MEGA-THREAD: How to talk [#Ethereum](https://twitter.com/hashtag/Ethereum?src=hashtag_click) like a Pro.

A Thread

1/ What is Ethereum?

A blockchain with a built-in Turing-complete programming language, allowing anyone to write smart contracts and decentralized applications (dApps) where they create their own arbitrary rules for ownership, transaction formats and state transition functions.

2/ What is Ether?

Ether (ETH) is the currency of the Ethereum network. Every time you send ETH or use an Ethereum application, you pay a small ETH fee (gas fee). By requiring a fee for every computation executed on the network, bad actors are prevented from spamming the network

3/ Currently, ETH is mined using the proof of work consensus mechanism, the same process as Bitcoin.

4/ Let’s use Uber as an real-world example:

You can think of $ETH as the fuel needed to power the car (Ethereum) to make the trip (complete the transaction), and the #Uber driver is incentivized by the driver fee (gas fee) to make the trip.

5/ Difference:

The major difference between #Ethereum and #Bitcoin is their use cases.

The main purpose of Bitcoin is for peer-to-peer payments, whereas Ethereum aims to be a distributed world computer where you can build on top of it.

6/ Crypto Wallets: For Ethereum

Ethereum wallets are applications that let you interact with your #Ethereum account. Your wallet(s) allows you to do the following: manage not only your funds, but also your collectibles (#NFTs) and membership to DAOs.

7/ Types of Wallets

i. Non-custodial wallet: allows users to hold and own their private key while having full control of their funds.

*   Hardware Wallets: similar to a flash drive that is offline (Ledger, Trezor)
    
*   Web-Based & Mobile Wallets: MetaMask
    
*   Desktop Wallet: Exodus
    
    8/
    

ii. Custodial wallet: It’s very likely that the first time you purchase crypto, it will end up in a custodial exchange crypto wallet. In this case, the exchange is your custodian, which holds your keys and is tasked with securely storing your funds (#Coinbase, #Binance)

9/ What You Can Do with Ethereum: #DApps

Once you set up your #Ethereum wallet, you can use decentralized applications (dApps). Dapps are decentralized apps that are built on a decentralized network that combines a smart contract + a frontend user interface. 10/ Key features of #DApps:

*   Open-source
    
*   Public data and records
    
*   Uses a cryptographic token to help keep the network secure
    
    11/ What is Smart contract?
    

You can think of it as the back-end of dapps. Once the predetermined conditions of the contract are met, the transaction is automatically completed and recorded on the blockchain.

12/ Smart contracts can define rules, like a regular contract, and automatically enforce them via the code. Smart contracts cannot be deleted by default, and interactions with them are irreversible. (ie: Smart contracts on Ethereum are typically written in Solidity or Vyper.) 13/ Common categories of DApps:

*   Finance
    
*   Art and collectibles
    
*   Gaming
    
*   Technology 14/ Use-Case of Ethereum:
    
*   DeFi (Decentralized Finance)
    
*   NFTs & Collectibles
    
*   Decentralized Autonomous Organizations (DAOs)
