Bitcoin's block space is like a giant unindexed library—after the emergence of the Runes protocol, it has been filled with countless new contents, but the network itself cannot categorize them. Runes allows for the direct creation of fungible tokens on the Bitcoin chain, but the validity of these assets depends on complex transaction sequences and historical traceability. Without an authoritative indexing system to back it up, the market falls into chaos: Does this asset really belong to you? Is this transaction valid? APRO Oracle appears at this moment—it acts like a fair decentralized librarian, solving the problem in its own way.

Unlike projects that rely on centralized indexing services, APRO Oracle takes a more challenging but more blockchain-aligned path. As a decentralized indexer, it utilizes a network of distributed nodes to parse operation codes on the Bitcoin chain, performing transaction sorting and state verification for Runes assets. The benefits of this approach? First, it completely eliminates the possibility of double-spending attacks; second, it feeds these indexed data to other Layer 2 networks or smart contracts through cryptographic proofs, enabling assets to flow across layers.

This decentralized indexing capability is actually the key turning point that connects the Bitcoin ecosystem to the DeFi world. Once developers have the proof-of-ownership data provided by APRO, they can confidently build lending markets or automated market makers for Runes tokens. No more worries about index rollbacks causing asset loss.
