What is ethereum’s capability?
support programming - smart contracts and tokens, platform for decentralized applications
What is gas in Ethereum? How is it priced?
Gas is the computational work required for transactions, priced in Gwei (small unit of ETH)
What happens to the gas fees collected on the Ethereum network?
A portion of the fees is "burned," reducing the total supply of ETH and controlling inflation
How much ETH must be staked to become a validator in Ethereum's Proof of Stake?
32 ETH is required to participate as a validator.
How often does Ethereum select validators and approvers in the PoS system?
Every 32 blocks, one validator is chosen to publish a block.
And 128 stakers are selected to evaluate it.
Maximum gas limit for a block in Ethereum's PoS
Each block is capped at 15 million gas
What can happen if a stake publishes an invalid block (unavailable staker) in Ethereum’s PoS?
They may incur a fine which is deducted from their staked 32 ETH
Why is Ethereum's Proof of Stake more energy-efficient than Proof of Work?
PoS does not require solving complex computational puzzles, avoiding high energy consumption.
