Ecosystem of blockchain-based applications using wallets, tokens, and decentralized protocols.

Definition

Web3 refers to an ecosystem where users interact with decentralized protocols via wallets and cryptographic signatures, often involving tokens and smart contracts.

In plain English Ecosystem of blockchain-based applications using wallets, tokens, and decentralized protocols.

Why this matters

Why it matters: Privacy tradeoffs differ: on-chain activity is often public, so privacy may require additional techniques (mixing, ZK proofs, minimization).

Example

Example: dApp uses wallet signatures for authentication and smart contracts for execution.
