Mini Hash is a browser-based proof-of-work mining application for the MINI token on Solana, accessible at minihash.app. It runs SHA-256 hashing directly in the user’s browser tab—no downloads or hardware required—and uses the Solana blockhash as a public, verifiable challenge seed every five seconds. The project’s native token contract is deployed on Solana at address 3Fj4agajZiTqBDDQ9F9KjegDP5b3fwGTxXG5nHS3pump, and its token page is viewable on Solscan. According to its official site, mining requires holding 100,000 MINI in the user’s wallet (read-only balance checks every 15 minutes), consumes an energy battery that refills passively, and distributes rewards per tick: 70% to the single best hash (≥6 leading zero bits) and 30% shared among all participants who submitted qualifying hashes. Emission follows a halving schedule—375 MINI per tick, halving every 14 days over six periods—capping total supply at ~178.6M MINI. Key open questions include whether the off-chain reward settlement logic is fully auditable, how difficulty retargeting interacts with Solana’s slot timing under network congestion, and whether the absence of on-chain mining verification exposes payouts to server-side manipulation.

    Mini Hash presents a browser-based SHA-256 mining mechanism for the MINI token on Solana, requiring users to hold 100,000 MINI and run a tab-based miner that consumes energy from a replenishing battery. The design emphasizes transparency—rounds are seeded by Solana blockhashes, hashes are re-verified server-side, and payouts are automated without claim steps (minihash.app and about page). However, no evidence confirms live operation, user traction, or verified on-chain reward distribution. The token contract is reported at 3Fj4agajZiTqBDDQ9F9KjegDP5b3fwGTxXG5nHS3pump on Solana (source_3), but neither transaction history nor treasury balance verification appears in the snapshot. No documentation, repository, or audit is provided. The halving schedule (every 14 days, ending after 84 days) and capped supply (≤178.6M MINI) are stated but uncorroborated. Team identity, development activity, and governance accountability are entirely absent from all sources. The primary thesis—that this is a functional, economically sustainable, and secure proof-of-work layer atop Solana—is asserted but lacks verifiable execution evidence.

    Practical execution brief

    • Delivered: Public-facing frontend, token address, social links (Telegram, X), Solana integration claims.
    • Unverified: Mining rewards, wallet balance checks, jackpot mechanics, difficulty retargeting, treasury solvency, energy refill logic.
    • Next proof: On-chain payout traces, wallet balance snapshots matching claimed treasury checks, public mining logs or round settlement receipts.

    Overall score: 5/10 Confidence: Low

    Mini Hash positions itself as a browser-based CPU mining experience for the MINI token on Solana, requiring no downloads or hardware. Its core loop is a 5-second SHA-256 race per ‘tick’, where users submit hashes tied to their wallet address and the current Solana blockhash — a design that emphasizes verifiability and fairness (web_1, web_2). To begin, users must hold 100,000 MINI off-chain, connect a Solana wallet via signature-only auth, and keep the tab open and active — with energy consumption governed by a battery system that refills passively every two hours (web_2). Rewards are split 70% to the best hash and 30% shared among all participants who clear a 6-bit threshold, with halving every 14 days until emission stops after 84 days (web_2). However, no evidence confirms whether the token supply is actually capped, whether treasury balances match claimed payouts, or whether the reward mechanism has been independently verified. The project lacks documentation, repository links, audits, or on-chain proof of treasury solvency. All claims about difficulty retargeting, jackpot rollovers, and balance checks remain unverified assertions. With no independent corroboration of operational integrity, user retention beyond incentives cannot be assessed — and the primary thesis — that this delivers sustainable value after rewards end — remains unsupported.
