nobulex vs SchemaPin

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.; SchemaPin: SchemaPin enables tool developers to sign schemas and skill folders with ECDSA P-256 keys, and AI agents to verify schema integrity. Public keys are discovered via .well-known/schemapin.json, and Trust-On-First-Use pinning prevents key substitution. It supports key revocation, trust bundles, and multiple languages (Python, JS, Go, Rust).
