Advanca is now Automata.

The development is moved to https://github.com/automata-network/automata. Come and join us there!

Advanca

A privacy-preserving general-purpose compute/storage infrastructure for Dapps.

Getting Started

To quickly see Advanca running, try it out with Docker Compose locally.

Note: To run the following demo successfully, make sure your machine supports SGX and have Intel SGX Linux Driver installed. If not, you can try the previous v0.2.0 version with SGX simulation mode.

git clone https://github.com/advanca/advanca.git
cd advanca
docker-compose up --no-start

Start the node and aesm first. It will run in the background.

docker-compose start node aesm

Bring up the worker. Logs will be printed.

docker-compose up worker

In a new terminal session, bring up the client.

docker-compose up client

Finally, stop and clean up.

docker-compose stop
docker-compose rm
