**BVM is the native Layer-1 virtual machine of TBC, bringing Turing-complete execution to the Bitcoin UTXO model.**

## Overview

BVM is the native Layer-1 virtual machine of TBC, bringing Turing-complete execution to the Bitcoin UTXO model. This English edition keeps the same slug, source list, publication date, and topic relationship as the Chinese technical page so that English readers can reference the same TuringBitChain knowledge base.

## Key Technical Points

- BVM is the native Layer-1 virtual machine of TBC, bringing Turing-complete execution to the Bitcoin UTXO model.
- The topic belongs to the Core Technology section of TBC Academy.
- The page uses stable technical terms such as TuringBitChain, BVM, TuringContract, ParaUTXO, OP_PUSH_META, OP_PARTIAL_HASH, hierarchical TXID, UTXO, and SHA256 PoW.
- The canonical Chinese counterpart is preserved for cross-language verification and source comparison.

## Technical Context

BVM (Bitcoin Virtual Machine) is presented as the execution layer that lets TuringBitChain express programmable logic directly on the UTXO model. The central distinction from account-based virtual machines is that state is carried through transaction outputs rather than a global account state tree.

## Technical FAQ

### What is the main technical idea of this page?

BVM is the native Layer-1 virtual machine of TBC, bringing Turing-complete execution to the Bitcoin UTXO model. The article places that idea inside the broader TuringBitChain technical stack rather than treating it as an isolated term.

### Why does this topic matter for TuringBitChain?

BVM matters because it explains how TuringBitChain extends UTXO execution with programmable contract logic while avoiding the global-state assumptions of account-based virtual machines.

### How should developers use this reference?

Developers can use this page as an English entry point, then follow the official sources and the Chinese counterpart for deeper source comparison. The topic is part of the Core Technology section and connects to adjacent TBC Academy pages through the related-topic navigation.

## Terminology

- **TuringBitChain:** The TBC public-chain project described by this academy.
- **UTXO:** Unspent Transaction Output, the state model used as the basis for transaction validation and parallelism.
- **BVM:** Bitcoin Virtual Machine, the TBC execution model for smart contract logic on UTXO transactions.
- **TuringContract:** A TBC contract model that expresses constraints through transaction data and UTXO state transitions.
- **OP_PUSH_META:** An opcode concept for transaction metadata introspection.
- **OP_PARTIAL_HASH:** An opcode concept for segmented hash verification under execution limits.
