AI Analysis

●●●BangerBig BrainSolve My ProblemZero to One

Split-key architecture makes forging licenses structurally impossible even if the public server is compromised.

Strengths

•Private signing key lives on a machine that never accepts inbound connections, only initiates outbound tunnels.
•Fixed-width binary license format designed as a permanent ABI for offline verification years later.
•Flat infrastructure cost model that doesn't penalize sales volume like per-seat SaaS competitors.

Weaknesses

•Requires managing two separate servers and tunnel infrastructure instead of a single managed service.
•No mention of Windows or Linux binaries for the offline signer, potentially limiting deployment options.
