Private Transactions, Verifiable Rules Imagine a lending protocol that needs to confirm a borrower meets specific requirements without publishing every detail of their financial history. On a public blockchain, that balance is difficult to achieve. Smart contracts can make rules transparent, but the data used to satisfy those rules may be sensitive. This is where selective disclosure becomes valuable. Instead of revealing an entire financial record, a system can aim to prove a specific claim while keeping unrelated information private. @primus_labs works on technologies that support this direction, including zkTLS for verifiable claims based on web data and FHE for computation on encrypted information. The bigger idea is simple: verification should reveal what a process requires, not automatically expose everything behind it.
