Stafi-blockchain

Building

Linux and Mac

For Unix-based operating systems, you should run the following commands:

curl https://sh.rustup.rs -sSf | sh

rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
rustup update stable
cargo install --git https://github.com/alexcrichton/wasm-gc

You will also need to install the following packages:

• Linux:

  sudo apt install cmake pkg-config libssl-dev git clang libclang-dev

• Mac:

  brew install cmake pkg-config openssl git llvm

To finish installation of Stafi-blockchain, jump down to shared steps.

Shared Steps

Then, grab the source code:

git clone git@github.com:cennznet/stafi-blockchain.git
cd stafi-blockchain

Then build the code:

./scripts/build.sh          # Builds the WebAssembly binaries
cargo build                 # Builds all native code

You can run all the tests if you like:

cargo test --all

Or just run the tests of a specific package (i.e. cargo test -p srml-assets)

You can start a development chain with:

cargo run --dev

Detailed logs may be shown by running the node with the following environment variables set: RUST_LOG=debug RUST_BACKTRACE=1 cargo run --dev.

If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two validator nodes for Alice and Bob, who are the initial authorities of the genesis chain specification that have been endowed with a testnet DOTs. We’ll give each node a name and expose them so they are listed on Telemetry . You’ll need two terminals windows open.

We’ll start Alice’s node first on default TCP port 30333 with her chain database stored locally at /tmp/alice. The Bootnode ID of her node is QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN, which is generated from the --node-key value that we specify below:

cargo run --release \
  --base-path /tmp/alice \
  --chain=local \
  --alice \
  --node-key 0000000000000000000000000000000000000000000000000000000000000001 \
  --telemetry-url ws://telemetry.polkadot.io:1024 \
  --validator

In the second terminal, we’ll run the following to start Bob’s node on a different TCP port of 30334, and with his chain database stored locally at /tmp/bob. We’ll specify a value for the --bootnodes option that will connect his node to Alice’s Bootnode ID on TCP port 30333:

cargo run --release \
  --base-path /tmp/bob \
  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN \
  --chain=local \
  --bob \
  --port 30334 \
  --telemetry-url ws://telemetry.polkadot.io:1024 \
  --validator

Additional CLI usage options are available and may be shown by running cargo run --help.
