RLN (Rate Limiting Nullifier) implementation for Waku

Context-agnostic Poseidon nullifier derivation (poseidon2(toField(sub), contextId)) plus the server-side replay/uniqueness store contract.

Encoder/Decoder for Mbiz Chat

Seal — ZK auth circuit for Lemma dashboard Proof-based sign-in. Proves knowledge of a secret pre-image without revealing the secret or its hash (v2: Poseidon nullifier).

SDK to interact with the rent-free nullifier program on Solana

This is a circuit that takes a semaphore identity and a nullifier in, and generates an identity commitment and the hash of the identity commitment and nullifier together.

Client library for generating and using RLN ZK proofs, is a forked repo from main Rate-Limiting-Nullifier/rlnjs to make it work with Cryptkeeper Browser Extension using `@cryptkeeperzk/snarkjs` and `@cryptkeeperzk/ffjavascript`

A wrapper of the [RLN](https://github.com/Rate-Limiting-Nullifier) protocol, which enables PCD SDK-conforming applications to request, prove, and verify RLN proofs.

Self-contained Semaphore v3 + RLN (rate-limiting nullifier) package. Privately bundles Semaphore v3 + rlnjs 3.2.0 + the depth-20 circuit and exposes a bigint-only surface: rate commitment, RLN nullifier, Shamir recovery, signal hash, the depth-20 Merkle r

Aroha caller-uniqueness layer — KYC issuer trust and Chaum-Pedersen nullifier proofs for Sybil-resistant reputation

Groth16 ZK-SNARK circuits for GrimSwap - Poseidon Merkle tree proofs and nullifier verification for private Uniswap v4 swaps

Client library for generating and using RLN ZK proofs.

TypeScript primitives for building privacy protocols on Solana. Merkle trees, Poseidon commitments, nullifiers, and proof format conversion.

Client library for generating and using RLN ZK proofs.

Zero knowledge proof based UTXO tokens toolkit for fungible or non-fungible assets

A Semaphore and MicroMix client library

No description provided.

A PCD representing a proof of ownership of an EdDSA-signed ticket. The prover is able to prove ownership of a ticket corresponding to their semaphore identity, and optionally prove the ticket corresponds to one of a list of valid events. The prover can ke

Commitment-only AgreementRegistry SDK. Owns AgreementCredential shape (PD-22) + commitment math + bilateral status transitions + joint-assertion gateway.

The primary functions of the world state package are to maintain the collection of Merkle Trees comprising the global state of the system and to offer an interface with which the trees can be queried.
