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
3Fj4agajZiTqBDDQ9F9KjegDP5b3fwGTxXG5nHS3pumpon 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
