Polkadot
Implementation of a https://polkadot.io node in Rust.
To play
If you'd like to play with Polkadot, you'll need to install a client like this one. First, get Rust (1.26.1 or later) and the support software if you don't already have it:
curl https://sh.rustup.rs -sSf | sh
sudo apt install make clang
Then, install Polkadot PoC-1:
cargo install --git https://github.com/paritytech/polkadot.git --branch v0.1
You'll now have a polkadot binary installed to your PATH. You can drop the
--branch v0.1 or run cargo install --git https://github.com/paritytech/polkadot.git polkadot
to get the very latest version of Polkadot, but these instructions will not work in that case.
Development
You can run a simple single-node development "network" on your machine by running in a terminal:
polkadot --chain=dev --validator --key Alice
You can muck around by cloning and building the http://github.com/paritytech/polka-ui and http://github.com/paritytech/polkadot-ui or just heading to https://polkadot.js.org/apps.
PoC-1 Testnet
You can also connect to the global PoC-1 testnet. To do this, just use:
polkadot --chain=poc-1
If you want to do anything on it (not that there's much to do), then you'll need to get some PoC-1 testnet DOTs. Ask in the Polkadot watercooler.
Local Two-node Testnet
If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet. You'll need two terminals open. In one, run:
polkadot --chain=local --validator --key Alice -d /tmp/alice
and in the other, run:
polkadot --chain=local --validator --key Bob -d /tmp/bob --port 30334 --bootnodes 'enode://ALICE_BOOTNODE_ID_HERE@127.0.0.1:30333'
Ensure you replace ALICE_BOOTNODE_ID_HERE with the node ID from the output of
the first terminal.
Hacking on Polkadot
If you'd actually like hack on Polkadot, you can just grab the source code and build it. Ensure you have Rust and the support software installed:
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
cargo install --git https://github.com/pepyakin/wasm-export-table.git
sudo apt install cmake pkg-config libssl-dev
Then, grab the Polkadot source code:
git clone https://github.com/paritytech/polkadot.git
cd polkadot
Then build the code:
./build.sh # Builds the WebAssembly binaries
cargo build # Builds all native code
You can run the tests if you like:
cargo test --all
You can start a development chain with:
cargo run -- --chain=dev --validator --key Alice
