Why AI Agents Need What Humans Invented Millennia Ago: Digital Signatures

While AI agents proliferate across production systems, the industry has overlooked one of humanity's oldest mechanisms for establishing accountability: the signature. Without cryptographic proof embedded in agent-tool interactions, organizations cannot audit actions, verify authorization, or ensure compliance—creating significant security blind spots. Signet addresses this critical gap by introducing Ed25519-based identity and tamper-evident audit logs, establishing digital signing as a foundational requirement for production-grade AI systems.
