HashGame Labs

🚀 HashGame Mainnet Is Officially Live! A new game begins approximately every 10 minutes. No centralized draw system—the outcome is determined directly by the Bitcoin block hash. HashGame uses BTC block hashes as a natural source of randomness, with each Bitcoin block height serving as a unique Game ID. Once a new block is mined, the corresponding result is automatically recorded on-chain, allowing players to verify the outcome and claim rewards immediately. Transparent, immutable, and fully executed by smart contracts. HashGame is more than an on-chain prediction game. It is a prediction gaming protocol that combines Bitcoin’s security, blockchain transparency, and real-time competitive gameplay. 🏆 Two Core Game Modes • Classic Mode: Predict the final character of a BTC block hash • Battle Royale Mode: Use the BTC block hash as a random seed for multiple elimination rounds until the final winner is determined No backend can alter the result. No administrator can interfere. No one can know the outcome in advance. A brand-new on-chain game begins approximately every 10 minutes. HashGame may be the fairest prediction game ever created. Players can earn $HASH Token rewards by participating in HashGame predictions. $HASH is more than a gaming reward—it is the core value asset of the entire HashGameLabs ecosystem: • HashGame and the full OpenPlay product ecosystem • Staking and ecosystem yield mechanisms • Certified prediction market oracle nodes • More on-chain applications and ecosystem utilities Through real gaming demand, expanding ecosystem utility, and long-term incentive mechanisms, $HASH creates a sustainable economic cycle in which players, oracle nodes, and ecosystem participants collectively drive network growth and share the value created by ecosystem expansion. Games create demand. The ecosystem captures value. $HASH powers the entire cycle. #HashGame #HASH #Bitcoin #BTC #GameFi #Web3 #PredictionMarket

Open Market is officially live. Built on OpenPlay’s oracle infrastructure, real-time prediction market odds, and deep liquidity provided by market makers, OpenPlay now has the foundation to support open market creation. Any user can create their own prediction markets based on OpenPlay’s event data, oracle results, and market odds. Currently, market creation is available first to prediction market makers. This feature will gradually be opened to all users in the future. Open Market currently supports football Single and Parlay markets. Users can select 1–5 matches and freely create markets across the following types: 1X2 Correct Score HT/FT Exact Goals Asian Handicap Over/Under In the future, Open Market will support more prediction categories, more market structures, and market creation for any topic. OpenPlay Testnet now supports using $HASH to participate in Open Market. Mainnet support is also coming soon. Everyone can open a market. Everyone can make a market. Everyone can become an actuary. The era of open markets has arrived. Mainnet: openplay.io Testnet: testnet.openplay.io

⚽ Exact Goals is now live on OpenPlay. Football predictions do not always have to be about picking the winner. And they do not always have to be about guessing the exact scoreline. With Exact Goals, everything comes down to one powerful question: How many total goals will be scored in the match? 0 / 1 / 2 / 3 / 4 / 5 / 6 / 7+ From a locked-down 0-goal battle to a wide-open 7+ goal explosion, Exact Goals turns match tempo, attacking intensity, and goal expectations into one simple, direct, high-energy prediction market. Compared with Correct Score, you do not need to hit the exact scoreline. Compared with 1X2, you are not only predicting who wins or loses. You are predicting the heartbeat of the match: Total goals. Every match has its own story. A tactical battle. A defensive grind. A fast start. A late collapse. A full-on attacking storm. Your job is to read the game and choose the script. Exact Goals is now part of the OpenPlay prediction market. Simpler rules. Clearer choices. A more open way to predict football. OpenPlay gives every match more ways to play.

OpenPlay Mainnet is live. No more previews. It begins now. openplay.io

⚔️ Strategy Tournament – Season 9: World Cup Edition 💰 Prize Pool: 5,000 USDT 📈 Dynamic betting limits across tournament stages 🏆 Fully on-chain rankings and settlement The FIFA World Cup returns once every four years, and Season 9 of the Strategy Tournament will officially enter its World Cup Edition. This season will cover all 104 matches of the 2026 FIFA World Cup, where participants compete throughout the entire tournament through prediction skill, bankroll management, risk control, and strategic execution. Unlike traditional prediction contests driven by short-term luck, the World Cup Edition is designed as a long-form strategy competition spanning the entire tournament. As the World Cup progresses from the Group Stage into the knockout rounds, prediction limits will gradually increase. Success is not only about predicting match outcomes, but also about managing capital efficiently and identifying the best risk-reward opportunities at different stages of the tournament. All predictions, settlements, and ranking updates are executed in real time through OpenPlay smart contracts, with every record remaining transparent, verifiable, and immutable on-chain. ——— 📅 Tournament Schedule 2026 FIFA World Cup Total Matches: 104 Registration Deadline: June 27, 2026 Registration remains open throughout the entire Group Stage.

