Lightwallet server for Zcash

Collaborated heavily with Boltlabs

Build a zcashd node from multi-container Docker build

cd ./Dockerfiles/zcashd
bash build-image.sh

Create docker volumes and populate the zcash-params volume

See example scripts create_mainnet_params_volume.sh. Change accordingly for testnet.

Build a monolith container with lightwallet node and zcashd node from multi-container Docker build

cd ./Dockerfiles/lightwalletd
bash build-image.sh

Fetch params into a volume:

docker run --rm -itd \
--user zcash \
--mount source=testnet-params,destination=/home/zcash/.zcash-params \
zcash-hackworks/lightwalletd:latest bash -c "fetch-params.sh"

To follow progress run:

docker logs -f `docker ps | grep lightwalletd | cut -d' ' -f1`

Run the container. Make sure you have whatever firewall open on port 9067.

bash Dockerfiles/lightwalletd/run_zcashd_container.sh

Check that it is running

Fetch docker-grpcurl

curl -LO https://raw.githubusercontent.com/datawire/docker-grpcurl/master/grpcurl.sh && chmod +x grpcurl.sh

(I had to remove the 'set' in that script for it to run)

Check the API is up. It will return the latest block indexed into lightwallet db.

./grpcurl.sh -plaintext localhost:9067 cash.z.wallet.sdk.rpc.CompactTxStreamer/GetLatestBlock
{
  "height": ${SOME_INTEGER_HEIGHT}
}

ToDo

1. TLS termination via load balancer or through gRPC library.
2. Finish and clean up docker-compose.yml stack deploy.
