Cryptocurrencies changed the financial world, but stablecoins took things a step further. By offering a stable value tied to fiat currencies, they added a new dimension to the digital asset ecosystem. What started as experimental projects has now grown into a vital part of the financial system, handling hundreds of billions of dollars in less than a decade.
Illustrating this point, the two biggest stablecoins hold market caps of $124 billion and $42 billion each. Let’s explore how they got there.
The first wave (2014)
The stablecoin story began in July 2014 with BitUSD, launched on the BitShares blockchain by future industry leaders Dan Larimer and Charles Hoskinson. As the first crypto-collateralised stablecoin, BitUSD attempted to maintain dollar parity through cryptocurrency backing.
However, its reliance on BitShares as collateral proved problematic, as the volatile nature of its backing asset eventually led to its unpegging from the dollar in 2018.
That same year saw the launch of NuBits, which attempted to improve BitUSD's model by using Bitcoin as collateral. Despite using the more established Bitcoin network, NuBits faced similar challenges. The volatility of its Bitcoin reserves, combined with insufficient capitalisation and lack of diversification, ultimately led to its failure, with the token now trading at a fraction of its intended value.
While these coins are not around today, they built the foundations for the stablecoins that followed.
The rise of fiat-backed solutions
Tether (USDT), launched a few months later in 2014, took a fundamentally different approach that would prove transformative for the industry. Instead of using cryptocurrency as collateral, Tether introduced a simple but effective model: backing each digital token with an equivalent amount of real US dollars held in reserve.
This straightforward approach has led to remarkable success, with Tether's market capitalisation growing to over $124 billion and becoming the dominant stablecoin in crypto markets.
Innovation in collateralisation
In 2017, MakerDAO introduced Dai, bringing sophisticated innovation to the crypto-collateralised model. As a decentralised stablecoin on the Ethereum blockchain, soft-pegged to the US dollar, it represents a key evolution in stablecoin design, moving from fiat-backed models to multi-asset collateralisation.
Dai’s stability is maintained through a hybrid algorithm and a dynamic supply control mechanism called Collateralized Debt Positions (CDPs). This multi-collateral approach, combined with diversified reserves including USD Coin (42%), Wrapped Bitcoin, and fiat-backed assets, ensures Dai’s reliability, making it one of the most stable stablecoins, managing to maintain its dollar peg even during significant market volatility.
Experimenting with algorithms
The most recent chapter in stablecoin evolution came with TerraUSD (UST) and its dramatic collapse in May 2022. Despite backing from substantial Bitcoin reserves (over 70,000 BTC) and sophisticated price stabilisation algorithms, UST demonstrated the limitations of algorithmic stability mechanisms. Its failure reinforced the fundamental principle that stable assets require stable backing.
Key lessons and industry impact
The development of stablecoins has yielded several crucial insights for digital currency innovation:
- The importance of stable collateral for maintaining price stability
- The value of diversification in reserve assets
- The superiority of simple, transparent backing mechanisms over complex algorithmic solutions
- The critical role of sufficient capitalisation in maintaining stability
Today, stablecoins process billions in daily transactions and serve as crucial infrastructure for cryptocurrency markets. And this success has attracted attention from traditional financial institutions and regulators, potentially influencing the development of Central Bank Digital Currencies (CBDCs).
The rapid evolution of stablecoins from experimental projects to essential financial tools demonstrates the potential for innovation in digital finance. As the technology matures, stablecoins are increasingly positioned to play a central role in the future of global financial services, bridging traditional finance with the emerging digital economy.
