TBC (Turing Bit Chain)

The Chronic Problems of Traditional Cross-Border Remittances
By 2026, the NYSE claims to achieve 24/7 around-the-clock trading, but ordinary people's cross-border remittances remain mired in inefficiency. Mr. Li, a cross-border e-commerce practitioner in Hangzhou, is a typical example: when he paid $50,000 to a U.S. supplier via a certain international bank wire system, the funds only arrived after three days, and the final amount was reduced to $49,780. This discrepancy of $220 was caused by layered intermediary bank fees, telecommunication charges, exchange rate losses, and hidden costs. Mr. Li helplessly stated, "Funds are like being thrown into a black hole, with no transparency throughout the process and no definite return date."
Behind this phenomenon is a rigid global payment system that has persisted for half a century. A McKinsey 2025 report shows that the cross-border payment sector generates $2.5 trillion in annual revenue, with personal remittances contributing $905 billion. The World Bank data indicates that in Q1 2025, average fee rates rose to 6.49%, with some African routes reaching an astonishing 878%. More covertly, the exchange rate spread erodes the wealth of vulnerable groups—the difference between bank quotes and market fair rates often exceeds dozens of times the explicit fees.
Structural Dilemmas of the Old Order
The SWIFT system, born in 1973, was once a symbol of the cross-border communication revolution. Through standardized message formats, SWIFT connected 11,500 financial institutions worldwide into a single information network, processing an average of 46 million transactions daily. However, its essence remains an "information highway," with actual fund transfers relying on a complex network of intermediary banks. When a Chinese bank remits to a Nigerian supplier, it must rely on intermediaries like JPMorgan Chase for settlement, and each additional node incurs costs and time losses. Statrys tracked 2,000 transactions showing that 75% of cross-border payments pass through at least 1.31 intermediaries, with an average duration of 18 hours and 18 minutes; one-third of transactions require cross-day settlement.
The fatal flaw of this system is that network effects entrench vested interests. SWIFT connects 90% of global financial institutions, and any reform must coordinate the interests of over ten thousand entities. Regulatory compliance and anti-money laundering standards are deeply embedded in the system architecture, making reform costs far exceed potential benefits. As the Bank for International Settlements warned in its 2020 report: "The shrinking of the proxy bank network is forcing users to turn to shadow payment systems." This prophecy is being confirmed by reality—cryptocurrencies are eroding the territory of traditional cross-border payments.
Technological Breakthroughs for Disruption
At a time when the old system is struggling, a new generation of payment networks is quietly emerging on the blockchain track. In 2024, the on-chain transaction volume of global stablecoins surpassed $27.6 trillion, exceeding the combined total of Visa and Mastercard. This new payment tool offers three core advantages: 24/7 instant settlement, near-zero transaction costs, and transparent blockchain-based ledgers. More importantly, its technical features perfectly meet cross-border payment needs:
Finality: Blockchain systems using the UTXO model (such as TBC) employ absolute time-lock mechanisms, ensuring transactions are irreversible once confirmed, completely eliminating the "pending" state of traditional banks.
Parallel Processing Architecture: Through sharding technology and layered verification mechanisms, it achieves a processing capacity of 13,000 transactions per second, with a theoretical peak of 100,000 TPS.
Dynamic Fee Model: Based on an intelligent Gas fee market adjustment mechanism, small payments are compressed to $0.0002, and transaction fees adjust with coin price increases to maintain stable fees.
Among these technological breakthroughs, TBC Chain demonstrates a unique competitive advantage. As a comprehensive solution for Bitcoin scalability, TBC inherits the security DNA of the UTXO model and achieves performance leaps through four major innovations:
Three-layer Hash Verification Architecture: Enables lightweight daily transactions and smart contracts, reducing final transaction confirmation time to 200 milliseconds while ensuring security.
First UTXO-based Turing-complete Smart Contracts: An exclusive innovation that breaks through Bitcoin ecosystem constraints, using proprietary OP_Code operation codes to implement the first smart contracts on Bitcoin UTXO, allowing Bitcoin ecosystem to enjoy the unprecedented convenience of smart contracts.
Cross-Chain Atomic Swaps: Relying on TBC20 stablecoin protocol and native HTLC smart contracts, supporting seamless exchange of Bitcoin, stablecoins, and ecosystem tokens, providing a secure and smooth trading experience. Atomic swaps succeed or fail entirely, with no risk of centralized custody loss!
Massive Block Size Infinite Expansion Mechanism: Expands blocks to 4,000 times the size of Bitcoin, achieving a perfect combination of ultra-large blocks and second-level confirmations. It offers near-zero fees while providing real-time payment experiences, and the infinite expansion of large blocks keeps transaction fees consistently low, meeting the needs of frequent payment scenarios.
