Prova de Participação (PoS)
Consenso de baixo consumo energético.
## Technical Deep Dive: The Merge and Security Models
### Ethereum's Gasper
Ethereum uses a combination of LMD-GHOST (fork choice rule) and Casper FFG (finality gadget). This ensures the network can continue producing blocks (Liveness) while eventually providing Economic Finality (Safety).
### Punishments and Incentives
- Attesting: Earning small rewards for confirming valid blocks.
- Proposing: Earning higher rewards for being selected to create a block.
- Slashing: Confiscating 1/32 to 100% of a validator's stake for equivocation (signing two different blocks at the same height).

Imagine a raffle where you get more tickets for every dollar you put into a savings account. You don't have to keep a loud, hot machine running—you just show that you have skin in the game, and the network picks someone to verify the next batch of transactions.
