How to Play
Mine ore seeded by the Solana blockhash, earn in-game coins, then redeem them for $HASHROCK.
1 · Enter
Click Play Now on the start page. A wallet is optional to start — you only need Phantom or Backpack (on Devnet) when you want to buy, upgrade, or redeem.
2 · Move & mine
WASD / arrow keys to walk around the village.
Stand next to blue crystal ore and press Space to mine. Moving cancels mining.
Ore spawns from the latest blockhash (≈1 per minute) and persists under a FIFO cap.
If several miners hit the same ore, the reward splits by damage contributed.
3 · Earn & grow
Mining pays in-game coins from the reward pool.
Marketplace — buy axe tiers (Wooden → Diamond) & color skins with $HASHROCK.
Upgrade — level each owned axe 1→10 for more mining throughput.
Repair — restore axe durability.
4 · Redeem
Open your Profile → Request Redeem to burn coins and release $HASHROCK 1:1 to your wallet.
Whitepaper
HASHROCK is built on one rule: the treasury can never owe more than it holds. Earning is redistribution, not emission.
Mint authority is burned — no one can ever print more.
100M (10%) seeds the Reward Pool as the play-to-earn budget.
Solvency invariants
Coins are minted only when a $HASHROCK deposit is confirmed (1:1).
Mining does not mint — rewards come from the Reward Pool, refilled by sinks.
Total coins in circulation ≡ treasury, always 1:1 backed.
Redeeming burns coins, then releases tokens. Evicted ore recycles to the pool.
Sinks & the fixed pie
Upgrades, repairs, and marketplace buys are paid on-chain in $HASHROCK — never in mined coins. Of every sink, 95% recycles to the pool (back to miners) and 5% is the creator cut. Daily ore & payout are fixed: upgrades shift your share of the pie, never grow emission.
Mining payout = a dynamic % of the current pool, so it self-balances — shrinking as the pool drains, growing as sinks refill it. It never hard-zeroes.
Docs
Built like infrastructure: a server-authoritative accounting system with a game on top.
Stack
Client — PixiJS v8 (top-down 2D), Vite + TypeScript.
Server — Colyseus (authoritative) + Postgres with an append-only ledger auditing the 1:1 invariant.
Chain — Solana ($HASHROCK SPL, treasury), on-chain for value only: transfers, sinks, deposit, redeem.
Security
Server validates movement, range & every reward — the client is never trusted for economic values.
Redeem requires a server-verified signature; purchases verify the on-chain payment before granting.
World layout & item stats stay off-chain (gas); only economic value lives on-chain.
