What is Ethereum (ETH)?
Ethereum (ETH) is a decentralized blockchain platform that enables smart contracts and decentralized applications (dApps). Its native cryptocurrency, Ether (ETH), is used to power transactions and computational services on the network.
Key Features:
- Smart Contracts: Self-executing contracts with predefined rules.
- ERC-20 Tokens: Standard for creating custom tokens on Ethereum (e.g., USDT_ERC20).
- Decentralized: Operates without intermediaries, secured by a global network of nodes.
How Ethereum Mining Works
Ethereum mining involves validating transactions and adding them to the blockchain through Proof of Work (PoW). Miners solve complex mathematical puzzles to earn ETH rewards.
Mining Steps:
- Transaction Validation: Miners verify pending transactions.
- Block Creation: Valid transactions are grouped into blocks.
- Proof of Work: Miners compete to solve cryptographic puzzles.
- Reward: The first miner to solve the puzzle receives 5 ETH (as of current block reward).
⚠️ Note: Ethereum plans to transition to Proof of Stake (PoS), eliminating mining in favor of staking ETH.
Creating and Managing ETH Tokens
ERC-20 Tokens
ERC-20 is a standard for creating fungible tokens on Ethereum (e.g., USDT_ERC20, ZTH).
Steps to Create a Token:
- Define Token Parameters: Name, symbol, total supply.
- Write Smart Contract: Use Solidity (Ethereum’s programming language).
- Deploy Contract: Pay gas fees in ETH to publish on Ethereum.

ETH Transactions: Sending and Receiving
Receiving ETH/ERC-20 Tokens
- Use your Ethereum address (same for ETH and all ERC-20 tokens).
- Ensure the sender selects the correct token type (e.g., USDT_ERC20).
Sending ETH/ERC-20 Tokens
- Unlock Wallet: Upload keystore file or enter private key.
- Enter Recipient Address: Double-check accuracy.
- Select Token: Choose ETH or specific ERC-20 token.
- Pay Gas Fees: Requires ETH for transaction costs.
⚠️ Gas Tip: Maintain >0.0035 ETH in your wallet for smooth transactions.
FAQs
1. What’s the difference between ETH and ERC-20 tokens?
- ETH is Ethereum’s native currency, while ERC-20 tokens are custom assets built on Ethereum (e.g., USDT_ERC20).
2. How do I check my ETH balance?
- Use blockchain explorers like Etherscan or your wallet interface.
3. Why is my ERC-20 transaction failing?
- Likely due to insufficient ETH for gas fees. Fund your wallet with ETH to cover costs.
4. Can I mine ETH with a regular PC?
- Not profitably. Mining now requires GPUs or ASICs due to high difficulty.
5. When will Ethereum switch to Proof of Stake?
- Expected in 2023 (Ethereum 2.0 upgrade).
