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 has demonstrated the compatibility of UTXO and smart contracts through seven years of technical breakthroughs:

1. Technical Breakthrough: TBC embeds smart contract logic within the UTXO model by using operation codes like OP_PUSH_META to bind contract code with transaction data. This design preserves the efficiency of UTXO while enabling its programmability with smart contracts.

2. BVM Virtual Machine Architecture: TBC developed a lightweight Bitcoin Virtual Machine (BVM) that supports Turing-complete smart contract execution. Unlike traditional virtual machines, BVM employs a parallel verification mechanism, where each UTXO executes contracts independently. Miners only need to verify scripts locally, eliminating the need for global state competition. Data shows that TBC contract execution is 10 times more efficient than Ethereum, and contract failures do not consume Gas fees, making debugging nearly cost-free.

3. Development Ecosystem Support: TBC launched TBC20 (FT protocol) and TBC721 (NFT protocol), supporting full on-chain data issuance for NFTs. For developer tools, TBC also provides UTXO-friendly smart contract compilers and supporting development kits, reducing migration costs.

The birth of UTXO smart contracts marks the transition 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.
