U nderstand that the Ethereum wallet is a gateway to decentralized apps on

the Ethereum blockchain. A comparison of accounts vs. wallet is done as;

also, GAS-Cost unit is described. The issue of rising ETH gas fees which

has led to the rise of Layer 2 protocols such as polygon, is discussed next.

K now what mining is and the steps involved for mining with an explanation

of a block, metadata of blocks, block size, block creation, and uncle block.

K now about ETH and explain the smart contract and the transaction rules.

Describe Decentralized App (dApp) and get an introduction to solidity

programming language.

Introducing Ethereum

Available in the public domain, the blockchain-based distributed ledger,

which features smart contract (scripting) functionality, is Ethereum. The

high availability of the Ethereum network can be leveraged by the

developers to build blockchain applications with their business’s logic,

which gets executed in a trustless environment.

Developers are enabled to build and deploy decentralized applications using

the open software platform, Ethereum, based on blockchain technology. To

pay for transaction fees and services, the application developers use Ether

on the Ethereum network as also it is used as a tradeable cryptocurrency.

The ownership of digital currency (bitcoins) is tracked by the Bitcoin

blockchain. Earning Ether, a crypto token fueling the network, is the focus

of miners, whereas running the program code of any dApp is the focus of

Ethereum blockchain.

Ethereum is a ledger technology used by companies to build new programs,

whereas Bitcoin is a currency that differentiates them.

In comparison, if Bitcoin was version 1.0, then Ethereum is version 2.0,

which can be used to build decentralized applications on top of it.

Programmer and writer V italik Buterin, a Russian– Canadian, is the co-

founder of Ethereum and co-founder of Bitcoin Magazine.

In addition to Buterin, Mihai Alisie, Anthony Di Iorio, and Charles

H oskinson co-founded Ethereum. Buterin also announced that he was

working with developers Dr. Gavin Wood and J oseph Lubin.
