Editorial interest 79/100 Selection signal · not a rating of the site

An Estonian technology company presents offline-verifiable timestamping, ephemeris, and supply-chain evidence products.

Landing page captured for the 2026-09-09 issue.

Field notes

The proposed record format is deliberately small: Protosonic describes Cosmic Time Stamp seals as 152-byte artefacts carrying what, when, and where information, readable offline and classified through four verification outcomes. Phoenix Ephemeris supplies the stated sky-and-time consistency layer, while OpenStamps applies plot, harvest, mass-balance, and unit seals to timber and furniture workflows. The homepage also lists offline readers, seal pipelines, channel bots, and industrial-volume tooling.
