Second-settlement for cross-border payments. These figures paint a picture of a thriving new world of on-chain finance. Yet, a counterintuitive reality underpins this boom: the massive market is still powered by a layer of "borrowed" infrastructure. As stablecoin valuations surpass the GDP of many nations, the very public chains they rely on may become their greatest bottleneck to future growth. I. Structural Fragility Behind the Boom: The "Parasitic" Dilemma of Stablecoins The narrative around stablecoins has shifted from "crypto trading pair" to "global financial infrastructure." Cross-border payments, a market with annual transaction volumes exceeding $150 trillion, is seeing a crack opened by on-chain stablecoins. The traditional SWIFT network takes an average of 3-5 days to settle a cross-border transfer, with total fees reaching up to 6.5% of the transaction value. In contrast, blockchain-based stablecoin transfers finalize in seconds, typically costing less than $0.01. This order-of-magnitude improvement is directly fueling a surge in crypto payment adoption across Southeast Asia, Africa, and other emerging markets. However, this prosperity is built on a fragile foundation: the vast majority of stablecoins are "parasites" on public chains not designed for their core use case. USDT and USDC are primarily issued on account-model chains like Ethereum and Tron. These chains were fundamentally designed to support complex, state-sharing smart contracts, not high-throughput, low-latency, simple value transfer. This creates a fundamental contradiction: the core use case for a stablecoin—payment—demands extremely high throughput, minimal latency, and near-zero cost. The underlying layer it depends on, however, is forced to make significant performance compromises to accommodate global state synchronization and the complexity of smart contract execution. The result is a perverse cycle. Every time stablecoin adoption spikes due to a catalyst (like a surge in remittances from an emerging market), the Gas fees on its underlying chain spike in tandem. During the DeFi summer of 2021, the cost to simply transfer USDT on Ethereum exceeded $50. This directly contradicts the goal of financial inclusion: the users who need low-cost remittance services the most are priced out by exorbitant on-chain costs. A deeper隐患 lies in security and settlement finality. In the account model, complex smart contract interactions enable infinite possibilities but also introduce immense risk. Reentrancy attacks, contract vulnerabilities, oracle manipulation… these risks are fundamentally misaligned with a stablecoin's role as a "store of value" and medium of exchange. An asset intended to act as "digital cash" operates in an environment rife with the unpredictable risks of smart contracts—a systemic mismatch. Existing solutions, whether migrating to other high-performance L1s or relying on various L2 scaling solutions, are merely patches within the "parasitic" framework. They address some performance issues but cannot resolve the fundamental model-level contradiction: the global state of the account model is an inherent bottleneck for serialized processing. II. The Root of the Problem: We Chose the Wrong "Container" for Value Transfer Is there a path that fundamentally aligns with the stablecoin's core need for "efficient, secure, cheap value transfer"? The answer may have been in front of us all along, overlooked by most projects: return to Bitcoin's UTXO model and make it programmable. This is not a novel hypothesis but a validated design philosophy. The Bitcoin network itself is the most secure, decentralized value settlement layer in human history. Its UTXO model offers two native advantages for payment scenarios: privacy (transactions are difficult to link and trace) and parallel potential (independent UTXOs can be processed in parallel). However, the non-Turing completeness of Bitcoin's scripting language prevents it from supporting the necessary logic for stablecoin issuance, redemption, and compliance checks. Thus, the industry forked onto two paths. One path, exemplified by Ethereum, fully embraced the account model, trading performance and model purity for smart contract flexibility. The other path involves working around the edges of UTXO, adding functionality through sidechains, drivechains, or complex multi-layer structures (like the RGB protocol), often sacrificing security assumptions or user experience. The root cause is that the industry accepted the notion that "UTXO models cannot implement complex logic at Layer-1" as an insurmountable technical obstacle. Consequently, all solutions avoid deep modification of the UTXO model itself, either starting from scratch or applying complex "patches." This has led to an awkward situation: the model most suited for value settlement (UTXO) is abandoned for lacking programmability, while the widely adopted programmable model (account model) has an inherent conflict with efficient value settlement in its underlying logic. The real breakthrough lies precisely in overcoming this "default obstacle." If one can grant UTXO Turing-complete smart contract capability at Layer-1 without destroying its core advantages (parallelism, privacy, simplicity), then a底层结算层 tailored for stablecoins and global payments truly becomes possible. This is not theoretical. A project has already run verifiable results on this "road less traveled." III. UTXO-Native Smart Contracts: The Overlooked Optimal Solution and TBC's Implementation While the market debates between L2 Rollups and heterogeneous chains, TuringBitChain (TBC) has chosen a more fundamental technical path: modifying the UTXO model itself to support Turing-complete smart contracts at