About

Project

OpenTimeStats is a Flask web application that submits files to OpenTimestamps calendar servers, tracks how long each calendar takes to produce a Bitcoin blockchain attestation, and visualizes those results over time.

The project automates timestamp creation and proof upgrades, stores request and attestation history, and exposes both a web UI and JSON API for monitoring calendar responsiveness.
