Dependencies

• Rust
  • Mac, Linux installation: $ curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
• Solana
  • Mac, Linux installation: $ sh -c "$(curl -sSfL https://release.solana.com/latest/install)")
• Node.js
• Anchor
  1. prebuild (only Linux): $ npm i -g @project-serum/anchor-cli
  2. build from source: cargo install --git https://github.com/project-serum/anchor --tag v0.20.1 anchor-cli --locked

Deploy

• run anchor deploy from the comm directory to deploy to devnet. Alternativly use the Solana CLI:
  • solana config set --keypair wallets/admin-keypair.json
  • solana config set --url devnet
  • solana program deploy --program-id target/deploy/comm-keypair.json target/deploy/comm.so
• the sensor wallet must have some funding to work: solana airdrop 2 will give us 2 SOL to work with. This is the limit for devnet and you may need to execute it several times to get enough funding for deployment.

Run

clients need environment variables to run:

• export ANCHOR_WALLET="../wallets/admin-keypair.json" (assumes you run client from inside the comm/app directory)
• export ANCHOR_PROVIDER_URL="https://api.devnet.solana.com"
• for sensor-client.js we need instead the sensor keypair: export ANCHOR_WALLET="../wallets/sensor-keypair.json"
• fake_sensor.py and sensor-client.js use msgpack to exchange data: pip install msgpack for python and npm i --save msgpack-lite for nodejs.
• to run them together (from comm/app directory) use: python3 ../../python/fake_sensor.py | node sensor-client.js
