Process finality proofs in solidity PoA -> Substrate contract (#69)
* solidity contract * continue * upd * cargo update * fixes * ehtereum_headers -> headers * extracted some common stuff * ethereum_sync.rs -> sync.rs * make sync generic * continue extracting * continue * add eth-contract argument * continue * some fixes * contract v2 * continue * more fixes * more fixes * deal with duplicated params * removed multiple call_rpc variants * bail_on_error!() * fn submit_ethereum_transaction * more fixes * cargo fmt --all * fix * bail_on_arg_error!() * fix * fix * remove async_extra stuff * start work on finality builtin remove async_extra stuff continue continue local testnet (Alice + Bob) for node * added TODO * substrate-bridge.json -> substrate-bridge-abi.json * get rid of substrate transactions hashes * get rid of ethereum transactions hashes * extracted contract bytecode to separate file * cargo fmt --all * avoid duplicate import in contracts * removed Default::default() * swapped configurations for sub2eth && eth2sub * fix compilation * do not double gas limit when submitting Substrate headers * fix finality storage * at least 1 validator required * shift_session_manager_works * cargo fmt --all * solidity contract removed * consts * extracted solc compilation details to separate file * removed (obsolete in future Vec<u8> justification) * fixed cli option description * fix typos * fix grumble * extracted constants * log decoded header * new substrate version + actually verify justification * intermediate cargo fmt --all * comments * disable completion data resubmission * increased timeouts + _MS -> Duration * forget completion data after submission * builtin tests * headers tests * cargo fmt --all * update contract * Update relays/ethereum/src/ethereum_sync_loop.rs Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Update relays/ethereum/src/ethereum_sync_loop.rs Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * added docs * OwnedFutureOutput * more docs fixes * cargo fmt --all * encode headers * consts + docs * aliases again * cargo fmt --all * Update relays/ethereum/src/ethereum_sync_loop.rs Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Update relays/ethereum/src/ethereum_sync_loop.rs Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Use Duration::from_secs() instead of from_millis() * grumbles * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * incomplete_headers_are_still_incomplete_after_advance * add hex-encoded headers to substrate_header_without_signal_parsed * cargo fmt --all * Update relays/ethereum/src/sync_loop.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * Update relays/ethereum/src/headers.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * added comments on Extra and Completion Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com>
