FAQ About Ethereum (ETH)

• What are the main applications of Ethereum?

  Ethereum supports a wide range of decentralized applications (dApps) across several categories.
  
  1. Financial applications (DeFi): Lending platforms, stablecoins, derivatives, decentralized exchanges (DEXs), and tokenized assets enable users to manage funds without relying on banks or intermediaries.
  
  2. Semi-financial applications: These combine financial and non-financial elements, such as automated bounties for problem-solving or prediction markets.
  
  3. Non-financial applications: Tools like decentralized voting systems, identity verification, and community-led governance platforms operate without financial functions.
  
  Thanks to smart contracts, these applications run autonomously on the Ethereum blockchain, offering transparency, automation, and trustless execution.

• What are the further applications of Ethereum?

  Beyond finance and basic decentralized applications (dApps), Ethereum supports advanced use cases across multiple industries thanks to its flexible smart contract functionality. Key applications include:
  
  1.Smart savings wallets: Wallets with customizable rules for withdrawals, shared access, and built-in safeguards to protect personal assets.
  
  2. Decentralized insurance: Smart contracts that automatically execute payouts based on real-world events, such as weather, enabling crop or disaster insurance without intermediaries.
  
  3. Trustless data feeds (Oracles): Ethereum can host decentralized oracles that provide reliable data, like ETH/USD prices, for use in financial contracts, prediction markets, and other applications.
  
  4. Smart multisignature escrow: Wallets with multiple levels of access for secure group fund management or business treasury solutions.
  
  5. Decentralized cloud computing: Community-based computing networks that support scientific research or simultaneous computational tasks.
  
  6. Peer-to-peer gambling: Transparent, low-fee gambling platforms that operate without traditional betting operators.
  
  7. Prediction markets and governance: Platforms for betting on real-world outcomes that can also inform governance decisions based on predicted results.
  
  Ethereum’s programmability allows developers to create systems that are decentralized, automated, and often more secure than traditional software solutions.

• What does Ethereum's scalability mean?

  Ethereum’s scalability refers to its ability to handle more transactions and applications without slowing down or becoming too expensive. Like Bitcoin, every transaction is processed by all nodes, which can limit throughput and sometimes cause network congestion and high gas fees.
  
  As demand grows, especially with many decentralized applications (dApps) running on Ethereum, scalability becomes important. Without improvements, the network could become centralized, as only large operators might be able to store and verify the entire blockchain.
  
  To address this, Ethereum is using solutions such as Layer 2 rollups, sharding, and stateless clients. These technologies aim to increase transaction speed, reduce storage needs, and keep the network secure and decentralized as usage grows.

• What makes Ethereum unique?

  Ethereum is the first blockchain to introduce smart contracts, which are self-executing programs that run without intermediaries. These contracts allow trustless transactions and decentralized applications (dApps), turning blockchain from a system for value transfer into a platform for programmable finance and automation.
  
  Ethereum also supports thousands of ERC-20 tokens, enabling other cryptocurrencies to be created on its network. Many well-known digital assets, including USDT, LINK, and BNB, started as Ethereum-based tokens. Combined with its decentralized structure and security, Ethereum powers DeFi, NFTs, and Play-to-Earn gaming applications.

• How is Ethereum different from Bitcoin?

  Bitcoin is mainly a decentralized digital currency used for peer-to-peer value transfer. Ethereum, by contrast, is a decentralized platform. It is a programmable blockchain that lets developers create and run smart contracts and decentralized applications (dApps).
  
  Think of Bitcoin as a single application for payments, while Ethereum is a platform for building many different applications.

• How many Ether coins are there in circulation?

  Unlike Bitcoin, Ethereum does not have a fixed supply. There are currently over 120 million ETH in circulation, and this number changes over time based on network activity and upgrades.
  
  With the shift to Proof of Stake and the Ethereum 2.0 upgrade, Ether issuance has slowed. Features like EIP-1559 burn a portion of transaction fees, permanently removing them from circulation. This supply model helps balance inflation and demand over time.

• What is Ethereum 2.0

  Ethereum 2.0 is the network upgrade that transitions Ethereum from Proof-of-Work (PoW) to Proof-of-Stake (PoS). This update is part of Ethereum's plan to improve scalability, security, and sustainability.
  
  Ethereum 2.0 introduces sharding, which splits the network into smaller chains to increase transaction capacity. The current Ethereum chain will become the Beacon Chain, acting as a settlement layer for smart contract interactions on other chains.
  
  To clarify the network structure, the Ethereum Foundation rebranded Ethereum 1.0 as the execution layer and Ethereum 2.0 as the consensus layer. Recent tests, including the mainnet shadow fork, show that the network is approaching the final stages of this transition.

• What is the difference between Ethereum and Ethereum 2.0 (The Merge)?

  The original Ethereum network used a Proof-of-Work (PoW) consensus mechanism, similar to Bitcoin. Ethereum 2.0 refers to a series of upgrades, the most important being The Merge, which switched the network to Proof-of-Stake (PoS).
  This change reduced Ethereum's energy use by over 99%, improved network security, and created the foundation for future scalability upgrades.

• What is the Ethereum Shanghai upgrade?

  The Ethereum Shanghai upgrade allows Ether stakers on the Beacon Chain to unstake their Ether and withdraw rewards. After The Merge, Ethereum moved from Proof-of-Work (PoW) to Proof-of-Stake (PoS), with validators staking 32 ETH to secure the network. Until Shanghai, staked Ether and rewards could not be withdrawn.
  
  Also called Shapella, the upgrade is a hard fork that implements five EIPs, with EIP-4895 enabling withdrawals. Shanghai refers to the execution layer, while Capella refers to the consensus layer.
  
  Testnets successfully executed the upgrade: Zhejiang on February 7, 2023, Sepolia on February 28, 2023, and Goerli on March 15, 2023. After the mainnet upgrade, expected in March 2023, over 17.5 million ETH became available for withdrawal.

• How does Ethereum's proof-of-stake (PoS) consensus work?

  In Proof-of-Stake (PoS), validators are chosen to create new blocks and verify transactions based on the amount of Ether they stake as collateral. Validators are encouraged to act honestly because dishonest behavior can lead to their staked Ether being slashed or destroyed.
  
  This system makes Ethereum more secure, uses less energy, and is easier to participate in compared to the previous Proof-of-Work system.

• How to mine Ethereum?

  Mining Ethereum involves using computer hardware to solve mathematical puzzles to validate transactions on the network. Here’s how you can mine Ethereum:
  
  1. Get the right hardware: You need a computer with a graphics processing unit (GPU). A more powerful GPU can solve puzzles faster and earn more Ether.
  
  2. Download mining software: Choose software compatible with your hardware, such as Claymore, Ethminer, or PhoenixMiner, and install it.
  
  3. Create an Ethereum wallet: Set up a wallet to store the Ether you mine. Options include online wallets, hardware wallets, and software wallets.
  
  4. Join a mining pool: Mining alone can be difficult. Joining a pool lets you combine efforts with other miners, with rewards distributed based on each member’s contribution.
  
  5. Configure your software: Enter the mining pool’s details, your wallet address, and your hardware information into the software.
  
  6. Start mining: Run the software to solve puzzles. Successfully solving a puzzle earns you Ether.
  
  7. Monitor progress: Track your mining statistics and payouts through the pool’s website or the software to ensure your mining is effective.
  
  Mining Ethereum uses a lot of energy and may not always be profitable, especially as difficulty rises. Consider electricity costs and hardware maintenance before deciding to mine.
