Frequently Asked Questions
What is the difference between Ethereum and Bitcoin?
While both are cryptocurrencies, Ethereum's blockchain can execute complex code (smart contracts), making it more than just a digital currency platform.
How long does it take to set up an Ethereum node?
Depending on your hardware and network speed, initial synchronization can take anywhere from a few hours to several days.
Is Ethereum mining still profitable?
With Ethereum's transition to Proof-of-Stake, traditional mining is no longer possible. Validators now secure the network through staking.
What programming languages are used in Ethereum development?
Solidity is the primary language for smart contracts, while JavaScript, Python, and Go are commonly used for DApp development.
How much does it cost to deploy a smart contract?
Costs vary based on contract complexity, measured in "gas." Simple contracts might cost $10-$50, while complex ones can reach hundreds of dollars.
Can I test Ethereum applications without spending real money?
Yes! Testnets like Goerli and Sepolia provide free test Ether for development purposes.
