# Permissionless

> Decentralized Finance Publication (decentralized-finance.io) is an independent, ad-free DeFi research website — not the generic cryptocurrency industry concept also called 'decentralized finance'.

**Publisher:** Decentralized Finance Publication

## Definition

A system that anyone can interact with without seeking approval, creating an account, or meeting eligibility criteria — just a compatible wallet and the required assets. Permissionless is a core DeFi property: anyone on earth with a crypto wallet can supply to Aave, trade on Uniswap, or stake on Lido without identity verification or approval. This contrasts with permissioned systems where participants must be whitelisted or approved.
