What is a rift?
A rift is an expedition space — a place you breach into from the surface hold. Each rift maps to a catalog entry in the atlas, derived deterministically from on-chain history.
Danger, scale, and density are not hand-tuned level design. They emerge from fee pressure, transaction weight, input complexity, and difficulty at the moment that slice of the chain was sealed.
Why Bitcoin as substrate
Bitcoin is the immutable archive Breachwalker reads. Halving-era rifts carry harsher weight. High-density rifts feel crowded and resource-heavy. Quiet eras read differently on the atlas.
You do not need a wallet to play the alpha. The chain is the world's source code — not a login gate.
- Deterministic — same catalog entry, same rift parameters, every time
- Public data — no proprietary server fiction for core terrain variance
- Lore-aligned — halving moons, strike echoes, sealed vault whispers tie back to chain history
The atlas and the ledger
Walkers share a global atlas: which rifts have been charted worldwide. Your personal ledger shows what you may breach today — open routes, sealed rifts waiting on anchor spikes, rifts you have already run.
Virgin rifts sit on the ledger until a walker extracts for the first time. Then the atlas grows for everyone.
Not a wallet game (alpha)
Closed alpha is off-chain. No seed phrase, no gas, no mint button. You are testing whether breaching rifts and extracting loot feels worth returning to — before item NFTs on Base or marketplace settlement ships.
