How Substrate Frame v2 different from Frame v1

Reading Time: 3 minutes Blockchain is a specific type of database. It differs from a typical database in the way it stores information. Blockchains store data in blocks that are then chained together. Blockchain has changed how we perceive problems. It has brought tons of benefits. Blockchain technology solves key issues like trust in a network. Blockchain technology utilizes advanced security compared to other platforms or record-keeping systems. By using Continue Reading

Substrate’s Smart Contracts vs. Runtime Development

Reading Time: 3 minutes This article gives a brief overview of the different ways to implement smart contracts for Substrate-based blockchains. It also aims to provide insight on reasons for choosing smart contract development over runtime development for your on-chain logic and business development. Substrate provides two smart contract virtual machines which can be added to your runtime. Each come with additional tools to ease development depending on your Continue Reading

BABE – Consensus Algorithm and How to Implement it

Reading Time: 3 minutes What are consensus algorithms? Consensus means finding a way so people on a blockchain can reach a common agreement about the present state of the distributed ledger. Consensus algorithms make sure that all the nodes on the blockchain can reach a consensus over some computation. As a result, It will bring reliability to the blockchain network and establish trust among all the nodes in a Continue Reading

Create runtime API of Substrate based 2D barcode scanner Pallet for Querying

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

Integrate Substrate based 2D barcode scanner Pallet in your Substrate Runtime

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