🚀 OpenPlay V2 Is Now Live This is the most significant upgrade since OpenPlay was launched. V2 introduces professional sports prediction markets such as Asian Handicap and Over/Under, while fundamentally redesigning market mechanics, settlement infrastructure, reward systems, and liquidity programs. OpenPlay is taking another major step toward becoming a truly scalable and commercially viable on-chain prediction market. ——— ⚽ Asian Handicap & Over/Under Markets OpenPlay now supports both Asian Handicap and Over/Under markets. Any user can create custom markets for any sporting event, define their own lines, odds, and liquidity parameters. Trading is available both pre-match and in-play, with orders freely listed, canceled, bought, and sold at any time. A truly open prediction marketplace. ——— 🛡️ Compliance-Ready On-Chain Settlement Infrastructure Whether participating in pool-based markets such as 1X2, Correct Score, and HT/FT, or user-created Asian Handicap and Over/Under markets: • Every trade, market creation, order match, and fund movement is permanently recorded on-chain • Wallet addresses, payment assets, and transaction routes are fully verifiable and traceable • In the event of postponed, canceled, or invalid matches, 100% of principal is automatically refunded through the original payment route using the original asset type For user-created markets, even when positions are resold multiple times, settlement is always executed using the original payment asset. This ensures transparent fund flows while minimizing potential compliance and AML concerns associated with cross-asset settlements. ——— 💎 Single-Sided Fee Model One of the most popular features of OpenPlay. Unlike most prediction markets, OpenPlay charges a 5% fee only on profits. User principal is never charged. • 2% allocated to Oracle Nodes • 1.5% allocated to Referrers • The remainder supports ecosystem growth For users, this translates into an effective payout rate of approximately 97.5%. Even in ultra-low-odds markets, winners retain nearly the full value of their expected returns rather than having profits significantly reduced by traditional two-sided fee structures. ——— 🏆 Season-Based Reward System Sports events differ fundamentally from BTC block prediction markets. Matches may be postponed, canceled, or interrupted, creating unique settlement challenges. To address this, OpenPlay V2 introduces a fully redesigned reward framework. All rewards are calculated exclusively from confirmed and valid match results: • Betting Token Rewards • Season Leaderboards Each season lasts 7 days. At the end of every season, Oracle Nodes verify match outcomes, while the protocol automatically excludes invalid or abnormal events from reward calculations. This mechanism effectively prevents reward farming, point manipulation, referral abuse, and other forms of exploitation. ——— 🤝 Referral Rewards OpenPlay referral rewards are not generated when users place bets. Instead, they are distributed from actual platform fee revenue. Since OpenPlay only charges fees on user profits, referral rewards are generated only when a winning user claims their payout. This design fully aligns referral incentives with real platform revenue and prevents abuse arising from canceled events, invalid matches, or abnormal betting activity. The result is a healthier and more sustainable referral ecosystem. ——— 🌊 Market Maker Program To ensure deep and sustainable liquidity, OpenPlay V2 introduces the Market Maker Program. Stake 100,000 USDO, USDT, or USDC to become an official Market Maker. Benefits include: • Effective payout rates of up to approximately 99.5% • One Oracle Node allocation (equivalent to ecosystem rights associated with 250,000 HASH) Once 10,000,000 points have been accumulated, Market Makers may unstake and withdraw 100% of their principal at any time. After unstaking, Market Maker status will automatically terminate. However, the Oracle Node allocation granted during participation remains permanently retained. ——— ⚡ More Upgrades V2 also delivers substantial smart contract optimizations, performance improvements, and user experience enhancements. From market creation and order matching to settlement, reward distribution, and user interaction, every layer of the platform has been refined. OpenPlay V2 is more than a version upgrade. It marks the beginning of the next stage for a truly open, transparent, scalable, and compliance-oriented on-chain prediction market.

🚀 OpenPlay Oracle Public Test is Now Live We’re excited to announce that OpenPlay Oracle has officially entered its Public Test phase. OpenPlay Oracle is the world’s first decentralized oracle infrastructure purpose-built for sports and esports data, designed to deliver high-frequency, verifiable, and trust-minimized data support for the next generation of on-chain prediction markets. ——— 🔗 Redefining the Oracle Network Unlike traditional oracle systems limited by node centralization, opaque data sources, and high participation barriers, OpenPlay introduces a fully open network architecture: • Up to 1,000 community-owned node slots are available, all held and operated by community members • Each node is a publicly verifiable EVM wallet address • Users can obtain a node slot by paying a fixed amount of $HASH (not staking, non-refundable) • The entire data submission and validation process is fully transparent and traceable on-chain ——— ⚙️ Native Integration: Oracle + Prediction Market OpenPlay is not just an oracle.
