# Cryptographic Components

ZOKA's codebase includes:

* Ristretto255-based private wallet operations.
* BIP39 mnemonic-based recovery flows.
* Commitments and nullifiers for private transfer accounting.
* zk-SNARK proof infrastructure.
* Bulletproof-style range proof components for private value constraints.
* Encrypted wallet storage.

Implementation details can change across releases, so integration work should track the active release branch and protocol activation heights.

## How They Fit Together

Commitments let the chain account for private values without publishing the plain amount. Nullifiers prevent double spends by making spent notes detectable without revealing the original note owner. zk-SNARK verification lets a node check private transaction validity against the active circuit rules.

Wallet recovery and scanning are separate concerns. A recovery phrase restores wallet identity, while scan material lets the wallet detect relevant encrypted outputs in chain data. Neither belongs in a public explorer query or support ticket.

## Release-Critical Material

Trusted setup or CRS files, wallet derivation code, proof verification code, and activation-height logic must be treated as release-critical. Development setup paths and seeded test setup must not be reused for production-value networks.
