PoA <> Substrate Bridge

DISCLAIMER: we recommend not using the bridge in "production" (to bridge significant amounts) just yet. it's missing a code audit and should still be considered alpha. we can't rule out that there are bugs that might result in loss of the bridged amounts. we'll update this disclaimer once that changes

(contracts only)

Bridge is able to pass arbitrary messages between an Ethereum Proof of Authority chain and a Substrate Chain - either Standalone or Polkadot Parachain.

TODO: Docs

These docs are very incomplete yet. Describe high-level goals here in the (near) future.

Issue 54 - close attack vector

https://github.com/paritytech/parity-bridge/issues/54

[x] figure out why tests pass locally and fail on travis
- was stuck there for a bit
- on travis we run the coverage tests. they insert additional statements into the contract code. that changes the gas cost. removed assertions that were sensitive to that
[x] add storage var estimatedGasCostOfWithdraw to HomeBridge
[x] modify withdraw as laid out in https://github.com/paritytech/parity-bridge/issues/54#issuecomment-351009494
[x] find good estimate for estimatedGasCostOfWithdraw
[x] extract functions that read values from message so they can be tested, reused and withdraw stays focused and is easier to read
[x] implement isValueInMessageLargeEnoughToCoverWithdrawCost
[x] make bridge processes (rust) call isValueInMessageLargeEnoughToCoverWithdrawCost and ignore messages for which it returns false (as laid out in https://github.com/paritytech/parity-bridge/issues/54#issuecomment-351009494)
- this truly shuts down the attack
[x] make transport tests run again
[x] create transport test that doesn't sendTransaction when call to isValueInMessageLargeEnoughToCoverWithdrawCost returns false
[x] add estimatedGasCostOfWithdraw to config of rust processes
[x] keep/increase solidity test coverage
- [x] test that values which don't cover costs are ignored
- [x] test that cost is subtracted from value and paid to relaying authority
- [x] test isValueInMessageLargeEnoughToCoverWithdrawCost
- [x] test getXFromMessage, etc in isolation
[x] documentation: readme section: recipient pays for withdraw relay costs
- recommended gas cost estimate

[WIP] ideas for syncing validator set from one chain to another as well as making bridge work with dynamic validator sets

thought i'd do this as a branch on the relevant repo. seems cleaner than a bunch of gists

ready for review/feedback: https://github.com/paritytech/parity-bridge/blob/validator_set_thoughts/docs/bridged_validator_set.md

writeup in progress: https://github.com/paritytech/parity-bridge/blob/validator_set_thoughts/docs/bridge_with_dynamic_validator_set.md

feedback and questions are greatly appreciated :)

Potential attack vector

Current version of the Bridge doesn't charge users for making withdraws so that Authorities running the Bridge have to cover all costs. This potentially allows an attacker to deplete Authorities’ funds.

Potential solution (proposed by @debris ):

Withdraws should not be free for users. The exact amount of gas that is spent on a withdraw should be measured and charged to users. It's a simple feature which could be added to function transfer() of ForeignBridge smart contract. Truffle tests should be written and run. Truffle tests for foreign contract are located in truffle/test/foreign.js.

Fails to load web3 on build

When I run cargo build -p parity-bridge --release I get the following error:

error: failed to load source for a dependency on `web3`                         

Caused by:

And indeed, the branch https://github.com/tomusdrw/rust-web3/tree/bridge has been deleted When trying to install web3 from master, I get lots of errors, like for example

Compile contracts using solcjs or solc
