Question 1

What is Ethereum in simple terms?

Accepted Answer

Ethereum is a decentralized, open-source blockchain that enables developers to build and deploy smart contracts and decentralized applications (dApps). While Bitcoin is primarily digital money, Ethereum is programmable money -- a global computer that anyone can use without permission.

Question 2

What is the difference between Ethereum and Bitcoin?

Accepted Answer

Bitcoin is designed primarily as a store of value and peer-to-peer payment system with a fixed supply of 21 million coins. Ethereum is a programmable platform that supports smart contracts, DeFi, NFTs, and decentralized applications. ETH does not have a hard cap, but its issuance is offset by a burn mechanism (EIP-1559) that can make it deflationary during high network usage.

Question 3

How much can I earn staking Ethereum?

Accepted Answer

As of 2026, native Ethereum staking yields approximately 3-4% APY. You need 32 ETH to run a solo validator, but liquid staking protocols like Lido (stETH) or Rocket Pool (rETH) allow you to stake any amount. Restaking through protocols like EigenLayer can boost yields further, though with additional risk.

Question 4

What is proto-danksharding (EIP-4844)?

Accepted Answer

EIP-4844 introduced 'blob transactions' that dramatically reduced data costs for Layer 2 rollups. Instead of posting all transaction data directly to Ethereum's execution layer, rollups can now use temporary data blobs that are much cheaper, reducing L2 fees by up to 90-100x.

Question 5

Is Ethereum a good investment in 2026?

Accepted Answer

Ethereum has the largest smart contract ecosystem, the deepest DeFi liquidity, and strong institutional interest through spot ETH ETFs approved in 2024. However, all crypto investments carry significant risk. Evaluate your risk tolerance, diversify your portfolio, and never invest more than you can afford to lose.
