INSTALLATION · SUBSTRATE DEVELOPER HUB 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, 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 SET UP YOUR COMPUTER · SUBSTRATE DEVELOPER HUB Normally, we would teach you more about the Substrate blockchain development framework, however, setting up your computer for Substrate development can take a while. GLOSSARY · SUBSTRATE DEVELOPER HUB A single element of a blockchain that cryptographically binds a set of extrinsic data (the "body") to a " header ". Blocks are arranged into a tree through parent pointers (implemented as a hash of the parent) and the tree is pruned into a list via a fork-choice rule, and optional finality gadget. RUNTIME · SUBSTRATE DEVELOPER HUB The runtime of a blockchain is the business logic that defines its behavior. In Substrate-based chains, the runtime is referred to as the "state transition function"; it is where Substrate developers define the storage items that are used to represent the blockchain's state as well as the functions that allow blockchain users to make changes tothis state.
START A PRIVATE NETWORK · SUBSTRATE DEVELOPER HUB Before we even get started, let's lay out what we are going to do over the course of this tutorial. We will: Launch a Substrate blockchain network based on a template project. Generate ed25519 and sr25519 key-pairs for use as a network authority. Create and edit a PALLETS · SUBSTRATE DEVELOPER HUB Pallets. The following documentation is written for technical audiences, familiar with the Rust programming language. It is a top-level entry point for FRAME runtime developement in Substrate. If you are just getting started with Substrate runtime development, we suggest you try our introductory tutorial for creating your firstSubstrate chain.
THE SUBKEY TOOL · SUBSTRATE DEVELOPER HUB The Subkey Tool. Subkey is a public key cryptographic utility that is developed within Substrate itself . Its main feature is generating and inspecting key pairs, currently supporting these scheme: All keys in Substrate based networks ( like polkadot ) use the SS58 address encoding format that is the primary user-facing way to interact withkeys.

This conversion can fail if the structure of the Value does not match the structure expected by T, for example if T is a struct type but the Value contains something other than a JSON map. It can also fail if the structure is correct but T's implementation of Deserialize decides that something is wrong with the data, for example required struct fields are missing from the JSON map or SERDE_JSON::TO_STRING Serialize the given data structure as a String of JSON. Errors. Serialization can fail if T's implementation of Serialize decides to fail, or if T contains a map with non-string keys.T's implementation of Serialize decides to fail, or if T contains a map with non-stringkeys.
