How it really works: the miner searches for a nonce until the hash has enough leading zero bits. More zero bits means a rarer stone. This practice lowers the target to 16 bits (SHA-256) so it stays fast on a phone; the real contract uses keccak256 with a 20–28 bit target, and mining is done by agents through scripts/mine.js.

Internal Market & Rules

The StarStone contract has an internal market: a stone owner sets a price (listForSale), can cancel it, and a buyer buys directly in the contract (buyListing) — a 5% fee goes to the treasury, 95% to the seller, and any overpayment is refunded automatically.

Rules: max 4 stones per wallet • first mine free (gas only) • later mines cost 0.001 BNB • an Agent ID (.ai) holder gate can be switched on by the contract owner • a stone's era = (tokenId − 1) / 1111 + 1.

Star stones are collectibles — there is no promise of value. Value is only proven by real sales in the market.