Layer-1. This is not just "another Bitcoin L2" but a底层重构 starting from how transactions are generated. TBC's core innovation is its TuringContract. Through its独创的 OP_PUSH_CODE technique, it embeds smart contract code and data into the chain of UTXO consumption and creation, achieving "local Turing completeness." Each contract's execution is isolated within a specific set of UTXOs, fundamentally different from the account model where all contracts share a global state. The direct benefit is: transactions from different contracts can be processed in parallel, without blocking each other. What does this mean for the stablecoin scenario? Imagine a cross-border payment platform simultaneously processing millions of small USDT remittances from Southeast Asia, Africa, and Latin America. On Ethereum, these transactions enter the same mempool, competing for block space, causing network congestion and fee spikes. In TBC's UTXO model, as long as these transactions consume different UTXOs (a common occurrence), they can be validated and packaged in parallel by different nodes in the network. This is the theoretical basis for infinite scalability. Performance data illustrates the difference直观地. The TBC testnet has achieved over 13,000 TPS. This was not attained by sacrificing decentralization (it uses the same SHA-256 PoW consensus as Bitcoin) but is the natural result of unlocking UTXO's parallel potential. In comparison, Ethereum mainnet TPS has long hovered between 15-30. Even on Optimistic Rollups, the theoretical TPS ceiling is typically around 2,000-4,000, with the added caveat of withdrawal delays. A反驳 might be: "Other UTXO chains, like Cardano, also support smart contracts, but their performance hasn't improved by an order of magnitude." The key difference lies in the implementation layer. Cardano's EUTXO model is indeed an innovation, but its contract execution is still largely constrained by global state coordination. TBC's TuringContract is a pure Layer-1 implementation; contract logic takes effect directly within the spending rules of UTXOs, requiring no additional consensus or state layer. The path is shorter, and efficiency is higher. More critical is the fee model. Traditional blockchains suffer from the paradox of "more users, higher fees," severely limiting stablecoins' development as tools for financial inclusion. Through its layered hashing and pipeline processing design, TBC allows block capacity to dynamically expand to the terabyte level. A design goal of its economic model is for transaction fees to approach zero as user scale grows. This is a颠覆性的 advantage for micropayment scenarios involving millions of transactions. Challenges exist, of course. The developer ecosystem for the UTXO model needs to be built from the ground up, and the programming paradigm for smart contracts differs from EVM, constituting short-term adoption barriers. However, the existence of TuringBridge, a cross-chain module, provides a channel for ecosystem integration. In the long run, a dedicated settlement layer optimized for value transfer to the extreme, with its simplicity and high performance, holds irresistible appeal for stablecoin issuers and payment service providers. IV. From "Parasitic" to "Symbiotic": A Future Designed for Value Flow Looking ahead, the stablecoin market will not stop at $230 billion. As central banks explore CBDCs and traditional financial assets continue migrating on-chain, the scale of on-chain value flow will grow exponentially. At that point, the bottlenecks of the underlying infrastructure will be彻底暴露. The future格局 may not be "one chain to rule them all" but will likely see professional specialization. Some chains will focus on highly complex DeFi derivatives trading (requiring strong state sharing), while others will specialize in high-throughput asset settlement and payments. A high-performance settlement layer based on UTXO-native smart contracts could well become the ultimate form in the latter category. In this vision, TBC and the BVM ecosystem it represents have a clear定位: not to be a "world computer" but a "world settlement layer." It does not seek to host all types of smart contracts but focuses on perfecting value transfer (including stablecoins, tokenized assets, CBDCs)—as secure as Bitcoin, as fast as Lightning, and as cheap as a text message. When massive volumes of transactions—cross-border payments, payroll, supply chain finance—no longer need to pay a high premium for underlying network congestion and uncertainty, true financial inclusion will have taken a critical step forward. Stablecoins will cease to be merely speculative trading pairs or tools to escape currency devaluation. They will become the "new bloodstream" reshaping the efficiency of global capital flow. A $230 billion market calls for an underlying layer that is no longer "running naked." Should we continue building skyscrapers on "borrowed" foundations, or return to the essence of value transfer and build a cornerstone that matches its needs from the ground up? This choice will determine the slope and ceiling of the next phase of crypto-financial growth. TBC's two years of先行实践 offer a technical answer. The market is voting with real capital for "payment-first" infrastructure. As the stablecoin market marches toward a trillion dollars, whoever masters the efficiency of the settlement layer will grasp the pulse of finance in the new era. ## 资料入口 - 站内 HTML：https://www.turingbitchain.io/tbc-academy/articles/tbc-stablecoin-settlement-backbone-en/ - Markdown 镜像：https://www.turingbitchain.io/tbc-academy/articles/markdown/tbc-stablecoin-settlement-backbone-en.md - TBC 学院首页：https://www.turingbitchain.io/tbc-academy/ --- 发布日期：2026-06-09 数据更新日期：2026-06-09 ## Sources 1.
