Last week, a friend who makes industrial parts complained to me, looking helpless. Her company supplies a large factory, which requires full-process traceability. Not only do they want to see the finished product inspection report, but they also want to see raw material procurement records, quality inspection data during the production process, and even workers' operation logs. 'I understand that the large factory wants quality control, but the formula ratios, process parameters, and supplier channels are all trade secrets. Revealing everything is like giving away our family's assets. If competitors find out, can I still survive?'

I told her that your problem is the same as the logic behind MoneyGram and Vodafone choosing Midnight. MoneyGram does cross-border remittances in over 200 countries, and customer information cannot be exposed, but regulation must be auditable. Vodafone's Pairpoint facilitates autonomous transactions for IoT devices, where your car pays for parking itself, but it cannot let the whole world see where you are parked; however, the device must prove 'I am qualified to pay.' Their needs are exactly the same as your company's: compliance and confidentiality are required.@MidnightNetwork

A friend asked how to achieve this specifically. I said the core is zero-knowledge proof. You can prove to large manufacturers that 'the raw materials for this batch of parts were sourced from compliant suppliers, the production process meets standards, and the quality inspection was passed,' but you don't have to reveal the formula ratios, purchase prices, or worker operation logs. The large manufacturers can verify the conclusions but cannot see the trade secrets. This logic is called 'selective disclosure'—it's not about hiding everything or exposing everything, but only revealing what needs to be revealed.

For example, you can prove to clients that 'the source of the materials for this batch is compliant,' but you don't have to reveal who the supplier is or how much you paid for it. You can prove that 'no banned substances were used in the production process,' but you don't have to disclose the complete formula.

She asked if this technology can be used now. I said the Midnight mainnet is going live in the next few days, and Google Cloud is also supporting it. Moreover, Midnight uses the Compact language, which is based on TypeScript, making it easy for developers to get started. Teams are already doing proofs of concept for supply chain traceability on Midnight, and once the ecosystem expands, there will be no more 'running naked.'$NIGHT #night

She said after listening, 'Next time when discussing cooperation, I'll ask the other party if they can use this set of solutions. Otherwise, every audit feels like running naked, which is too uncomfortable.'
