ar vs aicanvas

ar: Agent Receipts is an open protocol for generating cryptographically signed audit trails for AI agent actions. It provides SDKs in Go, TypeScript, and Python, plus an MCP proxy that intercepts and signs agent tool calls using Ed25519 signatures. The receipts can be verified independently, enabling accountability and traceability in agentic systems.; aicanvas: AI Canvas is an open-core registry of animated React components, composed page blocks, design systems and templates. They are installed as real source code in your project rather than as a dependency, with one shadcn CLI command or through an MCP server.
