Feel the energy, relive the atmosphere, and watch our short video recap We are genuinely proud of every builder who went through this season with us and kept building relentlessly during the @colosseum Hackathon The level of dedication, talent, and ambition we saw this season was truly inspiring. Every new cohort proves once again that the Ukrainian @Solana ecosystem is growing stronger, sharper, and more unstoppable with every month • 11 teams pitched their projects • 50 people joined us offline • 35 sleepless days of building, shipping, and pushing beyond limits And today, we are proud to congratulate the winners of our offline Demo Day: 🥇 1st place – @polygamingxyz 🥈 2nd place – @grindurus 🥉 3rd place – @bunnybattle_xyz This is only the beginning.

@by_olesia @colosseum @anon0mesh @RootLens_sol @fairscalexyz @grindurus grinding infrastructure for tokenizing market volatility

teams participating in @colosseum Frontier are building pretty unique apps. some of them: > @anon0mesh - offline p2p crypto payments via mesh networks > @rootlens_sol - anti deepfake camera > @fairscalexyz - reputation infra. their endpoints include checking repayment history & debt - essential for building new age credit products on top > @JurassicFi - tokenizing (?) fossil fuels because why not. these guys didn't give up on their childhood passions

GrindURUS is like Hedge Fund, but on-chain & permissionless

Why this is alpha: • Mint price adapts to system state • Capital flows counter-cyclically • Token = real execution output GRAI = → not a promise → but a reflection of system performance

Yield comes from Grinder: • buy low → sell high • sell high → buy low GRAI captures volatility, not direction This is closer to an index of a trading strategy

GrindURUS and GRAI is new crowdfund mechanics for distributing yield from market volatility. Full mechanics: docs.grindurus.xyz/general/overvi… This thread is TLDR alpha-version of tokenomics 🧵
