FIP-101 Proof Rules Update

Medium6.0

◆ Description

Fractal Bitcoin plans to activate FIP-101 at block 1,925,280 (~06:30 UTC), extending the proof submission window to 720 blocks and introducing a progressive staking reward decay that reaches zero at 1,440 blocks.

◆ Why it matters

FIP-101 extends Fractal Bitcoin's proof submission window to 720 blocks and hard-caps staking reward decay at 1,440 blocks, adjusting validator economics on a known block height. The change is a specific, scheduled protocol parameter update rather than a new mechanism, so its re-rate impact is contained. Active validators and miners get clearer, more predictable reward curves, while broader market positioning remains unchanged.
