# Index Mining Fractal Standard Indexing Service is a standardized, open-source, and permissionless data indexing system and integrated into Fractal's block reward mechanism to ensure long-term, incentivized data availability across the ecosystem. * Indexing software will be open-source. Participation is permissionless. Anyone may operate indexing services permissionlessly. Miners and mining pools may also participate by running index nodes or joining the staking mechanism. * Standardized data output provides developers with consistent, reliable data structures across all supported protocols. * Non-custodial Staking: Users stake FB through Taproot scripts. Funds always remain under user private-key control. Users may exit and migrate between indexing instances without operator permission. * Non-blocking Settlement: Index verification and reward settlement must not enter the block production critical path. Index rewards may be processed asynchronously or with delay to preserve chain liveness. ⚠️ We are currently developing and open-source a lightweight indexer to ensure data availability and open for anyone who might want to test the indexing and staking mechanism. Please stay tuned. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
