@shyware/sdk

Structurally anonymous distributed-ledger protocol SDK.

Non-linkability by write architecture — not policy. One invariant, thirteen embodiments.

What it does

Every submission atomically writes two permanently disjoint records:

• List 1 — anonymous payload record: direction-free identifier, sealed content. No participant identity.
• List 2 — participant registry record: identity hash. No payload, no submission identifier.

No join key between List 1 and List 2 is ever written to canonical state. The rejection predicate refuses any state transition that would create one. Identity-to-payload linkage is non-representable by write architecture — not hidden, not encrypted, not gated.

Installation

npm install @shyware/sdk

Requires a Commercial License Agreement for production deployment. See shyware.fyi/legal for terms.

Publishing

This package is published from the npm account shyware, which uses auth-and-writes two-factor auth with npm web/passkey authentication on the user's MacBook.

Release flow:

npm version minor # or npm version patch
npm pack --dry-run
npm publish --access public
npm view @shyware/sdk version dist-tags --json
git push origin main --follow-tags

Run npm publish --access public in an interactive TTY. When npm asks to press Enter to authenticate in the browser, press Enter and have the user approve the passkey prompt on the MacBook. Do not ask for a numeric OTP unless npm explicitly asks for one after web/passkey auth fails.

Quick start

import { createVotingClient } from '@shyware/sdk/clients/voting';

const client = createVotingClient({ /* shyconfig */ });
