BitBus Atomic Swap Concept Guide

A conceptual guide to HTLC, preimages, timelocks, UTXO lineage, and status indexing for atomic swaps.

Overview

A conceptual guide to HTLC, preimages, timelocks, UTXO lineage, and status indexing for atomic swaps. 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

• A conceptual guide to HTLC, preimages, timelocks, UTXO lineage, and status indexing for atomic swaps.
• The topic belongs to the Developer Guides 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

Developer guide pages are written for readers who want to connect the architecture to implementation. They point developers toward official API documentation, wallet documentation, UTXO Compiler documentation, GitHub repositories, and node or contract workflows.

Technical FAQ

What is the main technical idea of this page?

A conceptual guide to HTLC, preimages, timelocks, UTXO lineage, and status indexing for atomic swaps. 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 developer-facing references connect the architecture to official documentation, wallet integration, compiler tooling, node software, and application design.

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 Developer Guides 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.
• MetaSpace: A TBC ecosystem concept based on UTXO NFT-style data ownership and indexing.
• ZeroeDEX: A TBC ecosystem concept for observable order-book and transaction-safety design.
• TuringBridge: A modular cross-chain infrastructure concept around proof verification and integration paths.
• BitBus: A cross-chain atomic-swap concept using HTLC-style logic and UTXO lineage.
