Unstoppable Domains Launches .​horizen Blockchain Domains with Onchain Features

**Reverse lookup zones** are a critical but often overlooked part of DNS infrastructure. Unlike forward lookups that translate domain names to IP addresses, reverse zones do the opposite using **PTR records**. These zones live under special **.arpa domains** and serve three essential functions: - **Email validation** - verifying sender authenticity - **Spam filtering** - blocking suspicious sources - **Security log readability** - making IP addresses human-readable While forward zones use A records (IPv4) and AAAA records (IPv6) to let you type domains instead of IP addresses, reverse zones ensure those connections can be verified and traced back. This bidirectional system is fundamental to internet security and email deliverability.

A security reminder has been issued emphasizing the importance of enabling two-factor authentication (2FA) on accounts. **Quick Setup Steps:** - Navigate to Account Settings - Locate Security section - Enable Two Factor Authentication - Scan the QR code with your authenticator app Two-factor authentication adds an essential security layer by requiring a second verification method beyond your password. This helps protect your account and domains from unauthorized access. Take a few minutes today to enable 2FA if you haven't already done so.

Horizen has introduced **.horizen**, a dedicated naming system for its ecosystem. The domain structure allows projects, tools, research initiatives, and resources to operate under names that immediately identify them as part of Horizen—eliminating the need for additional context or explanation. **Key features:** - Built specifically for the Horizen network - Provides a shared naming layer for applications and tools - Designed for active builders and contributors deploying within the ecosystem The system functions as a blockchain domain solution, enabling users to resolve cryptocurrency addresses and decentralized websites through a unified naming convention.

A new Web3-only namespace has launched for developers in the Horizen ecosystem, emphasizing practical privacy implementation. **Key Context:** - Privacy tools must function in real-world conditions where applications handle value and coordinate users - Theoretical privacy solutions often fail when deployed in public environments - The namespace targets builders working within the [@horizenglobal](https://twitter.com/horizenglobal) ecosystem This launch follows ongoing discussions about privacy as a foundational requirement for Web3, not just a feature. The focus is on privacy that survives actual use cases rather than laboratory conditions.
