### Difference from Parity Bridge
Although POA bridge initially was based on [Parity Brigde](https://github.com/paritytech/parity-bridge), eventually it
was re-worked:
* support of a gas price oracle introduced;
* RPC is used instead of IPC;
* sending of bridge approvals enhanced as so performance increased drammatically;
* error handling improved to be compatible with Linux systemd faclity;
* bridge configuration parameters are being got from bridge contracts so they don't need to be synchronized among several bridge instances;
* bridge contracts was segregated into [the separate project](https://github.com/poanetwork/poa-bridge-contracts) and their deployment
is independent from the Rust side of the bridge. Now bridge contracts:
* ERC20 is separated from the brdige contracts
* are upgradable and you don't need to re-configure bridge instances and DApps to use new version of contracts
* set of validators can be changed without necessity to re-deploy bridge contracts
### How to build
Requires `rust` and `cargo`: [installation instructions.](https://www.rust-lang.org/en-US/install.html)
