MobyMask
The MobyMask watcher is a Laconic Network component that provides efficient access to MobyMask contract data from Ethereum, along with evidence allowing users to verify the correctness of that data. The watcher source code is available in this repository and a developer-oriented Docker Compose setup for the watcher can be found here. The watcher can be deployed automatically using the Laconic Stack Orchestrator tool as detailed below:
Deploy the MobyMask Watcher
The instructions below show how to deploy a MobyMask watcher using laconic-stack-orchestrator (the installation of which is covered here).
This deployment expects that ipld-eth-server's endpoints are available on the local machine at http://ipld-eth-server.example.com:8083/graphql and http://ipld-eth-server.example.com:8082. More advanced configurations are supported by modifying the watcher's config file.
Clone required repositories
$ laconic-so setup-repositories --include cerc-io/watcher-ts
Build the watcher container
$ laconic-so build-containers --include cerc/watcher-mobymask
This should create a container with tag cerc/watcher-mobymask in the local image registry.
Deploy the stack
First the watcher database has to be initialized. Start only the mobymask-watcher-db service:
$ laconic-so deploy-system --include watcher-mobymask up mobymask-watcher-db
Next find the container's id using docker ps then run the following command to initialize the database:
$ docker exec -i <mobymask-watcher-db-container> psql -U vdbm mobymask-watcher < config/watcher-mobymask/mobymask-watcher-db.sql
Finally start the remaining containers:
$ laconic-so deploy-system --include watcher-mobymask up
Correct operation should be verified by following the instructions here, checking GraphQL queries return valid results in the watcher's playground.
Clean up
Stop all the services running in background:
$ laconic-so deploy-system --include watcher-mobymask down
