+# RepuChain
+
+RepuChain is a solution to manage reputations in the Polkadot ecosystem.
+Its purpose is to make a system chain what store the reputation of an address based on its behavior and provide a simplified way to set and get blocks via XCM.
+
+## Getting Started
+
+Depending on your operating system and Rust version, there might be additional packages required to compile this template.
+Check the [Install](https://docs.substrate.io/install/) instructions for your platform for the most common dependencies.
+Alternatively, you can use one of the [alternative installation](#alternatives-installations) options.
+
+### Build
+
+Use the following command to build the node without launching it:
+
+```sh
+cargo build --release
+```
+
+### Embedded Docs
+
+After you build the project, you can use the following command to explore its parameters and subcommands:
+
+```sh
+./target/release/node-template -h
+```
+
+You can generate and view the [Rust Docs](https://doc.rust-lang.org/cargo/commands/cargo-doc.html) for this template with this command:
+
+```sh
+cargo +nightly doc --open
+```
+
+### Single-Node Development Chain
+
+The following command starts a single-node development chain that doesn't persist state:
+
+```sh
+./target/release/node-template --dev
+```
+
+To purge the development chain's state, run the following command:
+
+```sh
+./target/release/node-template purge-chain --dev
+```
+
+To start the development chain with detailed logging, run the following command:
+
+```sh
+RUST_BACKTRACE=1 ./target/release/node-template -ldebug --dev
+```
+
+Development chains:
+
+- Maintain state in a `tmp` folder while the node is running.
+- Use the **Alice** and **Bob** accounts as default validator authorities.
+- Use the **Alice** account as the default `sudo` account.
+- Are preconfigured with a genesis state (`/node/src/chain_spec.rs`) that includes several prefunded development accounts.
+
+
+To persist chain state between runs, specify a base path by running a command similar to the following:
+
+```sh
+// Create a folder to use as the db base path
+$ mkdir my-chain-state
+
+// Use of that folder to store the chain state
+$ ./target/release/node-template --dev --base-path ./my-chain-state/
+
+// Check the folder structure created inside the base path after running the chain
+$ ls ./my-chain-state
+chains
+$ ls ./my-chain-state/chains/
+dev
+$ ls ./my-chain-state/chains/dev
+db keystore network
+```
+
+### Connect with Polkadot-JS Apps Front-End
+
+After you start the node template locally, you can interact with it using the hosted version of the [Polkadot/Substrate Portal](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9944) front-end by connecting to the local node endpoint.
+A hosted version is also available on [IPFS (redirect) here](https://dotapps.io/) or [IPNS (direct) here](ipns://dotapps.io/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/explorer).
+You can also find the source code and instructions for hosting your own instance on the [polkadot-js/apps](https://github.com/polkadot-js/apps) repository.
+
+### Multi-Node Local Testnet
+
+If you want to see the multi-node consensus algorithm in action, see [Simulate a network](https://docs.substrate.io/tutorials/build-a-blockchain/simulate-network/).
+
+## Template Structure
+
+A Substrate project such as this consists of a number of components that are spread across a few directories.
+
+### Node
+
+A blockchain node is an application that allows users to participate in a blockchain network.
+Substrate-based blockchain nodes expose a number of capabilities:
+
+- Networking: Substrate nodes use the [`libp2p`](https://libp2p.io/) networking stack to allow the
+  nodes in the network to communicate with one another.
+- Consensus: Blockchains must have a way to come to [consensus](https://docs.substrate.io/fundamentals/consensus/) on the state of the network.
+  Substrate makes it possible to supply custom consensus engines and also ships with several consensus mechanisms that have been built on top of [Web3 Foundation research](https://research.web3.foundation/en/latest/polkadot/NPoS/index.html).
+- RPC Server: A remote procedure call (RPC) server is used to interact with Substrate nodes.
+
+There are several files in the `node` directory.
+Take special note of the following:
+
+- [`chain_spec.rs`](./node/src/chain_spec.rs): A [chain specification](https://docs.substrate.io/build/chain-spec/) is a source code file that defines a Substrate chain's initial (genesis) state.
+  Chain specifications are useful for development and testing, and critical when architecting the launch of a production chain.
+  Take note of the `development_config` and `testnet_genesis` functions,.
+  These functions are used to define the genesis state for the local development chain configuration.
+  These functions identify some [well-known accounts](https://docs.substrate.io/reference/command-line-tools/subkey/) and use them to configure the blockchain's initial state.
+- [`service.rs`](./node/src/service.rs): This file defines the node implementation.
+  Take note of the libraries that this file imports and the names of the functions it invokes.
+  In particular, there are references to consensus-related topics, such as the [block finalization and forks](https://docs.substrate.io/fundamentals/consensus/#finalization-and-forks) and other [consensus mechanisms](https://docs.substrate.io/fundamentals/consensus/#default-consensus-models) such as Aura for block authoring and GRANDPA for finality.
+
+
+
+### Runtime
+
+In Substrate, the terms "runtime" and "state transition function" are analogous.
