Description \u003ca id=\"chapter-001\"\u003e\u003c/a\u003e\n\n**Built for mission-critical use**: Miners, service providers, and exchanges need fast synchronisation and maximum uptime. OpenEthereum provides the core infrastructure essential for speedy and reliable services.\n\n- Clean, modular codebase for easy customisation\n- Advanced CLI-based client\n- Minimal memory and storage footprint\n- Synchronise in hours, not days with Warp Sync\n- Modular for light integration into your service or product\n\n## 2. Technical Overview \u003ca id=\"chapter-002\"\u003e\u003c/a\u003e\n\nOpenEthereum's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing OpenEthereum using the **Rust programming language**. OpenEthereum is licensed under the GPLv3 and can be used for all your Ethereum needs.\n\nBy default, OpenEthereum runs a JSON-RPC HTTP server on port `:8545` and a Web-Sockets server on port `:8546`. This is fully configurable and supports a number of APIs.\n\nIf you run into problems while using OpenEthereum, check out the [old wiki for documentation](https://openethereum.github.io/), feel free to [file an issue in this repository](https://github.com/openethereum/openethereum/issues/new), or hop on our [Discord](https://discord.io/openethereum) chat room to ask a question. We are glad to help!\n\nYou can download OpenEthereum's latest release at [the releases page](https://github.com/openethereum/openethereum/releases) or follow the instructions below to build from source. Read the [CHANGELOG.md](CHANGELOG.md) for a list of all changes between different versions.\n\n## 3. Building \u003ca id=\"chapter-003\"\u003e\u003c/a\u003e\n\n### 3.1 Build Dependencies \u003ca id=\"chapter-0031\"\u003e\u003c/a\u003e\n\nOpenEthereum requires **latest stable Rust version** to build.\n\nWe recommend installing Rust through [rustup](https://www.rustup.rs/). If you don't already have `rustup`, you can install it like this:\n\n- Linux:\n  ```bash\n  $ curl https://sh.rustup.rs -sSf | sh\n  ```\n\n  OpenEthereum also requires `clang` (\u003e= 9.0), `clang++`, `pkg-config`, `file`, `make`, and `cmake` packages to be installed.\n\n- OSX:\n  ```bash\n  $ curl https://sh.rustup.rs -sSf | sh\n  ```\n\n  `clang` is required. It comes with Xcode command line tools or can be installed with homebrew.\n\n- Windows:\n  Make sure you have Visual Studio 2015 with C++ support installed. Next, download and run the `rustup` installer from\n  https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe, start \"VS2015 x64 Native Tools Command Prompt\", and use the following command to install and set up the `msvc` toolchain:\n  ```bash\n  $ rustup default stable-x86_64-pc-windows-msvc\n  ```\n\nOnce you have `rustup` installed, then you need to install:\n* [Perl](https://www.perl.org)\n* [Yasm](https://yasm.tortall.net)\n\nMake sure that these binaries are in your `PATH`. After that, you should be able to build OpenEthereum from source.\n\n### 3.2 Build from Source Code \u003ca id=\"chapter-0032\"\u003e\u003c/a\u003e\n\n```bash\n# download OpenEthereum code\n$ git clone https://github.com/openethereum/openethereum\n$ cd openethereum\n\n# build in release mode\n$ cargo build --release --features final\n```\n\nThis produces an executable in the `./target/release` subdirectory.\n\nNote: if cargo fails to parse manifest try:\n\n```bash\n$ ~/.cargo/bin/cargo build --release\n```\n\nNote, when compiling a crate and you receive errors, it's in most cases your outdated version of Rust, or some of your crates have to be recompiled. Cleaning the repository will most likely solve the issue if you are on the latest stable version of Rust, try:\n\n```bash\n$ cargo clean\n```\n\nThis always compiles the latest nightly builds. If you want to build stable, do a\n\n```bash\n$ git checkout stable\n```\n\n### 3.3 Starting OpenEthereum \u003ca id=\"chapter-0034\"\u003e\u003c/a\u003e\n\n#### Manually\n\nTo start OpenEthereum manually, just run\n\n```bash\n$ ./target/release/openethereum\n```\n\nso OpenEthereum begins syncing the Ethereum blockchain.\n\n#### Using `systemd` service file\n\nTo start OpenEthereum as a regular user using `systemd` init:\n\n1. Copy `./scripts/openethereum.service` to your\n`systemd` user directory (usually `~/.config/systemd/user`).\n2. Copy release to bin folder, write `sudo install ./target/release/openethereum /usr/bin/openethereum`\n3. To configure OpenEthereum, see [our wiki](https://openethereum.github.io/Configuring-OpenEthereum) for details.