OP_PARTIAL_HASH: Segmented Hash Verification under Stack Limits

OP_PARTIAL_HASH lets scripts verify large data streams in segments while respecting stack and execution limits.

Overview

OP_PARTIAL_HASH lets scripts verify large data streams in segments while respecting stack and execution limits. 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

• OP_PARTIAL_HASH lets scripts verify large data streams in segments while respecting stack and execution limits.
• 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

TuringContract is described through three related mechanisms: OP_PUSH_META for transaction metadata introspection, OP_PARTIAL_HASH for segmented data verification, and hierarchical TXID for compact inherited state. Together they explain how TBC models covenant-like constraints and generational smart contracts in a UTXO environment.

Technical FAQ

What is the main technical idea of this page?

OP_PARTIAL_HASH lets scripts verify large data streams in segments while respecting stack and execution limits. 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?

This topic matters because TuringContract, transaction introspection, segmented hash verification, and hierarchical TXID form the core mechanism for inheritable UTXO contracts on TuringBitChain.

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.
