DeFi
Juga dikenal sebagai: Decentralized Finance, Open Finance
A financial ecosystem built on blockchain technology that provides traditional financial services like lending, trading, and insurance without banks or intermediaries.
DeFi (Decentralized Finance) is an umbrella term for financial applications built on blockchains that replicate and expand upon traditional banking services. Instead of relying on banks, brokers, or insurance companies, DeFi uses smart contracts to provide financial services that are open, permissionless, and globally accessible.
DeFi Categories:
| Category | What It Replaces | Top Protocols |
|---|---|---|
| Lending/Borrowing | Banks | Aave, Compound, Morpho |
| Trading (DEXs) | Stock exchanges | Uniswap, Curve, Jupiter |
| Derivatives | Options/futures brokers | GMX, dYdX, Synthetix |
| Insurance | Insurance companies | Nexus Mutual, InsurAce |
| Yield | Savings accounts | Yearn, Pendle |
| Stablecoins | Fiat currency | MakerDAO (DAI), FRAX |
DeFi Principles: - Permissionless: Anyone with a wallet can participate - Non-Custodial: Users retain control of their funds - Composable: Protocols can be combined like building blocks ("money Legos") - Transparent: All transactions and code are publicly auditable - 24/7: No market hours, no holidays, no downtime
DeFi Growth:
| Metric | 2020 | 2021 Peak | 2023 Low | 2026 |
|---|---|---|---|---|
| Total TVL | $1B | $180B | $40B | $100B+ |
| DEX Volume (monthly) | $1B | $170B | $30B | $150B+ |
| Active Users (monthly) | 50K | 4M | 2M | 10M+ |
Key Risks: - Smart Contract Bugs: Over $5B lost to DeFi exploits since 2020 - Oracle Manipulation: Incorrect price feeds causing bad liquidations - Impermanent Loss: Liquidity providers losing to price divergence - Regulatory Uncertainty: Governments still defining DeFi rules - Complexity: Steep learning curve for new users
DeFi vs. CeFi (Centralized Finance): CeFi platforms (Coinbase, Binance) offer similar services but hold user funds and require identity verification. CeFi is simpler but introduces counterparty risk, as FTX's collapse demonstrated. DeFi eliminates counterparty risk but adds smart contract risk and self-custody responsibility.
