Plain English

Ethereum is a programmable blockchain — meaning it is not just digital money, but a platform where other financial applications run. Smart contracts, stablecoins, decentralized exchanges, lending protocols, and tokenized assets all live on top of it. The native currency used to pay for computation is called Ether (ETH).

How it actually works

Ethereum uses proof-of-stake. Validators lock up ETH as collateral; the protocol selects them probabilistically to propose new blocks. Honest validators earn ETH rewards; dishonest ones lose part of their stake.

Every transaction or contract execution on Ethereum requires “gas” — a fee paid in ETH. This is what powers the entire on-chain economy.

What it means for you

If Bitcoin is digital gold, Ethereum is the on-chain financial highway. The vast majority of DeFi yield, lending, and tokenized real-world assets settle on Ethereum or its Layer-2 networks. For an HNW allocator, Ethereum is both a collateral asset and the operating layer for most yield strategies.

How ARCrypto teaches this

We walk you through Ethereum custody, staking strategy, gas-fee optimization, and the Layer-2 networks (Arbitrum, Base, Optimism) that members use for cheap transactions.