\n\n## 4. Testing \u003ca id=\"chapter-004\"\u003e\u003c/a\u003e\n\nDownload the required test files: `git submodule update --init --recursive`. You can run tests with the following commands:\n\n* **All** packages\n  ```\n  cargo test --all\n  ```\n\n* Specific package\n  ```\n  cargo test --package \u003cspec\u003e\n  ```\n\nReplace `\u003cspec\u003e` with one of the packages from the [package list](#package-list) (e.g. `cargo test --package evmbin`).\n\nYou can show your logs in the test output by passing `--nocapture` (i.e. `cargo test --package evmbin -- --nocapture`)\n\n## 5. Documentation \u003ca id=\"chapter-005\"\u003e\u003c/a\u003e\n\nBe sure to [check out our wiki](https://openethereum.github.io/) for more information.\n\n### Viewing documentation for OpenEthereum packages\n\nYou can generate documentation for OpenEthereum Rust packages that automatically opens in your web browser using [rustdoc with Cargo](https://doc.rust-lang.org/rustdoc/what-is-rustdoc.html#using-rustdoc-with-cargo) (of the The Rustdoc Book), by running the the following commands:\n\n* **All** packages\n  ```\n  cargo doc --document-private-items --open\n  ```\n\n* Specific package\n  ```\n  cargo doc --package \u003cspec\u003e -- --document-private-items --open\n  ```\n\nUse`--document-private-items` to also view private documentation and `--no-deps` to exclude building documentation for dependencies.\n\nReplacing `\u003cspec\u003e` with one of the following from the details section below (i.e. `cargo doc --package openethereum --open`):\n\n\u003ca id=\"package-list\"\u003e\u003c/a\u003e\n**Package List**\n\u003cdetails\u003e\u003cp\u003e\n\n* OpenEthereum Client Application\n  ```bash\n  openethereum\n  ```\n* OpenEthereum Account Management, Key Management Tool, and Keys Generator\n  ```bash\n  ethcore-accounts, ethkey-cli, ethstore, ethstore-cli\n  ```\n* OpenEthereum Chain Specification\n  ```bash\n  chainspec\n  ```\n* OpenEthereum CLI Signer Tool \u0026 RPC Client\n  ```bash\n  cli-signer parity-rpc-client\n  ```\n* OpenEthereum Ethash \u0026 ProgPoW Implementations\n  ```bash\n  ethash\n  ```\n* EthCore Library\n  ```bash\n  ethcore\n  ```\n  * OpenEthereum Blockchain Database, Test Generator, Configuration,\nCaching, Importing Blocks, and Block Information\n    ```bash\n    ethcore-blockchain\n    ```\n  * OpenEthereum Contract Calls and Blockchain Service \u0026 Registry Information\n    ```bash\n    ethcore-call-contract\n    ```\n  * OpenEthereum Database Access \u0026 Utilities, Database Cache Manager\n    ```bash\n    ethcore-db\n    ```\n  * OpenEthereum Virtual Machine (EVM) Rust Implementation\n    ```bash\n    evm\n    ```\n  * OpenEthereum Light Client Implementation\n    ```bash\n    ethcore-light\n    ```\n  * Smart Contract based Node Filter, Manage Permissions of Network Connections\n    ```bash\n    node-filter\n    ```\n  * OpenEthereum Client \u0026 Network Service Creation \u0026 Registration with the I/O Subsystem\n    ```bash\n    ethcore-service\n    ```\n  * OpenEthereum Blockchain Synchronization\n    ```bash\n    ethcore-sync\n    ```\n  * OpenEthereum Common Types\n    ```bash\n    common-types\n    ```\n  * OpenEthereum Virtual Machines (VM) Support Library\n    ```bash\n    vm\n    ```\n  * OpenEthereum WASM Interpreter\n    ```bash\n    wasm\n    ```\n  * OpenEthereum WASM Test Runner\n    ```bash\n    pwasm-run-test\n    ```\n  * OpenEthereum EVM Implementation\n    ```bash\n    evmbin\n    ```\n  * OpenEthereum JSON Deserialization\n    ```bash\n    ethjson\n    ```\n  * OpenEthereum State Machine Generalization for Consensus Engines\n    ```bash\n    parity-machine\n    ```\n* OpenEthereum Miner Interface\n  ```bash\n  ethcore-miner parity-local-store price-info ethcore-stratum using_queue\n  ```\n* OpenEthereum Logger Implementation\n  ```bash\n  ethcore-logger\n  ```\n* OpenEthereum JSON-RPC Servers\n  ```bash\n  parity-rpc\n  ```\n* OpenEthereum Updater Service\n  ```bash\n  parity-updater parity-hash-fetch\n  ```\n* OpenEthereum Core Libraries (`util`)\n  ```bash\n  accounts-bloom blooms-db dir eip-712 fake-fetch fastmap fetch ethcore-io\n  journaldb keccak-hasher len-caching-lock memory-cache memzero\n  migration-rocksdb ethcore-network ethcore-network-devp2p panic_hook\n  patricia-trie-ethereum registrar rlp_compress stats\n  time-utils triehash-ethereum unexpected parity-version\n  ```\n\n\u003c/p\u003e\u003c/details\u003e\n\n## 6.
