~dwulf So much of my writing was discussing the core ideas of para-chains for the Polkadot ecosystem. Running these is only one part of the mastery of Polkadot, but building them, is quite another. In the last 3 chains I have worked with 2 with Substrate, 1 with Atom’s IBC…

~dwulf Beckon the call for the Polkadot Blockchain Academy Got the email today for the test to be qualified for the Polkadot Blockchain Academy in Berkely, CA from July 10th to August 10th, 1 month of the “boot camp”. …

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…

~dwulf Week 1 So this is my first day of this course, I decided to put my notes on Medium and on-line, so I can illustrate what I am learning. …

Composable’s vision for Picasso is that it becomes an environment where the community is able to add various features and products directly into the runtime of the chain. That is, being able to be the chain in the Kusama and Polkadot ecosystems that allow for the integration of pallets into…

Substrate Monthly — Ecosystem Technical Newsletter, produced by OneBlock+, summarizes the technical progress of the top projects in various areas in the Polkadot ecosystem each month to get the community updated on the status of the ecosystem. Areas include DeFi, infrastructure, smart contracts, privacy, GameFi, etc. …

Taking a look at blockchain languages based on and built on Rust. Not long ago I started programming in Rust for the fun of it. …

Exploring Ink syntax and Rust concepts with a Non-Fungible Token smart contract — Ink is a smart contract language specifically for use with a Substrate-based blockchain. This talk will delve into a non-fungible token contract written in Ink; we will visit implementations of the minting, transferring and approval functions, and explain the syntax along the way. …

A Brief Overview Of The Substrate — Today, we’ll go over the Substrate, the fastest way to build blockchains. This article will provide a brief overview of the Substrate. So let's go ahead. The Substrate is an open-source framework that allows teams to quickly build highly customized blockchains. The developers gain free access to a wide codebase…

Polkadot’s first batch of 5 parachains was successfully launched on December 18th, marking Polkadot’s entry into the “parachain era”. What everyone is looking forward to seeing is what kind of innovation and network effects the cross-chain interaction between parachains will bring. In this article, we will take a look at…

By Sumi Maria Abraham, Research & Training Engineer, Kerala Blockchain Academy Hi Everyone, Didn’t we promise a detailed blog on Polkadot last week? Here is the technical impression of Polkadot Blockchain giving you a much-magnified outlook of its architecture and working philosophy. …

One of the key features of Polkadot “version 1.0” is to let its otherwise isolated parachains send messages between each other with guarantees and in a secure and trust-free manner. A message refers to data coming from outside of the receiving chain, and implies and requires that the chain acts…

Summary The polkadot is very compatible with the multi-chain. Actually, we can’t have massively transactions around the world on one chain like the Bitcoin and Ethereum network. The polkadot depends on substrate which is opensource, module and framework to build the blockchain network. The substrate depends on the Rust programming language…
