streak/v0 package

Overview

Package streak is an on-chain check-in streak tracker: call CheckIn once per "day" to keep a streak alive, miss one and it resets to 1.

There is no wall clock on-chain, so a "day" here is a fixed window of BlocksPerDay blocks: day = ChainHeight() / BlocksPerDay. That makes every streak decision a pure function of block height — deterministic, replayable, and impossible to game by waiting for a favourable timestamp.

State is per-caller and append-only in spirit: an address's best streak is never lowered, so breaking a run costs the current streak but not the record.

This is a stateful app with nothing reusable to extract, so it ships as a lone realm rather than a p/ library + demo pair.

Function

CheckIn

func CheckIn(cur realm) int
Ask AI Claude ChatGPT

CheckIn records a check-in for the caller and returns the resulting streak.

Checking in twice in the same window is rejected — the streak only moves when the window does. A gap of exactly one window continues the streak; any larger gap restarts it at 1.
