To get all the correct dependencies activate direnv `direnv allow` and lorri `lorri shell`.\n\n### Rust Setup\n\nFirst, complete the [basic Rust setup instructions](./docs/rust-setup.md).\n\n### Run\n\nUse Rust's native `cargo` command to build and launch the template node:\n\n```sh\ncargo run --release -- --dev --tmp\n```\n\n### Build\n\nThe `cargo run` command will perform an initial build. Use the following command to build the node\nwithout launching it:\n\n```sh\ncargo build --release\n```\n\n### Embedded Docs\n\nOnce the project has been built, the following command can be used to explore all parameters and\nsubcommands:\n\n```sh\n./target/release/node-template -h\n```\n\n## Run\n\nThe provided `cargo run` command will launch a temporary node and its state will be discarded after\nyou terminate the process. After the project has been built, there are other ways to launch the\nnode.\n\n### Single-Node Development Chain\n\nThis command will start the single-node development chain with persistent state:\n\n```bash\n./target/release/node-template --dev\n```\n\nPurge the development chain's state:\n\n```bash\n./target/release/node-template purge-chain --dev\n```\n\nStart the development chain with detailed logging:\n\n```bash\nRUST_LOG=debug RUST_BACKTRACE=1 ./target/release/node-template -lruntime=debug --dev\n```\n\n### Connect with Polkadot-JS Apps Front-end\n\nOnce the node template is running locally, you can connect it with **Polkadot-JS Apps** front-end\nto interact with your chain. [Click here](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9944) connecting the Apps to your local node template.\n\n### Multi-Node Local Testnet\n\nIf you want to see the multi-node consensus algorithm in action, refer to\n[our Start a Private Network tutorial](https://substrate.dev/docs/en/tutorials/start-a-private-network/).\n\n## Template Structure\n\nA Substrate project such as this consists of a number of components that are spread across a few\ndirectories.\n\n### Node\n\nA blockchain node is an application that allows users to participate in a blockchain network.\nSubstrate-based blockchain nodes expose a number of capabilities:\n\n-   Networking: Substrate nodes use the [`libp2p`](https://libp2p.io/) networking stack to allow the\n    nodes in the network to communicate with one another.\n-   Consensus: Blockchains must have a way to come to\n    [consensus](https://substrate.dev/docs/en/knowledgebase/advanced/consensus) on the state of the\n    network. Substrate makes it possible to supply custom consensus engines and also ships with\n    several consensus mechanisms that have been built on top of\n    [Web3 Foundation research](https://research.web3.foundation/en/latest/polkadot/NPoS/index.html).\n-   RPC Server: A remote procedure call (RPC) server is used to interact with Substrate nodes.\n\nThere are several files in the `node` directory - take special note of the following:\n\n-   [`chain_spec.rs`](./node/src/chain_spec.rs): A\n    [chain specification](https://substrate.dev/docs/en/knowledgebase/integrate/chain-spec) is a\n    source code file that defines a Substrate chain's initial (genesis) state. Chain specifications\n    are useful for development and testing, and critical when architecting the launch of a\n    production chain. Take note of the `development_config` and `testnet_genesis` functions, which\n    are used to define the genesis state for the local development chain configuration. These\n    functions identify some\n    [well-known accounts](https://substrate.dev/docs/en/knowledgebase/integrate/subkey#well-known-keys)\n    and use them to configure the blockchain's initial state.\n-   [`service.rs`](./node/src/service.rs): This file defines the node implementation. Take note of\n    the libraries that this file imports and the names of the functions it invokes. In particular,\n    there are references to consensus-related topics, such as the\n    [longest chain rule](https://substrate.dev/docs/en/knowledgebase/advanced/consensus#longest-chain-rule),\n    the [Aura](https://substrate.dev/docs/en/knowledgebase/advanced/consensus#aura) block authoring\n    mechanism and the\n    [GRANDPA](https://substrate.dev/docs/en/knowledgebase/advanced/consensus#grandpa) finality\n    gadget.