The development of blockchain has reached a new inflection point as the Bitcoin ecosystem advances toward broader utility, higher performance, and improved scalability. In this context, TBC introduces a technological framework designed to extend the capabilities of Bitcoin while maintaining its core principles of decentralization and security. Built as a hard fork of Bitcoin, TBC seeks to deliver improvements in block capacity, smart contract functionality, and cross-chain interoperability, addressing the constraints that have historically limited on-chain innovation within the Bitcoin environment.
TBC inherits critical Bitcoin attributes, including the PoW consensus mechanism, UTXO model, and absolute deflationary economics. This foundation enables compatibility with Bitcoin’s security assumptions while introducing technical enhancements. A significantly enlarged block capacity—expanded from Bitcoin’s traditional 1MB to 4GB—forms the basis of TBC’s performance model. With fees priced by byte rather than coin value, transaction costs remain low even as the network scales. This design aligns fee structure with data usage rather than asset price volatility.
To further reinforce security, TBC employs hierarchically hashed TuringTXID and dynamic data pruning. These mechanisms compress verification pathways, reduce redundant storage, and enhance protection against network-level risks without compromising decentralization.
The 4GB block configuration enables high throughput, positioning TBC for real-world financial activity in dense markets. With transaction fees targeted at approximately $0.0002 and confirmation times reduced to the second-level range, applications requiring rapid settlement—such as payments, trading, and everyday digital interactions—can operate without prohibitive cost structures.
High-frequency activities that are impractical on congested networks become viable when block space and processing capacity expand. The increase beyond 13,000 TPS marks a shift from traditional blockchain constraints to an architecture capable of supporting mass-market demand across Web3 services, gaming, and decentralized finance.
A central advancement introduced by TBC is the deployment of smart contract functionality directly within the UTXO model. Historically, UTXO architecture was perceived as incompatible with complex contract execution due to the absence of global state and the challenges of synchronizing logic.
TBC addresses this through the introduction of the BVM ( Bitcoin Virtual Machine) architecture, a lightweight execution environment embedded within UTXO outputs. By integrating opcodes such as OP_PUSH_META, TBC enables each UTXO to behave as an isolated computational container. This localizes contract operations, removes global competition for state, and preserves the traceability principles of Bitcoin’s original scripting system.
This execution model offers structural advantages. Local state slicing allows each UTXO to encapsulate its contract state, eliminating global conflicts and enabling on-chain verification without reliance on third-party channels. Independent execution across UTXOs enables large-scale parallelism and high contract throughput while retaining deterministic validation. Dynamic pruning and indexed hashing decrease contract storage overhead, allowing contract execution under TB-level blocks while maintaining efficiency.
This architecture supports the TBC20 fungible token protocol and TBC721 NFT protocol. Both leverage parallel verification, reducing congestion and enabling rapid confirmation times. Tokens and NFTs issued via these standards operate natively within the UTXO framework, providing a distinct alternative to the account-based models common on other smart contract platforms.
A significant portion of Bitcoin’s recent on-chain activity involves inscription-based assets. However, their utility is constrained by the performance limitations of the Bitcoin mainnet. TBC introduces an atomic cross-chain mechanism designed to migrate inscription assets to a higher-capacity environment while maintaining strict security guarantees.
The cross-chain process relies on hash-time-locked contracts and elliptic curve cryptography. The mechanism allows an asset to be locked on the Bitcoin chain while a corresponding anchored asset is generated on TBC. The process is defined by strict conditions: the transfer completes fully within a designated block window or the original asset automatically returns to its source. There are no intermediaries, custodial accounts, or multi-signature arrangements. This minimizes systemic risk and prevents unauthorized access.
By combining atomic logic with TBC’s high throughput, inscription assets gain liquidity, lower execution cost, and greater utility across decentralized applications.
TBC’s roadmap emphasizes adoption across the Asia-Pacific region, a market characterized by high digital engagement and rapid economic expansion. With hundreds of millions of daily electronic transactions and a growing population familiar with digital services, the region represents fertile ground for blockchain integration.
TBC outlines three strategic directions for the coming years. Integration into real economies brings fast confirmation and high throughput into retail payments, supply chain platforms, and cross-border remittance systems. Developer ecosystem formation focuses on localized node deployment, developer support programs, and waived on-chain fees for early builders. Compliance-ready infrastructure positions TBC for future collaboration with regulated institutions, enabling potential corridors for national digital currencies and regional stablecoin systems.
By 2028, projections include increased application-level activity, growth in user adoption, and wider integration across urban mobility and payment systems.
Beyond blockchain, TBC is developing AI-aligned tools such as agents, emotional dialogue systems, and decentralized training marketplaces. These initiatives aim to combine distributed ledger technology with emerging intelligent computing services to form hybrid digital infrastructures. Several prototypes, including mobile-based personal blockchain assistants, are already undergoing testing.
TBC proposes a model in which Bitcoin’s foundational strengths—security, decentralization, and the UTXO ledger—are merged with the performance and programmability required for contemporary digital economies. Through expanded block capacity, UTXO smart contract capabilities, and secure cross-chain interoperability, TBC positions itself as a platform intended to activate new layers of utility within the Bitcoin ecosystem.
To support early-stage growth, a 20 million dollar ecosystem fund has been allocated for applications migrating Bitcoin-native assets into high-performance environments. This initiative aims to accelerate the transition toward broader adoption across payments, finance, gaming, and cross-border digital services.
