Cloud Service (CS) is a Layer 1 Proof-of-Work blockchain (ZelHash / Equihash 125,4, GPU-friendly, 2-minute blocks, 2,000,000,000 max supply) where miners also perform verifiable AI inference through an on-chain Proof of Inference (OPoI) protocol - commit-reveal, staked collateral, random challenges, automatic slashing, paid directly via coinbase. CS Cloud is a live decentralized marketplace where node operators sell compute and users deploy real containerized apps paid in CS. Mainnet live since May 1, 2026. Instantly mineable with lolMiner or our open-source AMD+NVIDIA miner. A bridged SPL version of CS is also available on Solana (this listing), alongside bridged versions on BSC and Polygon.
