tardygrada vs attestix

tardygrada: Tardygrada is a programming language that compiles to MCP servers, where every value carries cryptographic proof of its creator, creation time, and integrity. It guarantees integrity via mprotect, SHA-256, ed25519, and BFT consensus (proven in Coq), provenance with signed metadata, and a full audit trail. However, it does not guarantee truth; it only ensures the value has not been changed, providing 100% proof even after 100 handoffs among agents.; attestix: Attestix provides cryptographically verifiable proof for AI agents to comply with the EU AI Act. It combines agent identity, compliance automation, and verifiable credentials in one open-source protocol. With 47 MCP tools across 9 modules, it enables identity creation, compliance checks, and audit trails.
