* Update dependencies Upgrades Substrate based dependencies from v2.0.0 -> v2.0.0-alpha.1 and uses the `jsonrpsee`'s new feature flags. The actual code hasn't been updated though, so this won't compile. * Use `RawClient`s from `jsonrpsee` * Update to use jsonrpsee's new API * Hook up Ethereum Bridge Runtime, Relay, and Node Runtime * Bump `parity-crypto` from v0.4 to v0.6 Fixes error when trying to compile tests. This was caused by `parity-crypto` v0.4's use of `parity-secp256k1` over `secp256k1'. Using the Parity fork meant multiple version of the same underlying C library were being pulled in. `parity-crypto` v0.6 moved away from this, only relying on `secp256k1` thus fixing the issue.
Substrate-to-Substrate Bridge Relay
The bridge relay is a process that connects to running Substrate nodes and sends data over the Substrate-to-Substrate bridge. The process communicates with the nodes over the JSON-RPC interface and reads data from the relays information required by the bridge pallet using runtime calls and writes data to the modules by constructing and submitting extrinsics.
For more details, see the design document.
Status
This is a not-in-progress prototype.
Running in development
Run two development Substrate chains:
> TMPDIR=(mktemp -d)
> cd $TMPDIR
> substrate build-spec --dev > red-spec.json
> cp red-spec.json blue-spec.json
# Modify the chain spec in an editor so that the genesis hashes of the two chains differ.
# For example, double one of the balances in '$.genesis.runtime.balances.balances'.
> substrate --chain red-spec.json --alice --base-path ./red --port 30343 --ws-port 9954
> substrate --chain blue-spec.json --alice --base-path ./blue --port 30353 --ws-port 9964
Now run the bridge relay:
> target/release/substrate-bridge --base-path ./relay \
--rpc-url ws://localhost:9954 \
--rpc-url ws://localhost:9964
