Financial Transaction API with Cryptographic Idempotency

cryptography fintech idempotency security
Prompt
Create a secure financial transaction API that guarantees exactly-once processing using advanced cryptographic techniques. Implement an idempotency mechanism using SHA3-512 request signatures, a distributed transaction log with blockchain-like immutability, and a zero-knowledge proof system to validate transaction integrity without revealing sensitive details. Design robust error handling for network interruptions and partial transaction states.
