TBC (Turing Bit Chain)

Large Block Technology: The Core Logic to Break Through Performance Bottlenecks
The Bitcoin mainnet's 1MB block capacity is like the capillaries of a digital pipeline, making it difficult to support large-scale transaction demands. As blockchain application scenarios expand, this design has become a core constraint on ecosystem development. TBC addresses this issue through two core technologies:
1. Block Expansion Mechanism: TBC increases the initial block capacity to 4GB by utilizing layered hashing technology and dynamic data pruning techniques, allowing a single block to contain data equivalent to 900 HD videos while maintaining verification efficiency comparable to a 1MB block.
2. Infinite Expansion Solution: To cope with future explosive data growth, TBC has designed and patented a parallel high-performance computing node technology that theoretically supports unlimited expansion, easily meeting the PB-level data storage needs of the Metaverse era.
Compared to Ethereum's sharding solution and Solana's vertical scaling, TBC's large block approach is closer to traditional internet scaling logic. For example, Alipay processes millions of transactions per second during peak hours, and TBC, with 4GB blocks and parallel verification technology, can theoretically reach over 13,000 TPS, with transaction confirmation times shortened to 200ms. This performance advantage makes it the preferred public chain for high-frequency payments, supply chain finance, and other scenarios.
II. UTXO Smart Contracts: Paradigm Shift in the Bitcoin Ecosystem
The UTXO model was once considered a forbidden zone for smart contracts. Ethereum founder Vitalik Buterin once asserted that "UTXO and smart contracts are incompatible," but the TBC team proved the compatibility of UTXO and smart contracts through seven years of technical breakthroughs:
1. Technical Breakthroughs: TBC embeds smart contract logic within the UTXO model, binding contract code and transaction data through operation codes like OP_PUSH_META. This design preserves UTXO's efficiency while granting it programmable smart contract capabilities.
2. BVM Virtual Machine Architecture: TBC developed a lightweight Bitcoin Virtual Machine (BVM) supporting Turing-complete smart contract execution. Unlike traditional virtual machines, BVM uses a parallel verification mechanism, with each UTXO executing contracts independently. Miners only need to verify scripts locally, without global state competition. Data shows that TBC contract execution efficiency is ten times higher than Ethereum's, and contract failures do not deduct Gas fees, reducing debugging costs to nearly zero.
3. Development Ecosystem Support: TBC launched TBC20 (FT protocol) and TBC721 (NFT protocol), supporting full on-chain NFT issuance. For developer tools, TBC also provides UTXO-friendly smart contract compilers and supporting development kits, lowering migration costs.
The birth of UTXO smart contracts marks the transformation of the Bitcoin ecosystem from "digital gold" to an "all-in-one public chain." TBC's developer ecosystem has attracted teams across DeFi, GameFi, and other fields, demonstrating strong commercial potential.
