Fractal Bitcoin has released its FIP-101 proposal for a standardized data indexing service, aiming to introduce a standardized, open-source, and permissionless data indexing service maintained by core contributors and planned to incorporate it into the Fractal block reward system. Drafted by the UniSat team, a core contributor to Fractal, the proposal is currently under community discussion. According to the proposal, the standardized indexing service will possess technical characteristics such as being completely open-source and permissionless. This service will unify the parsing methods and output structures of different protocols, covering various protocol types including inscription, token, and custom metadata. In terms of incentives, the proposal suggests adjusting the block reward distribution structure, changing the current syndicated mining:free mining (1:2) output ratio to a syndicated mining:free mining:data indexing (1:1:1) three-way split. It also introduces a non-custodial staking mechanism based on Taproot scripts, allowing users to stake FB tokens to a specific indexing service instance and receive corresponding rewards.
