The platform uses the most advanced methods to protect user data and ensure complete confidentiality in all interactions. This section outlines the security mechanisms that make NORA a safe place for communication and managing digital assets. #### **6.1. End-to-End Encryption (E2EE)** All communication on NORA is secured using **end-to-end encryption (E2EE)**. This means that only the sender and recipient can decrypt messages, ensuring that no one— not even the platform itself—can access the content. NORA uses the most robust encryption protocols to ensure complete privacy. * **AES-256**: NORA employs **AES-256** encryption, one of the strongest available standards to keep data secure. #### **6.2. Decentralized Identifiers (DID)** NORA utilizes **Decentralized Identifiers (DIDs)** for managing user identities. This means that all user data is stored on the **blockchain**, not centralized databases, giving users complete control over their information. * **Self-Sovereign Identity (SSI)**: Users can create and manage their digital identities without relying on intermediaries. All data remains private and under the user’s control. #### **6.3. Secure Transactions** NORA ensures that all transactions are conducted securely through **smart contracts** and **secure wallets**. All financial operations, including token transfers and DeFi participation, are processed through secure channels. * **Secure Wallets**: NORA integrates with popular crypto wallets, allowing users to retain control over their assets while ensuring that all operations are secured with multi-layered protection. #### **6.4. Authentication Protocols** To secure user access to the platform, NORA implements **two-factor authentication (2FA)** and other advanced methods, such as **biometric authentication** and **hardware wallet support**. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://nora-2.gitbook.io/nora-docs/privacy-and-security.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