+Both terms refer to the core logic of the blockchain that is responsible for validating blocks and executing the state changes they define.
+The Substrate project in this repository uses [FRAME](https://docs.substrate.io/learn/runtime-development/#frame) to construct a blockchain runtime.
+FRAME allows runtime developers to declare domain-specific logic in modules called "pallets".
+At the heart of FRAME is a helpful [macro language](https://docs.substrate.io/reference/frame-macros/) that makes it easy to create pallets and flexibly compose them to create blockchains that can address [a variety of needs](https://substrate.io/ecosystem/projects/).
+
+Review the [FRAME runtime implementation](./runtime/src/lib.rs) included in this template and note the following:
+
+- This file configures several pallets to include in the runtime.
+  Each pallet configuration is defined by a code block that begins with `impl $PALLET_NAME::Config for Runtime`.
+- The pallets are composed into a single runtime by way of the [`construct_runtime!`](https://paritytech.github.io/substrate/master/frame_support/macro.construct_runtime.html) macro, which is part of the [core FRAME pallet library](https://docs.substrate.io/reference/frame-pallets/#system-pallets).
+
+### Pallets
+
+The runtime in this project is constructed using many FRAME pallets that ship with [the Substrate repository](https://github.com/paritytech/substrate/tree/master/frame) and a template pallet that is [defined in the `pallets`](./pallets/template/src/lib.rs) directory.
+
+A FRAME pallet is comprised of a number of blockchain primitives, including:
+
+- Storage: FRAME defines a rich set of powerful [storage abstractions](https://docs.substrate.io/build/runtime-storage/) that makes it easy to use Substrate's efficient key-value database to manage the evolving state of a blockchain.
+- Dispatchables: FRAME pallets define special types of functions that can be invoked (dispatched) from outside of the runtime in order to update its state.
+- Events: Substrate uses [events](https://docs.substrate.io/build/events-and-errors/) to notify users of significant state changes.
+- Errors: When a dispatchable fails, it returns an error.
+
+Each pallet has its own `Config` trait which serves as a configuration interface to generically define the types and parameters it depends on.
+
+## Alternatives Installations
+
+Instead of installing dependencies and building this source directly, consider the following alternatives.
+
+### Nix
+
+Install [nix](https://nixos.org/) and
+[nix-direnv](https://github.com/nix-community/nix-direnv) for a fully plug-and-play
+experience for setting up the development environment.
+To get all the correct dependencies, activate direnv `direnv allow`.
+
+### Docker
+
+Please follow the [Substrate Docker instructions here](https://github.com/paritytech/substrate/blob/master/docker/README.md) to build the Docker container with the Substrate Node Template binary.

+title: Installation
+---
+
+This guide is for reference only, please check the latest information on getting starting with Substrate 
+[here](https://docs.substrate.io/main-docs/install/).
+
+This page will guide you through the **2 steps** needed to prepare a computer for **Substrate** development.
+Since Substrate is built with [the Rust programming language](https://www.rust-lang.org/), the first
+thing you will need to do is prepare the computer for Rust development - these steps will vary based
+on the computer's operating system. Once Rust is configured, you will use its toolchains to interact
+with Rust projects; the commands for Rust's toolchains will be the same for all supported,
+Unix-based operating systems.
+
+## Build dependencies
+
+Substrate development is easiest on Unix-based operating systems like macOS or Linux. The examples
+in the [Substrate Docs](https://docs.substrate.io) use Unix-style terminals to demonstrate how to
+interact with Substrate from the command line.
+
+### Ubuntu/Debian
+
+Use a terminal shell to execute the following commands:
+
+```bash
+sudo apt update
+# May prompt for location information
+sudo apt install -y git clang curl libssl-dev llvm libudev-dev
+```
+
+### Arch Linux
+
+Run these commands from a terminal:
+
+```bash
+pacman -Syu --needed --noconfirm curl git clang
+```
+
+### Fedora
+
+Run these commands from a terminal:
+
+```bash
+sudo dnf update
+sudo dnf install clang curl git openssl-devel
+```
+
+### OpenSUSE
+
+Run these commands from a terminal:
+
+```bash
+sudo zypper install clang curl git openssl-devel llvm-devel libudev-devel
+```
+
+### macOS

+Open the Terminal application and execute the following commands:
+

+# Install Homebrew if necessary https://brew.sh/

+
+# Make sure Homebrew is up-to-date, install openssl
+brew update
+brew install openssl
+```
+
+### Windows
+
+**_PLEASE NOTE:_** Native Windows development of Substrate is _not_ very well supported! It is _highly_
+recommend to use [Windows Subsystem Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10)
+(WSL) and follow the instructions for [Ubuntu/Debian](#ubuntudebian).
+Please refer to the separate
+[guide for native Windows development](https://docs.substrate.io/main-docs/install/windows/).
+
+## Rust developer environment
+
+This guide uses <https://rustup.rs> installer and the `rustup` tool to manage the Rust toolchain.
