Is @affix-io/sdk-light a zero-knowledge SNARK?
No. SDK Light uses AffixIO Light HMAC proofs in milliseconds. AffixIO still verifies, applies ML-DSA-65 attestation, and anchors Merkle audit on sync.
@affix-io/sdk-light
SDK Light for ordinary devices.
Millisecond local prove without UltraHonk. AffixIO still attests digests with ML-DSA-65 and Merkle audit.
Install
npm install @affix-io/sdk-lightBuilt for phones, kiosks, browsers via host apps, and laptops where UltraHonk is too heavy.
How it differs from affixio
- Local prove uses AffixIO Light HMAC-SHA256, not UltraHonk / Noir / bb.js.
- Dependencies stay on Node crypto, plus optional QR libraries.
- AffixIO sync focuses on digest attest and Merkle by default.
- Light proofs are not SNARKs. They bind a yes or no decision and witness with a shared light key.
Minimal setup
import { AffixLightSDK } from "@affix-io/sdk-light";const sdk = new AffixLightSDK({ apiKey: process.env.AFFIX_API_KEY });Signing behaviour
Every proof is ML-DSA-signed individually at AffixIO. Auto-flush adapts with ingest rate: about every second, with higher batch ceilings when traffic rises above 20 proofs per second.
@affix-io/sdk-light questions
Millisecond prove, edge fit, and attestation on sync.
What hardware fits SDK Light?
Phones, kiosks, POS terminals, and ordinary servers where UltraHonk runtime cost is unacceptable but post-quantum attestation is still required.
How fast is SDK Light prove?
Millisecond local prove using Node crypto only. Adaptive flush to api.affix-io.com runs about every 1 second with higher batch ceilings under heavy ingest.
What CLI ships with SDK Light?
affix-sdk-light binary after npm install @affix-io/sdk-light. Defaults to https://api.affix-io.com.
