RobotMasters is a Solana on-chain robot-fighting engine built on a custom bytecode VM, shipped as two parallel Anchor programs, one storing full state on-chain, the other using Bolt ECS plus MagicBlock ephemeral rollups for delegated state Repo profile: dual Anchor programs, bytecode VM, Bolt ECS + MagicBlock integration. That MagicBlock approach is the exact stack used by Radar's 1st-place Gaming winner Supersize (0.076) and Breakout's 4th-place Block Stranding (0.081) Supersize, 1st Place Gaming, Radar hackathon, similarity 0.076 Block Stranding, 4th Place Gaming, Breakout hackathon, similarity 0.081, giving genuine winner-DNA overlap (winnerSimilarity 78) despite no confirmed win of its own. The niche is crowded, 146 topical neighbors and live rivals like Air-Combat On-Chain and Deep Dungeon Duel already ship comparable on-chain combat loops Air-Combat On-Chain, live real-time on-chain combat game, similarity 0.057 Deep Dungeon Duel, live on-chain PvP roguelike, similarity 0.050. Execution lags the ambition: no CI, one thin test file, boilerplate Vite READMEs in the frontend sub-apps, and two unfinished/duplicate Anchor programs point to an abandoned migration (techQuality 58, the weakest strong dimension after momentum). Momentum is also thin: 138 commits from a single contributor over three months with zero stars GitHub metadata: 138 commits, 1 contributor, 0 stars, Feb-May 2025 activity window. The bytecode-scripted mechanic is a real differentiator, but this reads as a promising prototype rather than an arena-ready submission. Next move: finish the robotmasters/ migration, add real coverage to the MagicBlock path, and ship a deployed build to convert the strong technical concept into proof.
