Study Notes
- Ethereum is community-run technology
- Ethereum powers the cryptocurrency ether (ETH)
- Ethereum is behind thousands of decentralized applications
What is Ethereum?
- Ethereum calls itself a fairer financial system, the internet of assets, an open internet, and a new frontier for development
- Ethereum is defined as a decentralized blockchain network powered by the Ether token
- Ethereum enables users to make transactions, earn interest on their holdings through staking, and use and store non-fungible tokens (NFTs)
- With Ethereum users can trade cryptocurrencies, play games, and use social media
- Ethereum is essentially one decentralized system
- It runs a computer called the Ethereum Virtual Machine (EVM)
- Each node holds a copy of that computer
- Any interactions must be verified so everyone can update their copy
Ethereum Components
- Smart Contracts execute automatically when certain parameters are met
- Dapps are apps used on the Ethereum network
- Validators confirm all on-chain transactions to allow the Ethereum network to function
History
- Vitalik Buterin, a Canadian computer programmer, is famous for co-founding the network
- Buterin became involved with cryptocurrency early on
- Vitalik Buterin co-founded Bitcoin Magazine in 2011
- In 2015, Buterin deployed the Ethereum blockchain with Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin
- Ethereum is a decentralized mining network and software development platform rolled into one
Significance
- Ethereum is labelled the internet's next step by COINDESK
- If centralized platforms like Apple's App Store represent Web 2.0, then Ethereum symbolizes Web 3.0
- The network supports decentralized applications (DApps), decentralized finance (DeFi), and decentralized exchanges (DEXs)
How it Works
- Each transaction has a fee called “gas”
- Gas is paid by the user initiating a transaction
- The fee is paid to the node as an incentive for validating transactions and ensuring network security
- Gas serves as a limit
- Gas restricts the number of actions a user can make per transaction
- Gas prevents network spam
More About Gas
- Ether is the currency and fuel of the Ethereum network
- Ether's utility value as a crypto-fuel translates to “gas”
- Gas is a core part of all network requests where senders pay for computing resources consumed. (Compensation)
- The cost of fulfilling a request is: Cost = (Volume + Complexity) X Current Gas Price
Ethereum Uses
- Serves as the biggest platform for decentralized finance (DeFi)
- Decentralized Applications (DApps) contribute to the Ethereum network as more and more are used
- Successful DApps bring more awareness to the platform
- For NFTs, it is used to hold proof of ownership and secure forms of storage
- Social media apps are uncensorable
- Ethereum enables users to tip each other for content
- Users can invest in assets, play to grow them, and then sell for a profit playing games
- Creators of prediction platforms reward correct forecasts
- Freelance platforms do not take a huge cut from each payment
Advantages
- It lacks censorship compared to Facebook
- Community censors based social media platforms can only censor if the community votes to do it
- User can discuss different viewpoints because the community decides what should and shouldn't be said
- Ethereum's needs bad actors to control 51% of the network to make network changes
- It employs smart contracts to automate steps taken by central authorities on the traditional web
Ethereum Disadvantages
- High transaction fees leads to scalability issues
- Decentralization hinders quick transaction speeds
- A central entity manages everything
- The Ethereum platform is expensive to develop and challenging to use for unfamiliar users
- Some platforms require specific wallets, meaning Ethereum (ETH) must be moved to the required wallet
- Using Ethereum needs streamlining
Position in Crypto
- Bitcoin (BTC) and Ethereum (ETH) are the leaders of their domains
- Most widely recognized cryptocurrencies
- Most valuable in terms of total market capitalization
- Decentralized cryptocurrencies
- Both assets are stored in digital wallets
- Assets are sold on cryptocurrency exchanges
- Platforms are based on a publicly visible distributed ledger (blockchain)
Bitcoin vs. Ethereum
- Ethereum is a platform to run applications and smart contracts whereas Bitcoin is a currency
- Consensus Mechanism is Proof of Work (POW) vs. Proof of Stake (POS)
- Transaction Capacity: 7-10/second vs 100k/second (intended)
- Block Time (time to mine a transaction block) is 10 minutes vs. 10-20 seconds
- BTC is the most mainstream cryptocurrency in the space
- Ethereum is striving to be the next phase in the evolution of the Internet
- It may automate many processes that require intermediaries such as an app store or working with fund managers
- All Ethereum-based tokens are technically interoperable
- Bitcoin's network is exclusively for Bitcoin
What is ether (ETH)?
- Ethereum is the blockchain
- ETH is Ethereum's built-in cryptocurrency and primary asset
Eth and Fees
- ETH powers Ethereum by fueling and securing it
- When you send ETH or use an Ethereum application, you pay a fee in ETH to use the Ethereum network
What is Gwei?
- It's the denomination of ether most widely used
- Gwei is the most used unit of ether
- 1 ETH = 1 billion Gwei, or 1 ETH = 1018 Wei
- Used to pay for the computational power required for transactions
- The standard transaction fee is 21,000 gwei and they increase proportionately to the underlying complexity of the transaction
How to Buy ETH
- Choose a cryptocurrency exchange
- Fund your account
- Order Ethereum
- Store your Ethereum
Essential Ethereum Terms & Expressions
- Smart contracts digitize agreements by turning the terms of an agreement into computer code that automatically executes when the contract terms are me
- Decentralized applications (Dapps) include smart contracts & a web user interface, and are built on top of open, decentralized, peer-to-peer infrastructure services
- Ethereum Virtual Machine (EVM) enables anyone to run any program, and allows for creation of blockchain applications
- Tokens are tradable virtual goods defined in smart contracts on the Ethereum blockchain, and are interchangeable, unlike NFTs
- Non-Fungible Tokens (NFTs) are also known as a "deed," and an ERC-721 proposal
- It's a token standard introduced by the ERC-721 proposal, and can represent ownership of digital or physical assets
- ERC-20 standard allows developers to build token applications interoperable with other products and services
- Decentralized Autonomous Organizations (DAOs) are companies or other organizations that operate without hierarchical management
- Gas is a virtual fuel used in Ethereum to execute smart contracts
- Wallets are software containing private keys, and is used to access and control Ethereum and interact with smart contracts
- Oracles are a bridge between the blockchain and the real world operating as on-chain APIs that can be queried for information and used in smart contracts
- Decentralized Exchanges (DEXs) are a type of dApp that lets you swap tokens with peers on the network
