The Zaïffer privacy system
Why Privacy Matters in Blockchain Finance
Blockchain transparency is a powerful feature, but it directly conflicts with the confidentiality expected in modern financial systems.
Today, anyone can analyse:
wallet balance
transaction amounts
swap sizes
treasury movements
business relationships
yield allocations
This creates problems for all types of users:
Competitors can track strategies
Wallets expose full financial history
Lack of privacy discourages regulated entities from adopting on-chain finance
Treasury movements become predictable
ENS names leak net worth
Traditional audit models cannot function when sensitive data is globally visible
Market actors can manipulate or front-run operations
Spending and income patterns become public
High-value wallets become security targets
Zaïffer reconciles transparency and privacy by encrypting amounts while leaving addresses visible, enabling compliance, sanctions screening, and auditability.
Why Zama’s technology?
Zaïffer integrates the FHE technology developed by Zama, a leader in applied homomorphic encryption. Zama’s network provides the off-chain computation layer, analogous to how Chainlink provides data oracles. Computations requested by Zaïffer’s smart contracts are processed by a decentralised set of Zama nodes, ensuring no single operator can compromise security.
Performance today achieves confidential transfers in approximately 10 to 15 seconds per operation. This balance between strong encryption and practical usability makes Zama’s FHE uniquely suited for live blockchain applications.
This design ensures that encryption, computation, and verification remain decentralised and verifiable, without reliance on any trusted intermediary.
