Option C — Investment vs Blockchain-Commitment cost (interactive)

Capital-allocation view of the TG3 investment: how much the blockchain commitment (Option C — Etherlink logic + cross-chain escrow) consumes each year, and how much of the invested capital is left for non-BC growth. BC cost = one-off build+audit (Y1) + maintenance + Etherlink fees (messages + bridges), scaling with volume & inflation. Bridge cost defaults to the live Etherlink LayerZero bridge — 0% token fee, USDC & USDT both supported. The €0.5/crossing default is a deliberate ~20× conservative buffer; the measured on-chain median is ~€0.01–0.03/crossing (set to 0.03 for the measured case).
