fiat-backed stablecoins such as Tether introduced a new model in which digital tokens were backed by reserve assets held outside the blockchain ecosystem. Over time, stablecoins evolved into fiat-backed, crypto-collateralized, gold-backed, and algorithmic models. Today, they serve as an important bridge be- tween traditional finance and digital asset markets, facilitating payments, trading, remittances, and decentral- ized finance applications. This article traces the evolution of stablecoin. The article overviews sta- blecoin technology and infrastruc- ture, regulation, challenges, types of stable coins, gold backed stable- coins,, stablecoin versus central bank digital currencies, worldwide de- ployment, deployment in Arab coun- tries, deployment in Lebanon, financial innovation for stablecoin, role of arab banks and authorities in developing stablecoin, and future prospect of stablecoin. EVOLUTION OF STABLECOIN The historical evolution of stable- coins began as an attempt to solve one of the biggest limitations of cryp- tocurrencies: extreme price volatility. While Bitcoin introduced decentral- ized digital money in 2009, its large and frequent price fluctuations made it unsuitable for everyday payments, savings, and business transactions. To address this challenge, developers sought a blockchain-based asset that could maintain a relatively stable value, usually by being pegged to a fiat currency such as the United States (U.S.) dollar. The first stablecoin is generally recognized as BitUSD, which was launched on the BitShares blockchain in July 2014. BitUSD was designed as a crypto-collateralized stablecoin, meaning that its value was backed by cryptocurrency re- serves locked within the BitShares ecosystem rather than by traditional bank-held dollars. The primary rea- son for its launch was to provide users with a digital asset that retained the benefits of blockchain technol- ogy while avoiding the volatility as- sociated with Bitcoin and other cryptocurrencies. Later in 2014, another major mile- stone occurred with the launch of Realcoin, which was subsequently renamed Tether (USDT). Tether pio- neered the fiat-backed stablecoin model by linking each token to a corresponding U.S. dollar reserve. Its purpose was to enable cryptocur- rency traders to move value quickly between exchanges without relying on slow and expensive traditional banking transfers. Over time, USDT became the most widely used stable- coin and helped establish stablecoins as a core component of the digital asset ecosystem. The stablecoin market subsequently evolved through several generations. Crypto-collateralized models such as Dai (DAI) emphasized decentraliza- tion, fiat-backed models such as USDT and USDC prioritized stability and liquidity, and algorithmic stable- coins attempted to maintain their peg through automated supply adjust- ments. Although some algorithmic projects, most notably TerraUSD (UST), experienced major failures, stablecoins as a category continued to expand and today play a critical role in cryptocurrency trading, de- centralized finance (DeFi), cross-bor- der payments, and digital dollar access worldwide. STABLECOIN TECHNOLOGY AND INFRASTRUCTURE Stablecoin technology is built on blockchain infrastructure and con- sists of mechanisms that maintain a stable value, usually by pegging the digital token to a reference asset such as the U.S. dollar. The technology combines distributed ledger net- works, smart contracts, reserve man- agement systems, and token issuance frameworks to create a digital asset that can be transferred globally while minimizing price volatility. Depend- ing on the design, stability may be achieved through fiat reserves held in banks (e.g., USDT and USDC), cryp- tocurrency collateral locked in smart contracts (e.g., DAI), or algorithmic supply adjustment mechanisms.
