RPC to call a Runtime API easily in Substrate

August 12, 2021August 12, 2021Rustparity, RPC, runtime api, Rust, Rust programming language, substrate

Reading Time: 4 minutes RPC or Remote Procedural Call in Substrate is a way to interact with a Substrate node. They can be used for checking storage values, submitting transactions or querying the current consensus authorities. Substrate is a next-generation framework for blockchain innovation. It comes with everything you need to build your blockchain. Substrate is a completely free and open-source project. It is built using Rust and WebAssembly. Rust Continue Reading

Reading Time: 2 minutes In my previous post Integrate Substrate based 2D barcode scanner Pallet in your Substrate Runtime, I explained how to integrate Substrate pallet in your runtime. Substrate runtime is its State Transition Function, which contains business logic of a Blockchain that determines how the state changes when a block is processed and defines its behaviour of the Blockchain. Substrate runtime can be accessed to outer node though an API, Continue Reading

Reading Time: 2 minutes In my previous post Substrate based 2D barcode scanner Pallet in Rust, I explained how to create Substrate pallet easily. A pallet, Also known as Runtime modules, contains the logic, which can modify the features and functionality of your blockchain’s state-transition function. A typical Substrate project consists of 4 components: NodeRuntimePalletsExecute in Docker The runtime is Substrate’s state transition function and is divided into separate Continue Reading

Substrate based 2D barcode scanner Pallet in Rust

November 9, 2020November 9, 2020RustBlockchain, parity, Rust, Rust programming language, substrate

Reading Time: 2 minutes As we know, Rust is one of the best programming languages for blockchain due to its highly-capable mechanism of handling mutable states. The fast, memory safe, and exclusively concurrent nature of this blockchain coding language makes it most suitable for developing real-world blockchains. I was looking for a Rust based blockchain framework and I found Substrate, which is developed by Parity technology and built in Continue Reading
