What is DAI: A Comprehensive Guide to Decentralized Stablecoin in the Ethereum Ecosystem

Dai's Positioning and Significance

In 2017, MakerDAO introduced Dai (DAI), aiming to address financial instability and the need for a decentralized stablecoin.

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 crypto industry, with a market cap of over $4.4 billion and an active user base. This article will analyze its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Dai was created by MakerDAO in 2017 to provide a stable, decentralized cryptocurrency pegged to the US dollar. It emerged during the rise of blockchain technology and DeFi, aiming to offer a stable medium of exchange and store of value resistant to hyperinflation.

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

Important Milestones

• 2017: Dai launched on the Ethereum mainnet, introducing a decentralized stablecoin concept.
• 2019: Multi-Collateral Dai (MCD) upgrade allowed for multiple collateral types beyond ETH.
• 2020: Dai's adoption surged during the "DeFi summer," with its supply growing exponentially.
• 2021: Dai became a key component in major DeFi protocols, with its circulation exceeding 1 billion.

Supported by the MakerDAO community and governance, Dai continues to improve its stability mechanisms and expand its use cases in the DeFi ecosystem.

How Does Dai Work?

No Central Control

Dai operates on the decentralized Ethereum network, free from control by banks or governments. The network of nodes collaborates to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Core

Dai utilizes Ethereum's blockchain as its public, immutable digital ledger, recording every transaction. Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain. Anyone can view the records, establishing trust without intermediaries.

Ensuring Fairness

Dai leverages Ethereum's consensus mechanism (currently Proof of Stake) to validate transactions and prevent fraudulent activities like double-spending. Validators maintain network security by staking ETH and validating transactions, receiving rewards for their efforts.

Secure Transactions

Dai uses public-private key cryptography to secure 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 maintaining pseudonymity. Additionally, Dai employs smart contracts to manage its stability and collateralization process, adding an extra layer of security and automation to the system.

DAI's Market Performance

Circulation Overview

As of September 11, 2025, DAI's circulating supply is 4,442,330,252.789139 tokens, which is equal to its total supply. DAI has an unlimited maximum supply.

New tokens enter the market through the MakerDAO governance 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 the COVID-19 pandemic.

Its lowest price was $0.88196, recorded on March 11, 2023, possibly due to market instability or temporary depegging events.

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