Most people hear "privacy" and think "anonymity." for institutional finance, those are not the same thing and mixing them up is why the conversation keeps going in circles. At BNB Seoul, @primus_labs co-founder and CEO @xxiang_xie put the case directly: "privacy is the final piece of the puzzle for blockchain finance." The framework behind that line rests on two principles worth understanding. 1. Confidentiality over anonymity Public blockchains expose trade sizes, balances and positions to anyone watching. for a regulated institution, that is an operational and information risk. a fund cannot build or unwind a position in public without revealing its strategy. The usual instinct is to hide who is transacting. primus's position is different: hide the sensitive values, such as reserve balances, transfer volumes and portfolio positions, rather than the identities involved. That matters because institutions are not trying to disappear. they are known, regulated entities with obligations. what they need is to keep commercial information from becoming public by default. 2. Selective disclosure The second principle is to keep state confidential by default, then allow audited disclosure when regulators or oversight require it, using cryptographic proofs. So confidentiality does not mean opacity toward everyone. It means control over who sees what and when. the default is private. disclosure is deliberate, scoped and provable. Together, the two ideas describe a model that institutions and regulators can both work with: known participants, protected values and disclosure on demand. How Primus builds toward this As presented at BNB Seoul, the approach sits in a Data Verification and Computation layer on BNB Chain with three components: - zkTLS: turns authenticated web data, like custodian attestations or corporate reserve data, into onchain proofs without exposing credentials or raw data. - FHE with zkVM or TEE: lets smart contracts update balances and run financial logic on encrypted inputs. - Institutional Proof-of-Reserves: combines onchain holdings with offchain custodian reserves for ongoing solvency verification. Primus is working with BNB Chain and Unitas Labs on native confidential finance products for BNB Smart Chain, aimed at dApps, AI agents and institutions. Honest limits, because the same panel raised them: - FHE and zero-knowledge proofs add computational overhead and latency. Scaling will need hardware acceleration and lower costs. - Regulators still need to confirm whether automated attestations meet audit standards. - Primus describes moving toward live compliance integrations with institutional partners. That is a direction, not a finished outcome and nothing here is a compliance certification. The takeaway is a better question than "should finance be private or transparent?" ask instead: what should be confidential, from whom and under what conditions can it be disclosed? Confidential by default. Provable on demand. Known participants, protected values.
