Dapp Game
summary
Company builds a blockchain engine and tried a live blockchain game but finds Ethereum costs blow up — 30–80k KRW gas per tx for simple P2P actions — so on‑chain item trading is impractical. Proposal: an off‑chain Proof of Ownership protocol that uses verifier‑issued nonces and a callback URL nonce scheme to cryptographically prove possession of an NFT without posting every proof on‑chain. Prototype JS demo with websocket servers exists and reduces transaction fees, but it accepts residual double‑registration risk across multiple mainnets.
