# Key Concepts and Terminologies

This section outlines fundamental concepts and terminologies that underpin the Traceva protocol. It introduces key cryptographic principles, technical standards, and architectural components essential for understanding how Traceva achieves privacy, security, autonomy, and interoperability. Specifically, the following concepts will be discussed in detail:

* **Zero-Knowledge Proofs (zk-SNARKs/STARKs):**\
  Cryptographic proofs allowing validation of information without revealing underlying sensitive data
* **Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs):**\
  Standards enabling decentralized and user-controlled digital identity management, credential issuance, and validation.
* **Stealth Addresses and zkReceipts:**\
  Techniques for anonymous financial interactions and cryptographically verifiable transactions without revealing transactional metadata.
* **Agent Autonomy and Delegation:**\
  Mechanisms enabling autonomous agents to execute actions and securely perform delegated tasks without compromising user privacy.
* **Modular Layer-2 (L2) Scaling Solutions:**\
  Strategies and technologies to improve scalability, reduce costs, and enhance efficiency within decentralized blockchain environments.