\n\nAfter the node has been [built](#build), refer to the embedded documentation to learn more about the\ncapabilities and configuration parameters that it exposes:\n\n```shell\n./target/release/node-template --help\n```\n\n### Runtime\n\nIn Substrate, the terms\n\"[runtime](https://substrate.dev/docs/en/knowledgebase/getting-started/glossary#runtime)\" and\n\"[state transition function](https://substrate.dev/docs/en/knowledgebase/getting-started/glossary#stf-state-transition-function)\"\nare analogous - they refer to the core logic of the blockchain that is responsible for validating\nblocks and executing the state changes they define. The Substrate project in this repository uses\nthe [FRAME](https://substrate.dev/docs/en/knowledgebase/runtime/frame) framework to construct a\nblockchain runtime. FRAME allows runtime developers to declare domain-specific logic in modules\ncalled \"pallets\". At the heart of FRAME is a helpful\n[macro language](https://substrate.dev/docs/en/knowledgebase/runtime/macros) that makes it easy to\ncreate pallets and flexibly compose them to create blockchains that can address\n[a variety of needs](https://www.substrate.io/substrate-users/).\n\nReview the [FRAME runtime implementation](./runtime/src/lib.rs) included in this template and note\nthe following:\n\n-   This file configures several pallets to include in the runtime. Each pallet configuration is\n    defined by a code block that begins with `impl $PALLET_NAME::Config for Runtime`.\n-   The pallets are composed into a single runtime by way of the\n    [`construct_runtime!`](https://crates.parity.io/frame_support/macro.construct_runtime.html)\n    macro, which is part of the core\n    [FRAME Support](https://substrate.dev/docs/en/knowledgebase/runtime/frame#support-library)\n    library.\n\n### Pallets\n\nThe runtime in this project is constructed using many FRAME pallets that ship with the\n[core Substrate repository](https://github.com/paritytech/substrate/tree/master/frame) and a\ntemplate pallet that is [defined in the `pallets`](./pallets/template/src/lib.rs) directory.\n\nA FRAME pallet is compromised of a number of blockchain primitives:\n\n-   Storage: FRAME defines a rich set of powerful\n    [storage abstractions](https://substrate.dev/docs/en/knowledgebase/runtime/storage) that makes\n    it easy to use Substrate's efficient key-value database to manage the evolving state of a\n    blockchain.\n-   Dispatchables: FRAME pallets define special types of functions that can be invoked (dispatched)\n    from outside of the runtime in order to update its state.\n-   Events: Substrate uses [events](https://substrate.dev/docs/en/knowledgebase/runtime/events) to\n    notify users of important changes in the runtime.\n-   Errors: When a dispatchable fails, it returns an error.\n-   Config: The `Config` configuration interface is used to define the types and parameters upon\n    which a FRAME pallet depends.\n\n### Run in Docker\n\nFirst, install [Docker](https://docs.docker.com/get-docker/) and\n[Docker Compose](https://docs.docker.com/compose/install/).\n\nThen run the following command to start a single node development chain.\n\n```bash\n./scripts/docker_run.sh\n```\n\nThis command will firstly compile your code, and then start a local development network. You can\nalso replace the default command (`cargo build --release \u0026\u0026 ./target/release/node-template --dev --ws-external`)\nby appending your own. A few useful ones are as follow.\n\n```bash\n# Run Substrate node without re-compiling\n./scripts/docker_run.sh ./target/release/node-template --dev --ws-external\n\n# Purge the local dev chain\n./scripts/docker_run.sh ./target/release/node-template purge-chain --dev\n\n# Check whether the code is compilable\n./scripts/docker_run.sh cargo check\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzacksleo%2Fsubstrate-poe-dapp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fzacksleo%2Fsubstrate-poe-dapp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzacksleo%2Fsubstrate-poe-dapp/lists"}
