Ephemera

The operator side of every comparison comes from files this project caught before they were replaced. Each cycle is hashed file by file into one Merkle root, the root is stamped into the Bitcoin blockchain through OpenTimestamps, and the manifest plus ten files chosen by the root itself are pushed into the Wayback Machine so an independent copy exists that this project does not control.

As of 2026-10-29 18:21 UTC: 190 cycles, 190 complete with roots, 190 anchored in Bitcoin, 44 with a defect in the independent copy. Source bytes archived: 4,318 GB across 2,127,330 files as served. Stored gzipped as 1,776 GB, of which 28 GB is on the poller's disk and 1,748 GB exists only in cold object storage. Cadence holds, meaning a set served longer than nine hours while the poller watched: 15. A further 3 such intervals fell while the poller was down and are not counted as a hold. Poller heartbeat coverage over the last 24 hours: 100.0%. This project exists because SpaceX publishes the feed openly.

Method: built from each cycle's cycle.json, witness.json and ship.json in the poller's spool; coverage is the fraction of the last 24 h's minutes with a watcher heartbeat under 10 minutes old (D18); a cadence hold is a manifest first-seen gap over 9 h; source bytes are the responses as served, stored bytes are the gzipped archive objects the shipper recorded. Poller: A (a datacentre host in the EU; the home poller was retired on 3 Oct 2026).

A cycle still pulling at midnight is left out of that day's root and stays out. It keeps its own cycle root and its own OpenTimestamps proof, so nothing is unwitnessed, but it sits under no daily root.
