nobulex vs tardygrada

nobulex: Nobulex provides a credit and trust protocol for autonomous AI agents. Agents earn Trust Capital through cryptographically verified actions, enabling tiered access levels. The system ensures accountability without trust, using tamper-proof receipts and a flywheel mechanism.; 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.
