Layer 1
The programmable blockchain behind smart contracts and DeFi.
A proof-of-stake blockchain whose EVM runs smart contracts written in Solidity or Vyper. Home to most DeFi, NFTs and token standards (ERC-20, ERC-721), and the settlement layer for a growing ecosystem of rollups.
EthereumBeginnerA smart contract is code stored on a blockchain that runs automatically and is enforced by the whole network. It holds its own funds and rules, executes deterministically on every node for a gas fee, and powers tokens, DeFi, NFTs and DAOs — bugs and all.

EthereumIntermediateA layer 2 runs on top of a base chain like Ethereum for cheap, fast transactions while inheriting its security. Rollups execute off-chain, then post compressed data back to Ethereum — optimistic ones use fraud proofs, zk ones use validity proofs.

EthereumBeginnerGas fees pay a blockchain to process your transaction, measured as gas used times gas price. Since EIP-1559 the price splits into an automatic base fee that's burned plus a priority tip, and it rises and falls with how full blocks are.

EthereumAdvancedRestaking reuses staked ETH to secure extra services. In EigenLayer, restakers delegate to operators who run software for AVSs and earn more rewards, but each AVS can slash the stake allocated to it, stacking new risks on top.

EthereumIntermediateLiquid staking gives you a token for staked ETH, like stETH or rETH, that keeps earning rewards while usable in DeFi. The main risks are contract bugs, slashing, the token trading below its ETH value, and stake centralization.

EthereumIntermediateUniswap prices tokens from its own reserves: in a constant product pool x * y = k, so the price is the reserve ratio and every trade moves it. Arbitrage keeps pools in line with the market, while LPs bear impermanent loss.

EthereumBeginnerA stablecoin is a token built to track $1. Its peg holds because anyone eligible can mint or redeem near $1, so arbitrage corrects drift. Backing ranges from fiat reserves to over-collateralized crypto to hedged derivatives.
