What is DAI: Understanding the Decentralized Stablecoin and Its Role in DeFi

Dai's Positioning and Significance

In 2017, MakerDAO introduced Dai (DAI), aiming to address issues such as financial inequality and the need for stable, decentralized currencies in the crypto space.

As the largest decentralized stablecoin on Ethereum, Dai plays a crucial role in the Decentralized Finance (DeFi) ecosystem.

As of 2025, Dai has become a cornerstone asset in the DeFi industry, with 545,939 holders and an active developer community. This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Dai was created by MakerDAO in 2017 to solve the problem of volatility in the cryptocurrency market and provide a stable, decentralized alternative to traditional fiat-pegged stablecoins.

It was born in the context of the growing blockchain technology boom and the need for stable assets in decentralized finance, aiming to provide a stable, decentralized currency that resists hyperinflation and offers economic freedom.

Dai's launch brought new possibilities for DeFi users and protocols seeking stability in the volatile crypto market.

Important Milestones

• 2017: Mainnet launch, achieving a decentralized stablecoin pegged to the US dollar.
• 2019: Major upgrade to Multi-Collateral Dai, introducing support for multiple collateral types beyond ETH.
• 2020: Adoption surges during the "DeFi summer", pushing Dai's market cap to new heights.
• 2021: Ecosystem explosion, with numerous DeFi protocols integrating Dai as a core stablecoin.

With support from the MakerDAO community and governance system, Dai continues to optimize its technology, security, and real-world applications.

How Does Dai Work?

No Central Control

Dai operates on a decentralized network of computers (nodes) spread across the globe, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, giving users greater autonomy and enhancing network resilience.

Blockchain Core

Dai's blockchain is a public, immutable digital ledger that records every transaction. Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain. Anyone can view the records, establishing trust without intermediaries. Dai leverages Ethereum's blockchain, benefiting from its security and smart contract capabilities.

Ensuring Fairness

Dai uses a collateralized debt position (CDP) system to maintain its peg to the US dollar. Users lock up collateral (such as ETH) in smart contracts to generate Dai, ensuring each Dai is backed by excess collateral. The system's stability is maintained through dynamic stability fees and liquidation mechanisms.

Secure Transactions

Dai uses public-private key encryption to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, while transactions remain pseudonymous. Additional security features include smart contract audits and governance-approved risk parameters.

DAI's Market Performance

Circulation Overview

As of November 14, 2025, DAI's circulating supply is 4,539,690,989.71427 tokens, which is equal to its total supply. DAI has an infinite maximum supply, indicating a flexible issuance model.

New DAI tokens enter the market through the MakerDAO system, which affects its supply and demand dynamics.

Price Fluctuations

DAI reached its all-time high of $1.22 on March 13, 2020, likely driven by market volatility and increased demand for stablecoins during a period of economic uncertainty.

Its lowest price was $0.88196, occurring on March 11, 2023, possibly due to market-wide instability or temporary deviations from its peg.

These fluctuations reflect market sentiment, adoption trends, and external factors affecting the stablecoin ecosystem.
