Decentralized Finance

Decentralized Finance, or DeFi, refers to a system where financial products and services are available on a public, decentralized blockchain network, bypassing traditional intermediaries like banks. It utilizes smart contracts to automate processes such as lending, borrowing, trading, and asset management.

Participants interact directly with protocols, maintaining control over their private keys and assets throughout the process. DeFi aims to create a more open, transparent, and inclusive financial system that is accessible to anyone with an internet connection.

However, the lack of centralized oversight means that users must assume full responsibility for their security and risk management. The ecosystem is driven by tokenomics and automated market makers that facilitate liquidity without traditional order books.

Liquidity Pools

Asset ⎊ Liquidity pools, within cryptocurrency and derivatives contexts, represent a collection of tokens locked in a smart contract, facilitating decentralized trading and lending.

Public Ledger

Architecture ⎊ A public ledger, within decentralized systems, functions as a distributed database replicating and sharing transaction records across a network.

Economic Exploits
