Some of the topics are going to cover Whats is Ethereum, Technology behind the Ethereum, Ethereum’s applications, how to earn money using Ethereum and complete guide to buying Ethereum worldwide.

Ethereum world of crypto

What is Ethereum?

Ethereum is open-source, distributed blockchain-based smart contract programming environment where developers can build decentralized applications top of the Ethereum blockchain. Ethereum is digital currency behalf of smart contract facility where the currency is Ether. Ethereum was founded by Vitalic Buterin who is a programmer and former contributor of the BitcoinMagazine.

History-Special milestones

There are a lot of updates and Events happened in Ethereums history, These are the major events and updates,

  • In February 2014, Ethereum foundation was born.
  • In May 2015, Testnet launched [Olympic]
  • In 30th July 2015, Mainnet launched [Frontier ] and Genesis block was created where the genesis block means first created a block of any blockchain.
  • In April 2016, DAO [Decentralized Autonomous Organization] launched and 150M raised where the DAO is a smart contract that describes the organization.
  • In June 2016, Bug in DAO code exposed and hacked by unknown. To refund 50M immediately decided to hard-fork the Ethereum blockchain [Hardfork is splitting the old blockchain and eventually creating new blockchain by Majority miners voting]. Someone stayed the old Ethereum chain which is called Ethereum classic.
  • In January 2018, Ethereum hit all the time high which was 1390$
  • Next Major Update has to come which Serenity

What is Ethereum smart contract?

Normal contracts are agreements of the two parties or more which written on paper and enforced by law. A smart contract is self-executed computer coding technique intends to digitally facilitate, verify, or enforce the traditional contracts.  First Nick Zhabo introduce the smart contract concept and, later Vitalic Buterin integrates into the Ethereum blockchain.

Advantages of smart contract

  1. No intermediaries – Normally traditional contracts rely on third parties likes lawyer and smart contract depends on the blockchain
  2. Speed – Typically more speed than traditional contracts because it is run by written codes. No paper works
  3. Transparency – Contracts open to the relevant parties and There are no doubts.
  4. Storage and Backup – All the copies of the contracts spread over the computer nodes and every transaction records on the blockchain.

Smart contract applications run on Ethereum blockchain help of computing power is provided by Ehtereum nodes spread all over the world. Nodes can introduce as decentralized world computer where contract transactions distributed publicly across these nodes and recorded in Ethereums blockchain. These nodes get paid from the native currency Ether(Eth) for computing power provided.

Ethereum typical terms

There are many terms used in the Ethereum platform where explain popular terms.

What is Ether, gas price, and gas limit?

Ether(Eth) is the native currency in Ethereum blockchain where Ether valued unit ( digital asset) used to pay out for computer power provided to the network.

Gas: When the transaction happens in Ethereum blockchain, Computer hash power need to process a transaction where the hash power required, is determined by the gas unit.

Gas Price: the Gas price is amount pay (amount of Eth ) per unit of gas for a particular transaction where high gas price faster transactions. ( Fee for transaction = Gas price * Gas limit) Gas limit: Maximum amount willing to pay for a particular transaction fee.

Whats Wei and Gwei?

Wei and Gwei also, a subunit of ether which is used to indicate transactions fees because that is very small. b[ 1Wei = 10^ -18 Eth ] [ 1Gwei = 10^ -9 ]

ERC -20 tokens: That is created in Ethereum blockchain when developing a new Dapp project. These tokens create, issues according to a set of standards provided by Ethereum. This token also traded in cryptocurrency exchanges.

Ethereum decentralized applications [Dapps]

Decentralized application[ Dapps] is an application that is run and build on Ethereum blockchain. When creating Dapp, we can create token to represent the Dapp brand, a token can be used to fundraise for project, used for the platform as a utility token. The Dapp tokens traded on exchanges and we can invest in Dapp projects that have the potential to grow in the future.

As example BAT token price in ICO stage was $0.035 and June 2019 price is near 0.25$. In case total gain is 7X within few years.

A typical process to build decentralized applications

  1. If you have an innovative idea write a white paper
  2. Establishing the startup
  3. Marketing the project to attract investors, Most startups hold bounty program to promote the project among the crypto community
  4. Hold ICO to raised fund for development and other expenditure

What is Ethereum 2.0

Eth 2.0 update will huge for ethereum blockchain because It will solve a lot of issues arising in current ethereum blockchain then Ethereum will be faster, efficient and economical. Also, this major update called “Serenity” update.

Eth 2.0 major updates

01. Proof of stake – Casper

Next major update is converting proof of work( Ethereum used bitcoin transaction validation mechanism-miners ) to proof of stake(validator nodes locking up ethereum- stakers) where Staking users will earn the interest with Eth. Staking is more economical than mining.

02. Sharding

This is major integration into the Ethereum blockchain which is partitioning large chains into smaller parts which bring faster and efficient transaction. Eventually, the network becomes more scalable.

03.EWASM- Ethereum virtual machine improvements

EVM is a kind of code running environment in Ethereum where all nodes connected. EWASM will increase code execution speeds and time.


Which is an extra layer or chain to handle a huge amount of transaction? It is Etherem’s lightning network. (Lightning network is a second-layer solution for bitcoin for scalability solutions)

How to invest in Ethereum?

There are few methods to invest in Ethereum platform which are listed and explained.

01.Ethereum mining

Ethereum uses bitcoin mining concept to Validate Ethereum’s transactions. In this case, miners should provide computer hash power (GPU mostly used) to the Ehterum network. We can earn money for contributing hash power to Ethereum network. Cheap electricity is the main factor for profitable mining.


Most investors and retails buyers buy Ethereum at a lower price and then sell it at a higher price which is the most popular and easy way to invest in Ethereum.

03. EthereumTrading

As traditional assets, Ehtereum also, traded in so many exchanges. To get start cryptocurrency trading, you need to learn TA, FA  and Basic trading technique to get constant profit.[TA- Technical analysis, FA – Fundamental analysis]

Types of trading
