nobulex vs Sentinelgate

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.; Sentinelgate: SentinelGate is a self-hosted, container-native, zero-lock-in proxy that intercepts every action of an AI agent before it executes, applying deterministic rules to block unauthorized tool calls, shell commands, and file operations. It provides a full audit trail, content scanning, and session-aware policies, and works with any MCP-compatible client or sandbox.
