Qualified timestamps: evidentiary value under Art. 41 eIDAS
Last updated: · Leutrim Miftaraj
A qualified electronic timestamp enjoys the legal presumption of accuracy of the date and integrity of the data (Art. 41 eIDAS) — the strongest evidentiary position electronic evidence can reach.
Architecture pattern
Not every entry needs a QTSP call: the chain runs hash-chained in real time; once a day the root is timestamped by a qualified service. One stamp thus anchors thousands of entries — economical and strong in evidence.
Sandbox honesty
Until the QTSP is connected, the export carries a clearly marked sandbox receipt (HMAC) with an identical structure — switching over is a contractual step, not an architectural one. This transparency belongs in every due diligence.
Buyer synergy
Trust-service providers with their own QTS services (such as Swisscom Trust Services) attach the anchoring to their infrastructure — third-party cost becomes product bundling.
Key takeaway
Hash chain plus a daily qualified stamp: maximum evidentiary value at minimal marginal cost.
