Plain English

Proof of Stake is a consensus mechanism where validators lock up the native asset as collateral and are selected to propose blocks based on stake size and randomness. Ethereum, Solana, and most modern chains use it.

How it actually works

Validators stake the network’s token as a security deposit. The protocol pseudo-randomly selects validators to propose blocks. Honest validators earn rewards. Dishonest validators are “slashed” — they lose part of their staked deposit. Energy consumption is minimal compared to proof-of-work because there is no computational race.

What it means for you

For Ethereum and Solana stakers, proof-of-stake is what makes the staking yield possible. The trade-off versus proof-of-work is technical — different security assumptions, different attack surfaces, different economic models.

How ARCrypto teaches this

We walk through the practical and security differences between PoS and PoW, why Ethereum switched in 2022, and what it means for long-term holders.
