Programmable privacy: balancing confidentiality and transparency in tokenised finance
Written by Alex Bausch, Executive Chairman, 2Tokens
As financial assets migrate on-chain, the inherent transparency of blockchains collides with the confidentiality demands of regulated finance. Programmable privacy, using cryptographic tools such as zero-knowledge proofs, selective disclosure and secure computation, enables compliance, auditability and confidentiality simultaneously. However, scalable tokenised finance depends not on full transparency or secrecy, but on enforceable, rules-based disclosure that aligns market integrity with regulatory oversight. Tokenised finance, where assets, rights and contracts are represented as tokens on distributed ledgers, promises faster settlement, greater accessibility and new forms of capital formation. But it also potentially creates a hard contradiction into the open ledger model: blockchains were designed to be transparent and auditable whilst many financial transactions require confidentiality for competitive, legal or privacy reasons. “Programmable privacy” is the emerging toolkit and d…
