Examples

Each example is a small application with its own README, trust model and tests, which CI runs on every change. None needs a network or an external service.

A browser's own tamper-evident log

A browser keeps its own tamper-evident log in IndexedDB, signed by a device key no script can export, shared safely between tabs. Runs on browsers.

Session receipts: a record neither side can rewrite

The browser logs every exchange with the server; the server witnesses the log and commits it to S3-compatible storage. Runs on browsers, Node.js, Bun and Deno.

A notary with offline-verifiable receipts

A notary: it logs a document's SHA-256 digest with its submitter's signature, and returns a receipt that anyone can verify offline. Runs on Node.js, Bun and Deno.

A public log server, on any SQLite, on Node, Bun or Deno

A public transparency log server: POST /add and the tlog-tiles read API on any SQLite, from one source on Node, Bun and Deno. Runs on Node.js, Bun and Deno.

A monitor that catches forks and rollbacks

A monitor that follows a remote transparency log, proves every new checkpoint consistent with the last, and reports a fork or rollback loudly. Runs on Node.js, Bun and Deno.

The log server at the edge: a Cloudflare Worker

The log server example as a Cloudflare Worker, one deployment target among several: the same routes, on a SQLite-backed Durable Object. Runs on Cloudflare Workers.

To run one, build the library at the repository root, then run its ci script in its directory. The sources are in examples/.
