Fractal Bitcoin: FIP-101 updates mining and proof rules

Fractal Bitcoin’s announcement says FIP-101 is expected to activate in early August, bringing full Index Mining block rewards of 25 FB per block and updated indexer proof submission rules.

The reward schedule ties payment to timely proof submission. Rewards move through decay stages of 5%, 8%, 12%, 16%, 24%, and 25%, reaching zero at 1,440 blocks, while the 720-block window defines the initial submission period. This changes how mining rewards are distributed and gives indexers a specific deadline for maintaining eligibility.

FIP-101 also adds an FB staking pathway, creating another network-participation use for the token alongside mining. The change makes these incentives available, but its effect on FB demand and participation will depend on actual staking, mining, and proof-submission behavior.

The past six months have been an important period for Fractal Bitcoin.