+First install and configure `rustup`:
+
+```bash
+# Install
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+# Configure
+source ~/.cargo/env
+```
+
+Configure the Rust toolchain to default to the latest stable version, add nightly and the nightly wasm target:
+
+```bash
+rustup default stable
+rustup update
+rustup update nightly
+rustup target add wasm32-unknown-unknown --toolchain nightly
+```
+
+## Test your set-up
+
+Now the best way to ensure that you have successfully prepared a computer for Substrate
+development is to follow the steps in [our first Substrate tutorial](https://docs.substrate.io/tutorials/v3/create-your-first-substrate-chain/).
+
+## Troubleshooting Substrate builds
+
+Sometimes you can't get the Substrate node template
+to compile out of the box. Here are some tips to help you work through that.
+
+### Rust configuration check
+
+To see what Rust toolchain you are presently using, run:
+
+```bash
+rustup show
+```
+
+This will show something like this (Ubuntu example) output:
+
+```text
+Default host: x86_64-unknown-linux-gnu
+rustup home:  /home/user/.rustup
+
+installed toolchains
+--------------------
+
+stable-x86_64-unknown-linux-gnu (default)
+nightly-2020-10-06-x86_64-unknown-linux-gnu
+nightly-x86_64-unknown-linux-gnu
+
+installed targets for active toolchain
+--------------------------------------
+
+wasm32-unknown-unknown
+x86_64-unknown-linux-gnu
+
+active toolchain
+----------------
+
+stable-x86_64-unknown-linux-gnu (default)
+rustc 1.50.0 (cb75ad5db 2021-02-10)
+```
+
+As you can see above, the default toolchain is stable, and the
+`nightly-x86_64-unknown-linux-gnu` toolchain as well as its `wasm32-unknown-unknown` target is installed.
+You also see that `nightly-2020-10-06-x86_64-unknown-linux-gnu` is installed, but is not used unless explicitly defined as illustrated in the [specify your nightly version](#specifying-nightly-version)
+section.
+
+### WebAssembly compilation
+
+Substrate uses [WebAssembly](https://webassembly.org) (Wasm) to produce portable blockchain
+runtimes. You will need to configure your Rust compiler to use
+[`nightly` builds](https://doc.rust-lang.org/book/appendix-07-nightly-rust.html) to allow you to
+compile Substrate runtime code to the Wasm target.
+
+> There are upstream issues in Rust that need to be resolved before all of Substrate can use the stable Rust toolchain.
+> [This is our tracking issue](https://github.com/paritytech/substrate/issues/1252) if you're curious as to why and how this will be resolved.
+
+#### Latest nightly for Substrate `master`
+
+Developers who are building Substrate _itself_ should always use the latest bug-free versions of
+Rust stable and nightly. This is because the Substrate codebase follows the tip of Rust nightly,
+which means that changes in Substrate often depend on upstream changes in the Rust nightly compiler.
+To ensure your Rust compiler is always up to date, you should run:
+
+```bash
+rustup update
+rustup update nightly
+rustup target add wasm32-unknown-unknown --toolchain nightly
+```
+
+> NOTE: It may be necessary to occasionally rerun `rustup update` if a change in the upstream Substrate
+> codebase depends on a new feature of the Rust compiler. When you do this, both your nightly
+> and stable toolchains will be pulled to the most recent release, and for nightly, it is
+> generally _not_ expected to compile WASM without error (although it very often does).
+> Be sure to [specify your nightly version](#specifying-nightly-version) if you get WASM build errors
+> from `rustup` and [downgrade nightly as needed](#downgrading-rust-nightly).
+
+#### Rust nightly toolchain
+
+If you want to guarantee that your build works on your computer as you update Rust and other
+dependencies, you should use a specific Rust nightly version that is known to be
+compatible with the version of Substrate they are using; this version will vary from project to
+project and different projects may use different mechanisms to communicate this version to
+developers. For instance, the Polkadot client specifies this information in its
+[release notes](https://github.com/paritytech/polkadot/releases).
+
+```bash
+# Specify the specific nightly toolchain in the date below:
+rustup install nightly-<yyyy-MM-dd>
+```
+
+#### Wasm toolchain
+
+Now, configure the nightly version to work with the Wasm compilation target:
+
+```bash
+rustup target add wasm32-unknown-unknown --toolchain nightly-<yyyy-MM-dd>
+```
+
+### Specifying nightly version
+
+Use the `WASM_BUILD_TOOLCHAIN` environment variable to specify the Rust nightly version a Substrate
+project should use for Wasm compilation:
+
+```bash
+WASM_BUILD_TOOLCHAIN=nightly-<yyyy-MM-dd> cargo build --release
+```
+
+> Note that this only builds _the runtime_ with the specified nightly. The rest of project will be
+> compiled with **your default toolchain**, i.e. the latest installed stable toolchain.
+
+### Downgrading Rust nightly
+
+If your computer is configured to use the latest Rust nightly and you would like to downgrade to a
+specific nightly version, follow these steps:
+
+```bash
+rustup uninstall nightly
+rustup install nightly-<yyyy-MM-dd>
+rustup target add wasm32-unknown-unknown --toolchain nightly-<yyyy-MM-dd>
+```
