How has DeFi evolved from its inception to the present day
The traditional banking system requires the participation of clearing houses, brokers, and depositories to conduct any financial transaction. These intermediaries accumulate commission costs and create single points of failure in the form of centralized servers.
Decentralized finance (DeFi) has replaced the bureaucratic apparatus with self-executing smart contracts on the blockchain. The architecture of the software code allowed users to credit, exchange and stake digital assets without going through KYC procedures.
Moving from simple smart contracts to liquidity pools
The first decentralized exchanges (DEX) copied the order book from classical trading, which led to price slippage with low buyer activity. Matching applications required high gas costs to execute each transaction within the Ethereum network.
The situation has changed with the introduction of the Automatic Market Maker (AMM) algorithm, which eliminated the need for a counter counterparty to exchange tokens. Users have started locking their paired assets in a single smart contract, forming a continuous pool of liquidity.
The mechanics of AMM is based on the mathematical constant product formula:
- the algorithm calculates the asset's exchange rate based on the ratio of two tokens in a smart contract;
- when buying back one coin, its scarcity automatically raises the price for the next trader;
- Liquidity providers receive a percentage of trading commissions in proportion to their share in the pool.
This model made it possible to instantly exchange ERC-20 tokens, even with minimal trading volumes. Arbitrageurs have taken over the balancing function of exchange rates, equalizing prices between decentralized and centralized platforms.
Integration of oracles and cross-chain bridges
The blockchain is an isolated environment that does not have built-in mechanisms for obtaining data on quotes of fiat currencies or stocks. The launch of algorithmic stablecoins and lending markets required reliable information from the external Internet.
The problem has been solved by decentralized oracles such as Chainlink, which aggregate data from dozens of cryptocurrency exchanges. A network of independent nodes validates price feeds and translates them into smart contracts, eliminating the risk of exchange rate manipulation through a single hacked source.
In parallel, the infrastructure of interaction between different blockchains was developing:
- cross-chain bridges block the native asset in the source network using a smart contract;
- the protocol issues a synthetic copy of the blocked coin on the target network;
- during the reverse transfer, the synthetic token is burned, freeing up the original liquidity.
The fragmentation of capital between the Ethereum, Solana and Polygon networks has decreased due to the liquidity routers. Users were able to transfer stablecoins between blockchains in a single transaction without losing conversion fees.
Regulatory pressure and institutionalization of protocols
The scaling of the decentralized finance sector attracted the attention of regulatory authorities, who classified profitability farming as trading in unregistered securities. The anonymity of the liquidity pools has become an obstacle to the entry of institutional capital due to the strict AML requirements.
In response, the developers began to implement hybrid protocols with isolated pools, access to which is opened only after identity verification. Investment funds have received a legal tool for making money on staking without violating corporate compliance.
The vector of DeFi development has shifted towards tokenization of real assets (RWA), allowing the digitization of treasury bills and real estate. The integration of fiat instruments into the blockchain ensures stable profitability for the protocols, independent of the volatility of the cryptocurrency market.
