How to Generate Random Numbers on Ethereum Using VRF
Random numbers and Blockchains have always been in disagreement. Until now, a verifiably random function has never existed on the Blockchain.

Ethereum Interview Questions – Part 1
Who is the founder of Ethereum? Vitalik Buterin What is the average block time in Ethereum? 14–20 seconds What is the average block size in Ethereum? 20–30KB What is the average number of transactions per second? 17–20 Is Ethereum a…
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.
