TimeStampingChips
TimeStampingChips are compact integrated circuits designed to embed cryptographically verifiable timestamps into data or events. They provide evidence of when a piece of data existed or was created, enabling non-repudiation, auditability, and verifiable history in digital workflows.
Typically, a TimeStampingChip includes a secure element, a real-time clock or trusted time source, tamper-resistant storage,
Applications span digital document authentication and long-term archival, code signing, supply chain provenance, and event logging
Interfaces for these chips vary and commonly include SPI, I2C, USB, or PCIe, enabling integration into devices,
