An Ethereum block bundles validated transactions, state changes, fees and smart contract calls. Validators finalize blocks, chaining them to securely order and record network activity on the blockchain.
NFTs (non-fungible tokens) are blockchain-based digital tokens that certify ownership and uniqueness of digital assets-art, music, virtual real estate-enabling secure transfer, provenance, and scarcity.
Liquid staking lets ETH holders earn staking rewards while keeping liquidity. stETH tokens (e.g. from Lido) represent staked ETH, are tradable and yield-bearing, enabling DeFi access without unbonding.
DeFi on Ethereum delivers permissionless financial services via smart contracts-lending, decentralized exchanges, stablecoins-enabling transparent, programmable, and interoperable finance without central intermediaries.
ERC-1155 is a versatile multi-token Ethereum standard enabling efficient management of fungible, non-fungible, and semi-fungible assets in a single contract, improving gas efficiency and batch transfers.
Most NFTs use the ERC-721 standard, which defines unique non-fungible tokens on Ethereum. ERC-721 enables distinct ownership, provenance and transferability for one-of-a-kind digital assets.
Learn how Ethereum staking works: lock ETH to help secure the network and earn rewards. Explore validator roles, risks, lock-up periods, and practical steps to stake safely for steady passive income.
Soulbound tokens (SBTs) are non-transferable NFTs that bind credentials and identity to a wallet, enabling verifiable reputation, credentials, and governance while preventing market transferability.
zk-Rollup combines off-chain transaction batching with zero-knowledge proofs to validate state changes on-chain, boosting scalability and security while minimizing gas costs and latency.
Explore popular Ethereum testnets-Goerli, Sepolia, and Holesky-used for safe dApp development, testing, and network experimentation before mainnet deployment.
