Fractal Bitcoin has unveiled FIP-101, a proposal to establish a standardized data indexing service within its block reward system. Developed by the UniSat team, this initiative seeks to create an open-source, permissionless indexing service managed by core contributors. The service aims to standardize parsing methods and output structures for various protocols, including inscriptions and tokens. The proposal suggests modifying the block reward distribution to a 1:1:1 ratio among collaborative mining, free mining, and data indexing. Additionally, it introduces a non-custodial staking mechanism using Taproot scripts, enabling users to stake FB tokens to indexing service instances for rewards.
