Marcus Dansarie, Independent Consultant at Netnod, discussed Roughtime at the Netnod Meeting 2025. His presentation covered the Roughtime draft protocol for securely providing time to devices—especially in IoT scenarios—without needing an accurate starting time. The presentation also covered how Roughtime can give cryptographic proof of server malfeasance and act as a complement to existing time protocols like NTP and NTS.
