In-Depth Analysis of TuringBitChain: How UTXO Gains Smart Contract Capabilities

Limitations of the UTXO model

Although the UTXO model performs excellently in concurrency and security, its original design does not support state variables and complex logic, which prevents Bitcoin from natively supporting smart contracts, limiting its application expansion in the Web3 world.

TuringBitChain’s technical solutions

TuringBitChain proposed two major technological innovations:

• TuringTXID: By applying hierarchical pruning and hash structures to transaction data, it supports partial data verification and data reuse, enhancing data processing and verification efficiency.
• Turing Contract (TuringContract): A smart contracts system implemented based on UTXO, which generates new UTXO instances with each execution of the contract, realizing a high-concurrency contract execution logic with “no global state.”

This design allows TBC to have complete contract processing capabilities without sacrificing the advantages of the UTXO model.

How do smart contracts run on TBC?

The TuringContract execution process has the following characteristics:

• Contracts can be executed without confirmation (Zero Confirmation), with very low latency;
• There is no MEV risk or reentrancy attack;
• The contract results are written into the transaction output and verified for correctness by nodes, without the need for full nodes to execute the logic.
• Multiple contract instances can run in parallel, fully utilizing multi-core CPUs and improving TPS.

This makes TBC one of the very few UTXO public chains that currently supports high-performance, low-cost, and strong security Layer 1 smart contracts.

The mining mechanism and token economy of TBC

TBC adopts the same SHA-256 mining mechanism as BTC, with an initial issuance of 210 million tokens, the vast majority of which are distributed through lock-up, and the remaining 142 million are available for mining. The economic model also includes a community governance DAO voting mechanism to ensure that the early lock-up release is controllable.

Transaction fees are extremely low (

Application prospects and development potential

The design goal of TuringBitChain is to become a high-performance infrastructure for global Web3 applications, with the advantages of “Bitcoin-level security + flexibility of smart contracts,” making it extremely suitable for deploying large-scale applications such as decentralized finance, NFTs, gaming, and notarization.

In the future, TBC is expected to become a “functional sidechain” under the BTC system, similar to ARB and OP in Ethereum, and is a key piece to activate the Bitcoin ecosystem.
