Bitcoin uses mining machines to keep the ledger, while Ethereum no longer does. What’s the difference?
Definition: Under Ethereum’s proof of stake, 12 seconds is one slot, and at most one block can be produced per slot.
The logic behind it: Proof of stake uses staked assets as collateral. Validators who act maliciously have some of their stake slashed, and those who stay offline for a long time also have part of their balance deducted.
A quick look: $BTC Current price: 75664, 24h: -1.01%.
Make sure you understand the principles before taking action. Don’t place orders based on gut feeling.
