Sharding: The brain of Ethereum 2.0
In sharding, the history and the state of the whole Ethereum blockchain are divided into individual partitions called shards. Each shard will have its state and a history of transactions.

Beacon Chain: Heart of Ethereum 2.0
Beacon Chain is the heart of Ethereum 2.0. It is the base upon which the rest components like Shard, eWasm, and cross-link will be built.
It (PoS based chain) will run parallelly with the Mainnet (PoW based chain). Beacon chain is mainly made for the validators.
Proposing Future Ethereum Access Control
Dissecting current standards and proposing possible solutions for fully dynamic access control management in smart contracts Access control is a fundamental element to the security of software infrastructure. Enterprise applications need strict rules on who can do what, depending on…
Building an Ethereum Simulation Game – Part 4 – Training and Resting Players
Recap Part three saw the introduction of the last Smart Contract jigsaw piece being put into place, and from there, the beginnings of a rudimentary interface using React and Redux. I’ve added a few cool little features since then and got the interface…
Building An Ethereum Simulation Game – Part 3 – The Front End
Recap In part one I outlined the idea for a Tennis Manager simulation game on the Ethereum Blockchain. I created the ERC721 Token and the TrainableTennisPlayer contract which enables owners to increase their player stats by training or resting. Part…
Ethereum Name Service (ENS)- An Overview
ENS stands for Ethereum Name Service, which is a decentralized naming service built atop Ethereum.
Building An Ethereum Simulation Game – Part 1 – Inception
I recently wrote an article on ERC721 tokens. To demonstrate their use, I used the example of a Pokemon-like game. It got me thinking of some of the games I couldn’t get enough of as a kid. The hours I…
Building An Ethereum Simulation Game – Part 2 – Playing Tennis Matches
In part one, I outlined the idea for a Tennis Manager simulation game on the Ethereum Blockchain. I created the ERC721 Token and the TrainableTennisPlayer contract which enables owners to increase their player stats by training or resting.
Since that article, I’ve written some unit tests and made a few small changes to those contracts. Events have been added to TrainableTennisPlayer to emit when players are trained or rested. Some utility functions that were initially written in TrainableTennisPlayer have been moved to the TennisPlayerBase.
Ethereum Smart Contracts and the Oracle Problem
“Provable”, formerly known as “Oraclize”, is a service known as an ‘oracle’, built specifically to address this problem. An oracle acts as a relay by aggregating data from external sources such as random number generators, price tickers & computational engines. Once the data is collected, the oracle feeds it into a smart contract.

You sure must have heard of Ethreum. It is the second most popular and valuable cryptocurrency after Bitcoin based on market cap. Ethereum has been around since 2013 and has initiated the blockchain 2.0 revolution by introducing smart contracts. In this article, we will try to understand how Ethereum mining works.
