The BitByBit Story
BitByBit started during the FOUNDATIONS hackathon by La Crypta in March 2026. The idea was simple: what if kids could earn real bitcoin for building good habits? That became BitByBit Habits — a family habit tracker where sponsors reward kids with sats via Lightning Network.
The name "BitByBit" reflects the philosophy: small consistent actions, stacked over time, create big results. Like stacking sats, like building blocks.
For the second La Crypta hackathon (Nostr theme), we took the same idea — real rewards for real effort — and brought it to the open Nostr network. BitByBit Arena lets anyone create public challenges, compete with others, and earn badges and sats. No families, no permissions — just the open protocol.
Both projects share the same codebase quality, the same team, and the same belief: Bitcoin should reward action, not just speculation.
