4.1.3 Transaction Layer

Zero-Knowledge Proof Creates Fully Anonymous Transactions

Core technologies: zk-SNARKs (Groth16 algorithm, suitable for small-amount transactions) + zk-STARKs (suitable for large-amount/cross-chain transactions), superimposed with amount blinding and address ring signatures.Privacy features: Only transaction completion proofs are stored on the chain, hiding addresses, amounts, and flow directions, and resisting address clustering and quantum attacks.Application scenarios: Oasis DEX anonymous transactions, cross-border asset transfers (avoiding SWIFT information disclosure), RWA asset subscription and redemption (hiding positions and income).
