What is Ethereum? | The Ultimate Beginners’ Guide

With the second largest market cap in the cryptocurrency world, Ethereum has drawn a lot of attention from investors and crypto enthusiasts alike. This relatively new cryptocurrency not only presents a significant change to the status quo, it also allows for the quick development and deployment of new applications. Ethereum essentially enables dozens of new and extremely innovative cryptocurrencies to exist. While Ethereum’s utility is obvious to programmers and the tech world at large,...

Understanding the concept of Private Key, Public Key and Address in Ethereum Blockchain

Before we get deeper into the concept of Ethereum Blockchain, it is important to understand how Public Key, Private Key and Address are generated. To make this easier for beginners, I am trying to explain the technical concept with an example. Ethereum key generation is based on elliptical curve ecp256k1. Eliptical curve (EC) is intense mathematics, and there are a lot of great articles on internet covering deep details of elliptical curve. There are standard...

Certificate on IPFS and Ethereum

We are going through a very exciting phase of technological transformation. Blockchain community is re-designing a lot of existing use cases and trying to solve a lot of unsolved use cases with the help of decentralized, peer-to-peer technology. Certificate generation and verification is one of the uses cases which is being attempted to be gracefully handled by blockchain. Here is one of the possible approach using Ethereum and IPFS. Step 1: Every certificate issuer is...

Hyperledger Blockchain vs. Ethereum Blockchain

Hyperledger – a Linux foundation project: Hyperledger, a Linux Foundation project, is an open source community to help advance technology and thought leadership. It was originated from IT majors like IBM and Intel who saw the benefits of Blockchain technology in Bitcoin. They didn’t wanted it to be used for financial transactions, so, forced them to develop their own software. Since doing it separately would be a waste of resources, these companies centralized their software...

INTRODUCTION TO IPFS

Distributed. Hypermedia. Content-addressable. Identities. Permanent Web. These are a few terms that seem to get thrown around a lot these days when people talk about upcoming web technologies. If you too are confused like the majority of us, then here is the guide that will take you through each of these terms and explain how and why we need them. Let’s explore… IPFS IPFS stands for Inter Planetary File System. What is IPFS? It...

zk-SNARKS in Ethereum

zk-SNARKS It is one of the hottest topics in cryptography over the last year. One major reason behind it being hot is Zcash launch. Zcash is a cryptocurrency, whose flagship feature is that it integrated zk-SNARKS (Zero Knowledge Succinct Non-Interactive Argument of Knowledge). General principles: As the title suggests, this is ultimate in privacy. It is about proving thing about encrypted data without revealing anything about the data except for the claim that you are...

Concept of Merkle Tree in Ethereum

Merkle Tree Merkle Tree also known as 'hash tree' is a data structure in cryptography in which each leaf node is a hash of a block of data, and each non-leaf node is a hash of its child nodes. In the most general sense, Merkle tree (named after Ralph Merkle who patented it in 1979) is a way of hashing many “chunks” of data together which relies on splitting the chunks into nodes, where each...

Running Ethereum testnet using Geth

In this post, we are going to setup a testnet of ethereum using Geth. Testnet is use full in many cases like when we want to do some transactions on ethereum network without spending actual ethers. we will still need ethers to do transactions on testnet but generating ether on test is very easy and can be done on your laptop and may be within in 10 minutes we will have enough ethers to do...
