additional parameter --no-build and your modified node zip of the private net will be called, use the name neo-cli-built.zip.

Useful Commands

open csharpnodes

  • docker exec -it eco-neo-csharp-node1-running bash
  • screen -dr will show the screen
  • /opt/run.sh will start a new screen (if you killed the last process);
  • /opt/start_node.sh will start the node directly in the terminal.

Contributing

  • If you have ideas or issues, you can inform directly at github or contact us directly

    1. Check the open issues and pull requests for existing discussions.
    2. Open an issue first, to discuss a new feature or enhancement.
    3. Write tests, and make sure the test suite passes locally and on CI.
    4. Open a pull request, and reference the relevant issue(s).
    5. After receiving feedback, squash your commits and add a great commit message.
    6. Run make push-tag after merging your pull request.
    7. Anyway, you already were part of team... :P
  • Our team is currently formed by researchers/professors, so our time is very constrained... if you feel you can help us, don't hesitate!

  • We created a wallet specially for project donations. That can help us improve our servers and perhaps hire someone for improving graphical interfaces and developing many more interesting features. NEO wallet: AJX1jGfj3qPBbpAKjY527nPbnrnvSx9nCg
