memba_arcade_leaderboard_v1 package

Overview

Package memba_arcade_leaderboard_v1 is the funds-free, verified-score ledger for the Memba arcade (BARRICADE, Space Invaders, and future games — one realm, boards keyed per game slug). Nothing here trusts a client number: an authorized ATTESTER (the backend verifier's key) re-simulates a submitted input log and attests only the reproduced result. The chain stores the attested result plus a commitment to the log (its sha256) — the log itself stays off-chain; "verified, never trustless" is the public contract.

SAFETY: there is NO banker, NO transfer, and NO OriginSend anywhere — the fund-drain risk class does not apply. The only trust boundary is who may attest (owner ∪ the attester allowlist); every write emits an event. Two buckets never mix: the competitive DAILY BOARD (one best entry per address per game per day, shared seed) and personal TRAINING RECEIPTS (practice runs — a verified flex, never ranked).

The game slug is shape-validated only — there is deliberately NO on-chain game registry: the realm is funds-free, so the worst a typo'd slug can do is fragment a board, and the attester (not the player) authors the slug.

Functions

AcceptOwnership


              func AcceptOwnership(cur realm)

Ask AI

AcceptOwnership completes the handoff. Only the staged pendingOwner may call it.

AddAttester


              func AddAttester(cur realm, addr address)

Ask AI

AddAttester allowlists an ADDRESS (the backend verifier's dedicated low-privilege key — never the deploy multisig itself) as an authorized result source. Owner only.

AttestReceipt


              func AttestReceipt(cur realm, game string, addr address, day, seed string, score, simVersion int64, stateHash, logHash, stats string)

Ask AI

AttestReceipt mints a personal training receipt — a verified "I did this run", never ranked. Attester-only; capped per address per (game, day) and ring-capped per address. Fulfills (and clears) a matching player-paid RequestReceipt if one is staged.

AttestScore


              func AttestScore(cur realm, game string, addr address, day, seed string, score, simVersion int64, stateHash, logHash, stats string)

Ask AI

AttestScore writes (or improves) an address's entry on a game's competitive board for a day. Attester-only. The verifier batches a day's results into one multi-msg tx at day close, plus spam-capped singles for the "certify now" flow. Re-attesting the same game/address/day only ever RAISES the score (Second Wind). A log hash already attested for that game-day for a DIFFERENT address is rejected — on a shared daily seed a valid input log is portable, so first-submitter wins (replay-theft defense). `stats` is the attester-authored per-game JSON blob (waves, wins, levels, …) — never ranked, only echoed by reads.

GetBoardJSON


              func GetBoardJSON(game, day string, offset, limit int) string

Ask AI

GetBoardJSON returns a page of a game-day's board, rank-ordered, as {"game":…,"day":…,"total":N,"entries":[…]}. Reads sort the day's entries on demand — fine for a testnet-scale board; a rank index (points_v1-style) is the v2 upgrade if daily boards grow past a few thousand entries.

Command

gnokey query vm/qeval -remote "https://rpc.onyx.testnets.gno.land" -data "gno.land/r/g1a9g8nu3m0xgx58hh36fph49e2xkqm9axlxuf5z/memba_arcade_leaderboard_v1.GetBoardJSON(,,,)"

GetEntryJSON


              func GetEntryJSON(game, day, addr string) string

GetReceiptsJSON


              func GetReceiptsJSON(addr string, offset, limit int) string

RequestReceipt


              func RequestReceipt(cur realm, logHash string)

Ask AI

RequestReceipt is the player-paid leg: ANY signer stages an on-chain consent + payment anchor for one of their own runs (they pay this call's gas). The backend sees the event, verifies the stored log, and fulfills via AttestReceipt. Self-limiting: each request costs the caller gas, and one key slot per (addr, hash). Hash-scoped and game-agnostic on purpose — the verifier, not the player, decides which game the log replays under.

TransferOwnership stages a new owner; it takes effect only after AcceptOwnership is called BY that address (2-step, so a typo can't brick admin).
